Anti-nuisance control (Event Handler)

This article describes how a master station can disable substations from making calls and audio program selection for a periode of time.

In the programming example below the master station dials 9535 + substation directory number to disable calls from that substation for 15 minutes. The feature code 9535 and the substation numbers can be assigned to DAK keys for easy operation. If the master station is a CRM IV or CRM V station with DAK48 panel, the "disabled" status will be indicated with a red LED in the assosiated button on the DAK panel.

Solution

Directory number 9535 is by default a two-step event trigger, feature 95/0. When 9535 + Substation is dialled, an event type 25 is triggered and the action string $SSC L%2.dir U2 moves the substation to COS 2. COS 2 is by default empty, which will prevent calls to be initiated. The command $DISCON_ST L%1.dir U2 will disconnect the master station with a success tone after having entered the substation number. The $PROG L%2.dir LV command will switch off audio program on the substation. A 15 minute timer is started by the command $ST L%2.dir W9000 L9999. When the timer expires it will trigger event type 21, and the command $SSC L%1.dir U1 will move the station back to COS 1, and calls and program selection can again be made.
