DEVICE DESCRIPTIONS

5.1.5 2-Channel Paging Station Module (NRS 90215)

This 2-channel audio input module is meant for the connection of DPC 4000 Series paging consoles. Each of the two input channels provide RJ-45 sockets allowing the connection of up to 4 paging stations plus paging station extensions per input. The microphone terminals are interconnected via 6-conductor parallel cables. The module can be installed in slot 1 and slot 2.

Next to the electronically balanced audio input, each input connector provides a serial RS-485 interface port and the power supply connection for the paging stations (see also: pin-assignment of the RJ-45 connector). The paging stations' power supply employs an electronic, programmable fuse, through which the maximum output current can be matched to meet actual system accommodations. This prevents the entire installation from malfunction, in case of short-circuit occurring in a single paging station only.

Input channels can be switched separately onto the monitor bus and you can monitor the audio signal via headphones or loudspeaker, either which is connected to the monitor output. Automatic pilot tone surveillance of the entire input stage is integrated as well. If necessary, retrofitting the audio inputs with transformers is possible.

Note: When connecting several paging consoles to a single input, please keep in mind that line interruption or short-circuit can cause malfunction of several or even all paging stations of that specific line. In emergency alert installation, connecting security-related consoles to individual inputs is therefore of major importance.
