In brief – Smoke Alarms will alarm when smoke is detected by the sensors within the unit whereas Heat Alarms will alarm when they detect a rapid rise in temperature in the atmosphere around the device. Heat Alarms have been specifically designed for areas with fumes and high humidity e.g. kitchens where cooking fumes are present and attics or garages where there is lots of dust and usually high humidity.
Over 50% of fires start in kitchens in domestic properties – installing a heat alarm in this room will mean you’re rapidly alerted to danger.
FireAngel Heat alarms have a Thermistek sensor. The Thermistek sensor detects rapid temperature increases. Its reaction to heat rather than smoke makes it ideal for installation in kitchen areas and garages in order to avoid false alarms caused by cooking and vehicle fumes.
Given that over 50% of domestic fires start in the kitchen, it’s paramount that you protect this area with an alarm to be alerted to danger quickly. FireAngel has a wide range of Kitchen Heat Alarms which have been specifically designed to be installed in the kitchen, and in areas with high fumes or humidity such as the garage or attic.
Unlike smoke alarms, a Kitchen Heat Alarm detects rapid rises of temperature, which stops any false alarms to cooking fumes from burnt toast!
Heat Alarms should be installed alongside smoke alarms to provide a rapid alert to all fire types across the home.
The guidance FireAngel offers on installing heat alarms is: Install heat alarms on the ceiling, ideally in the centre of a room. Install sufficient alarms to compensate for closed doors and obstacles. Install your heat alarm at a distance no greater than 5.3m from the farthest wall, no greater than 5.3m from a door to any room in which a fire might start and no greater than 5.3m from the next heat or smoke alarm. Keep in mind, this is only guidance. If you would like to discuss the positioning of any unit in more detail please contact our Customer Support Team.
Yes – heat alarms and smoke alarms detect fire in very different ways. Smoke alarms, as the name suggests, alert you to fires by detecting smoke, so if there’s a slow smouldering fire (which usually doesn’t give off a lot of heat) it could be missed for some time if a you only have a heat alarm installed. We would recommend you review the regulations specific to your area, but as a guide we recommend that homes have a smoke alarm in the hallway, landing and in the room most used in the daytime, alongside a heat alarm in the kitchen.
A Heat Alarm is perfect for detecting fires like those caused by faulty white goods, as they usually create a ‘blast’ of fire that’s very hot. Heat Alarms won’t false alarm to a dusty or humid room which makes it perfect for kitchens, utility rooms and garages where these items are usually found.
