The 3004 Intercom Station is a replacement part for legacy 3006/3008/3026 doorphones. It must only connect to an Algo legacy Controller. Please Note: The 3004 is not compatible as a replacement door station for 3226/3228/8028 doorphones.

Note: The legacy Controller for 3006/3008/3026 doorphones is no longer available as a replacement part. The Algo 3226 Trunk Port Doorphone kit replaces the 3006/3026, while the 3228 Station Port Doorphone kit replaces the 3008 doorphone.
