Inter connectable Heat Detector is an essential safety device designed for environments where traditional optical or ionization smoke alarms may not perform effectively. Ideal for kitchens, lofts, garages, utility rooms, and humid or dusty areas, this mains-powered heat alarm provides reliable fire detection using advanced thermal sensing technology. It can be interlinked with up to 23 additional mains-powered alarms, ensuring whole-home protection through simultaneous alerts across all connected units.
Why Choose an Interconnectable Heat Detector?
Heat detectors are specifically engineered to identify rapid increases in temperature rather than smoke particles. This makes them perfect for locations where steam, dust, or cooking fumes may trigger false alarms in standard smoke detectors. When interconnected, any device detecting heat or fire will activate all units in the system, providing comprehensive and synchronized safety throughout the property.
Key Features of the Interconnectable Heat Detector
1. Interconnects with Up to 23 Other Mains Alarms
Create a linked safety network where all alarms sound if a single unit detects danger. Compatible with other heat, ionization, and optical alarms within the same system.
2. Alarm Memory Function
The unit features an intelligent memory indicator that helps identify which alarm in the network triggered first, making investigation faster and easier.
3. Test & Hush Function
A combined test and hush button allows routine testing and quick silencing of nuisance alarms without disabling the system.
4. Auto Reset After Activation
Once the hazard is cleared and temperatures fall, the detector automatically resets, restoring itself to normal operation.
5. Tamper-Resistant Locking Device
Prevents unauthorized removal of the alarm without tools, ensuring dependable long-term protection.
6. Mains Operation with Rechargeable Backup
Powered by 230V AC with a built-in, tamper-proof rechargeable lithium battery, allowing continuous operation even during power failure.
7. Professional Installation Recommended
Meets the requirements of UK building regulations for new housing and complies with Grade D fire safety standards. Installation by a qualified electrician is advised.
