The programmable relay card adds flexible control and signaling capabilities to PA and communication systems. Designed for security-critical environments, it enables customized functions such as alarm activation, fault indication, and mandatory call routing. Each relay can be programmed individually, for example, to operate as an emergency power relay in case of power failure.

Additionally, direct relay control via intercom station buttons is supported, allowing for fast and targeted responses. The current status of each relay is conveniently displayed on the system screen, facilitating system checks and maintenance.

Up to two relay cards can be used per system. A jumper allows the user to select between special function mode and amplifier mandatory-call mode.
