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 let you know that there has been a previous CO alarm activation within the past 30 days. However, if you have silenced an alarm activation, alarm memory will not be instigated immediately.
This new feature is particularly useful if you return home after a few days away or a holiday, providing you with time to ventilate your property and call a gas safe registered engineer to check your fuel-burning appliances. It’s also helpful when visiting a loved one’s home or for carers visiting clients and spotting the red LED flashing to know there has been recent carbon monoxide alarm activation and to seek proactive intervention.
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 your absence. The red warning light will continue to flash for 7 days if the ‘Test’ button is not used to cancel it.
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.
