Alarm Memory
The Alarm memory records when the alarm has been triggered, warning the occupier that
CO gas has been detected even if no one is in the house at the time.
The memory feature has two operation modes:
- memory indication for 24 hour period after alarm.
- memory recall on demand
24 hour memory indicators: After alarm, the red LED will flash at different rates every
minute (approx) depending on the level of CO detected - see Table C.
Memory recall on demand: To review the memory status after initial 24 hours, press and
hold the test button, the red LED will flash in accordance to Table C. Display models will
show the peak level of CO measured.
Reset Memory: Hold down the test button until the red LED stops and the green LED starts
flashing. Cover the horn with a cloth to muffle the alarm during this time. Please note that
the memory will also be reset when the CO Alarm is switched off.
