## Questions & Answers

**Q: so this is not scotland compliant only compliant for england and wales? do not buy for scotland as you cannot use it**
A: As the new Scottish legislation requires residents to have interlinked units, this one will not be compliant as it is standalone. Any unit from our FireAngel Pro range will be compliant though. 
Many Thanks
Gemma

**Q: Hello, Can this be affixed to the ceiling using magnets or heavy duty velcro strips?**
A: Yes I think you could use magnets or Velcro strips but i used small Rawl plugs into plaster board. Simples.

**Q: Can this be used to replace the discontinued model Deta 1151?**
A: We used it to replace an expired and discontinued fire angel model in a caravan ,as we didn’t want more holes drilled in the ceiling. I am sorry I don’t know if it was originally a Deta 1151 but all we had to do was use the original base and screw the new top on. Hope it helps.

**Q: I’ve been told I need to fit a heat alarm that will link with fire alarm; is this possible with this product?**
A: No

## Customer Reviews

### ⭐⭐⭐⭐⭐ Fault item
*by A***R on 5 September 2025*

This item has gone faulty with in the manufacturer warranty.Fireangel has a 5 years warranty and 10 years battery life.Can I get it replaced.

### ⭐⭐⭐⭐⭐ Excellent smoke alarms - FireAngel quality you can trust
*by M***H on 15 September 2025*

I'm a loyal FireAngel customer and these smoke alarms maintain the brand's excellent reputation. The quality and reliability are second to none, which is exactly what you want from a safety device.Installation is straightforward and they're up and running quickly. The optical sensor technology works perfectly - sensitive enough to detect real smoke threats but smart enough to ignore false alarms like vaping, which is a huge advantage over cheaper detectors.The alarm tone strikes the perfect balance - loud enough to wake you and alert the household, but not so overwhelming that it's painful. There's no annoying constant beeping during normal operation either.The 10-year battery life is fantastic - set and forget peace of mind. The white finish looks clean and unobtrusive on the ceiling.Pro tip: pair these with magnetic mounting pads (as mentioned in my other reviews) for incredibly easy installation without drilling.These are premium smoke alarms that justify the price with superior performance and reliability. When it comes to fire safety, I wouldn't trust anything else.Highly recommended for anyone serious about home safety.

### ⭐⭐⭐⭐ New fire alarm
*by I***R on 24 July 2025*
