Common questions about manuals, registration, and support for this brand.
Press and hold the test button on your alarm for up to 10 seconds. The alarm will sound loudly, and the red LED will flash. If your alarms are interconnected, all other units in the system should also sound.
A single beep every 40 seconds typically indicates a low or depleted battery. If you have a model with replaceable batteries, replace them immediately. For mains-powered or 10-year sealed units, consult your user manual as it may indicate an end-of-life or sensor fault.
To properly housecode, press the housecode button on the back of the active unit until the amber light flashes rapidly, then once every 5 seconds. Repeat this within 15 minutes for all alarms you wish to interlink. Once completed, close the lids and perform a test to confirm the link.
Heat alarms are ideal for kitchens, garages, and boiler rooms where smoke alarms might trigger false alarms due to normal fumes, steam, or dust. They should be mounted on the ceiling or high on the wall according to the user manual's specifications.
