4.5.4.3 Collector Wiring
The collector devices connect to the sensor network using modular interfaces to allow for testing of the
wiring before power is applied. It is recommended that installers are equipped with appropriate cable
testers to verify the polarity and validity of installed wiring.
There are two parallel RJ receptacles on each collector. This allows collectors to be chained together
from their assigned concentrator to the last collector in the chain. A key indication of connector
problems with the collector cable is the red indicator light on the collectors, which may indicate either
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.
