GENERAL INFORMATION

Sheet 1 of 5
The Tone Generator portion of the module provides a pleasant chime signal when used with existing or newly installed paging systems. It
C
is designed for use on the public telephone network or behind PBX and key systems that use interrupted or continuous ringing voltages
from 40-130VAC, 20-30Hz. It is also designed for use with telephone communications systems whose ringing voltages are from 18 to 30
Volts AC/DC or those that supply a continuous or pulsed contact closure.
The Tone Generator produces a single chime sound once every second. Both the tone and the sound level are adjustable.
The muting portion of the module can be used to control 3 paging zones. If there is an incoming call the module will switch off the
background music and generate a pleasant chime tone over the paging system. See Figure 1 below.
