INSTALLATION
CAUTION: These units must be properly and
securely mounted to a supporting structure
capable of sustaining the unit weight. Use care
when selecting mounting hardware (not
supplied) for installation; the mounting surface
and unit's weight should be carefully considered.
4.1
Pipe Mounting
1. The Ceiling Mount (LTC 9543/00) is used to mount
the unit to the ceiling.
2. Attach a safety cable to an appropriate point on the
ceiling.
3. Feed the cables through the ceiling mount and
fasten the mount to the ceiling using 4 fasteners
(FIGURE 1). Allow enough cable for the length of
the pipe + 1m (3ft). 10mm (3/8in.) bolts/studs are
recommended. Bolts should be secured with nuts,
washers, and lock washers. Surface fasteners, and
surface should withstand 270kg (600lb).
4. Each end of the pipe should be threaded to a
minimum length of 25.4mm (1in.). Pipe thread
standards which may be used are as follows:
American National Standard - NPT.
British Standard - BSP.
5. If metric pipe thread is used, an adaptor is required
at each end of the pipe.
6. Feed the cables through the pipe and the mounting
cap.
7. Make the electrical connections to the supplied
mating connector. (See FIGURE 2).
NOTE:
Either of the power wires can go to either of
the specified pins on the mating connector. In
multiple camera installations, connect the wires
to the same connectors to ensure proper
camera phasing.
a.
Connect the low voltage power leads to
the 24VAC pins. Connect one heater
power lead to the H pin and the other
heater power lead to 24VAC Pin-1.
Tighten all screws.
b.
Connect the video lead to the BNC
connector located on the top of the
housing.
8. Connect the mating connector securely to the
connector on the connector plate.
9. Securely tighten the mounting cap onto the pipe to
approximately 44N.m (30ft lb).
10. Torque the pipe into the ceiling bracket to
approximately 44N.m (30ft.lbs).
11. If a significant length of pipe is used, support the
pipe with braces or guy wires to prevent the
swaying motion of the unit from being noticed on
the video display.
