Home Battery Powered Fire Alarm Pack: 3 Smoke, 1 Heat & CO

The Home Battery Powered Fire Alarm Pack – 3 Smoke, 1 Heat & CO provides comprehensive protection against fire and carbon monoxide in domestic properties.

Suitable for 3–4 bedroom homes, rental properties, HMOs and holiday lets, this pack delivers reliable detection across circulation areas, kitchens and rooms containing fuel-burning appliances.

Pack includes:

• 3 × DHI-HY-SA40A 10-year sealed battery smoke alarms
• 1 × DHI-HY-HT10A 10-year sealed battery heat alarm
• 1 × DHI-HY-GC20D 10-year battery carbon monoxide alarm

The system includes three WisuAlarm DHI-HY-SA40A battery smoke alarms, one DHI-HY-HT10A battery heat alarm and one DHI-HY-GC20D standalone carbon monoxide alarm.

All smoke and heat alarms are powered by sealed 10-year lithium batteries, removing the need for wiring and reducing maintenance requirements.

The smoke alarms use advanced photoelectric sensing technology to detect smoke quickly while reducing nuisance alarms. The heat alarm uses a high-precision thermistor sensor, making it ideal for kitchens and garages where smoke alarms may be unsuitable.

The carbon monoxide alarm uses a high-performance electrochemical sensor to accurately detect CO leakage and respond quickly when dangerous levels are present.

Each device features a combined test and hush function for simple maintenance and user control. Clear LED status indicators provide visible confirmation of power, alarm and fault conditions.

All units are designed for straightforward ceiling or wall mounting, making installation simple for homeowners and landlords.
