Ensure the mains power supply is via a fused spur and installed in accordance with local 

installation wiring regulations.

Check cable and glands are of suitable type for both the area of application and load carrying 

capacity. 

Ensure terminations via glands provide a positive seal.

Leave all interfaces unplugged and check installation cabling terminations following IGD 

publication ref “Cable checks T625-700-920.PDF”.

Check the shipping TOC-625 SET UP REPORT to check how the controller and interfacing 

detectors and nodes have been configured. Ensure that the detector addresses match the 

document.

Plug in the connector  3   and power up the system. Check that all connected devices indicate 

that they have power and are communicating correctly.

Allow at least 1 hour for the detectors to correctly warm up and stabilise.

During this period, if the relay outputs are being used check the cabling then plug in and test 

using the TST RLY function the relay action.

During this period if the analogue outputs are being used check the cabling to connector  1  , 

plug in and test using the  OUTPUT 1, 2 or 3 functions.

After warm up is complete use instrument air or Nitrogen as appropriate to check the detector 

zero reading. Adjust if necessary (see later “zero and calibration function” section).

After warm up is complete use a suitable known calibration gas to check the detector calibration 

reading. Adjust if necessary (see later “zero and calibration function” section).

Complete any site paperwork as necessary and instruct the site responsible person regarding 

day to day operation (see later section “ user operation “). 

Use the CHECK function to ensure detector channels are correctly set up and calibrated (see 

section Addendum 1).

In the event that the controller needs amendment to set up follow the instructions in the following 
sections.

a) Adding detectors or nodes to the controller or complete set up

b) Adding or changing alarm levels

c) Assigning relay outputs

d) Zero and Calibration Function (detectors)

e) Zero and Calibration Function (analogue outputs)
