## Overview

The FireAngel HW1-R is a mains-powered heat alarm designed for kitchens, garages, and lofts, featuring Class A2 heat detection (54-70°C) that avoids false alarms from cooking fumes or humidity. It includes a 9V battery backup for continuous protection, can interconnect with up to 12 alarms for whole-home safety, and emits a loud 85 dB alert. With a 10-year lifespan and 5-year warranty, it offers reliable, long-lasting fire safety certified to BS EN 5446-2: 2003.

## Description

The HW1-R mains-powered Kitchen Heat Alarm includes a 9V battery backup and is designed for Class A2 detection. This heat alarm will sound a warning when the ambient temperature in a room is between 54°C and 70°C. HEAT SENSING TECHNOLOGY Heat alarms are ideal for areas with high humidity and cooking fumes where traditional smoke alarms aren't suitable. Suitable for kitchens, garages, and lofts, this heat fire alarm won’t be triggered by humidity, cooking fumes, or dust. INTERLINK MULTIPLE DEVICES The HW1-R smoke alarm functions perfectly as a standalone unit but can also be hardwired and interconnected with up to 12 mains-powered smoke (SW1), heat (HW1), or carbon monoxide (CW1) alarms. Once interlinked, all alarms will sound simultaneously if one is triggered, ensuring immediate alerts throughout the home, even from remote areas. TEST/SILENCE BUTTON To test the device, press the large test button for 5 seconds. A loud, high-pitched sound confirms that the alarm is functioning correctly. In case of a false alarm, press and hold the test button to temporarily silence the alarm for 10 minutes.

Review: I’m genuinely impressed with the FireAngel SW1 R mains powered smoke alarm. The build quality is exceptional and it performs significantly well, definitely a product you can trust to keep your home safe. That said, if you’re replacing an older smoke alarm from a different brand, be aware that this model may leave some gaps around the ceiling and could require replastering to get a neat finish. You can see this clearly in my photos. For another room, I discovered that the same company offers a standalone push fit base product. It’s much easier to secure, fills gaps left by older alarms, and makes removing the smoke alarm simpler than with the standard plate. It’s worth considering this option if you want a smoother installation. All that said, the SW1 R is a great product at a good price. It’s reliable, well made, and definitely does what it promises. Just make sure you consider the points above regarding installation, ceiling gaps, and alternatives, it will save you hassle in the long run.

Good quality smoke detector. Easy to replace previously fitted hard wired system. Good make used by our local Fire service

### ⭐⭐⭐⭐ Review
*by A***R on 28 September 2025*

Works as designed. Batteries included are completely dead on arrival. Your sensor will beep because the batteries are dead. Best to buy new quality batteries and do a test before connecting, the alarm should sound loud as if it is connected to power. Ordered both smoke and heat alarms, batteries dead in both.
