Punch-down Block
To connect the sensors to the punch-down block:
Note: Connect no more than four RF sensors to a Collector. Up to 24 sensors total can be
connected to a Collector.
For connecting the sensor wires to the punch-down block, 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 Organization 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
