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.
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.
