Battery Powered Home Fire Alarm Pack: 2 Smoke Detectors & 1 Heat Detector

The Battery Powered Home Fire Alarm Pack – 2 Smoke & 1 Heat provides reliable, long-term fire protection for key areas of a domestic property.

This pack includes two DHI-HY-SA40A battery smoke alarms and one DHI-HY-HT10A battery heat alarm, offering a balanced solution for detecting smoke in circulation spaces and heat in higher-risk rooms such as kitchens.

This kit includes:

• 2 × DHI-HY-SA40A Standalone Smoke Alarms

• 1 × DHI-HY-HT10A Standalone Heat Alarm

Powered by sealed 10-year lithium batteries, all units operate independently without mains wiring, making them ideal for retrofit installations and straightforward home upgrades.

This pack is particularly suitable for 2–3 bedroom houses, flats, starter homes and owner-occupied properties requiring dependable, low-maintenance fire detection.

Each alarm delivers a loud 85 dB(A) warning at 3 metres, along with clear LED status indication and a combined test and silence button for simple operation.
