LTC 9449 Series Instruction Manual Installation
4INSTALLATION
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.
4.1Pipe 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 pipe and mounting cap.
7.Make the electrical connection to the supplied mating connector. (See FIGURE 2).
NOTE: On both 24VAC and 12VDC units, either wire can go to either of the specified pins on the mating connector. In multiple camera installations using 24VAC units, connect the wires to the same connectors to ensure proper camera phasing.
a.Connect the 24VAC or 12VDC power leads to the 24VAC pins and tighten 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).
EN 8
10.Torque the pipe into 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.
