Page 11 Note that certain detector 600s types, Oxygen sensors in particular may take up to 2 hours to fully stabilise. During the warm up period check that each connected detector or device has power and communication.
Page 12: Supplied Set Up
Normal Operation In normal operation mode the TOC-625 communicates to each detector or node in turn and displays the data on screen. In normal mode the back light will switch off. Pressing the button once will activate the back light, each button press then cycles the display through each channel.
Page 13 Analogue Which analogue output relates to this channel. Output Note there are three analogue outputs available on the TOC-625 Channel If the control panel has been shipped pre-configured then once correctly connected the system will be operational. The controller should correctly cycle through each channel with no indicated errors.
Page 14: Relay Connections
Page 14 of 25 Relay Connection As standard the TOC-625 controller is equipped with two relay outputs. The function of these two relay outputs can be user configured and is discussed in a later section. The relays are rated to operate 4A non inductive loads.

Page 16: Adding Detectors Or Nodes
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.

1. Perform a complete new set up 2. Add or remove detectors from a system 3. Change the type of sensors connected to a system Then presuming the system is correctly installed and cabled the process would be as follows: 1.
Page 18 (installed). Then the alarm levels can be set in the following manner. From the TOC-625 SET UP REPORT it can be seen that each connected and installed detector or channel can have two alarm levels set. These can be different for each device. For example a two channel system for Methane and Carbon Monoxide may have Alarm 1 level for Methane at 20% LEL and Alarm 1 level for Carbon Monoxide set at 35ppm.
