Discontinued Product

This product has been discontinued.

Product Overview

The BRKEOL Easichange® Kit is the replacement for the alarm heads of the BRK 760MRL and 770MRL smoke alarms with lithium battery backup. The BRK 660MRL optical alarm head provides quicker and more accurate detection of slow smouldering fires while being less prone to false activation. Included in the kit are the replacement alarm head, quick change guide and full product manual, plus the supplied free Easichange® tool helps with the quick and easy installation of your new alarm.

  • Genuine replacement head for BRK alarms
  • Advanced optical smoke detection
  • Sealed lithium battery - no need to replace for the life of the alarm
  • 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
  • Suitable for use in Grade D1 systems
  • Complies with BS 5839-6: 2019
  • Can be interlinked with up to 12 compatible alarms
  • Safelincs Exclusive 5 Year Warranty
  • Combined test & hush button
  • Quick change guide and FREE Easichange® tool for simple replacement
  • 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.
