The PPM-AS is a unidirectional directional condenser paging microphone that allows live announcements/playback of pre-recorded messages in any pre-assigned zone. The paging station features a gooseneck microphone, a push-to-talk button, zone selection keys, and a monitor speaker. The buttons can represent a single zone or a group of zones, easily defined in the software via a simple matrix selection. All buttons can be programmed with drag-and-drop functions from the software, and each button can be programmed for PTT (Push-to-Talk) or lock function.

According to BS5839, the PPM-AS is monitored on RS485. The RS485 communication protocol allows chaining up to 300m with a single CAT-5 (FTP/STP) cable, and facilitates connecting each station through standard RJ45 connectors and the junction box (supplied with PPM-AS).
