SDC 101-1A Remote or Local Audible Tone and LED Annunciator for One Door

Ensure fast, reliable door status visibility where it matters most — at nurse stations, guard posts, or central security consoles. The Security Door Controls SDC 101-1A Remote or Local Audible Tone and LED Annunciator is a single-door annunciator that streamlines security monitoring and response. With a tri-color LED that displays precise delay and mode status and a selectable local or remote audible tone, staff can quickly assess and act on door events without checking the door itself.

Built for integration, the 101-1A works seamlessly with SDC Exit Check systems and operates on standard 12V or 24V DC power, making it easy to add to existing access control and surveillance infrastructures. Its compact wall-mount form factor reduces installation time and keeps control points neat at nurse or guard stations. Ideal for hospitals, correctional facilities and commercial properties, this annunciator helps reduce response times, improve situational awareness and tighten overall security monitoring.
