TOCSIN 625 MICRO

TOC-625 Micro is a multi-channel gas detection system. The system can be configured with up to six gas detectors and two relay output modules. Any mix of the following gas detectors is possible.

Flammable Gases, Carbon Monoxide, Carbon Dioxide, Oxygen, Chlorine or Hydrogen Sulphide.

(please note for larger systems, IGD can provide a state of the art, industry first, intelligent gas detection system – 2-Wire Addressable Gas Detection , with up to 350 devices both detectors and third party devices)

The TOC 625 Micro is designed to be easily installed with advanced automatic setup features. Addressable gas detection systems allow you to quickly deploy an effective safety solution. The controller features Auto-Setup functions which enables auto-configuration of the gas detection system alarm levels, gas types and ranges:

  • Run FIND function at Startup when prompted
  • TOC-625 automatically finds connected devices
  • Detected devices are automatically installed
  • Alarm levels and outputs are automatically set

All detectors are addressable. These systems allow for the use of use of pre-calibrated detectors. Only a single cable is required to interconnect the controller, detectors and relay modules. Addressable gas detection systems of this type typically save up to 70% on installation costs.


There is also a pre-wired version (TOC-625-MCP) of the system using plug and socketed cables. This version allows for installation by people with no gas detection installation experience (we offer full advice to help provide you with the gas detection knowledge through our online training academy). Cables are available in 1M, 3M and 10M lengths that can be interconnected to make specific length cable runs. Refer to the TOC-625-MCP manual and data sheet for full information.

Follow IGD’s guide to Siting Gas Detectors to help determine best location. If in doubt call IGD for help and advice.
