Replacement for DETA 1111 Mains Powered Smoke Alarms

The DETA 1111 is a mains powered smoke alarm with a replaceable 9V alkaline back-up battery. As the DETA alarms are now discontinued, BRK have developed their 600MBX range to be fully backward-compatible with your outgoing and remaining DETA alarms and bases. The 670MBX is the ideal replacement for the 1111 alarm as it has been designed and tested to fit onto your existing alarm bases so you don’t even need an electrician.

Like the DETA 111 it replaces, the BRK 670MBX is an ionisation smoke alarm with alkaline battery backup. The ionisation sensor is best suited to detecting fast flaming fires and is typically installed in landing areas of the home. A central test/hush button makes maintenance of your alarm quick and simple. The replaceable 9V back-up battery will ensure you remain protected even in the event of a power cut.

The simple installation process of the 670MBX replacement alarm negates the need for an electrician, though you must ensure that mains power to all interlinked alarms is turned off before beginning work. The interlink wire can carry a live electric current between alarms if they are powered from different circuits.
