DETA 1153 Mains Powered Smoke Alarms

The DETA 1153 is a mains powered smoke alarm with alkaline back-up batteries and has now been discontinued by the manufacturer. To ensure that owners of existing DETA 1150 systems can continue to use their current wiring, BRK have developed their 660MBX range to be fully compatible with your outgoing and remaining DETA alarms and bases. They are guaranteed to fit directly onto your existing bases so an electrician is not required.

The BRK 660MBX is an optical smoke alarm with replaceable alkaline battery backup. The thermally enhanced optical sensor is designed for use in hallways, bedrooms, landings and living areas, as well as rooms adjacent to kitchens or in rooms with open fires. Older alarms, particularly those with ionisation sensors, can be triggered by cooking fumes – the optical sensor in the 660MBX will reduce this significantly.

• Warranty: 5 year manufacturer's warranty

The simple installation process of the 660MBX replacement alarm removes the need for an electrician, though you must ensure that mains power to all interlinked alarms is cut before beginning work. The interlink wire can carry a live electric current between alarms if they are powered from different circuits.
