The Tone Generator portion of the module provides a pleasant chime signal when used with existing or newly installed paging systems. It
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.

To power the TGM-300 a 24 Volt power source is required. Wheelock's EPS-2401 power supply will power the TGM-300. The unit is
intended for indoor use only
