The GEM-SMK is a high-quality photoelectric smoke detector with a built-in supervised digitally-coded radio transmitter. It is compatible with NAPCOS GEM-RECV Series supervised security receivers that monitor alarms, low battery and status.
The GEM-SMK sounds a local alarm as soon as smoke is detected and the transmitter will send an alarm signal to the supervised receiver. The alarm signal will be repeated every 10 seconds thereafter as long as smoke is still present. A restore report will be sent when the smoke-detection chamber clears. Supervisory status reports are sent from the GEM-SMK every hour.
