Call Request

Making Call Request

When you make a Call Request, you sent a mail message to a station that you want to speak with someone. A Call Request can be sent from any type of station.

Typical applications are calls from lifts, doors or prison cells to a supervisor using a Control Room Station. The Call-in point is then often a substation with one call key where the Call Request number + number for receiving station is programmed.

The AlphaCom autoload provides 5 different types of Call Request:

Feature name	Autoload number	Default priority level	Display Text in receiving station
External Call Request	621	Depends on type of station	Depends on type of station
Call Request 1	623	100	Calling station display text
Call Request 2	625	101	Call Request display text
Alarm Call Request 1	622	140	Calling station display text
Alarm Call Request 2	624	141	Call Request display text

The External Call Request is used for setting up Call Requests to MLH and CRM stations. You can have several external Call Request numbers in the system. The priority level and display information depends on the settings in the MLH/CRM stations.

Additional Information

• The Call Request message is handled as a mail message.
• Call keys on the substation are programmed using the AlphaPro programming tool.

Repeated Call Request

If the person at the call-in point presses the same Call Request key several times, it is only registered once at the receiving station. The system registers neither duplication of Call Requests, Technical Alarms nor other mail messages.

Software

• AMC 06.00 and later

Call Request Verification

The initiator of the Call Request gets a verification, an acknowledge message, which is the same regardless of the type of Call Request that is sent.

• At the call-in point you can hear a voice message (requires ASVP-board in the exchange).
• The lamp on the station blinks and there is a ringing sound until the Call Request is answered.

Additional Information

• The message to the caller is: “The call is registered, please wait”. The message is repeated in three languages ( English, German and French).
• With the Norwegian ASVP-board in the exchange the message is repeated in four languages (English, German, French and Norwegian).
• Your station is free to receive incoming calls while you are waiting to receive an answer.
• If you have received an ordinary call while waiting for answer to a Call Request, the lamp indication and ringing is removed even if your Call Request has not been answered.

Software

• AMC 07.20 for ringing sound until Call Request is answered.

Receiving Call Requests

Station Types

You can receive and answer Call Requests from several types of stations:

• CRM IV Control Room station
• CRMIII Control Room station
• CRM Control Room Station
• MLH Control Room Station
• TouchLine Display Station
• Telephone connected via the PNCI (Public Network Connection Interface).

Depending on the type of station you use, the Call Request indications and answering possibilities are different.

Additional Information

• A TouchLine Display Station can be used in CRMIV mode. The display then shows the upper two lines of the CRMIV display indication.
• An additional 2-line display (100mm x 30 mm) can be connected, thus making the display indication more visible on a TouchLine station. (Order no. 1009940120).
