The Speaker Amplifiers are used in the following manner. Figure 1 shows a zone paging application used with Wheelock's Zone
Page Control Module. The Speaker Amplifier can also be used to provide single-zone paging when connected directly to an unused
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.

(See Note 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 manufactures 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 speaker amplifier connected to a tone generator for telephone alerting or night ringing, with paging.

Figure 4 shows the same tone generator and speaker amplifier activated by a common audible.

The speaker 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 speaker amplifiers may be connected to each transformer using the 1/4W tap.
