Applications
The 45 Ohm talkback speakers are designed to be
used with "handsfree" talkback control units. In
combination with these units, the speakers provide
both loudspeaker and talkback functions.
Environment

Power Requirements
None
Coverage
The distance you can be away from a speaker and still
have good talkback depends on the type of speaker
and amb ient noise level. In a typical office
environment, these speakers will cover approximately
600 square feet (Talkback from 25').
Remember: 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
talkback page equipment will not function
satisfactorily.
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.
Limitations
One talkback speaker maximum per zone when
used with the DL-24A System
800 feet maximum cable length to speaker
NOTE: Do not split pairs to speakers
Do not use talkback in noisy areas (80dB or
greater)
-20 to +55 Degrees C
0 to 95% non-precipitating
