connections. No solder connections will be allowed. Detectors located in
concealed locations (above ceiling, raised floors, etc.) shall have a
remote visible indicator LED/LCD. Addressable fire detecting devices,
except flame detectors, shall be dynamically supervised and uniquely
identified in the control panel. All fire alarm initiating devices shall
be individually addressable, except where indicated. Installed devices
shall conform to NFPA 70 hazard classification of the area where devices
are to be installed.
2.5.1
Heat Detectors
Heat detectors shall be designed for detection of fire by [fixed
temperature] [combination fixed temperature and rate-of-rise principle]
[rate-compensating principle]. Heat detector spacing shall be rated in
accordance with UL 521. Detectors located in areas subject to moisture,
exterior atmospheric conditions, or hazardous locations [as defined by NFPA
70] [and] [as shown on drawings], shall be types approved for such
locations. Heat detectors located in attic spaces or similar concealed
spaces below the roof shall be intermediate temperature rated.
2.5.1.1
Combination Fixed-Temperature and Rate-of-Rise Detectors
Detectors shall be designed for [surface] [semi-flush] outlet box mounting
and supported independently of wiring connections. Contacts shall be
self-resetting after response to rate-of-rise principle. Under fixed
temperature actuation, the detector shall have a permanent external
indication which is readily visible. Detector units located in boiler
rooms, showers, or other areas subject to abnormal temperature changes
shall operate on fixed temperature principle only. The UL 521 test rating
for the fixed temperature portion shall be [[57.2] [_____] degrees C [135]
[_____] degrees F] [as shown]. The UL 521 test rating for the Rate-of-Rise
detectors shall be rated for 15 by 15 m 50 by 50 ft.
2.5.1.2
Rate Compensating Detectors
Detectors shall be [surface] [flush] mounted [vertical] [horizontal] type,
with outlet box supported independently of wiring connections. Detectors
shall be hermetically sealed and automatically resetting. Rate Compensated
detectors shall be rated for 15 by 15 m 50 by 50 ft.
2.5.1.3
Fixed Temperature Detectors
Detectors shall be designed for [surface] [semi-flush] outlet box mounting
and supported independently of wiring connections. Detectors shall be
designed to detect high heat. The detectors shall have a specific
temperature setting of [[57.2] [_____] degrees C [135] [_____] degrees F]
[as shown]. The UL 521 test rating for the fixed temperature detectors
shall be rated for 4.57 by 4.57 m 15 by 15 ft.
2.5.2
Smoke Detectors
**************************************************************************
NOTE: Choose the type of smoke detector most suited
for application or design.
**************************************************************************
Smoke detectors shall be designed for detection of abnormal smoke
densities. Smoke detectors shall be [ionization] [photoelectric] [or]
[projected beam] type. Detectors shall contain a visible indicator LED/LCD
