Videx 502N Audio Intercom Switcher | L2519

The Videx 502N is the entrance switching relay used on compatible traditional audio intercom systems with more than one door station. When a visitor calls, the unit switches the speech lines and associated services to the entrance that generated the call, allowing the resident to speak to the correct door and operate its lock release.

One switcher is used on a two-entrance system. For installations with three or more entrances, one unit is required for each entrance. The module is housed in an eight-module A-type DIN enclosure for rail or wall mounting.
