3.3 WIRING – UNSHIELDED TWISTED PAIR (UTP) OPTION, CONTINUED
c. Connect the alarm wires on the correct positions on terminal strip TB1 in the
housing.
d. Dropped/Hard Ceiling Domes: Feed the excess cabling from the terminal strips
back through the cable fitting and tighten the cable clamp.
e. Pendant Domes: Take up any excess slack in the field wiring and tape the
wiring together on the back side of the plate as close to the cable holes as
possible so it does not interfere with the rotation of the scan.
4. 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. Refer to the jumper table in
Figure 16 .
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.
5. Jumpers W3 and W4 define the type of cabling (UTP option) being used for video
and data. Refer to the jumper table in Figure 16 .
6. If the UTP option is used, DIP Switch SW1 must be set. The switch setting is
determined by the cable length between the video device (e.g. monitor) and the
HD6. Use the lowest switch setting possible for the cable distance. For example, if
the UTP cable run is 900 feet, set switch SW1-2 (600-900 feet) ON.
• Make sure only one switch is set to ON.
Refer to the table in
Figure 16 .
•
If an active video receiver (e.g. NVT Model NV-652R) is
used at the monitor end, set all the switches to OFF.
If the video compensation is not strong enough at this
setting, set switch S1-1 to ON. Ensure all other switches are
OFF.
