## Overview

The FireAngel SW1-R is a mains-powered optical smoke alarm featuring a 9V backup battery, capable of detecting all fire types including slow smouldering fires. It supports hardwired interconnection of up to 12 alarms for comprehensive home coverage, includes a large test/silence button, and is certified to BS EN 14604:2005. Designed for reliability and ease of use, it offers a 10-year product lifespan and is ideal for installation in multiple rooms to ensure maximum safety.

## Description

SW1-R mains-powered optical smoke alarms are equipped with a 9V backup battery, making it easy and effective to protect your home. In the event of a fire, the alarm emits a loud 85dB sound at 3 metres, accompanied by LED visual indicators. OPTICAL SENSOR: The optical smoke sensing chamber ‘sees’ smoke as it enters the alarm, reducing the likelihood of false alarms. It is ideal for slow-burning fires that produce thick white smoke. INTERLINK MULTIPLE DEVICES: The SW1-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 8 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.
