Engineering Specifications
Smoke Detector shall be a photoelectronic type (model
2400, 2412, 2424) or a combination photoelectronic/
thermal (model 2400TH, 2412TH, 2424TH) with thermal
sensor rated at 135°F as manufactured by System Sensor.
Wiring connections shall be made by means of SEMS
screws. The detector will have a visible LED which will
blink in standby and latch on in alarm. The detector shall
have a nominal sensitivity of 3% per foot as measured in
the UL smoke box. The detector screen and cover should
be easily removable for cleaning. It shall be possible to
perform a sensitivity and functional test without the need
of generating smoke. Detector circuitry shall perform a self
test on the sensing chamber and internal electronics every
40 seconds. If circuitry fails, the detector LED shall stop
blinking. The detector shall have a mounting bracket that
allows for mounting to a 31/
square electrical box.
