Door Box, Algo 8028 SIP Doorphone
Use the Algo 8028 SIP Doorphone when a SIP Door Box is the right solution for
monitoring an entrance door.
Requires software version 3.43 or higher.
Description
The Algo 8028 SIP Doorphone is a SIP-based Door Box used to monitor an entrance door and is an alternative to
the traditional analog DSX Door Box (P/N 922450). The 8028 consists of a Door Station (Door Box), a Control
Unit, and a Power Supply. Just as with the analog DSX Door Box, a visitor at the door presses the doorphone
call button (like a door bell) to send chime tones or ringing to all extensions programmed to receive them. To
answer the chime or ringing, the called DSX extension user just lifts the handset. This lets the extension user talk
to the visitor at the doorphone. The doorphone is convenient to have at a delivery entrance, for example. Company
personnel don't have to monitor the delivery entrance; they just answer the doorphone instead.
The Algo 8028 SIP Doorphone installs as a VoIP extension programmed as a Door Box. It requires the
installation of a VoIP Daughter Board (VOIPDB). The VOIPDB (P/N 1091044) provides 8 maximum VoIP
gateway ports on DSX-40; 16 maximum on DSX-80/160. Available gateway ports may be restricted by licensing.
Note: The 8028 SIP Doorphone Installation and User Guide is an important companion document to the
doorphone. Be sure you have read this manual before attempting to install the doorphone on DSX.
8028 SIP Doorphone Relays
The 8028 Control Unit offers a flexible relay configuration for controlling an auxiliary device such as an electric
door strike. Any keyset extension that receives doorphone chimes or ringing can operate an 8028 Control Unit
relay. Relay features include:
•
Fail Locked (Fail Secure) electric door strike control. These types of strikes remain locked during a power
failure.
•
Fail Unlocked (Fail Safe)
electric door strike control. These strikes are unlocked during a power failure.
• Dry or wet relay contact applications .
In a dry application, relay contacts are unpowered and only provide contact closure to the connected
device.
