ENGINEERING SPECIFICATIONS
Smoke detector shall be an ionization type (Model 1400)
as manufactured by System Sensor. Wiring connections
shall be made by means of SEMS screws. Detector will
have a visible LED which will blink in standby and latch on
in alarm. The detector shall have a sensitivity of 1.9 ±
0.6%/ft. as measured in the UL smoke box. The detector
screen and cover should be easily removable for clean-
ing. It shall be possible to perform a sensitivity and func-
tional test on the detector without the need of generating
smoke. The detector shall have a mounting bracket that
allows for mounting to a 3-1/2" (8.89 cm) or 4" (10.16 cm)
octagonal box or a 4" (10.16) square electrical box.
