available I/O Nodes any 4-20mA
Device such as pressure or
temperature transmitters, read
these back to the control panel
as any other detector and set
alarms as required.
Connect to detectors and nodes
using 4 core 1.5mmSQ CY style
cable or FP200 style cable as
appropriate. Cable screens
should be terminated as
indicated
Each I/O Node counts as one
device and can be used to
interface to analogue devices
and provide additional relay
outputs where they are
needed to control items such
as beacon-sounders,
solenoids or interfaces to fire
panels. Depending on
loading external power may
be required.
Gas detectors count as one device,
there can be any mix of gas detector
types on the highway. For example
Flammable Gas Detectors, Carbon
Monoxide, Oxygen etc.

Main power connections should only be made by a qualified electrician. Mains power should be fed via a fused
spur.
The following information shows the main electrical connection points labelled as points 1, 2 and 3. These
points are referred to in the manual supplied. When installing ensure you have the full manual available. This
page is also supplied inside the TOC-625 enclosure as a quick reference for site engineers. If you do not have

If the gas is still breaching the
alarm threshold it will not be
possible to reset the alarm
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. Normally the backlight will be switched off.
In the event of alarm or fault, CALL FOR SERVICE.
The owner operator is not usually a gas engineer or competent person
as defined by Health and Safety guidelines. If there is any doubt call
your service company and get it checked.
