on a high rate of charge as part of the unit assembly if a high-rate switch is provided.
2.4 MANUAL ACTUATION STATIONS
NOTE: Where there is no room flooding or no raised floor space, omit requirement
for separate actuation stations.
Provide actuation stations for systems at the exits from the protected areas. Operation of a manual station
shall cause the control panel to go into full alarm condition and discharge Halon into the protected area following
the adjustable time delay. [Provide separate, clearly labelled, manual stations for control of underfloor discharge
and room flooding.] Stations shall be of a type not subject to operation by jarring or vibration. Stations shall
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 shall be red or orange.
Warning signs shall be placed at each station indicating that operation of the station will cause immediate Halon
discharge. Where building fire alarm pull stations are also mounted at the exits from the protected areas, they
shall be separated from Halon actuation stations by at least one meter 3 feet horizontally, labels shall be provided
to clearly distinguish building fire alarm stations from Halon stations and stations shall be of different colors.
2.5 SMOKE DETECTORS

control and/or power modules required for operation of the device shall be integral with the main control panel.
Detectors shall be compatible with main control panel provided and shall be suitable for use in a supervised
circuit. Detectors shall not draw power from the initiating circuit. Operating power shall be taken from a
separate supervised power supply circuit. Malfunction of the electrical circuitry to the detector or its control
or power units shall result in the operation of the system trouble devices. Detectors shall not be susceptible
to operation by changes in relative humidity. Each detector shall contain a visible indicator lamp that shall
show when the unit is activated. Each detector shall be the plug-in type in which the detector base contains
screw terminals for making all wiring connections. Remote indicator lamp shall be provided for each detector

raised floors shall not exceed 23.25 square meter 250 square feet per detector. Detectors installed beneath
raised floors shall be mounted with the detector base within 50 mm 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 305 mm 12 inches
in height, detectors shall be mounted with their bases either horizontal or vertical, with the detection chambers
mounted in the upper half of the underfloor space. Under no circumstances shall detectors be mounted facing
upward.
[2.6 DUCT SMOKE DETECTORS
NOTE: Automatic dampers are required in all ducts passing through walls, floors,
and ceilings, to prevent the leakage of Halon from the protected space, and
to prevent the communication of fire and smoke. Locations of dampers should
be shown on HVAC plans. Additional smoke dampers may be required in systems
over 424,740 L/m 15,000 cfm by NFPA 90A, Air Conditioning and Ventilating Systems
. Coordinate with Section 23 09 53.00 20, SPACE TEMPERATURE CONTROL SYSTEMS.

to Halon system control panel only if no building fire alarm system is provided.
Otherwise delete paragraph entitled "Duct Smoke Detectors."
In accordance with the requirements of NFPA 90A, the manufacturer's recommendations and the requirements stated
herein. Detectors required in ducts shall be ionization type and listed by UL Fire Prot Dir or FM P7825for duct
installation. Provide duct detectors with an approved duct housing, mounted exterior to the duct, with perforated
sampling tubes extending across the width of the duct. Activation of duct detectors shall cause shut down of

a rigid plastic or metal identification sign with lettering a minimum of 40 mm 1.5 inches high. The pre-discharge
alarm shall be labelled "FIRE" and the discharge alarm shall be labelled "HALON DISCHARGE." [Post-discharge visual
alarms shall be located outside all entrances to the protected areas, and shall be provided with signs reading
"HALON DISCHARGED WHEN FLASHING - DO NOT ENTER].
