DETA 1153 Mains Powered Smoke Alarms

Discontinued Product - No compatible replacement

Please Note: The manufacturer has withdrawn from the European market and there is no compatible alternative that will fit into your existing system. Since it is not possible to interlink alarms from different manufacturers, new alarms will be needed throughout. The recommended replacement for the whole discontinued DETA range is the Kidde Firex series. This will require an electrician to replace your old DETA bases for new Kidde bases.

Product Overview

The DETA 1153 is a mains powered smoke alarm with alkaline back-up batteries and has now been discontinued by the manufacturer. To ensure that owners of existing DETA 1150 systems can continue to use their current wiring, BRK have developed their 660MBX range to be fully compatible with your outgoing and remaining DETA alarms and bases. They are guaranteed to fit directly onto your existing bases so an electrician is not required.

The BRK 660MBX is an optical smoke alarm with replaceable alkaline battery backup. The thermally enhanced optical sensor is designed for use in hallways, bedrooms, landings and living areas, as well as rooms adjacent to kitchens or in rooms with open fires. Older alarms, particularly those with ionisation sensors, can be triggered by cooking fumes – the optical sensor in the 660MBX will reduce this significantly.

  • Power: 230V mains powered with back-up battery
  • Back-up Battery: 9V alkaline back-up battery (included)
  • Warranty: 5 year manufacturer's warranty
  • Fits onto your existing DETA alarm push-fit base
    • BRK twist-fit base included to keep as a spare
  • Suitable for living rooms, bedrooms and downstairs hallways
  • Optical sensor provides quick detection of slow, smouldering fires
  • CE and Kitemarked to BS EN 14604: 2005
  • Performs its own self-checks every 48 seconds to ensure the alarm is functioning correctly
  • Test and silence button feature
  • Other DETA / BRK replacement kits are available to cover the full DETA 1110 and 1150 series
  • Product warranty and life commences from date of purchase

The simple installation process of the 660MBX replacement alarm removes 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.
