Discontinued Product - No Compatible Replacement
This product has been discontinued.View all
The DETA 1111 is a mains powered smoke alarm with a replaceable 9V alkaline back-up battery. As the DETA alarms are now discontinued, BRK have developed their 600MBX range to be fully backward-compatible with your outgoing and remaining DETA alarms and bases. The 670MBX is the ideal replacement for the 1111 alarm as it has been designed and tested to fit onto your existing alarm bases so you don’t even need an electrician.
Like the DETA 111 it replaces, the BRK 670MBX is an ionisation smoke alarm with alkaline battery backup. The ionisation sensor is best suited to detecting fast flaming fires and is typically installed in landing areas of the home. A central test/hush button makes maintenance of your alarm quick and simple. The replaceable 9V back-up battery will ensure you remain protected even in the event of a power cut.
The simple installation process of the 670MBX replacement alarm negates the need for an electrician, though you must ensure that mains power to all interlinked alarms is turned off before beginning work. The interlink wire can carry a live electric current between alarms if they are powered from different circuits.
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.

Good replacement smoke alarm I don't normally use deta smoke alarms but needed a single replacement to avoid replacing all interlinked alarms. Although only around 6 years old the existing deta alarms have been discontinued. However I managed to find this online that is the newer version of the existing model, and is compatible with all the other interlinked alarms. This site was a good find and the price was reasonable too. Delivered within the allocated time and a perfect replacement. Will definitely use safelincs again if this issue arises in the future.
