Model CB195-xxx Flush-Mount RF Call Box
The Model CB195-xxx provides the same functionality as the CB193-xxx, but is typically installed
where a flush-mount unit is needed, such as in a wall or stanchion. The major difference between the
two models is the antenna configuration.
1. When mounting in a GAI-Tronics Model 234 Series Stanchion or for flush-mount installations, the
supplied back box must be used to mount the Model CB195-xxx RF Call Box. Remove the front
panel assembly (six screws) and mount the back box to the structure using the appropriate hardware.
Refer to Figure 9 and Figure 10. The cutout dimensions are 10.1 H
× 7.6 W inches (255.6 × 193.0
mm).
2. For conduit/cable installation of external power, route the cable through the opening on the bottom of
the back box.
3. Attach the appropriate external antenna to the RF Module by routing the connectorized antenna cable
through the rear of the back box.
4. When applicable, install the Model 190-001BB Back-up Battery Kit and/or the Model SPK100 Solar
Charge Regulator in accordance with the included instructions. Connect the black and red wires of
the wiring harness provided to the battery connectors: positive (+) to the red and negative (−) to the
black. Refer to Figure 4.
5. To connect an external dc power supply, strip the power supply connection wires and attach the
positive (+) to pin 1 and the negative to pin 2 of the connector assembly that is plugged into TB1 of
the PCBA located on the front panel. Refer to Figure 4 on page 31.
6. Inspect the jumpers to ensure the Call Box is configured to suit your application. See the “Hardware
Configuration” section on page 38 for details.
7. Program the Call Box. See the “Programming and Set Up” section on page 48 for details.
NOTE
It is extremely important to dress all cables to prevent the power and RF module
connection cable from touching the external antenna cable with the front panel closed. Failure due
to improperly dressed cable may result in RF induced noise during transmit.
8. Attach the Call Box front panel to the mounting flanges of the back box using the six supplied
#10-32 security screws and six black flat washers.
