NOTE: American Disabilities Act (ADA) requires that
manual alarm stations be mounted at a maximum of 1.2
m (48 inches) above finished floor (AFF) for forward
reach and 1.4 m (54 inches) AFF for side reach.
**************************************************************************
Manual fire alarm stations shall conform to the applicable requirements of
UL 38. Manual stations shall be connected into signal line circuits.
Stations shall be installed on [surface] [semi-flush] [flush] mounted
outlet boxes. Manual stations shall be mounted at [1220] [1370] [_____] mm
[48] [54] [_____] inches. Stations shall be [single] [double] action type.
Stations shall be finished in red, with raised letter operating
instructions of contrasting color. Stations requiring the breaking of
glass or plastic panels for operation are not acceptable. Stations
employing glass rods [are] [are not] acceptable. The use of a key or
wrench shall be required to reset the station. Gravity or mercury switches
are not acceptable. Switches and contacts shall be rated for the voltage
and current upon which they operate. Stations shall have a separate screw
terminal for each conductor. Surface mounted boxes shall be matched and
painted the same color as the [fire alarm manual stations] [mounting
surface].

FIRE DETECTING DEVICES
**************************************************************************
NOTE: Remove last sentence when not applicable.
**************************************************************************
Fire detecting devices shall comply with the applicable requirements of
NFPA 72, NFPA 90A, UL 268, UL 268A, and UL 521. The detectors shall be
provided as indicated. Detector base shall have screw terminals for making
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. Installed devices shall conform to the
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.
