Product Overview

The SBBRKHE easichange® kit replaces the discontinued BRK 690MBX heat alarm and fits onto your existing BRK twist-fit alarm baseplate so there's no need for any DIY or an electrician. The kit consists of the replacement heat alarm head with pre-connected easichange® adaptor, an easichange® removal tool, a quick change guide, and the full alarm manual.

The SBBRKHE is a mains powered heat alarm with a replaceable 9V alkaline backup battery like the 690MBX that it replaces. Heat alarms detect the temperature of the room they're in and activate when it gets abnormally hot, typically from 55°C. They are designed for rooms like kitchens and garages where steam, fumes, and dust are expected to cause false activations in smoke alarms. Featuring a hardwire interlink, compatible easichange® alarms communicate with each other over the same wiring as your old BRK alarms, so that all will sound the alarm if one detects a fire.

  • Heat detector replacement for BRK 690MBX alarm heads
  • Simple replacement process with Quick Change Guide
  • Fits onto your existing BRK twist-fit alarm baseplate
  • Heat sensor detects unnaturally high temperatures to avoid false alarms from fumes and steam
  • BRK alarms allow linking up to 12 units, while a system of easichange® alarms supports up to 40
  • Supplied with FREE easichange® replacement tool
  • Single test / hush button for easy maintenance and silencing false alarms
  • Heat alarm CE Marked and Kitemarked to BS 5446-2: 2003
  • Adaptor plate and assembled replacement alarm tested and approved by TÜV Austria
  • Complies with BS 5839-6: 2019 Grade D2 requirements
  • An interlinked system provides the earliest possible warning of fire
  • Replaceable 9V alkaline backup battery
  • 3 year manufacturer warranty

The simple installation process of the easichange® replacement kits negates 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.

Please Note: We recommend replacing all alarms in the system together to maintain optimum system operation; failing to do so may compromise interlink performance.

Compatible Alarms

It is important to select the correct easichange® alarm to replace your obsolete BRK models. The table below will help you select the correct replacement alarm. Please note that you can replace your existing BRK optical and ionisation alarms with an easichange optical alarm, however your BRK heat alarm can only be replaced with an easichange heat alarm. Please see our guide on the BRK 600 & 700 series for assistance in determining your model.

Please Note: We recommend replacing all alarms in the system together to maintain optimum system operation; failing to do so may compromise interlink performance.

Installation

The simple installation process of the easichange® replacement kits, described below, negates 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.

Installation Steps

  1. Turn off the power at your fuse box or consumer unit.
    • Take care to turn off all circuits powering any of your alarms, as the interlink wire can carry a live electric current.
  2. Remove your old BRK smoke or heat alarm from its baseplate by twisting and the unplugging the connector.
  3. Insert the supplied 9V battery into your easichange® replacement alarm and close the unit securely.
    • Test the alarm to make sure it is powered up from the backup battery!
  4. Install the alarm on your old BRK baseplate:
    • Connect the plug so that the wires of the connector line up with the pins on the alarm.
    • Twist the alarm fully onto the baseplate.
  5. Repeat steps 2 to 4 for all of your old BRK alarms.
    • We recommend replacing all alarms in the system together to maintain optimum system operation; failing to do so may compromise interlink performance.
  6. Turn the power back on at the fuse box.
  7. Test each of your smoke alarms separately to ensure the whole system is functioning correctly. When you test one alarm, they should all sound, however it is important to press the test button on each alarm too.
