Heat Detectors
How to choose heat detectors
Sub-type and placement
Choose Fire & Gas Safety for a warehouse or corridor, but pick Home & Garden for a shed where colour match matters.
Housing material
Material: plastic suits a quick fit, while metal or steel suits humid or rough spaces.
Visibility vs decor
Colour: red or green/red aids safety checks, while white, black or silver disappears into decor.
Unit type
Some listings are sensor modules or transmitters, not standalone alarms, so match them to your existing system.
Power connection
Decide between a mains-linked unit and a self-contained module based on your building's wiring.
What's good
- Fire & Gas Safety tagged units include heat and smoke detectors built for corridors and warehouses, giving focused fire cover.
- Home & Garden listings often use plastic or plastic/wood bodies in white or black, so they blend into a room.
- Metal and steel housed options resist knocks better than pure plastic ones.
- The colour range (red, green/red, silver) lets you pick a visible safety marker or a discreet fitting.
Things to watch
- Plastic bodies keep weight low, but they can soften in a hot loft where metal or steel would hold shape.
- Mains-powered detectors in the Fire & Gas Safety group need fixed wiring, unlike clip-on modules.
- Copper or metal/plastic mixes add mass, so ceiling fixings must be stronger.
- Home & Garden styles may favour looks over alarm volume, which can fall short in a commercial set-up.
Care & maintenance
Clean vents
Dust the vents on plastic and plastic/wood units so heat sensing stays clear.
Exercise alarms
Test resettable manual call points and buzzers every few months to confirm they still sound.
Watch for rust
Check metal or steel housings for corrosion if used in damp garden spots.
Verify sensors
For modules with over-temperature alarms, verify the trigger with warm air once a year.
