Description.
Description. The GEM-SMK is a high-quality photoelec-
tric 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.
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 cham-
ber 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.
The smoke detector and transmitter are powered by two
9-volt alkaline batteries (supplied) which can power the unit
for up to two years. If the battery voltage drops below
normal, a low-battery report will be sent to the receiver with
any status or alarm transmission. If a low-battery condition
is indicated, replace
both
batteries. Note:
Note: Temperature and
humidity extremes may reduce the life of the battery.
