The AlphaCom exchange is a very powerful tool for both complex audio switching, and as a system integration tool. In many cases the AlphaCom can control everything, call queuing,, CCTV, pagers, remote control outputs like door opening, technical alarm inputs etc.
In other cases the customer wants screen based system integration (e.g. a building management system) as a common user interface, and uses the AlphaCom as a subsystem.
Throughout this document the term “PC” is used when referencing to “the external computer system “.
AlphaCom functionality for security systems
When the customer decides to have an audio system, the AlphaComs potential should be used. This means that door stations should have call (help) buttons, the guard workplace should have a Control Room Master station with queue display and answer possibility etc. The intercom stations will be very natural to use, and will also serve as a backup should the high-tech screen system fail.
The typical built-in AlphaCom features are:
- Call queuing.
A substation push button will dial a Call Request dir.no, which puts the station into a Control Room station’s call queue (sorted on priority and arrival time). The substation gets an (optional) voice message, then ringing and LED flashing while waiting.
Note that Call Requests will arrive into the Control Room station’s queue independent of the use of the
station - queuing will not be blocked e.g. by an on-going conversation.
- Conversation set-up.
The Control Room master typically establishes out-going connections, either due to a previous Call Request (dial 70+8 to answer first-in-queue), or on own initiative (keypad dialling or DAK key-press). An successful out-going connection will remove a possible Call Request from the called station.
- Sometimes substations are set to fixed PRIVATE, so that incoming calls will not connect unless accepted by the person in the room. The Control Room station must then be set to high call priority, in which case it connects directly when answering Call Requests.
- Speech direction control.
The AlphaCom operates normally in voice-switched duplex. Security systems often handle noisy areas, and the guard will often revert to simplex using the M-key while speaking.
- Remote Control.
During connection, the guard can press digit 6 on his station to cause a Remote Control Output related to the other station to pulse for 5 sec., typically opening a door. (Actually any action is possible. e.g. sending a data command to PLC which controls digital I/O etc.)
