Ionisation Smoke Alarms

A comprehensive range of battery operated as well as mains powered smoke alarms using ionisation technology. Ionisation alarms are very effective for detecting fast-flaming fire. We recommend ionisation alarms for landings and office spaces. For areas prone to false alarms, use optical smoke alarms.

Ionisation Smoke Alarms

Ionisation Smoke Alarms

Ionisation smoke alarms were some of the first smoke alarms produced. They contain a weak radio-active source and react very fast to fast flaming fires and any traces of smoke. We recommend them on landings but not anywhere near kitchens where the smoke from burn toast tends to set them off even at a distance.
