NAPCO GEM-SMK User Manual

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 pre-
sent. A restore report will be sent when the smoke detec-
tion 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.

unit for up to two years. If the battery voltage drops be-
low normal, a low-battery report will be sent to the re-
ceiver with any status or alarm transmission. If a low-
battery condition is indicated, replace both batteries.
