Alarm Active Mode
This mode indicates that one or more gas concentrations have achieved unsafe
levels. In this mode the Power indicator will be lit. In the case that the CO
concentration is unsafe the Carbon Monoxide indicator will be lit. In the case that
the LP concentration is unsafe the Propane indicator will be lit. In this mode the
audible indicator will signal an alarm, and the Reset function of the Test/Reset
button will be active. This mode will be exited automatically if the CO concentration
falls to a safe level for an extended period of time and LP concentrations falls below
500 ppm for greater than 10 seconds.
Alarm Test Mode
This mode indicates that the Test function of the Test/Reset button was imitated. In
this mode, all visual indicators will be lit, and the audible indicator will signal an
alarm. The test/Rest button will not function during this mode. This mode will be
exited automatically within 10 seconds.
Alarm Reset / Stabilization Mode
This mode indicates that the alarm is stabilizing for the first 3 minutes after power-
up or the first 6 minutes after the Rest Function was initiated. In this mode the
Power indicator will be lit, and the reset alarm's indicator will be flashing. The other
visual indicators, the audible indicator, and the Test/Reset button function will be
off. This mode will be exited if the previously inactive alarm is triggered. If gas
concentrations are still high after the 6 minutes, the previous alarm will reactivate.
Fault Mode
This mode indicates that a fault has been detected that compromises some alarm
function. If a fault is detected on only one of the sensors, the other sensor would
function normally. The table below lists the indicator actions and the corresponding
alarm status. This mode will be exited automatically when the fault is cleared.
If the fault persists, the alarm is not functioning properly and must be replaced to
ensure your safety in the area.
