The 5 watt version will cover up to 3,600 sq. feet.
Depending upon the height of the installed
speaker, good quality paging will be heard up to
60 ft. in front of the speaker.
Pendant Speaker
:
The area covered by a pendant speaker is
determined by the mounting height. Refer to
Table 3 & 4 for speaker coverage.

Noise Level Definitions:
Quiet:
50-65dB.
This would include areas such
as waiting rooms or doctors' examination rooms.
Moderate: 65-80dB.
This includes areas such
as warehouses, shipping areas, or light
manufacturing.
Noisy: 80-90dB.
This includes machine shops
or heavy manufacturing.
Very Noisy: Greater than 90dB.
This would
include areas where talking to another person is
very difficult. Workers may be required to wear
earplugs.
NOTE 1:
In areas where the sound level
exceeds 100dB, consideration should
be given to using a code call unit
(V-9923B) for tone signaling instead
of using voice paging. In extreme
ambient noise, it is generally easier to
identify a tone code than to discern
speech.
NOTE 2:
Reverberant Areas - To increase the
intelligibility of paging in reverberant
areas, horns should be mounted
closer to the people being paged, in
effect, mounted at a lower height,
closer together and angled towards
the floor.
Speaker Cabling
All Valcom one-way amplified speakers
require 2 pairs to operate. Standard CAT
3/5/5E/6 telecom/ data cable may be used.
Existing telephone wire and feed cables may
also be used. Refer to Tables 5 and 6 when
planning a job.
Audio pair: The number of speakers looped
on the audio pair is not critical unless you
have a very large job. Table 5 gives guidelines
for the number of speakers per audio run.
Power Pair: The cable runs specified in Table
6 are very important and MUST be followed for
proper operation of the one-way paging
speakers.
