TIPs
•
For
data
, you have the choice of
connecting UTP for RS-422 or
connecting STP for RS-485.
- If you are installing RS-485,
float the shield at the dome and
ground it at the keypad.
- If you are daisy-chaining domes,
connect the incoming and outgoing
cables to the MAIN terminals.
•
For
video
, you have the choice of
connecting UTP or coaxial.
- If you are installing coaxial video,
use only crimp-on BNC connectors.
•
For
power
, feed the cable over the top
of the upper bracket,
never through the
center
. Power is not polarity sensitive.
•
For
alarms
, use dry contacts.
•
For
relays
, use a maximum operating
voltage of 30 VAC, 30 VDC at 0.5 A.
•
Because of space constraints, if you are
installing more than five alarms and/or
relays, use a multiple-conductor cable
instead of individual single-pair cables.
•
If heaters are present, route all cables
away from them.
