Bridge-clips are used to connect left-side pins to the right-side pins, which are wired to the collector
unit. If patching of sensor inputs is required, jumpers can be used from any sensor wire-pair on the left
to any collector wire-pair on the right.
Make sure power is not supplied when connecting components.
Punch-down Block
To connect the sensors to the punch-down block:
For connecti ng the sensor wires to the punch-down bloc k, refer to the Punch-down Block Organization
Chart for the location each wire should be connected on the block.
1. Remove all bridge clips from the punch-down block.
2. Referring to the Punch-down Block Or gani zation List to make sure each sensor wire is
connected to the correct position on the punch-down block, connect the sensor wire-pairs to
the appropriate punch-down block pin-pair positions using the punch-down block tool.
3. Check isolation.
This is necessary because in the course of interconnecting many sensors to a collector, it is not
uncommon to make contact with a sharp metal edge, ganged knockout box, or electrical
ground with one of the conductors. It is critical, however, that such accidental connections be
located and cleared before applying power to the system. The effect of these accidental
connections can range from mild to severe. In many cases, erratic behavior may be noted. In
