The trend towards IP-based paging systems, where audio is decoded at network end-points in support of school paging, bells, intercom and emergency communications, creates a need for POE support of networked amplifiers.  Otherwise a school power outage eliminates paging and other emergency alert and communication functions.  Whereas typical POE devices draw relatively low, fixed power levels, amplifiers require higher power levels that vary with the application (bell volume as opposed to emergency evacuation instruction volume) and the audio signal itself.  This requirement is unsupported by nearly all standard POE components.

Designed for use with any qualified, 3rd party POE MidSpan Injector, the Calypso PD-20W is a compact product designed to support variable POE requirements and network connectivity for Calypso amplifiers, including the CM-3000, CM-800 and CM-800S.  Installed as a bridge between the POE cable and the network endpoint, the PD-20W breaks out both network and power signals from the incoming cable, sending them on as needed for Calypso amplifier support.  In addition the unit offers pass-through power from a local 12VDC power supply, for amplifier support when POE is not required, and automatically and instantly switches to POE power when power loss is detected.
