IST Door Release Unit

The IntraSonic I1000DRM Door Release Mechanism is one component of the IntraSonic I1000 Intercom and Music Distribution system and IntraSonic Retro system. For the I1000 system, you must also purchase the IntraSonic door release unit (I1000DR) to allow an indoor station to push a button which unlocks the door for a person to enter. For the Retro system, the mechanism is activated by a 12V AC/DC Transformer. Obviously this is an optional product for IntraSonic intercom systems depending on your needs.

The door release unit, I2000DR, should be located close to each door or gate to be controlled. The unit can be mounted in a closet or somewhere out of sight close to each door or gate. Mounting is accomplished with a deep single gang box. Run standard 16 gauge 2 conductor cable from a 12 volt AC or DC source to the door release unit. Run another 16 gauge 2 conductor cable from the door release unit to the door speaker. Be sure to leave a service loop of approximately 10 inches on both ends.
