Gas Leak Detection & Emergency Shut-off Systems
A gas detector alone does not protect a facility; protection comes from an interlocked system: a detector in the correct position, a control panel that receives the signal, a solenoid valve that cuts the gas immediately, and an audible alarm that reaches the site team. We design, install, interlock and test that system as one unit.
System components
- Gas detectors for kitchens and enclosed areas
- Detectors suited to industrial and hazardous environments
- Control and alarm panels with varying zone counts
- Solenoid emergency shut-off valve
- Audible and visual alarm
- Interlock with ventilation where required
Where the detector goes
Detector position depends on the gas behaviour, air movement in the space, appliance locations and likely accumulation points; a wrong position makes the detector respond late or not at all.
Periodic testing
The system is tested periodically by verifying detector response, signal arrival at the panel and actual valve closure, with the result recorded in the maintenance log.
Deliverables
- Detector position and zone drawing
- Installed and interlocked system
- Documented functional test
- Site team briefing on the alarm procedure

Frequently asked questions
Can detection be added to an existing network?
Yes. It starts with a survey of the space and appliances to set detector positions and the shut-off valve location, followed by installation, interlock and testing.
Why must the detector be linked to a shut-off valve?
Because an alarm alone depends on someone being there to react, while an interlocked valve cuts the gas source automatically as soon as the threshold is exceeded.
