A. Unpacking
After unpacking the unit, examine it for damage that may have occurred in transit. If the equip-
ment has been damaged, do not attempt to install or operate it, file a claim immediately with
the carrier stating the extent of the damage. Carefully check all envelopes, shipping labels and
tags before removing or destroying them.
B. Installation Of Subset, Wall Station and Indoor/Outdoor Station Enclosure
(See Figure 1, 2)
The remote subset unit for panel mount and desktop stations, the wall mount, and the indoor/
outdoor wall mount SelectFone stations use the same enclosure to house motherboard, plug-in
speaker amplifier, power supply etc. Only the front enclosure covers are different. The enclosures
are designed to be mounted on a flat surface with user-supplied hardware. As the locations of
SelectFone stations vary with each installation, these enclosures are not provided with conduit or
cable openings. To install the SelectFone station enclosure, proceed as follows:
When the wall station is to be used in wet locations which require the use of the indoor/outdoor
station enclosure which is rated Type 4X, Type 12, Type 13 and IP66, an equivalently rated cable
gland or conduit hub must be used when connecting to the indoor/outdoor station enclosure.
1. Plan all the wiring and cable routing with the following guidelines in mind. While the distance
between stations is not critical, the total power cable length should not exceed 5280 feet (1
mile) for 120VAC systems. The SelectFone system cable can be installed in cable trays or
conduit. The maximum outside diameter of the five channel system cable is 0.65” (16.51
mm) and that of a single channel system is 0.43" (11 mm). Select the proper conduit size and
make no more than two bends for each length as the excessive force required to pull the cable
through may damage the insulation.
2. Determine the mounting location. The suggested mounting height for a wall station enclosure
is 54" (137 cm) up to the center line of the enclosure. Ensure that the mounting surface is
flat.
3. Remove the cover of the remote subset or wall mount SelectFone intercom station by remov-
ing four screws. Loosen the two screws and unplug the ribbon cable connector at CN1. This
cable makes the connection between the handset amplifier board and the motherboard. Set
the cover and screws aside.
4. The stations are shipped with the motherboard, power supply, and speaker amplifier installed
as shown in the Figure 1. The best location for conduit or cable holes is the left half of the top
or bottom wall or the left wall of the enclosure 1-3/4” from the bottom. Do not use the right
half of the top wall and right wall to avoid interference with the power supply and speaker
amplifier. Loosen the two screws that anchor the power supply to the standoffs on the bottom
of the enclosure, unplug, and lift out. Similarly remove the speaker amplifier. Loosen the four
screws at the four corners that anchor the motherboard to the standoffs mounted on the bottom
of the enclosure and remove. Save all the hardware to reassemble the unit. Drill or punch the
necessary conduit or cable openings in the empty enclosure.
5. Place the rear of the housing against the mounting surface. Using the four mounting holes
located in each corner of the enclosure as a template, scribe mounting hole locations on the
mounting surface.
EQUIPMENT DAMAGE HAZARD
To avoid damage when drilling, ensure that both sides of the mounting surface are clear of any
parts or wires. Drill the holes only through the desired surface.
