3.3 WIRING – UNSHIELDED TWISTED PAIR (UTP) OPTION
3.3.1 Dropped Ceiling / Hard Ceiling / Pendant Dome Installation
1. Dropped/Hard Ceiling Domes: 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.
Pendant Domes: Route the field-run wiring through the cable hole in the top plate
(cable enters hole on back side of plate, opposite circuit board).
2. Dropped/Hard Ceiling Domes: Feed the field wiring (data, power, video, and alarm
inputs) through the housing and then through the cable clamp on the top plate.
3. Connect field wiring. Refer to Figure 16 .
a. Connect the 24Vac power wires at TB2. Terminal Strip TB2 accepts 18-12 AWG
wire.
i. Loosen the screw on the terminal.
ii. Strip the insulation on the wire back approximately 1/4”.
iii. 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.
iv. Tighten the screw.
b. If using the UTP wiring option, connect the twisted pair for data at TB1 (RX+ and
RX-) and connect the twisted pair for video at TB3 (+ and -).
Do not connect the data cable shield at the terminal strip. Terminal strips TB1
and TB3 accept 18-24 AWG 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.
i. Flip up the tab on the terminal strip.
ii. Strip the insulation on the wire back approximately 7/16”.
iii. 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.
iv. Push the tab down to secure the wire.
