14) Talkback systems often cost less than one-way systems. This is especially

true when the majority of zones only contain one or 2 speakers. Up to 2 talkback

speakers may be direct connected to the Class Connection V-TCM or XP-TCM12

outputs without the need for amplifiers or power supplies. If a talkback solution is

acceptable, it is wise to evaluate systems that only require one way paging using

both one-way and talkback speakers in order to determine the most cost effective

solution.

15) If you plan to use our speakers in an existing, or non-Valcom enclosure, be

certain to choose speaker models that can be disassembled. Some speakers,

like the V-1021C, cannot be removed from their grille. V-C806PKs are often a

good choice as they attach to their grille via a removable bolt.

16) You may want to consider adding a V-1092 Volume Control to each one-way

zone that has more than 4 speakers. This will allow convenient volume

adjustment for the entire zone.

17) You may want to consider adding a V-9933A Noise Sensing Volume Control

in areas where the ambient noise level fluctuates (Cafeteria, Gymnasium). The

V-9933A automatically adjusts the speaker volume based upon fluctuating noise

levels. The V-9933A may not be used with continuous program material like

background music.

18) In high paging traffic applications such as hospitals or car dealerships,

multiple V-9964 Stacking Feedback eliminators may be used to allow up to 8

pages to be stacked simultaneously and played in sequence.

19) VoIP (voice over IP) may be integrated with the MultiPath intercom in

numerous ways to provide one way or talkback paging through a VLAN. This fact

allows qualified integrators to design MultiPath intercoms spanning multiple

facilities using network connectivity. Contact tech support to discuss your

particular application.

20) When utilizing V-RCA remote card adapters, account for:

a) the additional power required by the V-RCAs

b) the additional racks and ribbon cables required at IDF locations

c) a card slot position for each V-RCA

d) 19” racks for IDFs (if required)

e) V-CIO Clock relay boards for each remote IDF correcting clocks.
