Algo 3226 Analog Trunk Port Doorphone for Visitor Entry with Integrated Door / Gate Control Relay – 24V
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 is full duplex capable, featuring echo cancellers and adaptive noise reduction 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 24 V 0.3 A power source for low power 24 V 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.
The 3226 kit includes the following: Door Station with a stainless steel face plate, Controller with 24V power supply, and a bezel for surface mounting. Please note that the Door Station can flush mount into a standard dual gang box. Mounting gaskets are included in the kit for installing the intercom in any outdoor environment.
