SYSTEM DESIGN
General
The 45 Ohm Talkback Speakers are designed to
be used with the Valcom "handsfree" talkback
control units. In combination with these units,
they will provide both loudspeaker and talkback
functions.
A standard Valcom talkback paging system is
made up of three basic components:
1. A talkback page control unit
2. Speakers (45 Ohm)
3. A power supply
Consult Valcom's VSP - Handsfree Talkback
Paging (Part # 947099) for detailed information on
selecting the control unit and power supply.
