3226 Trunk Port FXO Doorphone

Analog Trunk Port Doorphone for Visitor Entry with Integrated Door / Gate Control Relay – 24V

The 3226 analog trunk port doorphone is an analog intercom for hands-free visitor communication at a secure entrance door or gate. This analog intercom / doorphone is outdoor rated.

  • FXO analog trunk port interface to a telephone system or directly to an analog telephone.
  • Digital speech technology provides superior voice quality.
  • NEMA 3R outdoor rated.
  • Seamless relay activation via telephone keypad during the intercom call for secure door or gate entry.
  • Two-piece solution including controller + intercom secures the access control relay.

Description

The 3226 analog trunk port doorphone is UL/CSA and FCC certified. This doorphone kit includes a controller, intercom station with stainless steel faceplate, surface mount bracket for wall mounting and 24V power supply. The intercom station can also be flush mounted into a double gang box (not included). Mounting gaskets are also included in the kit for installing the intercom in any outdoor environment. A brass faceplate is available for separate purchase.

How the Algo Analog Trunk Port Doorphone Works

Secure Door / Gate Access Control

A controller + intercom station are two components of the 3226 doorphone kit. The controller provides the telephone connection and the relay for door / gate access control. As the controller is generally located inside the premise, the 3226 is a secure solution in the event there is tampering of the public-facing intercom station. The access control relay is in no way exposed, and unauthorized entry to the building is prevented.

The 3226 access control relay can connect to any type of industry standard door strike, gate activation system or access / security control panel. A 30V 1A normally open or normally closed relay is available from the controller for this purpose. A door strike is not included with the 3226 doorphone kit.

VIDEO: How To Wire A Door Strike

Generally it is best the strike power be provided using the manufacturer’s power supply, however, the 3226 doorphone can provide 24V DC strike power (current limited to 300mA). The power supply is earth grounded to meet safety and regulatory requirements when extending the doorphone outside the perimeter of the building to a gate.

Auxiliary Low Voltage Inputs & Outputs

A number of low voltage programmable inputs and outputs available from the controller and intercom station. Common uses for the auxiliary relays include configuring an input to use an existing doorbell, for example, or a relay output to activate a loud ringer or strobe light for intercom call telephone ring alerting. A door sensor input is also available for configuration, including the option to activate an alarm if the door remains open for an extended period (e.g., tailgating, leaving the door ajar).

Legacy Analog Doorphone Retrofit

The 3226 is ideally suited as retrofit solution of an existing analog intercom. It is often the case that 24 gauge twisted pair wiring is used with legacy intercom systems. This wiring can be re-used to connect the 3226 controller to the Algo intercom station, thereby saving time and money in not having to re-wire. Twisted pair wiring can also be used to wire the relay for door / gate control. Note: The controller can only be wired to the Algo intercom station in the 3226 kit.
