These alarms, which are powered by a single 9V PP3 alkaline battery, are suited for all situations where Deaf and Hard of Hearing people require early warning of a fire outbreak, while also giving a strong auditory alarm for those with good hearing. Ionisation, optical, and heat alarms with audible sounders are suitable for all household contexts..
If you need smoke detection in a kitchen or laundry environment we recommend the Silent Alert Heat Detector available here

Ionisation alarms respond quickly to fire and should be used upstairs.
