Kidde KF30 Mains Powered Heat Alarm with 9v Back-Up Battery

The Kidde Firex KF30 is a 230V mains powered heat alarm with a replaceable 9V alkaline back-up battery supplied as standard. It uses a thermistor sensor and alarms when it senses heat over 58°C, so it suits kitchens, garages and lofts where a smoke alarm would give nuisance alarms. It can be hard-wire interlinked with up to 23 other Kidde Firex mains alarms (optical, ionisation or heat), so when one unit detects danger every connected alarm sounds.
