Important Safety Notice
The 8028 SIP Doorphone is designed and tested to comply with EN 60950-1:2006 safety
requirements.
When the Doorphone Controller is connected to wiring that exits the building, there is
potential risk of lightning induced electrical surges or high voltages from fault conditions.
To reduce risk, outdoor wiring should be protected by Earth grounded conduit whenever
possible.
If outdoor wiring will be connected to the Doorphone Controller then the power supply provided
with the Doorphone Controller must first be connected to a properly Earthed mains supply.
Under no circumstances can the Doorphone Controller be disconnected from Earth ground while
connected to outdoor wiring.

Introduction
Ideal for secure business entrances, emergency intercom, and residential gates,
Algo’s 8028 SIP Doorphone provides
hands-free intercom capability,
entrance security with door unlock
control, rugged weatherproof design,
and superior audio performance.
Fully compatible with SIP industry
standards, the 8028 SIP Doorphone
will work with most hosted or
enterprise SIP-based servers supporting
third-party SIP endpoints.
The 8028 Doorphone includes a
Control Unit, Door Station, and Power
Supply. The Control Unit and Door
Station can be connected with a single twisted pair wire up to 1,000 feet (300
m) with the Door Station located outdoors and the Control Unit in a dry indoor
location.
Features
• Suitable for commercial or residential applications
• Door Station connected by a single twisted wire pair
• Full duplex capable hands-free voice communication at the Door Station
• Door control relay contacts and available 24 Vdc 0.3 A strike power
• Auxiliary dry contact inputs and outputs from Doorphone Controller and
Door Station
• Programmable via Web Interface
• International 110/220 V, 50/60 Hz switching power supply
• Regulatory: CSA/UL, FCC Class B, CE, EN60950-1 2006 CB Scheme

Quick Install & Test
SIP Server
The 8028 SIP Doorphone requires minimal configuration for a typical
installation. Programming is only required to enter the SIP account details, and
for more advanced applications.
1. Connect the power supply to the
Power Jack of the Doorphone
Controller and plug into an
available AC outlet.
2. Flush or surface-mount the Digital
Door Station at desired location and
connect a twisted telephone wire
pair between the “CTRL” terminals
of the Door Station and the center
pair (red and green) of the supplied
Telephone Wiring Jack. Polarity is
not important.
3. Using the short six conductor modular
cable, connect the Telephone Wiring
Jack to the Door Station Jack of the
Doorphone Controller.
4. Using an Ethernet cable, connect the Ethernet Jack of the Doorphone
Controller to your LAN.
5. Press the Call Button on the Door Station. A recorded voice will speak the
IP Address of the device. Enter this address in a PC web browser in order
to open the Web Interface. Note: The spoken IP address feature will be
automatically disabled after a SIP Server is configured in Step 6 (below).
6. Use the Web Interface to enter the SIP Proxy Server address as well as
the user account and password that the 8028 SIP Doorphone will use to
register. Also enter the target extension that the Doorphone will call.
7. Press the Call Button on the Door Station, then answer to communicate with
the Door Station. Press the digit 6 on the phone keypad to activate the door
control relay for three seconds (if applicable).

Applications
Typical Applications for Auxiliary Inputs and Outputs
The 8028 architecture and digital link between the Door Station and Controller
provides flexible options using the auxiliary inputs and outputs. These are some
typical applications:
Cancel Ring When Door Opened
In a residential or warehouse installation it is not uncommon for the door to
be answered in person before the phone is answered. Either Door Station or
Control Unit inputs can be configured to cancel ring if the door is opened
before a call is answered. This requires a normally closed or normally open
contact to detect door open.
Trigger Door Bell from Door Station
When the Door Station call button is pressed, either (or both) the Door Station
or Control Unit dry contact output can be configured to activate a door bell or
auxiliary alerting system in addition to phone ring.
Trigger Door Station from External Button/Event
Either the Control Unit or Door Station can accept a dry contact closure to
activate the Doorphone as if the call button had been pressed. This could be an
external doorbell button, PIR detector, or some other system.
Cancel Door Open Relay once Door Opened
The door opening control can be set for activation (using the `Open Code’) up
to 30 seconds (set by the `Relay Time’ setting) to allow sufficient time for entry.
For security, the 8028 Doorphone can be configured to cancel Door Opening
once the door is opened to prevent “tailgating” by unauthorized personnel.
Unlock Door Indefinitely until Canceled
The door opening control can be set to unlock indefinitely (using the `Latch
Open Code’) until canceled (using the `Release Code’) that locks it again. This
allows an entrance to be used repeatedly for a period of time without requiring
multiple activations of the door control relay.

- 7 -
Anti-Door Tamper
A feature of the 8028 Doorphone is to ring the telephone(s) with a warning alert
in the event a door is ajar due to tampering (such as a door blocked open after
being legitimately released for a visitor).
In-Use and Ring
Either the Control Unit or Door Station can be configured to provide a dry
contact output during ring or in-use for channel selection (typically) of third
party video monitoring systems.

- 8 -
Door or Gate Control Basics
Control contacts are provided from the Doorphone Controller and are typically
used for door strike activation or gate control. For security, the door control
relay is located in the Controller to avoid entry by tampering. The Door Station
dry contact output (OUT) may be configured for ‘low security’ gate control
requiring a low current dry contact.
Door Release
Door release typically involves energizing or de-energizing a door strike which
pivots to allow a locked door to open without retraction of the latch bolt. There
are two different types of door strikes:
• “Fail Locked” (or “Fail Secure”)
• “Fail Unlocked” (or “Fail Safe”)
24V 0.3A
Door
Strike
“Fail Locked”
24 Vdc 0.2 A Typical
24V 0.3A
“Fail Unlocked”
24 Vdc 0.2 A Typical
Fail Locked / Fail Secure Electric Strike
These require power to release and
remain locked during power failure. The
door may still normally be opened from
the outside with a key, or from inside
without a key. The door control relay is
used to apply power to release the door.
Fail Unlocked / Fail Safe Electric Strike
These (as well as magnetic locks), require
power to lock and become unlocked
during power failure. The door control
relay is used to maintain power to the
door lock (NC and C contacts) which is
interrupted to release the door. Magnetic
locks may require override systems to
allow safety exit in the event of fire.

- 9 -
Power Supply
The Doorphone Controller provides an auxiliary 24 V 0.3 A power supply
which is suitable for common types of door strikes. If more current or a different
voltage is required, then the customer must provide a matching power supply
for the electric strike or magnetic lock. Maximum switching capability of the
door control contacts is 1 A 30 V.
The Door Control relay may also be configured for alternate functionality
including In-Use, Ring, and Call Button Press.

firmware may be modified through the web interface and Algo routinely
accepts requests for custom firmware for unique applications.
