9. COLLECTOR WIRING
The collector devices connect to the sensing 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, either reverse polarity or a short circuit, is the red indicator light on the collectors. The red light
will flash every time it sees a badge fire. A constant pattern of 4 or 5 flashes may indicate there is a problem
with the connectors on the cable.
9.1 Collector Wiring Steps
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 a RJ connector to each end of the collector cable as shown in Table 10-1.
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.
NOTE:
Do not make any connections to components unless indicated by a step in the procedure. Insure
that all bridge clips have been removed from the selected Punch-down Block/collector unit.
