120VAC 60 Hz 0.09A
FEATURES
This CO Alarm is designed to be hard-wired and
mounted on any standard size junction box, up to 4”
size. 120V AC power to the junction box must not be
controlled by a dimmer or switch (other than a circuit
breaker.)
This CO Alarm samples the air and takes a new read-
ing about every second. A microchip inside the unit
stores each reading, and remembers the levels of CO
it has been exposed to over time. The unit goes into
alarm mode when it has been exposed to a “critical”
level of CO (measured in parts per million or “ppm”)
within a specified time (measured in minutes).
General features: This Alarm features a permanently
installed sensor, a red indicator light (LED), and an
85 dB alarm horn.
9V Battery Back-Up. If AC power is interrupted,
the CO Alarm will continue to operate for a short
time, provided the 9V battery is fresh and correctly
installed.
Silence Feature. The Silence feature temporarily
quiets the alarm.
Low Battery Silence Feature. Temporarily silences
the Low Battery Warning “chirp” for up to 8 hours if
AC power is present.
Digital Display. Shows levels of CO, measured in
parts per million present and any stored peak levels.
Malfunction Warning. This unit performs
self-diagnostic tests approximately every second.
If the alarm malfunctions, it should be replaced
immediately.
