Kidde's Firex range are hardwired smoke and heat alarms which have a 6 year guarantee and are BSI kitemarked therefore ensuring that level of quality would be consistent as it provided by the world's largest manufacturer. Ionisation and optical models have proven to be exceptional alongside heat alarms for situations which would prove to be unsuitable for smoke alarms such as kitchens and garages.


Both the models are mains powered and have a built in back-up power thereby complying with the current minimum requirements of that specific building.

Ionisation smoke alarms are available and are for use in case of emergencies wherein there may be an intense fire. For instance, electrical equipment igniting is far more likely to be a hazard rather than a slow smouldering one, for example furniture and bedding. They seem relatively more prone to nuisance alarms from cooking particles and steam near kitchens. They contain relatively low amount of Americium 241 , a radioactive material, which may be considered for future disposal
