The green OK LED on the front panel indicates correct operation of the unit. This LED
extinguishes on failure as described above. When the OK LED extinguishes shutdown state is
indicated. In this state, all digital outputs turn OFF and the +24V supply turns off.
On processor failure, or on failure during start-up diagnostics, the unit shuts down, and remains
in shutdown until the fault is rectified.
The unit also shuts down if the battery voltage falls
below 10.8 volts. This is a protection feature designed to protect the battery from deep discharge
in case of extended period without supply voltage.
Note: During diagnostic testing, it is likely that the module will reset and restart. This will
affect the output signals.

Self Test Functions
6.2.1
Input to Output Reflection (105-1 only)
The unit will require re-configuration after SELF TEST. Ensure you know the
required operational configuration including system and unit addresses so that the
network can be restored after testing.
Remove the cover in the front panel, and set the DIP switches as shown below. Hold down the
