3226 Trunk Port FXO Doorphone

Analog Trunk Port FXO Intercom & Doorphone for Visitor Entry - Integrated Door / Gate Control Relay

The 3226 Trunk Port FXO Doorphone is a telephone-integrated door and gate entry security for visitor and guest communication. The intercom integrates door opening control using the convenience of a telephone key pad for activation. The 3226 is fully rated for outdoor use in commercial or residential applications.

The 3226 integrates with a telephone system via an analog trunk (FXO) port. Alternatively the intercom can connect directly to an analog telephone, two line preferred, where one line would be dedicated for intercom calls. The 3226 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 3226 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.

How it Works

  • Accepts a call when calling the doorphone directly
  • Pressing a pre-configured door open code (e.g. digit 6) from the telephone or device (e.g. mobile or wireless phone, soft client on a tablet or laptop) during the intercom call, will activate the 3226 door control relay to allow momentary unlock of the entrance for the visitor to gain access through the door or gate
