The DCN-15A analogue subsystems module is a compact 15-channel digital interface converter into analog communication lines and discrete control lines and vice versa, for connecting a loud warning power amplifier or receiving a fire alarm system command to start a warning.
The module contains 15 bidirectional analog line interfaces, 60 discrete bidirectional control lines and an E1 digital interface for connection to the DCN control panel.
The DCN-15A allows you to build a multichannel loudspeaker paging system with up to 15 channels, a maximum of eight zones per channel, using power amplifiers and relays for switching loudspeaker zones. It is also possible to connect up to 8 discrete control lines for each analog interface, up to 60 for 15 interfaces, which are used as inputs, for example, to connect alarm and automation systems through a “dry contact” or outputs to control external devices and connect relays for switching alarm and automation devices.
The DCN-15A module is good for applications where you need to build a large multi-zone public address system or accept multiple dry contacts to trigger an alarm.
The DCN-15A fits into 19 ”telecommunication cabinets or racks and is 1U high. To connect analog and discrete lines, E1 lines, the DCN-15A module is equipped with up to 4 connection cables, which are installed on a DIN rail.
The front panel of the DCN-15A contains an indication of the state of the subscriber interfaces, the E1 line, the state of the DCN-15A itself and the health of the power supply circuits for monitoring and evaluating the operability.
