Installation

The PA430 has been designed to accommodate a wide range of mounting
and aiming requirements.

Mounting to wall, ceiling or to electrical boxes is accomplished without the
common requirement of adding a steel plate to the base. Bonding straps
may be used for mounting to beams. All mounting holes are knocked through
only as needed, preserving a seal in the remaining knockout areas.

Wiring is enclosed within the product base, providing physical protection of
wiring and personnel.

The mounting assembly provides three means of adjustment, allowing the
horn to be oriented for any coverage pattern desired. Adjustment is
accomplished with nuts that require minimal torque to maintain horn position
and may be tightened by hand.

During installation, after punching out the desired attachments, the base
and horn are loosely secured with one screw. This leaves hands free to
wire nut the product zip cord and feed wiring together. After tucking wire
connections into the electrical box or base, install remaining screws.

Transformer Model (PA430T)

A transformer and power selector switch are installed in the rear housing.

The level of the PA430T may be adjusted by moving the switch setting (see
Table 2) using a coin or screwdriver; turn clockwise to increase the power.
Since the same switch and transformer are used for either the 100 volt,
70.7 volt or 25 volt line, the power setting depends upon the amplifier output
that is used, 100 volt, 70.7 volt or 25 volt.

CAUTION:

 When connected to a 100 volt or 70.7 volt line, do not use the

switch settings marked “

DO NOT USE

,” as this may result in excessive

power driving the PA430T.

Low-Frequency Driver Protection

For proper system operation, program information should be highpassed
at 300 Hz or higher with at least a 6 dB per octave slope filter. This is best
accomplished before the power amplifier using a low-level crossover;
however, protection of amplifier and paging projector may alternately be
accomplished using a capacitor in series with the projector. Table 1 gives
values for such protection capacitor. Polyester capacitors are recommended,
but non-polarized electrolytic or two series back-to-back connected
electrolytics, each of twice the value shown, may be used.
