2.2 SYSTEM COMPONENTS:

1. Pre-action control panel.

2. Battery charger.

3. Batteries.

4. Valve trim box.

5. Supervised system shutoff valve.

6. Flow control valve and trim.

20.Waterflow pressure switches.

21.Valve supervisory switches.

22.Piping.

23.Sprinkler heads. 2.3 SYSTEM OPERATION:

A. Automatic Operation:

1. When a fire occurs, a detector is heated to its trip point. The normally closed detector circuit then opens. The relays in the control panel open, shutting off power to the solenoid valves in the trim box and sounding the electric fire alarm bell. When the solenoid valves open, the pressurized water in the top chamber of the flow control is released and the clapper opens. The system then fills almost completely with pressurized water. When the sprinkler head reaches the operating temperature, it opens and sprays water on the fire. When the temperature in the fire area drops below the trip point of all detectors, the detector circuit is closed. A relay is closed in the panel which energizes the timer. Water will continue to discharge from the open sprinklers from one to 5 minutes, depending on the timer setting. When the timer cycle is complete, a relay in the control panel closes and energizes the solenoid valves in the trim box. The flow of water stops from above the clapper of the flow control valve thereby causing a pressure to build up which closes the valve clapper and stops the flow of water to the opened sprinklers. The electric fire alarm will continue to sound until the reset button is pushed.

AE Project Number: Revision Date: July 28, 2017

Pre-Action Sprinkler Systems, Fire

21 13 18 – 6

2. Should the temperature build to the trip point of any detector during any phase of the cycle, the system will continue to flow or immediately start the flow of water to the fire.

B. Operation as a Dry System: Loss of air pressure operation shall be key-switch activated at the control panel. When a fire occurs and the temperature reaches the operating point of a sprinkler, the system's pressurized air escapes through the open sprinkler. When the pressure has dropped to approximately 12 psi (80 kPa), a pressure switch in the trim box opens a relay in the control panel causing the low air pressure alarm to sound. When the air pressure drops to approximately 7 psi (50 kPa), another pressure switch in the trim box opens causing a second relay to open in the control panel de energizing the solenoid valves in the trim box and sounding the electric fire alarm. When the solenoid valves open the pressurized water in the top chamber of the flow control valve is released and the clapper opens. The system then fills with pressurized water which sprays from the sprinkler and sounds the water motor alarm, if provided. The waterflow is stopped by closing the main control valve. The system will not recycle when used as a standard dry-pipe system.

2.4 PRE-ACTION CONTROL PANEL:

A. The control panel shall incorporate all necessary relays, timers, switches, alarms, and trouble lights

necessary for system operation. The panel shall be factory-prewired.

B. The control panel shall be flush-mounted in the location shown on the Drawings.

C. All valves which control the flow of water from the standpipe to the pre-action system shall be supervised via tamper switches monitored by the control panel.

D. A battery charger and sealed battery suitable for operation of the system for 90 hours shall be provided. The battery and charger cabinets shall be installed in the floor air handling unit room.

E. The control panel is connected to the normally closed fire detector circuit, valve trim box, power supply and electrical alarms.

1. When a fire detector operates, the following sequence occurs:

a. Power is shut off to the solenoid valves in the valve trim box and the electric alarm operates.

b. The solenoid valves open and vent the upper chamber of the flow control valve allowing it to open and supply water to the sprinkler system piping.

2. When all fire detectors reset:

a. The timer is energized allowing water flow to continue for a predetermined time period from one minute to 5 minutes.

b. At the end of that time the solenoid valves in the valve trim box are energized and shut of the flow of water from the top chamber off the flow control valve which in turn closes the flow control valve and stops the flow of water to the sprinkler system piping.

F. A key-operated control, located on the side of the control panel, allows the system to be operated as a cycling pre-action system with the electrical detection circuit in service or as a dry system without the electrical detection circuit in service. (NO RECYCLING OF THE SYSTEM WILL OCCUR WHEN IT IS OPERATING AS A DRY SYSTEM). The control panel shall incorporate a system tripped light and a low air pressure light. System operation or low air pressure shall activate the audible trouble alarm and optional other alarms. These can be silenced by on/off switches. The key-operated thermal test button acts to open the detector circuit momentarily to cycle the system. The reset button resets timer and alarm circuits after system operation. The system may be operated as a wet-pipe sprinkler system if the detector circuit and/or pressurized air are unavailable for service; however, all alarms except the low air pressure alarm will operate constantly unless shut off and cycling features are negated.

G. A normally open, dry contact rated at 120 volts, 10 amperes shall be provided in the preaction control panel and shall close upon system charging to shunt trip circuit breakers serving elevator [computer] equipment.

2.5 PRE-ACTION VALVE TRIM BOX:

Page 39: University of Houston Master Construction Specifications ... · University of Houston Master Construction Specifications Insert Project Name . Fire Protection Systems 21 12 00 –

University of Houston Master Construction Specifications Insert Project Name

AE Project Number: Revision Date: July 28, 2017

Pre-Action Sprinkler Systems, Fire

21 13 18 – 7

A. The valve trim box shall incorporate all solenoid valves, pressure switches, terminal blocks and accessories necessary for operation of the System. The valve trim box shall be factory pre-wired and pre-piped.

B. The components of the valve trim box are operated through relays in the control panel (see Control Panel Data Page). The solenoid valves (referred to on the wiring diagram as V1 and V2) control the flow of water from the top chamber of the flow control valve. When the normally closed solenoid valves are opened, pressurized water trapped in the top chamber of the control valve escapes, allowing the control valve clapper to rise and pressurized water to fill the sprinkler system piping. When the solenoid valves are electrically closed, the flow of water from the top chamber of the control valve is stopped. Water pressure builds in the top chamber which forces the clapper to shut off the flow of water to the sprinkler system. The pressure switch, PS#2, controls the low air pressure alarm bell. If the sprinkler system air pressure drops below 12 psi (83 kPa), an alarm will sound. The pressure switch, PS#1, controls waterflow to the sprinkler system when the selection switch is turned to the OFF position and the system is being operated on loss of air pressure. If the pressurized air in the piping system drops below 7 psi (48 kPa), the solenoid valves will be de-energized and pressurized water will flow to the sprinkler system.

2.6 HEAT DETECTORS:

A. Detectors shall be heat sensitive, electrical detectors which operate at a fixed temperature of 140°F.

Detectors shall be rate compensating and feature automatic recycling. Detectors shall be connected in series from and to the control panel. When a detector is heated to the temperature set point, a mechanical switch shall open and break the series circuit interrupting the flow of current..

B. Detectors shall be located on maximum [20'x 20'] [Reduce smoke detector spacing for rooms or areas utilizing high air flow as required per NFPA 72] centers and shall be coordinated with locations of light fixtures, grills, speakers, smoke detectors and other ceiling mounted devices.

C. Detectors in finished ceiling areas shall be installed using through ceiling mounting. 2.7 DETECTOR CABLE:

A. Detector cable shall consist of two number 16 conductors surrounded by a high temperature insulation

encased in an aluminum sheath. 2.8 FLOW CONTROL VALVE AND TRIM:

provided. 2.9 AIR MAINTENANCE DEVICE:

A. An air maintenance device shall be provided to supply each pre-action zone. The air maintenance
