1. COMPONENT DESCRIPTIONS

1.1 Primary Control Valves

1.1.1 Diaphragm Differential Deluge Value

1.1.1.1 General

The Model A 2½ (65mm) Deluge Valve is a hydraulic, direct diaphragm actuated valve designed for use as a primary control valve in a fire protection system. Diaphragm actuation allows the valve to be reset by external hydraulic means, thereby eliminating the process of removing the cover plate. The design features a limited compression piston which seals against a replaceable rubber seat retained in the valve body. This feature prevents localized compression set of the rubber seal. Compression set of the clapper seal in other valves require exact clapper-to-seat alignment when resetting, and may result in leakage past the seal. Limited compression is accomplished by a metal retainer ring which allows the piston to squeeze the seal a predetermined fixed amount, regardless of inlet supply pressure. The valve design also features a separately replaceable, molded diaphragm which incorporates an O-ring ends configuration on the inside and outside sealing diameters. The O-ring ends provide more positive retention, clamping and sealing of the diaphragm to the piston and to the valve body.

1.1.1.2 Operation

The Model A 2½ (65mm) Deluge Valve is a quick opening type consisting of (3) chambers: top (pressurized), outlet (normally dry) and inlet (pressurized). The (3) chambers are isolated from each other by the diaphragm piston and compression limited seat seal. In the closed position (Figure 1), supply pressure in the top chamber acts across the diaphragm and piston holding the piston on the seat against inlet supply pressure. The diaphragm pressure area is greater than the seat pressure area providing a closing force differential of about 3 to 1. When a fire is detected, the top chamber is vented to atmosphere through the outlet port via an opened releasing device.

The top chamber pressure cannot be replenished through the restricted inlet port as rapidly as it is vented from the outlet port, and the chamber pressure falls rapidly. When the top chamber pressure reaches about 1 3 the supply pressure, the upward force of the supply pressure, acting on the piston face, overcomes the downward force on the diaphragm, and the piston moves to an open position (Figure 2). When the piston has opened, water flows from the supply through the deluge valve into the sprinkler system and through the alarm outlet to the alarm devices. The valve maintains the open position until every open releasing device is closed. CAUTION -- THE RELEASING DEVICE MUST BE MAINTAINED OPEN TO PREVENT AUTOMATIC CLOSING OF THE MODEL A DELUGE VALVE.

Figure 2 Model A Deluge Valve in OPEN Position

1.1.1.3 Detection and Actuation

In general, the Model A 2½ (65mm) Deluge Valve can be released by any listed or approved device which opens sufficiently to vent the top chamber. The releasing device is connected to the top chamber outlet port and when this device opens to vent the top chamber, the deluge valve promptly opens. Typical releasing devices include hydraulic manual emergency stations, pilot line sprinklers, dry pilot actuators, and solenoid valves. Pilot line sprinklers perform both thermal detection and rel easing functions, and no additional detectors are required when these devices are used. A solenoid valve releasing device enables the use of various types of electrical fire detection devices. Typical detection devices include electrical manual emergency stations and thermal, flame, and ionization or photoelectric smoke detectors. A releasing control panel (See Section 1.4.1) is required with a solenoid valve releasing device.

1.1.2 Lever Differential Deluge Valve

1.1.2.1 General

Models B and BX Deluge Valves are hydraulically-operated differential type valves designed for use as primary control valves in fire protection systems. Both models are easily reset; however, the Model B requires cover plate removal, while the Model BX may conveniently be reset externally without removing the cover plate. Field replaceable bronze seat rings are incorporated in both models, and the push-rod assembly, lever and clapper assembly are all replaceable without removing the valve from the riser. The clapper assembly has been designed with a limited compression feature. This is beneficial to the rubber facing which relies on pressure from the supply water to inflate the rubber facing, thereby providi ng the sealing force between the facing and the seat.

Figure 3 Model BX Deluge Valve in Closed Position

1.1.2.2 Operation

The Model BX Deluge Valve (closed) and the Model B Deluge Valve (open) are shown in Figures 3 and 4, respectively. In the normally closed position, water supply simultaneously exerts pressure on the underside of the clapper and in the push-rod chamber. The resulting chamber pressure force directed by the push-rod against the differential lever is to hold the clapper in the closed position against the supply pressure.

01/01

The Reliable Automatic Sprinkler Co., Inc., 525 North MacQuesten Parkway, Mount Vernon, New York 10552

12

When the push rod chamber is vented, the chamber pressure cannot be maintained through the inlet restriction and the push-rod chamber pressure falls rapidly. When the chamber pressure reaches about one half of the supply pressure, the upward force of the supply pressure acting on the clapper overcomes the downward force of the differential lever and the clapper opens. As water flows through the deluge valve into the system piping, it also flows through the deluge valve alarm outlet to the alarm devices. The differential lever also serves as a latch, preventing the clapper from returning to the closed position, when water flow ceases. The Model B Deluge Valve is easily reset when pressure is vented from the push-rod chamber by simply removing the cover plate, restoring the clapper and differential lever to their set positions and reinstalling the cover plate. Resetting the Model BX Deluge Valve only Figure 4 Model BX Deluge Valve in OPEN Position requires a 20° turn of the external reset knob to restore the lever and clapper without removing the cover plate. Note: Do not attempt to turn the knob when the Push-Rod Chamber is pressurized. The external reset feature provides a means for convenient, economical system testing which is essential in a good maintenance program. The external reset feature does not, however, eliminate the need for periodic cleaning and inspection of the internal valve parts.

1.1.2.3 Detection and Actuation

In general, the Models B and BX Deluge Valves can be released by any listed or approved device which opens sufficiently to vent the push rod chamber. The releasing device is connected to the push rod chamber outlet and when this device opens to vent the chamber, the deluge valve promptly opens. Typical releasing devices include hydraulic manual emergency stations, wet or dry pilot line sprinklers, dry pilot actuators, and solenoid valves. Pilot line sprinklers perform both thermal detection and releasing functions, and no additional detectors are required when these devices are used. A solenoid valve releasing device enables the use of various types of electrical fire detection devices. Typi cal detection devices include electrical manual emergency stations and thermal, flame and ionization or photoelectric smoke detectors. A releasing control panel (See Section 1.4.1) is required with a solenoid valve releasing device.

1.1.3 Differential Dry Pipe Valve

1.1.3.1 General

Models A and D Dry Pipe Valves are pneumatically activated valves designed for use as primary control valves in fire protection systems. Following each operation (releasing) of a dry pipe valve, the cover plate must be removed to reset the valve. Automatic or external resetting features are not available on these dry pipe valves.

1.1.3.2 Operation

Features and the operation and installation details for RELIABLE Dry Pipe Valves are described in Bulletins 352 and 353 (2½ Model A) and Bulletins 350 and 351 (4 & 6 Model D).

1.1.3.3 Detection and Actuation

Dry pipe valves are occasionally used in some types of preaction systems and discussions of such applications are contained in Sections 3.3.1 and 3.4.1 of this document.

1.2 Control Valve Releasing Devices

1.2.1 Sprinkler Head (Hydraulic)

A closed sprinkler head becomes a primary control valve releasing device when it is located in a pipe (pilot) line that is attached to the outlet from the hydraulically pressurized top or push rod chamber of a control valve. This arrangement is usually described as hydraulic (wet pilot) actuation of a system in which the pilot line sprinklers serve the dual purpose of being control valve releasing devices, as well as thermal detectors. See Section 1.2.1. and RELIABLE Bulletins 131 and 136 for more information. Also, refer to RELIABLE Bulletins 501 and 503, and to the Hydraulic Data (Section 4.1) for detailed information on pilot line elevation and length limitations.

The Reliable Automatic Sprinkler Co., Inc., 525 North MacQuesten Parkway, Mount Vernon, New York 10552

17

1.2.2 Dry Pilot Actuator (Pneumatic)

A dry pilot actuator is a primary control valve releasing device located in the pipe line attached to the outlet from the top or push rod chamber of a control valve. This releasing device separates water pressure from air pressure when it is necessary to use air in a pilot line of sprinklers. A dry pilot actuator is similar to a differential dry pipe valve; a moderate level of air pressure holds the device closed against a considerably higher level of water pressure. The following table provides various pressure level relationships for the Model A Dry Pilot Actuator. A closed dry pilot actuator will maintain the water pressure that is holding a control valve closed. Whenever one (1) or more dry pilot sprinklers (thermal detectors) operate, the loss of air pressure in the pilot line causes the dry pilot actuator to open, discharging water pressure to a drain and thereby releasing the control valve.

Water Pressure Maximum psi 20 50 75 100 125 150 175 bar 1,4 3,4 5,2 6,9 8,6 10,3 12,1 Pneumatic Pressure to be Pumped Into Dry Pilot Line Not Less Than psi 10 15 20 25 30 35 40 bar 0,7 1,0 1,4 1,7 2,1 2,4 2,8 Not More Than psi 20 25 30 35 40 45 50 bar 1,4 1,7 2,1 2,4 2,8 3,1 3,4

NOTE: A higher pressure may be necessary to initially seat the dry pilot actuator. The arrangement just described is usually referred to as pneumatic actuation of a system in which the pilot line sprinklers are thermal detectors and the dry pilot actuator is the releasing device. Dry pilot line releasing is used whenever freezing conditions would prevent the use of wet pilot line releasing, or when the ambient temperature can exceed 150°F (65°C). Dry pilot line releasing must also be used when the elevation or length of wet pilot lines above the control valve becomes too large. Refer to RELIABLE Bulletins 501 and 503, and to the Hydraulic Data (Section 4.1) for detailed information on wet pilot line elevation and length limitations.

1.2.3 Solenoid Valve (Electric)

A normally closed solenoid valve is a primary control valve releasing device located in the pipe li ne attached to the outlet from the top or push rod chamber of a control valve. The solenoid valve releasing device separates water pressure in these chambers from atmospheric air pressure in a drain line. Whenever sufficient electrical current is provided for energizing the solenoid coil, this releasi ng valve opens and discharges water pressure from the chamber to a drain, thereby releasing the control valve. This arrangement is referred to as electrical actuation of a system in which electrical heat, smoke, light and manual detectors are used in conjunction with a solenoid valve releasing device.

1.2.4 Manual Emergency Pull Station

1.2.4.1 Manual Pull Station (Hydraulic)

A manual pull station is a normally closed, quick opening valve which is a primary control valve releasing device when it is located in the piping of a wet or line pilot line of sprinklers. It di scharges water or air pressure from the pilot line, as an operated pilot line sprinkler would do. The quick opening releasing valve is enclosed in an appropriately marked box which has a cover that must be opened by overcoming a breakable strut. Once opened, the cover cannot remain closed without first replacing the broken strut. RELIABLE Bulletin 506 gives detailed information on the Model A Manual Emergency Pul l Box (Station).

01/01

The Reliable Automatic Sprinkler Co., Inc., 525 North MacQuesten Parkway, Mount Vernon, New York 10552

20 1.2.4.2 Manual Emergency Stations (Electric)

A manual emergency station is used to electrically activate the solenoid valve releasing device whi ch releases the primary control valve. This non-break glass station is provided with a test/reset key. Semi-flush mount on a single gang conduit box. The station is operated by a pull on the cover. This causes a key latch to act agai nst a retaining mechanism until adequate force is applied to open the station. As the station opens, a switch is activated to initiate an electrical signal to the detector circuit in the releasing control panel. The retainer is a permanent high tensile coil spring which is not released when key tested. When operated, the cover hangs down (and cannot be made to stay in a closed position) indicating that the station was used to activate the alarm.

1.3 Fire Detection Devices

1.3.1 Sprinkler Heads

Any closed sprinkler head can be used as a thermal detector whenever hydraulic or pneumatic activation of the primary control valve is desired. Although a large variety of sprinkler temperature ratings exist, ratings between 135°F (57°C) and 212°F (100°C) are most common for use in wet or dry pilot lines. RELIABLE Bulletins 110 and 117 illustrate suitable standard Model G and Model F1 sprinklers, respectively. Model G Sprinklers may be coated with wax or lead for corrosion resistance. Quick response sprinklers installed in wet or dry pilot lines may be desirable as a means for hastening operation of a thermal detection system. Models GFR and F1FR sprinklers are described in RELIABLE Bulletins 131 and 136, respectively. However, these quick response sprinklers cannot be coated for corrosion-resistance. Sprinkler heads used as thermal detectors must be spaced according to NFPA 13 sprinkler spacing requirements. The sprinklers on the pilot lines must be spaced the same as the sprinkler spacing required for the Hazard to be protected. Refer to RELIABLE Bulletins 501 and 503, and to the Hydraulic Data (section 4.1) for detailed information on pilot line elevation and length limitations.

1.3.2 Thermal Detectors:

1.3.2.1 Fixed Temperature Type with Rate Anticipation

A Model 302 detector operates within a controlled range of two to three degrees of its set point, regardless of the rate of temperature rise. Under rapid heat conditions, the rate anticipation feature causes the detector to respond one to three degrees ahead of the setting. However, it does not respond to momentary temperature fluctuations below the selected protection level, thus eliminating false alarms. The detector automatically resets itself after an alarm when temperature drops below the protection level. It is hermetically sealed, shock and corrosion resistant, and tamper resistant. An explosion proof version is also available. Electrical Rating: 5 amp @ 6 to 125 VAC 1 amp @ 6 to 25 VDC

During a fire, however, air temperature rises very rap idly, and the air within the air cham ber ex pands faster than it can be vented. The re sulting pressure distends the diaphragm and closes a set of nor mally open con tacts, thereby activating an elec tri cal cir cuit.

When the ambient temperature reaches the rated temperature of the fixed-temperature el ement, it op er ates re gard less of the rate of in crease. The fus ible al loy melts and the heat col lector falls away, providing a visual indication that the detector has operated.

Each detector includes a patented reversible mounting plate. In one position, it attaches easily t o a 4 (102mm) junction box, 3½ (82.6mm) octagon box, or plaster ring. Reverse it, and the plate mounts for open wiring without a junction box.

1.3.4 Flame Detectors

1.3.4.1 Infrared (IR) Type

Infrared radiation is present in most flames. Therefore, an IR detector can detect the presence of fire instantaneously. A relatively long IR wavelength allows it to penetrate smoke, making detection possible. However, sources of IR radiation are not limited to fire. Because there are so many sources of IR in the industry setting, the number of false alarms caused by detection of non-fire-related sources has precluded use of a simple IR sensor as a viable fire detector. To make the ba sic IR de tec tor func tion in the in dus trial en vi ron ment, ad di tional dis criminating functions must be added. A sig nif i cant ad vance ment in IR de tec tion is a de tec tor ca pa ble of sens ing a spe cific and lim ited band of IR radiation in the wavelength range of 4.1 to 4.6 microns. Hydrocarbon fires all produce radiation in this region, known as the "carbon dioxide spike." This IR detector is still subject to false alarm, but to a far lesser extent than previous broadband IR detectors.

1.3.4.2 Ultraviolet (UV) Type

Ultraviolet detectors are not plagued by as many possible sources of false alarms. However, they may not be able to detect a fire because of smoke obscuration, or the UV intensity may be reduced by a buildup of dirt or oil on the lens. Sources of false alarms for UV detectors are well defined. The most common are:

· Lightning

Lightning is the richest source of UV on earth. The electrical arc ionizes a path to the ground or from cloud to cloud and produces enough UV to actuate every detector in the area. However, the lightning strike is limited in duration and can normally be compensated for by a time delay of five or ten seconds. This, however, also limits the speed with which a real fire can be detected. X-Radiation Boroscopic examination of air craft as sem blies in han gars has emit ted enough ra di a tion to ac ti vate UV detectors. Arc welding A rich source of UV, arc welding is used frequently in industry and is undoubtedly the biggest single cause of false alarms in UV fire detection.

28 1.3.4.3 Dual Spectrum (UV-IR) Type

This detection method employs a solar blind UV sensor with a narrow band IR detector. As noted previously, a UV sensor is a good fire detector, but will react to x-rays, lightning, and arc welding. To prevent false alarms caused by these sources, the UV-IR detector utilizes an IR detector sensitive to wavelengths in the 4.1 to 4.6 micron range. In the industrial environment, the predominant sources of false alarms for ultraviolet fire detectors are welding, lightning, electrical arcs, and x-rays. Sunlight, heaters, lamps, and hot equipment have been identified as the predominant sources of false alarms for IR detectors. Since these sources of false alarms are mutually exclusive, logically combining the detected signal for a UV and IR sensor greatly reduces the false alarm rate. OMNIGUARD® 850 Series fire detectors owe their high level of false alarm rejection to a patented circuit known as FEA (Fire Event Analysis). Most dual-spectrum fire detectors use a threshold level measurement to confirm a fire presence. Only the 850 Series uses Fire Event Analysis.

Model 850 Specifications:

Response time: 150 msec typical for saturating fire signal. Self-test: Manual and automatic through-the-lens check.

34 1.4.2.1.2 Pressure Maintenance Devices

Automatic pressure maintenance devices are used to maintain the correct pressure in the dry pilot l ine to connect dry pilot actuators. The devices described below eliminate the need for manual refilling of dry pilot lines to overcome small leaks or temperature changes. RELIABLE Automatic Pressure Maintenance Devices do not interfere with the prompt operation of Model A Dry Pilot Actuator releasing devices. · Model A-2 The Model A-2 Device is designed for use where a source of compressed gas is available, such as a plant wide compressed air system, a tank mounted air compressor with a pressure control switch, or cylinders of compressed gas. In areas where moisture-laden air could cause freezing problems in a dry pilot line, the use of air dryers or cylinders of dry compressed gas, such as nitrogen, is suggested. Approved gas handling regulators and connections are required on these cylinders. For nitrogen regulators see Bulletin 253. The regulator in the Model A-2 Device will reduce the pressure from an acceptable gas source (175 psi (12 bar) maximum) to the level required in a dry pilot line. The Model A-2 Device will maintain a constant pressure in the pilot line, regardless of fluctuations in the higher pressure compressed gas source being used. The strainer prevents any foreign matter in the air from traveling to the regulator and check valve and interfering with their normal operation. The shut-off valves permit the servicing of the strainer and regulator without shutting down the sprinkler system. The bypass valve permits rapid restoration of the required system pressure after service or operation. The bypass valve must be closed and shut-off valves open for proper automatic operation. Refer to Bulletins 250 and 251 for more information.

· Model B-1 The Model B-1 Device is designed for use in conjunction with a tankless compressor which does not have a pressure control switch to maintain the correct pressure in a dry pilot line. By wiring the compressor motor to the adjustable electrical pressure switch of the Model B-1 Device, the operati on of the compressor is controlled by the desired pressure in the dry pilot line.

A significant decrease in air pressure closes the pressure switch activating the compressor. When the air pressure is restored to the pre-adjusted setting, the pressure switch opens, stopping the compressor. The pressure switch is equipped with an unloader valve which automatically bleeds off the compressor outlet pressure (through the copper tubing) each time the pressure switch opens. This protects the compressor motor from overload at the next start-up. Like the Model A-2 Device, the Model B-1 has a strainer for contamination control, and the bypass valve must be closed and the shut-off valves open for proper automatic operation. Refer to Bulletins 250 and 251 for more information.

36 1.4.2.2 Supervisory Pressure 1 to 2 psi (0,14 bar)

Supervisory pressure maintenance equipment provides low pressure (approx. 30 oz/in2) compressed gas to the sprinkler piping of a preaction system. Leakage, such as that caused by damage to the piping or sprinklers, can cause the supervisory pressure to decrease. When pressure falls below approximately 11 oz/in2 (0,05 bar), either a horn is sounded (Model B & C Air Compressor Panel), or a switch operated (Model C Pressure Maintenance Device). The switch must be connected to a separate trouble annunciator.

1.4.2.2.1 Air Compressor Panel-- For Single-Interlock Preaction Systems

Model B (120 VAC) and C (220 VAC) Air Compressor Panels are a completely self-contained supervisory air supply. The panel is supplied with an externally connected assembly consisting of a check valve, copper tubing, and tubing connector. The ¼ NPT check valve must be installed at the sprinkler riser with its flow arrow pointing toward the riser. Install the check valve above the priming water level. The copper tubing connects the inlet of the check valve to the air compressor panel air outlet.

The Model C Device reduces 40 to 100 psi (2,8 to 6,9 bar) supply pressures to approximately 30 oz/in2 (0,13 bar) outlet pressure. A separate trouble annunciator must be connected to the low pressure switch. This switch is factory set to transfer dry contacts, when the supervisory pressure falls below approximately 11oz/in2 (0,05 bar). Refer to Bulletin 252. Combining the Model C Pressure Maintenance Device with the tank mounted air compressor, shown on page 33, will provide an efficient 2 psi (0,1 bar) supervisory air supply for preaction systems.

1.4.2.3 Supervisory Pressure - 20 to 50 psi (1,4 to 3,5 bar)

Supervisory pressure maintenance equipment may be required to provide pressures above 20 psi (1,4 bar), but not to exceed 50 psi (3,5 bar). Usually, when this type of application exists, the pressure has a dual purpose of supervising the leak-tightness of the sprinkler piping and maintaining a pneumatic releasing device (ref. Section 1.2.2) in the closed position. Whenever supervisory pressures must be at a level somewhere between 20 and 50 psi (1,4 and 3,5 bar), use either the Model A-2 or Model B-1 pressure maintenance device (described in Section 1.4.2.1.2). Some preaction systems (e.g. Type D Double-Interlock) are designed to employ 10 psi of supervisory pressure. The Model A-2 Pressure Maintenance device is used for these applications.

1.4.3 Alarm Devices

1.4.3.1 Mechanical (Water Motor) Bell

The Model C Mechanical Alarm, also called a water motor and gong, is a hydro- mechanical alarm usually mounted on an outside building wall and energized by water flowing from special porting in a primary control valve. When a control valve is operated by the fusing of one or more automatic sprinklers, water flows through the ¾ strainer and ¾ piping that connects to the water motor. In the motor, water passes through the nozzle and impinges against the Pelton wheel blades causing the Pelton wheel to rotate. The striker assembly connected to the Pelton wheel by the drive shaft also rotates causing the striker to impact against the gong producing a continuous piercing alarm. The water, after impinging against the Pelton wheel, drains off through the 1 drain outlet in the body motor. The alarm continues to sound as long as water is in the sprinkler system. The water motor alarm may be shut off by closing the alarm control valve, located in the trim of the primary control valve. Model C Mechanical Alarms are self resetting after each operation, eliminating the need of removing cover plates, etc. to reset internal mechanisms. Refer to Bulletins 612 and 613 for more information. Listed by Underwriters Laboratories, Inc & Underwriters' Laboratories of Canada. Approved by Factory Mutual Research Corporation & Loss Prevention Council. NYC BS & A No. 587-75-SA.

1.4.4 Pressure Activated Switches

Pressure activated switches are used to control the operation of fire alarm devices, trouble annunciating devices, and electrical equipment (such as, computer systems and HVAC systems) when water flows from a primary control valve into a sprinkler system. Pressure switches are also used for supervising the intended maximum or minimum pressure limits in sprinkler systems and pilot sensing lines.

1.4.4.1 Alarm Type

System Sensor EPS10 Series Switches are designed for use in wet, dry, deluge and preaction automatic sprinkler systems to indicate a discharge from a sprinkler. Model EPS10-1 has a single SPDT switch while Model EPS10-2 contains two SPDT switches. The EPS-10 Series features field adjustable pressure sensitivity to provide alarm response between 4 and 20 psi (0,3 and 1,4 bar). It is factory set to respond at 4 (0,3) -8 psi (0,3 - 0,55 bar) on rising pressure. The pressure adjustment wheel requires no special tools and does not affect switch synchronization on the EPS10-2.

1.4.4.2 Supervisory Type

The System Sensor EPS40 switches are designed to detect a 10 psi (0,7 bar) decrease from normal system pressure in automatic fire protection systems. They are typically used to supervise system air pressure in dry pipe systems or pressure tanks and water pressure supplies of automatic water control valves. These switches can be used to initiate electronic signals or to start/shut down auxiliary fire equipment when a low pressure condition occurs. The EPS40-1 Series features field adjustable pressure sensitivity between 10 and 100 psi (0,7 and 6,9 bar). It is factory set to be used in a nominal 40 psi (2,8 bar) system with a switch transfer occurring at 30 psi (2 bar). The pressure adjustment wheel requires no special tools and can be used to adjust the point at which the low switch activates. The EPS40-2 features field adjustable pressure sensitivity between 10 and 100 psi (0,7 and 6,9 bar). It is factory set to be used in a nominal 40 psi (2,8 bar) system with a switch transfer occurring at 30 psi (2 bar) and a second switch transfer occurring at 50 psi (3,5 bar). The pressure adjustment wheel requires no special tools and can be used to adjust the nominal value of the "window" at which the low and high switches activate.
