Emergency group call with acknowledge

Feature

A special group of stations receives emergency broadcast from a CRMIV or CRMV station. The members can be located in different nodes in AlphaNet. When the CRM station activates the emergency call, the corresponding LED's in the DAK module gives a red slow blinking. At the same time a display message is transmitted to the members.

There is an acknowledge code to dial from the stations in the special group to tell the CRM that the member has acknowledged the emergency call. When the code is dialled the LED indication will change to steady green, and the display message will be cleared from that station. For those stations who don't acknowledge the call, the display message will remain in the station to indicate that the emergency call has been active while they were away.

A "Clear" code dialled on the CRM station will turn off all LED indications on the CRM, and remove the display information from all member stations.

Configuration

Let us say that the members of the special group are:

• Node 1: Stations 101, 104, 105 and 106
• Node 2: Stations 201, 202 and 250
• Node 3: 401, 402 and 450

• The CRM directory number is 500. The station numbers above must be assigned to DAK keys on the CRM station.
• Include the stations in the local group 20 in each exchange, and include the local group 20 in global group 20. Assign a directory number to the global group 20, say 9020. The CRM station can now dial 9020 to do the emergency broadcast.

Event Handler programming

The CRM IV leds are configured from the Event Handler in AlphaPro. The leds are controlled by the IND command. Go to Users & Stations, select the CRM IV in the list box, and press Events. Insert an event as described below.

Emergency broadcast activation

When the CRM dials global group 9020, turn on red LED in the required DAK keys, and send mail to stations in group 20 in each node 1, 2 and 3. The mail has priority 119, and the text 'Emergency' will be displayed.
