Product Overview

The BRK 770MBX alarm contains an identical replacement alarm head for your outgoing BRK 670MBX ionisation smoke alarm which uses replaceable alkaline batteries. The only difference is that the spare base supplied is a push-fit version rather than the twist-fit you already have installed. This replacement detector head fits directly onto your existing twist-fit base and is guaranteed to be compatible with your existing system.

The supplied 670MBX / 770MBX is an ionisation smoke alarm ideal for landings areas and detects fast flaming fires quickly. 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 670MBX replacement ionisation 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 push-fit base included)
  • Suitable for installations complying to BS 5839-6: 2019 Grade D2
  • 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 670MBX / 770MBX 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.
