IP Door phone with Secure Door / Gate Control Relay – Easy Retrofit Solution for Analog Systems – PoE
The 8028 SIP Doorphone (G2) is powered via PoE and is UL/CSA, FCC and CE certified. This doorphone kit includes a controller, intercom station with stainless steel face plate and a surface mount bracket for wall mounting. 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 face plate is available for separate purchase.
A controller + intercom station are two components of the 8028 IP doorphone. The controller provides the network connection and the relay for door / gate access control. As the controller is generally located inside the premise, the 8028 is a secure solution in the event there is tampering of the public-facing intercom station. The relay and network connection are in no way exposed, and unauthorized entry to the building or access to the network is prevented.
The 8028 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 8028 controller for this purpose. A door strike is not included with the 8028 IP doorphone.
Generally it is best the strike power be provided using the manufacturer’s power supply, however, the 8028 IP doorphone can provide 24V strike power when powering the doorphone with PoE + (IEEE 802.3at) or purchasing the Algo X24VG Power Supply. Powering the device via PoE (IEEE 802.3af) provides no strike power. Please see the 8028 product specifications for the available strike power amperage with either the PoE + or Algo power supply option. Note: When extending the 8028 outside the perimeter of a building the X24VG Power Supply is recommended for earth grounding to meet safety and regulatory requirements.
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).
The 8028 SIP Doorphone eliminates the need for an ATA or FXS port.
When migrating a legacy telephone system to VoIP, the 8028 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 8028 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 Algo 8028 controller cannot be wired to a legacy analog intercom station.
