Maximum Talkback Reply Distance
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.
IMPORTANT
The speaker is no better than your ears. If you cannot carry on a conversation at normal voice levels over the required talkback distance, then the talkback page equipment will not function satisfactorily.
Use common sense when mounting a talkback speaker. The speaker should be as close as possible to the area where talkback is desired. It should not be mounted close to or pointed at, noise producing equipment such as fans, air conditioners, machinery or compressors.
