transmitter sends an alarm signal to the supervised receiver.
The alarm signal is repeated every
10
seconds thereafter if
smoke or CO is still present. A restore report is sent when the
smoke/CO detection chamber clears. Smoke and CO super-
visory status reports are sent from the unit every hour. Each

INFORMATION ABOUT CARBON MONOXIDE
Carbon monoxide, also known as "CO", is a highly dangerous
poisonous gas because it is colorless, odorless, tasteless, and
very toxic. The presence of CO gas inhibits the blood's ability
to transport oxygen throughout the body, eventually leading to
brain damage. In any enclosed space (home, office, recrea-
tional vehicle or boat) even a small accumulation of CO gas
can be dangerous. Although many products of combustion

E
is a high
-
quality combination photoe-
lectric smoke detector (conforms to UL 268) and carbon mon-
oxide detector (conforms to UL 2075) and is equipped with a
supervised digitally coded radio transmitter. It is compatible
with NAPCO's GEM
-
RECV and GEMC
-
RECV series super-
vised receivers that monitor alarms, restores, low battery, tam-
per, and status; for use with NAPCO's GEM and GEMC se-
ries Control Units.
Note:
See Control Unit installation instruc-
tions for compatibility.
During normal operation, the green LED on the
