Ionisation Smoke Alarms

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

      Ionisation Smoke Alarms

      Ionisation Smoke Alarms

      Some of the first smoke detectors produced, ionisation smoke alarms contain a weak radio-active source and react very quickly to fast flaming fires and any traces of smoke. While suitable for most rooms, we recommend ionisation smoke alarms for installation on landings. These alarms are not suitable for installation near kitchens or bathrooms as cooking fumes and steam can cause false alarms. For these locations it is recommended to install optical smoke detectors, which are less prone to false alarms.
