Gas Safety Control Panels
The control panel is the brain of the system: it reads the sensing devices, runs the proving sequence, drives the solenoid valve and tells an operator why gas has been isolated.
- Combined interlock and proving panels are the UK norm
- Clear indicator lamps reduce needless call-outs
- Panels can usually be upgraded without repiping
System architecture
What the panel does
- Monitors extract and input air proving devices
- Runs the gas pressure proving test where fitted
- Energises and latches the gas solenoid valve
- Accepts gas detection, CO and CO₂ alarm inputs
- Provides volt-free outputs to a BMS and to ventilation controls
Reading panel indications
| Indication | Meaning | Operator action |
|---|---|---|
| Green GAS ON | All conditions met, valve open | Normal operation |
| Amber FAN FAIL | Extract or input air not proven | Check fans and filters, then reset |
| Red PROVING FAIL | Downstream leak or open tap | Close appliance taps, retry once, then call an engineer |
| Red EMERGENCY STOP | E-stop latched | Release the correct e-stop and reset the panel |
| Red GAS ALARM | Detection in alarm | Evacuate and call an engineer — do not reset |
| Flashing FAULT | Sensor, fuse or wiring fault | Engineer diagnosis required |
Upgrade and replacement
Obsolete panels with no spares, or panels without proving where a risk assessment now requires it, are replaced with a modern combined unit reusing the existing valve and sensing devices where they test good. The system is then fully recommissioned and recertified.

Frequently asked questions
Can I reset a gas alarm on the panel myself?
Never reset a gas, CO or CO₂ alarm. Evacuate, isolate at the emergency control valve and call a Gas Safe registered engineer.
Why does the panel keep blowing a fuse?
Usually a shorted solenoid coil or damaged cable in a hot canopy void. It needs electrical diagnosis, not a larger fuse.
