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.

An acknowledge code must be dialed from the stations in the special group to tell the CRM that the member has acknowledged the emergency call. When the code is dialed 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 dialed on the CRM station will turn off all LED indications on the CRM, and remove the display information from all member stations.

Configuration example

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

Configuration example

• 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.

Programming

Emergency Broadcast Activation

In the Exchange & System -> Events insert a new event:

Action commands:

IND %1.phy 0 0 0 OFF
IND %1.phy %1.DAK(I101) 1 2 ON
IND %1.phy %1.DAK(I104) 1 2 ON
IND %1.phy %1.DAK(I105) 1 2 ON
IND %1.phy %1.DAK(I106) 1 2 ON
IND %1.phy %1.DAK(I201) 1 2 ON
IND %1.phy %1.DAK(I202) 1 2 ON
IND %1.phy %1.DAK(I250) 1 2 ON
IND %1.phy %1.DAK(I401) 1 2 ON
IND %1.phy %1.DAK(I402) 1 2 ON
IND %1.phy %1.DAK(I450) 1 2 ON
@U1 $SM %1.ref NG20 U119 NM17 GV U0 'Emergency' U0
@U2 $SM %1.ref NG20 U119 NM17 GV U0 'Emergency' U0
@U3 $SM %1.ref NG20 U119 NM17 GV U0 'Emergency' U0

When the CRM dials the global group 9020, the first IND command will switch off all LED's in the CRM. The next IND commands will switch ON the red LED in the required DAK keys, and the SM command will send a mail message to stations in group 20 in each node 1, 2 and 3. The mail has priority 119, and the text 'Emergency' will be displayed. For the member stations it is recommended to enable the flag "Show Mail in Idle" found in the tab 'Station Type' in the Users & Stations window, as this will cause the mail text to be visible without having to dial the 70-code.

This event should be programmed only in the node where the CRM station is located.

Acknowledge Code

In each exchange select the Directory & Features window, and create an Acknowledge Code, say 9590, with feature number 85/0.

Create a new event which is triggered when the Acknowledge Code is dialed from any station. This event must be created in all exchanges:

Action commands:

@U1 $ER U15 U7 U1 U1 L500 U3 L%1.dir

When a station dials the acknowledge code, an ER (Event Report) command is sent to node 1 (must be sent to the node where the CRM is located). In node 1 the command will trigger an event of type 15, subevent 7, When Change To: ON, Owner: 500, Related To: The dialing station.

Acknowledge Event

In the node where the CRM is located, create a new event which is triggered by the ER (Event Report) command generated when the acknowledge code is dialled from any member station.

Action commands:

IND %1.phy %1.dak(I%2.dir) 2 1 ON
IND %1.phy %1.dak(I%2.dir) 1 2 OFF
$CANM %1.ref %2.ref NM255 U255

The IND command will turn the green LED on and the red LED off in the associated DAK key of the CRM station. The CANM command will delete the mail in the display of the acknowledging station.

Clear Code

In the exchange where the CRM is located, select the Directory & Features window, and create a Clear Code, say 9591, with feature number 85/0.

In the Exchange & System -> Events create a new event which is triggered when the Clear Code is dialed from the CRM station. This event is needed in the CRM exchange only:

Action commands:

IND %1.phy 0 0 0 OFF
@U1 $CANM %1.ref NG20 NM255 U255
@U2 $CANM %1.ref NG20 NM255 U255
@U3 $CANM %1.ref NG20 NM255 U255

When the Clear Code is dialed the IND command will turn off all LEDs in the CRM, and delete the display message from all stations in local group 20 in each of the nodes 1, 2 and 3.
