The Algo 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.
The Algo 3226 door control relay has the ability to 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.
