Bogen CA10A Call-In Switch, Designed for use with the PI35A, SI35A and MultiGraphic Paging Systems, Aluminum

Enable dependable, one-touch call-in communication across classrooms and staff areas with the Bogen CA10A Call-In Switch pro wall plate. Designed specifically for Bogen intercom and paging systems, this aluminum two-position, rocker-type switch (single-pole, normally open) activates the corresponding annunciator lamp and call-in tone at the room selector panel and holds the call until the operator acknowledges it—ideal for school communications, facility monitoring and security response. The CA10A leverages SCR holding circuits to drive annunciator signals and LEDs on SBA-Series room selector panels and is fully compatible with PI35A, SI35A, MultiGraphic Series 115B/2223/2233 and Multicom 2000 systems. Installation is straightforward for integrators and facility managers looking to upgrade paging and surveillance workflows without complex rewiring. With a robust aluminum faceplate and proven Bogen build quality, the CA10A improves situational awareness, speeds operator response, and simplifies daily monitoring. Add the CA10A to your intercom or paging deployment to strengthen building communications and emergency procedures.
