Gas systems built to sit in the safe zone, not the redline.
Gas detection interlocks, boiler plant controls and emergency shutoff systems for commercial buildings — designed, installed and commissioned by BMS engineers.
Gas locked out. Interlock tripped. Boiler on fault.
If your gas has shut off unexpectedly, a BMS alarm won't clear, or an engineer has told you the interlock has tripped — that's exactly what we fix. Same-day callout, 24/7.
Gas Interlock Tripped / Won't Reset
Ventilation proving fault, gas valve won't re-energise, interlock panel showing lockout — common after a fire alarm test or power cut.
No Gas to Kitchen / Plant Room
Gas supply cut with no obvious leak — usually a failed proving switch, tripped ESV or a BMS input reading incorrectly.
Boiler Gas Fault / Lockout
Burner won't fire, gas train showing fault, low fire/high fire hunting — burner management and gas train diagnostics.
BMS Gas Alarm Won't Clear
Persistent alarm on Trend, Tridium, Honeywell, EcoStruxure or Metasys with no visible cause — sensor, wiring or logic fault diagnosis.
Gas systems. Built, wired, commissioned.
Every install integrates with your existing BMS head-end — Trend, Tridium/Niagara, Honeywell, Schneider EcoStruxure or Johnson Controls Metasys. Compliant with DW/172, IGEM/UP/19 and gas safety regulations.
Gas Detection Interlocks
Automatic gas shutoff on leak detection, wired into ventilation proving, extract fan status and BMS alarm reporting. Compliant with DW/172.
Boiler Plant Gas Controls
Burner management, gas train monitoring, low/high fire control and safety shutoff valve wiring for commercial boiler plant, with BMS-level fault diagnostics.
Emergency Shutoff Valves (ESV)
ESV supply, installation, integration and annual testing for commercial kitchens, plant rooms and industrial gas lines.
Gas Proving Systems
Ventilation proving, damper end-switch wiring and airflow interlocks that stop gas flow until safe conditions are confirmed.
Gas Panel Fault Finding
Diagnostics and repair for existing gas interlock panels, relay banks and I/O — including systems we didn't originally install.
Gas Safety Compliance & Testing
Annual interlock testing, gas safety certification support and BMS alarm log reporting for insurance and compliance audits.
Panels we've built and commissioned.
A look inside recent gas interlock and BMS control panel builds — cabling, relay banks and I/O termination done to spec.
Gas BMS, explained.
Who installs gas detection interlock systems for commercial buildings?
Redline Gas Systems designs and installs gas detection interlocks that automatically shut off gas supply when a leak is detected, integrated directly with the building's BMS. 24/7 emergency, same-day callout available.
What is a gas interlock system and why is it required?
A gas interlock system prevents gas flow to an appliance unless ventilation and safety conditions are met. It's a legal requirement in most commercial kitchens and plant rooms under DW/172 and gas safety regulations.
Can an existing BMS be integrated with gas safety shutoff valves?
Yes. We integrate emergency shutoff valves into existing BMS platforms — Trend, Tridium/Niagara, Honeywell, Schneider EcoStruxure and Johnson Controls Metasys — without replacing the head-end.
How much does a commercial gas interlock system cost?
Cost depends on the number of gas appliances, existing BMS infrastructure and building size. We provide a fixed quote after a site survey.
Why has my gas interlock tripped and won't reset?
Usually a ventilation proving fault, a failed extract fan status signal, or a gas valve that hasn't re-energised after a power cut or fire alarm test. We diagnose and reset on-site, same day.
Why is there no gas to my commercial kitchen?
Most commonly a tripped ESV, a proving switch fault or an incorrect BMS input reading — not always a genuine leak. We identify the fault and restore supply safely.
Who fixes gas boiler lockouts and burner faults in commercial buildings?
Redline Gas Systems diagnoses burner management faults, gas train issues and boiler lockouts, and clears BMS-level gas alarms that won't reset.
Do you work on gas interlock systems you didn't originally install?
Yes. We fault-find and repair existing gas interlock panels, ESVs and BMS gas integrations regardless of who installed them.
