Product Overview

The BRKEOL Easichange® kit replaces the BRK 660MRL and 670MRL smoke alarms. The kit consists of the replacement BRK 660MRL alarm head, Easichange® removal tool, quick change guide, product manual and a reminder sticker to place in your fuse box.

Like the 660MRL and 670MRL that it replaces, the BRKEOL is a mains powered smoke alarm with a sealed lithium backup battery. The optical sensor technology improves upon the detection of slow smouldering fires and reduces the chances of false activations. Featuring a hardwire interlink with up to 12 compatible devices (see the Interlink tab for more details) this alarm is simple to install and maintain.

  • Genuine replacement for BRK 660MRL and 670MRL alarm heads
  • Simple replacement procedure with Quick Change Guide
  • Interlink with up to 12 compatible alarms
  • 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
  • Single test / hush button
  • Optical sensor for improved detection and reduced false alarms
  • Supplied with FREE Easichange® replacement tool
  • Complies with BS 5839-6: 2019 for Grade D1 systems
  • Sealed lithium backup battery
  • 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.
