## Overview

The FireAngel SW1-R is a mains-powered optical smoke alarm featuring a 9V backup battery, designed to detect all fire types including slow smouldering ones. 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 with a 10-year lifespan, ensuring reliable, long-term fire 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.
