Before You Begin

To ensure a smooth and successful installation,
observe the following requirements.

General Requirements

• Have electrical work comply with latest national
electrical code, national fire code, and all
applicable local codes and ordinances.
• Coordinate work with other trades to avoid
interference.
• Verify existing site conditions and coordinate
with the owner's representative and appropriate
utilities as required.
• Obtain copies of all related plans, specifications,
shop drawings and addenda to schedule and
coordinate related work.
• Thoroughly review the project to ensure that all
work meets or exceeds the above requirements.
Bring alleged discrepancies to the attention of
the CCTV Project Coordinator.

Mounting Requirements

Structural members: Verify that ceiling members
can support the camera dome and mounting
structure, if used.
Weight: 2.5kg (5.5 lbs)

Cable Requirements

Data cables: Table 2 shows cable requirements
for SensorNet and Manchester networks. For more
information about communication protocols and
cable networks, see Communication Protocols and
Cable Networks, 8000-2573-19.

* Power, data, and video cables can be ordered
separately or within a composite cable that can be
ordered in various lengths. Plenum-rated cables must
be used in indoor ceilings used for environmental air
return (called "other air space" in the National
Electrical Code). Order parts through your distribution
network.
Note: If you order cable from an outside source, wire
colors may be different.
** The RS-422 Simplex connection only uses a single
twisted pair allowing the dome to receive only.
RS-422 transmit from the dome is not supported.
*** Belden 88760 (plenum), or Belden 8760 cable (non-
plenum) cable is recommended. Plenum-rated cables
must be used in indoor ceilings used for
environmental air return (called "other air space" in
the National Electrical Code). Order cable
directly from Belden by calling 1-800-235-3361.

to or in the same conduit as line voltage
mains power.
Power cables. Make power cable lengths as short
as possible to minimize the affects of low line
voltages and outdoor cold temperature perform-
ance. Maximum cable length between a Class 2
LPS (low voltage) ac source, such as a J-box, and
the dome depends on the ac line voltage. See the
tables below for maximum cable lengths based on
the worst-case low line voltages.
The line voltage must not go below the voltage
shown for the dome to be able to power up and
operate at the corresponding distances shown.
Typically cable distances are used that provide a
15% margin between nominal and low line
conditions. For example, if the nominal voltage
measures 120Vac, restrict the cable length to the
distance for 0.85 x 120 or approximately 100Vac.
