View source for Unlock intercom station with password

{{AI}}
This article describes how a master station can be locked in idle, and unlocked by dialing a passcode. When the code is dialed, the station will be unlocked for a preset periode of time, then it will automatically be locked again.

The passcode is an [[Event Trigger (Event Type)|Event Trigger]] number. When dialed it will move the station to a [[Class of service|COS (Class of Service)]] in which all wanted features are enabled. Also a timer is started. When the timer expires, the station will be moved to a COS were all features are disabled, except the event trigger feature itself. 

* In AlphaPro - Directory & Features, '''Insert''' a new event trigger directory number with feature number 85, e.g. 9200.

* In AlphaPro - COS, modify COS 2 to include feature 85 only.

* Program two new events in the Event Handler.

In AlphaPro, select '''Exchange & System''' - > '''Events''', and '''Insert''' two events with the following properties:

'''Event 1''' - Unlock the station by moving the station to COS 1 when dialing passcode 9200. A 10,0 second timer is started.

{{Code2|
 [[SET_STATION_COS|$SSC L%1.dir U1]]
 [[SET_TIMER|$ST L%1.dir W100 L9200]]
}}

The parameter W100 = 10.0 seconds. Change if required.



'''Event 2''' - After the 10 sec timeout, lock the station by moving it to COS 2.

{{Code2|
 [[SET_STATION_COS|$SSC L%1.dir U2]]
}}

{{Note| By default all stations are in COS 1, and thereby "Unlocked". To prevent that a SendAll from AlphaPro will "unlock" all stations, it is recommended to "lock" all stations by moving them to COS 2 in the AlphaPro database.}}
