To ensure a proper installation of the APS Custom, follow the guidelines below.
For the APS Custom Control Unit:
• Never install the unit in a damp area or where the unit may be exposed to
moisture or extreme fluctuations in temperature.
• Never install the unit in areas where the ambient temperature goes below 40
degrees (F) or exceeds 90 degrees (F).
• Connect the unit to the transmitter using the shielded RS232 type data cable
provided with your transmitter. Route the connections to keep them clear of
induced magnetic or electrical noise. The distance between the unit and
transmitter should not exceed 50 feet, or 15 meters. The data cable should
be connected securely to the APS Custom transmitter port on one end and to
the proper transmitter data port on the other. Please refer to Appendix D,
Wave Ware Paging Transmitter.
• Mount the unit and transmitter near a standard 110V AC power source.
The unit comes equipped with a 9V AC power jack. The power supply
included with the unit provides 9V AC at 780mA from a 110V AC source.
• Install the APS Custom as a wall-mount unit. Drill templates are provided
for the unit to assist the installer in properly placing the mounting screws.
• When mounting the unit on hollow walls or other similar materials, use
suitable fasteners. Plastic screw anchors are provided.
For the transmitter:
• Never install the antenna near or adjacent to telephone, public address or
data communications lines, or overhead power cables.
• Avoid running antenna cables adjacent to other cables.
• Avoid mounting the transmitter near telephone exchanges or computer
equipment.
• Always use 50-ohm coaxial cable between the antenna and transmitter.
WARNING: Coaxial cable used for television, satellite or CCTV
installations is normally 75-ohm and unsuitable for
connecting the antenna and transmitter.
• Avoid mounting the unit on or near foil-backed plasterboard, metal mesh or
wire-reinforced glass, metal sheeting, large mirrors suspended ceilings or
elevator shafts.
