## Description

Optical Smoke Alarms are recommended by British Standard 5839-6 for circulation areas. Detas Optical Smoke Alarms incorporate the latest optical sensing technology, which is more sensitive at detecting large particles of smoke which tend to be produced in greater amounts by slow smouldering fires. Suitable for use within hallways and landings, as well as living rooms and bedrooms. This is the new range of Deta alarms. These alarms ARE NOT compatible with previous ranges of Deta or any other brand of smoke alarms, therefore should only be used in new installations. These alarms can be installed, along with linked heat alarms (if required), to provide a fire detection system to comply with British Standard BS 5839: Pt.6 Grade D \"System incorporating one or more interlinked mains powered smoke alarms and heat alarms (if required), each with an integral stand-by supply. Wiring requirements:- 1.0mm or 1.5mm 6242Y Twin & Earth cable to the first alarm position, then 1.0mm or 1.5mm 6243Y 3 Core & Earth cable from the first alarm position to the second alarm and so on in a \"radial\" or \"daisy chain\" type circuit arrangement."

## Questions & Answers

**Q: Can I replace model 1151 with 1163? The reason why I asked was because that's what data salespeople were telling me but the 2 looks different.**
A: I used the 1163 to replace the 1151 as well, but it is not a direct replacement, 1163 is larger in size and the electrical plugs are different. The fitting screws are compatible though. So it is not a plug-n-play replacement.

**Q: Can someone please show me how to take it off to put a new battery in**
A: You don’t need to take the whole thing off.  The alarm is built in 2 different sections. The bit closest to the ceiling is attached. The outer cover turns a short distance then it lifts off, the battery is under this outer cover.

**Q: Where is the reset button?**
A: Not sure there is one just a test button

**Q: Can this model fit the 1151 mains powered smoke alarm fitting?**
A: When I used this to replace another Deta smoke alarm I could not find one that was a direct plug-in replacement - so I had to change the base plate as well. If in doubt use an electrician.
