Description
The GEM-SMK is a high-quality photoelectric smoke detector with built-in supervised digitally-coded radio transmitter. It is compatible with Napco's GEM-RECV Series supervised security receivers that monitor alarms, restores, low battery and status.
During normal operation, the LED on the GEM-SMK flashes once every 30 seconds. As soon as smoke is detected, the GEM-SMK sounds a local alarm and the transmitter sends an alarm signal to the supervised receiver. The alarm signal is repeated every 10 seconds thereafter as long as smoke is still present. A restore report is sent when the smoke detection chamber clears. Supervisory status reports are sent from the GEM-SMK every hour.
Coding switches are not required or used in the GEM-SMK. Each transmitter is assigned a unique identification code number at the factory.
