INSTALLATION INSTRUCTIONS

HORN SPEAKER WITH AMPLIFIER

Use this product according to this instruction manual. Please keep this instruction manual for future reference.

MODEL NUMBERS:

SA-H5-B 8" HORN SPEAKER W/5 WATT AMPLIFIER
SA-H15-B 8" HORN SPEAKER W/15 WATT AMPLIFIER

GENERAL:

Horn speakers with built-in amplifiers are used for one-way voice paging, background music, and tone alerting in large indoor and
outdoor and/or noisy locations. Model SA-H5-B has a built-in 5 watt amplifier, and model SA-H15-B has a built-in 15 watt
amplifier. Both models have a built-in volume control. The horn speakers with built-in amplifier are used in the following manner.
Figure 1 shows a zone paging application used with Wheelock's Zone Page Control Module. The horn speaker can also be used to
provide single-zone paging when connected directly to an unused Central Office (C.O.) line port, which can be programmed to
function as a 600 Ohm Audio Page Port (i.e., does not require Talk Battery). See Figure 2.

NOTE: All CAUTIONS and WARNINGS are identified by the symbol

. All warnings are printed in bold capital letters.

WARNING: READ THESE INSTRUCTIONS CAREFULLY. FAILURE TO COMPLY WITH ANY OF THE
FOLLOWING INSTRUCTIONS, CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION,
INSTALLATION AND/OR OPERATION OF THESE PRODUCTS IN AN EMERGENCY SITUATION, WHICH COULD
RESULT IN PROPERTY DAMAGE, SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

See notes 1 and 2 below.

*NOTES:

1. Some telephone systems require that the C.O. trunk port (loop start) or C.O. line port be equipped with a trunk card, page card or

other equipment. Consult the telephone manufacturer's system manual for equipment or programming required.

2. If unused C.O. port requires talk battery to pass audio (most do) then a Wheelock Zone Control is required as an interface for

zoned paging systems. For single-zone paging a Wheelock PRM-150 Preamplifier with an RPS-2406 power supply is required as
an interface.

Figure 3 shows a horn speaker w/amplifier connected to a tone generator for telephone alerting or night ringing, with paging.

zoned paging systems. For single-zone paging a Wheelock PRM-150 Preamplifier with an RPS-2406 power supply is required as
an interface.

an interface.

2. The horn speaker w/amplifier can be used to amplify the tone of a telephone as shown in Figure 5. It can also be used to expand

the capability of 25 or 70 volt paging systems. Up to 125 horn speakers w/amplifiers may be connected to each transformer using
the 1/4W tap.

: Maximum capacity is 10 horn speakers w/amplifiers (See System Capacity below). If a PRM-

: Maximum capacity is 125 horn speakers w/amplifiers.

150 preamplifier is used, then maximum capacity is 150 horn speakers w/amplifiers.

SYSTEM CAPACITY:

For applications with a typical 600 Ohm source impedance such as a telephone system audio page port, a maximum of 10 Horn
Speakers may be used. Additional Horn Speakers (up to 150 maximum) will require the PRM-150 Preamplifier for correct level and
impedance matching.
