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. Where your alarm is installed can trigger nuisance alarms if not correctly placed, for example too close to doors or windows.

We offer a broad range of wireless alarms which are becoming increasingly sought-after across the world, and these innovative fire alarm systems are now as effective as wired alarms due to the improvements in radio technology over the past 20 years.
