3228 Station Port FXS Doorphone

Analog Station Port FXS Doorphone & Intercom for Visitor Entry - Integrated Door / Gate Control Relay

The 3228 Station Port FXS Doorphone is a telephone-integrated door and gate entry security intercom for visitor and guest communication. The intercom integrates door opening control using the convenience of a telephone key pad for activation. The 3228 is fully rated for outdoor use in commercial or residential applications.

The 3228 integrates with a CO line or more commonly with a telephone system via an analog station (FXS) port or ATA. The 3228 intercom is full duplex capable, featuring an echo canceller for superior voice quality compared to most analog systems. Convenient single twisted pair wiring to the door station enables fast and easy installation for a new system or retrofit/upgrade of an existing intercom.

The 3228 door control relay can connect to any type of door release, gate activation system or access control panel. The intercom includes a 24V 0.3 A power source for low power 24V DC door strikes (customer provided). Additionally, there are low current programmable inputs and outputs at both control unit and intercom station for door sensing, door unlock switch, door unlock override, auxiliary call buttons, or telephone status such as ringing or in-use.
