12V Relay Output Switching Gas Alarm – Smart Control Gas Leak Detector

Keep your space safer and more controlled with this 12V relay output switching gas alarm, designed to detect gas leaks and automatically trigger external devices when danger is detected. Ideal for homes, workshops, garages, caravans and small commercial areas, it provides both an audible warning and a control signal through its relay output for added protection.

Reliable Gas Leak Detection with Audible Alarm

This gas alarm continuously monitors the air for the presence of combustible gases (model-dependent, such as natural gas, LPG or methane). When the gas concentration reaches a preset threshold, the detector activates a loud built-in alarm to warn people nearby.

The high-decibel siren is designed to be heard clearly, helping occupants react quickly—opening windows, shutting off appliances and leaving the area if needed. It’s a key safety layer anywhere gas is used for cooking, heating or industrial processes.

12V Relay Output for Automatic Switching Control

A major feature of this unit is its 12V relay output, which allows it to switch or control external devices automatically when a leak is detected. Depending on how it’s wired and the devices used, you can:

• Drive an external siren or strobe light
  
• Control a gas shut-off solenoid valve
  
• Activate an exhaust fan or ventilation system
  
• Trigger a central alarm panel or automation system
  

The relay output acts like an electronic switch, closing or opening the circuit when the alarm condition occurs. This makes the device not just a detector, but an active control point in a wider safety or automation setup.

Flexible Use in Home and Light Commercial Environments

Designed for 12V systems, this gas alarm is well suited for:

• Domestic kitchens with gas stoves
  
• Boiler or heater rooms
  
• Garages, small workshops and storage areas
  
• Caravans, motorhomes and small boats (with suitable 12V power and correct installation)
  

Its compact design and low-voltage operation make it easy to integrate into existing low-voltage alarm or control systems, especially where central panels or 12V power supplies are already in place.

Practical Safety Upgrade

If you need more than just a stand-alone beep-only gas detector, this 12V relay output switching gas alarm offers both early warning and automatic response capability. By combining sound, detection and relay control, it helps reduce risk and supports smarter, more proactive gas safety in homes and small commercial spaces.
