Repeater Installation
1.
Use of a single repeater is optional but may improve system performance when installed correctly. The
Repeater should be located closer to the device transmitters to rebroadcast messages to the Receiver. Use
the 15 Vdc power source provided in the Receiver to power the Repeater, or use a customer supplied non-
interruptible, Class 2, 15 Vdc power source. The most common method of powering the Repeater power is to
use the Repeater power terminal block J4 in the Receiver (see item 9 in Figure 21).
When device transmitters are on the opposite side of the building from the Receiver, the Repeater should be
mounted on the side of the building facing those transmitters. Mount the Repeater with its transmitter antenna
in the up or vertical orientation.
2.
The Repeater is attached to its mounting bracket with #10 x 1/2” taptite screws from its install kit (ref.
Figure 20 on page 28). The L-bracket is then attached to the outer wall of the building using appropriate
fasteners (customer supplied). If the Repeater will be exposed to the weather, attach the L-bracket to the
mounting surface inside a weatherproof enclosure. This enclosure is not required when mounting the Repeater
under a roof overhang and shielded from the weather.
The Repeater is only suitable for use in a non-hazardous location.
3.
Set S1 and S2 as desired (refer to Appendix B). NOTE: set all dip switches prior to connecting the +15 Vdc
power cable as the dip switches are only read during power up.
4.
Note the cover of the Repeater indicates the cord grip to be used for the cable connecting the Repeater to its
dc power source (item 5 in Figure 22). Remove the cover of the Repeater and set it aside.
5.
Slide the nut over the cable. Choose the correct size bushing and slide it over the cable. Dress the cable
jacket according to the dimensions in Figure 18. Insert the cable into the appropriate opening at the bottom of
the housing. Insert each wire into the appropriate terminal and tighten. Leave a small amount of slack in each
wire. Slide the bushing into the bottom of the housing. Hand tighten the nut.
6.
Connect the 2-wire dc power cable to the Repeater terminal block, white to +15 Vdc and black to GND (see
item 7 in Figure 22).
7.
Hand tighten both cable entry cord grip nuts to prevent water entry!
8.
To assure a water-tight seal between the cover and the enclosure, follow these steps:
a. Insert the four cover screws through the cover and then press on the retaining washers to hold the screws
in place.
b. Make sure that the cover gasket is free of dirt and debris on both sides of the gasket and that the inside of
the cover is clean in the gasket area.
c. Position the gasket into the cover groove, assuring that it is pressed fully into the groove and sitting
completely flat.
d. Assemble the cover onto the enclosure, tightening the screws in a couple of turns each. Using an
alternating ‘X’ pattern, continue to tighten the screws until they are all tight.
9.
The other end of the Repeater’s dc power cable connects to the Receiver’s +15 Vdc output terminal (ref. item
9 in Figure 21), or to a non-interruptible, Class 2, 15 Vdc power source.
