The IS-SS-CI is a stainless steel flush mount audio door station, equipped with a CCTV camera input for integration of a separate camera for viewing the area where the unit is located. The call button will trigger two selectable relay outputs for activation of external systems or devices. The associated camera will come on when a call is placed from the unit, or when called by the master station. A call status indicator will light when the station is in communication with a master station. The unit is made of stainless steel and includes tamper resistant screws. The IS-SS-CI is compatible with the IS series communication system. Wiring is CAT-5e or CAT-6 to the designated exchange unit (IS-CCU, IS-SCU).
