Paging, Classroom AV and Emergency Communications:CONVERGENCE!!Communications:


CONVERGENCE!!Together?(efficiency)


What Does it Look Like?

A “Convergence” Example …

CM 3000

32W Amplifier

CM‐3000

4‐port network switch4 analog audio inputsBi‐directional streaming audioMi h iMicrophone inputDevice control (Serial, IR and GPI)

(CM‐800 and CM‐800S)

Power Requirements

Distributed amplifiers require power back‐up or POE. Variable power needs f lifi k POE h ll i B t l bl !

3rd Party POE Midspan Injector (e.g., Tycon)

of an amplifier makes POE … challenging. But solvable!

3 Party POE Midspan Injector (e.g., Tycon)o Roughly $550 for 16‐port unit

Calypso PD‐20W Power Extractoro Local power until power loss is detectedo Switch to POEo Maintain 20W

Why IP‐based Paging? Flexibility …

Unlimited “zone” creation. In the world of IP audio, a zone ll f ddis a collection of IP addresses.

Unlimited bell tones … which are standard WAV filesUnlimited bell schedules, to varying zones with varying tonestonesStream ANY audio message to ANY end point

Why IP‐based Paging? Savings …

No additional network investmentSmall additional classroom AV investmentSmall “head end” investmentRetain hallway amps and speakers (renovation)Eliminate redundant systems and installation labor
