ISSP

ComPoint can work with your multiroom audio system or function as a stand-alone intercom. The optional ISSP in-wall speaker makes this possible by working with any keypad to provide the ComPoint system's audio. You can use it for all zones or just the zones that aren't included in your multiroom system, like a hallway or basement.

ISDR1
The optional ISDR1 Door Strike Release Module provides a connection between your ComPoint system and a third-party electric door strike release (not available from Russound). This allows you to unlock the door from your ComPoint keypad.
