Door Release Trigger for IST I2000

The IST Door Release Unit is an interface that allows the "door" pushbutton of an indoor IST I2000 Room Station or Master Station to trigger the IST Door Release Mechanism (electric door strike, sold separately). This enables remote door unlocking from an indoor intercom station. The Door Release Unit mounts into a single-gang box near the door, and wires into the mechanism and the station via standard 16 gauge 2 conductor cable.
