CO Advice

Identify recent CO incidents with Alarm Memory

Be alerted to a recent carbon monoxide alarm activation with this memory feature, available in FireAngel’s new range of CO alarms.

The Alarm Memory feature, available in our new range of FireAngel carbon monoxide (CO) alarms, provides a visual indication of a recent CO incident.

A red LED will flash on the alarm to inform there has been a previous CO alarm activation within the past 30 days. However, if an alarm activation has been silenced, alarm memory will not be instigated immediately.

This new feature is particularly useful for new property leases or if tenants return from a prolonged period away from their home, for example a holiday or hospital stay. By spotting the flashing LED, it provides vital time to ventilate a property and organise an appliance service.

If the device is not silenced during an alarm, it will continue to sound until the CO level has reduced to below 50ppm. Once below this level, the device will flash the red warning light twice every 20 seconds to indicate that dangerous CO levels have been detected in a resident’s absence. The red warning light will continue to flash for 7 days if the ‘Test’ button is not used to cancel it.

What is carbon monoxide?

co alarm memory

Carbon monoxide is a poisonous gas that cannot be seen, smelt or tasted and is produced when fuel doesn’t burn properly. The only way to detect carbon monoxide is with an audible CO alarm placed 1-3 metres away from any fuel burning appliance, such as a gas boiler, gas cooker or log burner.
