The Learn Mode
Carbon Monoxide (CO) alarm detects hazardous levels of CO gas. If a dan-
gerous concentration of gas is detected, a red indicator light turns on and an internal siren is acti-
vated. The CO alarm also transmits an alarm signal to the control panel within 15 seconds of
detecting CO gas (see Figure 1). The control panel activates its own sirens and reports the alarm
to the central monitoring station (if the system is monitored).
The indicator lights on the CO alarm react to the status of their environment.
A green light indicates an ON or normal condition. The CO alarm has power and is sampling air
for CO gas.
A red light indicates an ALARM condition and that the CO alarm is currently sensing hazardous
CO levels. All persons and animals must evacuate immediately and the area should be venti-
The internal siren activates when hazardous CO levels are present. The siren may be silenced for
seven to nine minutes by pressing the RESET button.
If the reset button is pressed within 15 seconds of the initial alarm, the CO detector
will not transmit an alarm signal to the control panel.
