Easichange® Replacement Heat Alarm for BRK 690MRL

Discontinued Product

The manufacturer has withdrawn from the European market and is no longer supplying compatible alternatives.

Product Overview

The BRKEHL Easichange® kit replaces the alarm head for the BRK 690MRL heat alarm powered by a lithium battery. The kit contains a BRK 690MRL alarm head, Easichange® tool, product manual and Quick Change Guide, plus an adhesive reminder note to stick on your fuse box.

Just like the 690MRL you are replacing, the BRKEHL is a mains powered heat alarm with a sealed lithium backup battery that will ensure you remain safe even in the event of a power cut. The heat alarm is designed to be installed in kitchens where a traditional smoke alarm may be falsely triggered by normal cooking fumes. The replacement fits on to your existing BRK 690MRL alarm base making installation quick and easy.

  • Direct replacement unit for the BRK 690MRL heat alarm
  • Genuine replacement alarm head made by BRK
  • Supplied with free Easichange® tool
  • Please note that BRK and First Alert are no longer manufacturing new stock for the European Market and while the products may have a 2018/19 manufacturing date they still provide a full 10 year lifespan and full warranty cover from date of purchase
  • Can be interlinked with up to 12 compatible alarms for earlier warning
  • Kitemarked and CE marked
  • Suitable for use in Grade D1 systems, complying with BS 5839-6: 2019
  • Fitted with a sealed lithium battery to prevent tampering and reduce maintenance
  • Single combined test & hush button
  • Simple to install onto existing twist-fit base
  • Safelincs Exclusive 5 Year Warranty
  • Product warranty and life commences from date of purchase

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.

Compatible Alarms

Below is a table of all alarms which can be interchanged using the same base plate and interlink system. Care should be taken to ensure the correct model is purchased to replace existing alarms. Optical smoke alarms can be used in place of ionisation smoke alarms, but heat alarms and smoke alarms serve different purposes and cannot be swapped.
