approximately 20 feet apart.
Good quality page audio will be
heard up to 30 feet in front of the
speaker.
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
5 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 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 7 and 8 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 7 gives guidelines for the number of
speakers per audio run.
Power Pair: The cable runs specified in Table 8 are
very important and
MUST
be followed for proper
operation of the one-way paging speakers.
