The Kidde Professional Series alarms can interlink with up to 23 inter-connectible alarms, which means that all alarms will sound if any detect smoke or heat. This K30C Alarm detects heat of above 58°C (Class A2) and is recommended to be used in conjunction with interconnected smoke alarms. It is 230 volt mains powered, with a battery back-up in the event of a power failure. A Hush™ button allows temporary silencing of nuisance alarms caused by cooking or steam and resets automatically. In addition, this button is used to check the alarm operation. A lock-out feature prevents the alarm from being attached/fitted unless the back-up battery is installed. The alarm has an impressive sound rating of 85 decibel at 3 metres. For convenience, it has a front-loading battery door to allow the battery to be changed without removing the alarm.
