Call Request

Making Call Request

When you make a Call Request, you send 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 7 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
Global Call Request	627	100	Calling station display text
Clobal Alarm Call Request	628	140	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.

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 duplication of neither Call Requests, Technical Alarms nor other mail messages.

Call Request Verification

The initiator of the Call Request enters "Call Requester Mode" and gets a verification, an ASVP 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 the ASVP software module to be installed.
• 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.

Receiving Call Requests

Station Types

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

• Control Room Station - CRM
• IP Dual Display Station
• Dual Display Station
• IP Desktop Stations
• TouchLine Display Station
• Telephone/mobile phone connected via a SIP gateway.

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

Call Request Indication on CRM-IV Stations

The recipient of a Call Request gets the following indications on a CRMIV Control Room Station with a typical set-up for the LEDs:

• There is an attention tone in the receiving station for each new Call Request
• The red lamp starts to blink + reminder tone according to call priority
• The display shows the number of Call Request messages and the first two calls in the queue.

Messages: 2	The Number of queue entries
437 Door Call	First Call request in the queue
230 Cell Call	Second Call Request in the queue
ANSW NEXT M Canc	Text for Single-touch keys

Additional Information

• A Call Request to a MLH station or a CRM station will have different indications depending on the station features.
• A Call Request to a TouchLine display station: The display shows “Messages (2)”. You must press 70 to read the text first message in the queue.
• Display, buzzer and LED indications on the CRMIV station is programmable.

Call Request Indication on TouchLine Display Stations

• There is a notification tone in the receiving station for each new Call Request
• The red lamp starts to blink + reminder tone according to call priority
• The display shows the number of Call Request messages and the answer code.

Messages: 2	The number of queue entries
70 Read message

Identification of Call Request

For each Call Request directory number, you have the choice of showing either the initiator’s name, or the text of the Call Request itself on the recipient’s display. You can have specific Call Request number for calls from elevators, one for calls from doors and one from cells. The text “Lift Alarm”, “Door Call” or “Cell Call”, can then appear on the recipient’s display, instead of the name of the initiating station.

This option is programmable for each Call Request.

Priority Level of Call Requests and Alert at Receiving Station

The Call Request is treated as a mail message at the receiving station. Thus the priority levels for mail messages also applies to the Call Request messages.

Feature Reminder:	A reminder tone (bleep) in the station every minute and blinking LED every second.
Urgent Feature Reminder:	Attention tone (dut-dut-dut) repeated at intervals.
Notification:	Attention tone (dut-dut-dut) and a short display indication when the mail message is received.
Additional Queue Indication:	Output to an external lamp or buzzer. Indication on LEDs and buzzer on a Control Room Station.

Priority level	Feature Reminder	Urgent Feature Reminder	Notification	Add. Queue Indication	Built in for
100 101	x		x	x	623 Normal Call Request 625 Normal Call Request
140 141		x	x	x	622 Alarm Call Request 624 Alarm Call Request

Call Request notification when Station type is set to "CRM"

The original control room stations CRM III and CRM IV stations had an built in buzzer used for call request notification. Because of this the notification is not done through the loudspeaker when the station type in AlphaPro is set to "CRM".

With the introduction of Dual Display station and IP Flush master with 4 line display, the "CRM" station type is also used for these stations to get CRM functionality, but then no buzzer is available.

A station flag is introduced to allow normal mail notification also even when station type "CRM" is selected.

This flag can be set by this command:

$SNV Q%op(%gnv(5,8,%1.phy,17),|,8192) W5 W8 W%1.phy W17

Where %1.phy must be replaced by the actual physical number of the Control Room station. Event 27/65 - ON can be used to set this flag. Example: Set "Call Request notification" flag for physical number 49:

This flag was introduced in AMC software 10.56.

From AMC version 11.5.3.4 this event is no longer needed as the flag is automatically enabled for IP stations.

Additional Queue Indication Output

If you use a TouchLine Display Station you may need to have an additional queue indication to warn you when you have received a Call Request message at your station. If for example your station is in a noisy room, a flashing red lamp or a sound signal will be activated to notify you of a Call Request message.

• The Additional Queue Indication is activated by an RCO (Remote Control Output) when you receive a message with a priority level above a defined level.

By default this threshold is 100. It is programmable and common to all the stations in the system.

• The Additional Queue Indication feature must be programmed.
• If several high-priority messages are queued at your station, you may need to turn off the Additional Queue Indication temporarily, to avoid being disturbed by it when you handle the calls.
• To turn off the Queue Indication temporarily: Dial 7882. You switch the feature on by dialing 7882 again.

Additional Information

• If you have temporarily turned off the feature: when you have answered all the high-priority messages for your station, the Additional Queue Indication is automatically switched on again on receipt of a new message with high-priority level.
• On CRMIII/IV stations, there is output to an external buzzer.

Answering Call Requests
