Door Opening using Dummy Number (Event Handler)
From Zenitel Wiki
Some gates are not equipped with door stations, but the operator should use the same Door opening procedure to open the door.
When the operator gets a signal that there is someone at the door he should dial a 'dummy' number, then press digit 6 to operate a relay output (i.e. a RCO). In the example below any station can dial 9545 + 6 to trigger RCO 4 for 2 seconds, and disconnect with success-tone. Use the two-step event trigger, feature 105.
In AlphaPro, Directory & Features, press "Insert" to create a directory number, feature 105, for each door. Directory number 9545 is included by default.
In AlphaPro, go to Exchange and System -> Events, press Insert and create the following event:
Subevent 6: Digit 6 When Change to ON: When the digit is pressed (not released) RCO 4 ON 20: Pulse RCO 4 for 2.0 seconds $DISCON_ST L%1.dir U2: Disconnect the station with successtone
