3.2.1.1 PPM-AS Paging Console
PPM-AS is an unidirectional addressable condenser paging microphone for IDA8 system. In
accordance with BS5839, it is monitored by using the RS485 protocol over STP CAT5/6 cable, and
transmits both audio and power from the paging console to the system units. The PPM-AS has 8
zone buttons with a sleek gooseneck microphone, providing durability and aesthetics in a slim,
stable chassis.
PPM-AS enables live announcement to any pre-assigned zones (an optional PPM-SP hardware
version also allows for broadcasting the pre-recorded messages). The paging station has a
gooseneck microphone, a push-to-talk button, zone selection keys and a monitor speaker. Buttons
represent a single zone or a group of zones and be easily defined in the software using a simple
matrix selection. All buttons can be programmed from ATEÏS Studio software and each button can
be programmed for PTT (Push To Talk) or latching functionality.
In addition to the zone LEDs, “Hold” and “Busy” LED signals make PPM-AS an extremely user-
friendly paging console. Thanks to the cardioids polar pick-up pattern, the unidirectional condenser
microphone ensures the high-quality and directive signal pick-up with minimal interference from the
surroundings.
The RS485 communication protocol allows daisy-chain wiring up to 300m on a single CAT5/6 cable
(FTP/STP) and makes each station easy to connect by using standard RJ45 connectors. The
junction box supplied with PPM-AS allows multiple peripherals such as PPM-AS, CD8-AS, CD16-
AS, and URC-15AS to be cascaded with the distance of up to 300m between a peripheral and a
junction box, and up to 10 peripherals can be connected via junction boxes on one processor. In
addition, the junction box can be powered from the processor or 24VDC local power supply.
