The Latching Alarm Indicator is activated after a
CO Alarm is exposed to alarm levels of carbon
monoxide. After CO levels drop below alarm levels,
the red LED will begin to flash once every 5 seconds.
It will continue to flash or “latch” until you clear it by
pressing the test button.
This feature helps emergency responders, investiga-
tors, or service technicians identify which unit(s) in
your home were exposed to alarm levels of carbon
monoxide. This can help investigators pinpoint the
source of CO.
Interconnected Alarms
Latching Alarm Indicator shows which Alarm(s) in
the series were exposed to alarm levels of carbon
monoxide.
The Latching Alarm Indicator stays ON until you clear
it, so it can alert you to a CO Alarm that occurred
while you were away from home, even though CO
present in the air has dropped below alarm levels.
