Review: Great and reliable product - I purchased this fire alarm in 2023, and it has been a fantastic product from day one. It came with a one-year battery guarantee, and it worked flawlessly all the way up until yesterday, when I believe the battery finally died. During the time I had it, I never experienced a single issue-the performance was excellent and incredibly reliable. The only real downside is the battery itself. It seems to be irreplaceable, which is a shame because the alarm is otherwise a quality product. If the manufacturer could move toward a greener, more sustainable design that allows for battery replacement, it would make this product both longer-lasting and more environmentally friendly. Overall, I would still recommend this alarm to anyone looking for a dependable option. If you have any questions about my experience, feel free to drop me a message, I’m happy to help.
Review: Smoke alarms that actually work and don’t go off for no reason - I picked up the FireAngel SB1-R smoke alarms after getting tired of my old detectors constantly startling me every time I made toast. I liked the idea of them being toast proof and figured it was worth a shot. Installation was a breeze since they come with everything you need right in the box. I mounted a couple in my home and immediately felt a lot more at ease knowing I had reliable protection. One thing I really like is the replaceable battery feature. It’s nice knowing I won't have to deal with that annoying chirping sound when the battery dies. Instead, I can just swap it out whenever I need to, which is a plus in my book. What really sold me was the test/silence button. The first time I tested it, I felt such relief when it activated without a hitch. It also gives me peace of mind knowing I can silence it easily if there’s a false alarm. Plus, I haven’t had a single nuisance alert from the kitchen since I installed them. Overall, I’m really happy with these smoke alarms. They’re effective, straightforward, and really do serve their purpose well. At the price point for a 2-pack, I think it’s a solid investment in safety without breaking the bank. I’d recommend them to anyone who wants reliable smoke detection and doesn’t want to deal with the frustration of false alarms.

## Features

- EARLY WARNING SMOKE DETECTOR: The optical smoke alarm makes protecting your home simple. The optical smoke sensing chamber works by 'seeing' smoke as it enters the alarm, perfect for slow burning fires with thick white smoke.
- TOAST PROOF: The high performance optical sensors ensure the FireAngel SB1-R is less prone to false alarms from cooking fumes, so you can enjoy your breakfast in peace.
- TEST/HUSH BUTTON: Press the large test button to ensure your Fire Angel smoke alarm is working properly. A loud, high-pitched sound will verify it. To silence a false alarm, press and hold the button for 5 seconds.
- 1 YEAR BATTERY: Each battery operated smoke alarm comes with a 1 year, replaceable 9V battery. When the smoke alarm battery is low, the device will 'chirp' and the red LED will flash once every 32 seconds. Replace the battery ASAP.
- EASY INSTALLATION: Each FireAngel smoke alarm comes with a removable base plate. Attach the base plate to the ceiling using the screws provided. After inserting the battery, push and twist the alarm clockwise onto the base plate.
- SAFETY ASSURED: The SB1-R alarm holds both CE and UKCA marks and has been certified to BS EN14604:2005. Suitable for domestic properties including mobile homes and caravans. Not suitable for commercial properties. Includes a 3-year warranty.
- FIREANGEL HOME PROTECTION: In addition to our smoke alarms, we offer a wide range of other safety products designed to protect you and your family. Choose from smart and wireless devices, as well as standard carbon monoxide and heat alarms.

## Questions & Answers

**Q: Keeps going off randomly and has worn out 2 batteries in 6 months?**
A: False alarms are commonly caused by something contaminating the sensor within the unit - usually dust particles or small insects. This an be easily rectified by using the hose from your vacuum cleaner and cleaning around the outside of the alarm. 
In the unlikely event that cleaning the unit does not resolve the issue, please give our helpful Technical Support team a call on 0800 141 2561 and someone will be happy to help you further.
Many Thanks, Gemma H

**Q: Keeps beeping 3 times after install? No indication why?**
A: We tossed ours in the bin, it kept going off on the stair landing every time the steam from the bathroom hit it.
It would even go off when nothing was there to make it go off.
It was brand new but went in the bin,

**Q: Can i use glue to stick onto the ceiling? i am unable to remove my magnet, and need to reposition this elsewhere! thanks**
A: My device is attached to a back plate which is screwed to the ceiling. This enables me to remove it from the site when decorating.

**Q: Where are these made please**
A: All of our units are manufactured in Poland. Many Thanks,  Gemma

### ⭐⭐⭐⭐ Small and mighty
*by X***C on 28 October 2024*

This little smoke alarm packs a punch! I was immediately impressed by its compact size and how discreetly it fits into my home. The installation was a breeze, and I opted for adhesive velcro strips instead of drilling holes. One of the first things I noticed was the powerful alarm. Trust me, it's loud enough to wake even the deepest sleeper! While the battery life isn't quite a year as advertised (I've had to replace them after about 4 months), it's a small price to pay for peace of mind. Interestingly, the alarm has gone off a couple of times due to hairspray and once seemingly at random. Although these weren't fire-related incidents, it's reassuring to know that the alarm is sensitive and responsive. Overall, the FireAngel SB1-R is an affordable and reliable smoke alarm that's easy to install and blends seamlessly into any home.
