Gas Detection Systems

Gas Detection Systems

E3Point is a gas monitor capable of detecting the widest range of toxic and combustible gases found in commercial building spaces and outbuildings. It can be used as a standalone unit with single or dual gas detection or deployed as a networkable device; E3Point also functions with existing controller based gas monitoring systems and wired/wireless gas monitoring system components.


These modular dual gas detection systems are ideal for car parks, truck stops and battery charging areas.

Stand Alone Gas Detection Systems

The Geca CTR21 wall mount gas leak detector monitors natural gas, methane or LPG (depending on the model). The accompanying sensor is integrated onto the housing for ease of installation.

Technical specifications:

  • rating: IP44
  • first relay intervention: 10% LEL, second relay intervention: 20% LEL

Centralised Gas Detection Systems – multi zone

This equipment is primarily used for the detection of natural gas or LPG leaks in commercial and industrial environments. The gas units monitor up to 3 detection zones via the remote gas sensor.


  • DIN mount or panel mount options
  • monitor up to 3 zones (CTP21 only)
  • LED indication of LEL levels
  • test/reset push buttons
