Protect your home with the WisuAlarm Battery Powered Smoke Alarm (DHI-HY-SA13A), a straightforward and reliable smoke alarm designed to provide dependable fire detection in domestic environments.

Featuring a 10-year smoke detection sensor and powered by two replaceable AA batteries with an expected battery life of up to 5 years, this alarm offers long-term protection while making routine maintenance simple and cost-effective.

Unlike sealed battery models, the removable battery design makes this alarm particularly suitable for caravans, motorhomes, holiday homes and travel accommodation, allowing the batteries to be removed during transport, storage or periods when the property is unoccupied.

A low battery warning system provides both audible and visual alerts when the batteries require replacement, helping ensure the alarm remains operational.

Certified to EN14604 and UKCA requirements, the alarm produces an 85dB warning signal designed to provide clear audible notification in the event of a fire.

The integrated test and silence button allows users to regularly verify operation and temporarily silence nuisance alarms when required.

Designed for straightforward installation, the alarm is supplied with fixing screws and is suitable for a wide range of domestic applications including bedrooms, hallways, landings and living areas.

Suitable for coverage areas of 20–40m² in rooms with ceiling heights up to 8 metres, this compact smoke alarm provides practical and reliable fire protection for everyday use.
