IGD TOC-625-MCP User manual

Auto Setup Table 1
Relay 1 and Relay 2 on the TOC-625-Micro are set to be normally energised, de-energising on alarm or
power failure.
The TOC-625-Micro can FIND up to 10 devices. These can be any mix of gas detectors and up to 2 output
nodes
The TOC-625-Micro can FIND up to 4 addressable relays on 2 output nodes. Relay nodes supplied with
TOC-625-Micro need to be addressed as follows and will operate according to the following table.
Node Relay Address
Relay 1 Relay 2

Note that mutable relays re-energise on second alarm.

GAS DETECTION SYSTEM International Gas Detectors
The control panel should be located outside the
area where the detectors are located so that it is
not necessary to enter to the area with a gas alarm
to reset or check the controller.
For detector locations refer to IGD document
BS023 Siting Gas Detectors. This is available from
the downloads area of our website.
Detectors are supplied pre-calibrated. If it is
required to check or demonstrate operation, test
gas kits are available from IGD
Note Alarms Levels and Types Are Fixed and Cannot be Adjusted
TOC-625-MCP is a multi-channel detector controller in an easily installed and implemented small
format package using pre-made plug and socket cables. The system can be used with the Tocsin
Addressable range of detectors or I/O modules listed in the auto setup table. The use of pre-made
cables means there is very little installation required, reducing cost and enhancing safety.625
Micro has a unique Auto Setup Function.

After the start up cycle the Setup Wizard is displayed and RUN option will be available for 10
seconds. Press the button during this period and the TOC-625 Micro will search for connected
detectors and relay nodes. Based on the devices found the controller will set itself up based on
table 1. No operator intervention is required. Gas channels will be automatically configured based
on the devices found. Need to add or remove a detector or node? Just make the physical changes
and select the RUN option again on power up

Once fully installed the TOC-625 controller will continuously monitor connected
gas detectors and sensors and compare current values with any set alarm
thresholds. The display will cycle to display each channel in turn.
