Alarm (max.) 120 A * * 120 A 77mA 120 A 120 A 77mA 120 A 41mA 41mA 120 A 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 31/2 or 4 octagon box or 4 square electrical box.
