*NOTE:
1. 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 4 shows the same tone generator and horn speaker w/amplifier activated by a common audible.

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.
