The DETA 1111 and 1113 are mains powered smoke alarms with a replaceable 9V alkaline backup battery, and although they are now discontinued, easichange® has created backward compatible replacements that fit the original DETA mounting plates. Designed and tested to attach to existing bases without needing an electrician.

The SBBRKSM mirrors the original alarms’ mains power and 9V backup, with an improved optical sensor technology for better detection of slow, smouldering fires with fewer false alarms. Featuring a central test/hush button for easy maintenance and a hardwire interlink ensuring compatibility with other easichange® alarms even capable of communicating over the same wiring as your old DETA units.
