reverse polarity or a short circuit. The red light will flash every time it sees a badge fire. A constant

pattern of four or five flashes may indicate there is a problem with the connectors on the cable.

To wire collectors

Note: Do not make any connections to components unless indicated by a step in the

procedure. Ensure that all bridge clips have been removed from the selected

punch-down block/collector unit.

1. Refer to the contractual floor plan schematic diagram and identify the concentrator location.

2. Refer to the contractual floor plan schematic diagram and identify all collector locations.

3. Verify that each collector cable for each collector site and the concentrator site has been

installed as indicated on the contractual floor plan schematic diagram.

4. Attach an RJ connector to each end of the collector cable.

5. Using the Weidmeuller Patch Check Plus test set or an equivalent model, perform the

following steps to verify straight through continuity for each collector cable run:

a) Plug one end of the cable into the receiver unit of the test set.

b) Set the reset switch on the receiver unit to the “On” position.

c) Plug the other end of the cable into the Transmitter unit of the test set.

d) Set the reset switch on the transmitter unit to the “On” position. All the red LED’s will

light followed by an audible squawk tone.

e) Touch the TEST button on the transmitter. After a short delay, the transmit #1 LED will

light with the corresponding #1 LED on the receiver scale

f) Touch the TEST button again to light transmit #2 LED with its corresponding receiver

#2 LED.

g) Repeat this process until all conductors in the cable have been verified for continuity.

6. Mark the collector cable as checked on the Installation Checklist.

7. For each collector perform the following:

a) For the collectors identified on the contractual floor plan schematic diagram as

LAST, set the UNTERMINATED/TERMINATED switch to the TERMINATED

position. For all other collectors, set the switch to UNTERMINATED.

b) Insert the RJ plug(s) into the collector receptacle(s) (either collector receptacle is

acceptable.)

c) Mark the collector as installed on the Installation Checklist.
