Product Overview

The BRK 600MBX series of mains powered alarms are available with ionisation, optical or heat sensor and feature a 9V alkaline back-up battery. Kitemarked to the latest British Standards, these BRK mains powered alarms are suitable for installations complying to BS 5839-6 Grade D2 and can be hard wire interlinked to form a smoke alarm system. Once interlinked, if one alarm detects a fire, it sounds and triggers all other interlinked alarms to also sound.

  • 230V mains powered with 9V alkaline back-up battery (included)
  • Kitemarked to BS EN 14604 (smoke alarms) and BS 5446-2 (heat alarm)
  • 5 year manufacturer's warranty
  • Please note that BRK are no longer manufacturing new stock for the European Market and while the products will have a 2018 manufacturing date they still provide a full 10 year lifespan and full warranty cover from date of purchase
  • 690MBX and 660MBX include slimline twist-fit base suitable for flush mounting
  • 670MBX includes push-fit base suitable for flush mounting and surface trunking
  • Suitable for installations complying to BS 5839-6: 2019 Grade D2
  • Available in three versions:
    • Ionisation smoke alarm (670MBX) responds quickly to fast flaming fires - used in landing areas
    • Optical smoke alarm (660MBX) responds quickly to smouldering fires - used in bedrooms, living rooms and hallways
    • Heat alarm (690MBX) responds to rate of increase in room temperature - used in kitchens and garages
  • Test and Hush Button Feature (Heat alarms only have Test functionality)
  • Up to 12 alarms can be hard wire interlinked within a single system
  • Suitable replacement for DETA alarms:
    • DETA 1151 & 1111: BRK 670MBX Ionisation Alarm
    • DETA 1153 & 1113: BRK 660MBX Thermally Enhanced Optical Alarm
    • DETA 1155 & 1115: BRK 690MBX Heat Alarm
  • Please note: alarms are sold separately
  • Product warranty and life commences from date of purchase
  • This alarm is also suitable for the updated 2022 Scottish legislation for fire alarms in homes

Please note: the packaging may show a product code of 770MBX and include a push-fit base but the alarm itself is still a 670MBX, as shown on the sticker on the back of the alarm head, and it is still compatible with existing twist-fit bases.

Please note: for surface-mounted wiring such as trunking the base plate included with these alarms is not suitable; please see the BRK 700 series with push-fit base instead.
