The PPM-AS is an uni-directional addressable condenser paging microphone, allowing to live announcement/play pre-recorded messages to any pre-assigned zones. The paging station has a gooseneck microphone, a push-to-talk button, zone selection keys and a monitor speaker. Buttons can represent a single zone or a group of zones and are easily defined in the software using a simple matrix selection. All buttons can be programmed with drag & drop features from the software and each button can be programmed for PTT (Push To Talk) or latching functionality.

In accordance with BS5839, the PPM-AS is monitored on RS485 communication protocol. The RS485 protocol allows daisy-chain up to 300M on a single CAT5 cable (FTP/STP) and makes each station easy to connect using standard RJ45 connectors and the PPM JB junction box (supplied with PPM-AS).
