Provide actuation stations for systems at the exits from the protected areas. Ensure manual station operation causes the control panel to go into full alarm condition and discharge Clean Agent into the protected area following the adjustable time delay. Install stations of a type not subject to operation by jarring or vibration. Ensure stations have a dual action release configuration to prevent accidental system discharge.

Break-glass-front stations are not permitted; however a pull lever break-glass-rod type is acceptable. Station color is yellow or orange.

Place warning signs, "Agent Trade Name" manual release, at each station indicating that operation of the station initiates immediate Fire Suppression Agent discharge.

Provide labels to clearly distinguish building fire alarm stations from Fire Suppression Agent stations. Ensure Fire Suppression Agent stations are a different color from building fire alarm pull stations.

2.3.6 Smoke Detectors

Design for detection of abnormal smoke densities by the photoelectric principle. Necessary control and power modules required for operation of the device is integral with the main control panel. Ensure detectors are compatible with the main control panel provided and are suitable for use in a supervised circuit. Ensure detectors do not draw power from the initiating circuit. Take operating power from a separate supervised power supply circuit. Ensure that malfunction of the electrical circuitry to the detector or its control or power units results in the operation of the system trouble devices. Ensure detectors are not susceptible to operation by changes in relative humidity. Each detector contains a visible indicator lamp to show when the unit is activated. Use plug-in type detectors in which the detector base contains screw terminals for making all wiring connections. Provide remote indicator lamps for each detector that is located above suspended ceilings, beneath raised floors or otherwise concealed from view.

2.3.6.1 Photoelectric Detectors

Operate on a multiple cell concept using a light-emitting diode (LED) light source. Failure of the LED does not cause an alarm condition but operates the detector trouble indicating lamp.

2.3.6.2 Detector Spacing and Location

Spacing and location of detectors takes into account the airflow into the room and supply diffusers. Do not place detectors closer than 5 feet from any discharge grille. Spacing of detectors on room ceilings is not to exceed 450 square feet per detector. Spacing of detectors under raised floors is not to exceed250 square feet per detector. Mount detectors installed beneath raised floors with the detector base within 2 inches of the underside of the raised floor framing, with the detector facing downward. Where the space under the raised floor is less than 12 inches in height, mount detectors with their bases either horizontal or vertical, with the detection chambers mounted in the upper half of the underfloor space. Under no circumstances, mount detectors facing upward.

2.3.7 Inhibit Switch

Provide one switch where activation of switch is to delay only equipment shutdown and agent discharge. Switch is guarded, spring-loaded type which operates only when pressure is manually applied to the switch. Upon release of manual pressure, switch de-activates allowing delayed functions to resume. After start of agent discharge, switch has no effect.

Activation of switch during normal (non-alarm) conditions causes activation of system trouble signals.

2.3.8 Alarm Signaling Devices

Provide each protected area with audible and visual alarms located where shown. Electrically supervise all alarm circuits. Provide separate and distinct audible and visual pre-discharge and discharge signals. Where the building is equipped with a separate fire evacuation alarm system, ensure the discharge signals is distinct from those used by the building fire evacuation system. Provide each signal device with a rigid plastic or metal identification sign with lettering a minimum of 1.5-inches high.

Label the pre-discharge alarm "FIRE" and the discharge alarm "Fire Suppression Agent DISCHARGE." Locate post-discharge visual alarms outside all entrances to the protected areas, and provided with signs reading "Fire Suppression Agent DISCHARGED WHEN FLASHING - DO NOT ENTER.

Provide 10 inch surface mounted alarm bells with matching mounting back box. Install bells of the vibrating type suitable for use in an electrically supervised circuit. Install bells of the underdome type that have a sound output rating of at least 90 decibels at 10 feet.

b. Alarm horns

Provide surface mounted, vibrating type alarm horns suitable for use in an electrically supervised circuit that have a sound output rating of at least 90 decibels at 10 feet.

2.3.8.2 Visual Alarms

Surface mounted lamp assembly suitable for use in an electrically supervised circuit. Provide flashing rotary beacon type lamps, powered from the control panel alarm circuit. Provide lamps with a minimum of 50 candle power with a flash rate is between 60 and 120 flashes per minute.

Protect lamps by a thermo-plastic lens, red for pre-discharge alarms and blue for discharge and post-discharge alarms. Visual alarms may be part of an audio-visual alarm assembly.

2.3.9 Main Annunciator

Annunciator is integral with the main control panel. Provide separate alarm and trouble lamps for each zone alarm initiating circuit located on the exterior of the cabinet door or visible through the cabinet door.

Supervision is not required provided that a fault in the annunciator circuits results only in loss of annunciation and does not affect the normal functional operation of the remainder of the system. Ensure each lamp provides specific identification of the device by means of a permanent label. Do not use generic nondescript wording such as "Zone 1," or "Zone 2," for the label identifications.

2.3.9.1 Annunciator Panels

a. Remote Annunciator Panels

Locate as shown. Ensure panel duplicates all requirements specified for the main control panel annunciator, except that in lieu of individual zone trouble lamps a single common system trouble lamp may be provided. Provide a panel lamp test switch. Provide zone identification by means of permanently attached rigid plastic or metal plate(s). Provide interior type, surface panel.

2.4 ACCESSORIES

Provide secondary DC power supply for operation of system in the event of failure of the AC supply. Ensure transfer from normal to emergency power or restoration from emergency to normal power is fully automatic and does not cause transmission of a false alarm. Obtain AC operating power to control panel and battery charger from the line side of the incoming building power source ahead of all building services. Provide independent properly fused safety switch, with provisions for locking the cover and operating handle in the "POWER ON" position for these connections and locate adjacent to the main distribution panel.
