The DETA 1111 and 1113 are mains powered smoke alarms with a replaceable 9V alkaline back-up battery. As the DETA alarms are now discontinued, easichange® have developed a range of replacements to be fully backward-compatible with your outgoing DETA alarms and their mounting plates. The SBBRKSM is the ideal replacement for the 1111 and 1113 alarms as it has been designed and tested to fit onto your existing alarm bases so you don't even need an electrician.

The SBBRKSM is a mains powered smoke alarm with a replaceable 9V alkaline backup battery, like the DETA 1111 and 1113 that it replaces, to ensure you remain protected even in the event of a power cut. The optical sensor technology improves on the detection of slow smouldering fires and reduces the chances of false activations. A central test/hush button makes maintenance of your alarm quick and simple. Featuring a hardwire interlink allowing compatible easichange® alarms to communicate with each other over the same wiring as your old DETA alarms, so that all will sound the alarm if one detects a fire.

  • Suitable for bedrooms, living rooms and downstairs hallways
  • Power: 230V mains powered with back-up battery
  • Back-up Battery: 9V alkaline back-up battery (included)
  • Warranty: 3 year manufacturer's warranty
  • Simple replacement process with Quick Change Guide
  • Fits onto your existing DETA alarm mounting plate and electrical connector plug
  • Optical sensor provides quick detection of slow, smouldering fires
  • Supplied with FREE easichange® replacement tool
  • Smoke alarm CE Marked, UKCA Marked, and Kitemarked to BS EN 14604: 2005
  • Adaptor plate and assembled replacement alarm tested and approved by TÜV Austria
  • Complies with BS 5839-6: 2019 Grade D2 requirements
  • Performs its own self-checks every 48 seconds to ensure the alarm is functioning correctly
  • Test and silence button feature
  • Replacement also available for the DETA 1115 mains powered heat alarm

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.
