FireAngel SW1‑R Mains Optical Smoke Alarm with 9V Battery Back‑Up

The FireAngel SW1‑R Smoke Alarm offers comprehensive and reliable fire protection for your home, designed with user-friendly features to make safety simple. Mains powered from a 230V supply and equipped with a 9V battery back-up, it ensures continuous operation even in the event of a power cut, providing constant peace of mind.

Featuring advanced optical smoke detection technology, this alarm is highly effective at detecting slow‑smouldering fires, such as those caused by electrical faults or overheated wiring, while significantly reducing the risk of false alarms from cooking fumes or steam. Its modern, low‑profile design is both discreet and aesthetically pleasing, complemented by a pre‑fitted ceiling base for quicker and easier installations.

A prominent central test and silence button simplifies the essential weekly testing procedure and allows you to temporarily silence nuisance alarms. Clear LED operating indicators provide an immediate visual status for power, fault, and alarm conditions, and a low battery warning indicator ensures you are never caught unprepared. The alarm’s innovative safety clip prevents installation without a battery in place, guaranteeing the back‑up power source is always active.

For enhanced protection, the SW1‑R supports multi‑alarm interconnection with up to 12 compatible FireAngel units (including smoke, heat, and carbon monoxide alarms). When one alarm detects a threat, all interconnected units will sound, providing an immediate, whole‑home alert to ensure a swift evacuation. This mains powered smoke alarm has undergone rigorous independent testing to meet the highest standards of quality and longevity.
