Add Paging and Loud Ringing with
Background Music to Any Phone System
The PA-30 can directly drive up to thirty (30) 8 ohm
paging speakers or fifty (50) 70 volt or 25 volt
paging speakers. This small and light weight
chassis design is possible by utilizing new amplifier
technology that is 300% less inefficient than old
designs competitors use. High efficiency means
much less heat disipation, smaller size, higher
reliability, and lower cost.
The PA-30 provides loud ringing and paging to
electronic key systems, 1A2 Key systems, PABX's
as well as No-KSU phones and multi-line phones.
Paging is accomplished by connecting the PA-30 to
a paging port or unused telephone line input (trunk
port) of nearly any phone system.
The PA-30 will also generate adjustable loud ringing
from a ringing analog line or from a dry contact
closure. Either a loud electronic warble, or one of
three other soft chime sounds may be selected. An
external "night transfer" switch can be added to turn
loud ringing on or off in night bell applications.

  • Page 6 (which will actually provide 30 watts of power). When using 70 volt speakers on the PA-30, each speaker actually gets only ¼ as much power as the selected tap. To get 1 watt of power into a speaker, use its 4 watt tap. The sum of all the speakers’ power taps should not exceed 120 watts (which will actually provide 30 watts of power).

  • Page 7: Operation

    If paging from a phone system’s unused Telephone Line Input (Trunk Port), FXO, or dedicated analog phone, DIP Switch 1 must be turned ON so the PA-30 will provide the necessary 40V DC of Talk Battery. To page, either access that Trunk Port or go off hook on the analog phone. Loop current will be detected and activate paging.
