Connections
In order to carry out high voltage testing and resistance measurements, temporarily connect the
incoming and outgoing zone cables to each other using a 3-way connector block. Once all testing has
been carried out on the cabling, and ‘continuity & integrity’ has been proven, the SRM may be
connected and assembled.
Please remember that all high voltage testing must be carried out before the installation of the SRM
otherwise the electronics will be damaged.
Remember that the device at the end of the line must have its EOL signal activated using the relevant
EOL switch (Refer to DIL switch settings table on page 12). Do not use a resistor or capacitor (or
another manufacturer’s End of Line device) as the end of line, as this may prevent correct operation of
the zone.
Module Layout
The following figure shows the SRM layout. Terminals J1 thru J6 are used for all the field wiring
connections. DIL switch SW1 is used to select between 1x24V or 2x12V solenoid(s) and
DIL switch SW2 is used to configure the SRM (Refer to DIL switch SW2 settings table on page 12).
