3.2 WIRING – STANDARD
3.2.1 Dropped / Hard Ceiling Installation
Refer to
Figure 10
for installation diagram.
1. The top plate in the housing can be lowered for ease of installing the field wiring.
Pull the spring latch on the plate away from the housing to release the plate and
then lower the plate down.
2. Feed the field wiring (data, power, video, and alarm inputs) through the housing and
then through the cable clamp on the top plate.
3. Install the 24Vac power wires, data wires, and alarm wires on the correct positions
on terminal strip TB1 and TB2 in the housing. Refer to
Figure 3
. The terminal strip is
labeled to show the function of each position.
NOTE:
Do not connect the data cable shield at the terminal strip.
The terminal strip accepts 18-24AWG wire. If larger or smaller
field-run wire is required, an 18-24 AWG wire must be spliced
onto the field wire for insertion into the terminal strip.
a. Flip up the tab on the terminal strip.
b. Strip the insulation on the wire back approximately 7/16”.
c. Insert the wire fully in the hole on the terminal strip to ensure a good contact and
to ensure it does not short to adjacent wires.
d. Push the tab down to secure the wire.
4. Connect the video coaxial cable to the BNC connector in the housing. The installer
must supply the mating BNC connector.
5. Feed the excess cabling from the terminal strips back through the cable fitting and
tighten the cable clamp.
6. If this is the last dome in a daisy-chain wiring loop, the receive and transmit
communication lines must be terminated. All intermediate domes must be
unterminated. If this is the only dome on a data line, the receive and transmit
communication lines must be terminated.
Install Jumper W1 on pins 1 and 2 (terminated) to terminate the data.
Install Jumper W1 on pins 2 and 3 (unterminated) to unterminate the data.
Install Jumper W2 on pins 2 and 3 for all domes.
7. For standard HD6 2-wire communication, install Jumpers W3 and W4 on position 1
and 2 for all domes.
