SECTION 3:
WIRING THE HOUSING
3.1 INTRODUCTION
The field wiring for an indoor HD6 is connected at a terminal strip in the housing or
pendant dome. The field wiring for an outdoor HD6 is connected at a CPC connector
(J2) or to fly-leads on the housing. Refer to the information specified in the installation
instructions for wiring connections.
3.1.1
Power
Each camera assembly or scan requires a 24Vac power supply @ 1.1A measured at the
dome.
The following table shows the wire gauge required for maximum distances to maintain
24V ac ± 10% at the dome. These wire sizes and distances represent one power source
for one HD6.
