Product Overview

This BRK 660MBX is a direct replacement for your outgoing BRK 660MBX optical smoke alarm which use replaceable alkaline batteries. Optical smoke detectors such as the 660MBX are largely replacing the older ionisation smoke detection technology and are better at detecting slow, smouldering fires. The 600 series alarms all use the same base so your new alarm is guaranteed to fit and be compatible with your existing system.

The supplied BRK 660MBX is a thermally enhanced optical smoke alarm ideal for most rooms in the house such as hallways, living rooms, bedrooms, and landings, including rooms that are usually covered by traditional ionisation alarms. This alarm features a central test and hush button making maintenance very easy while a replaceable 9V alkaline backup battery ensures that it continues to operate even during a power failure, so you are never without protection.

  • Genuine BRK 660MBX replacement optical smoke alarm head
  • 9V alkaline backup battery (included)
  • CE and Kitemarked to BS EN 14604: 2005
  • Fits onto your existing BRK twist-fit alarm base (spare included)
  • Suitable for installations complying to BS 5839-6: 2019 Grade D2
  • Replacement also available for the BRK 690MBX heat alarm
  • An interlinked system provides the earliest possible warning of fire
  • Test and hush button feature
  • Manuacturer's 5 Year Warranty
  • Product warranty and life commences from date of purchase

The simple installation process of the 660MBX 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.
