6.2  Emergency calls  
These calls are designed to send alarm signals easily in emergency situations. Typically, emergency 
situations involve injuries or material damage and have highest priority among all other alarm events and 
calls. 
Notification calls are made by pressing the following keys: 
 
The handset is communicating with the alarm server. The message that appears on the handset display will 
depend on your system configuration. 
The normal call processing message is displayed on the screen and, depending on the configuration, the 
user may receive an acknowledgement or in conference message. 
The notification calls are priority calls and can be performed in any handset status. Handset statuses are: 
idle, conversation, dialling, calling, configuration, put in charger, removed from charger. Any active call will 
be terminated as soon as a notification call is initiated. Notification calls will also interrupt any calls such as 
live, key event or status calls. 
During the notification process, all user actions are ignored until communication is established with the 
alarm server. Then either the user or the alarm server can terminate the call and the handset will return to 
idle state and will be available to process any subsequent user calls. 
6.3  Key event calls  
This feature allows you to send an information message to the notification server by pressing particular 
keys on the numeric pad. This Key event call can only be performed when the handset is in idle state. A 
typical application of this feature could be to press a specific key when a room is ready in the case of a 
hotel application. Each long press on a different key will send a different message to the server.  
•  1, 2, 3, 4, 5, 6, 7, 8, 9, 0 (long press). 
After activating the key event process, the user should wait until communication is established with the 
alarm server before pressing any key, to ensure it is functioning correctly. Then either the user or the alarm 
server can terminate the call and the handset will return to idle state and will be available to process any 
subsequent user calls. 
If configured in the key setting options, P1 and P2 keys can be used as key events. The use of these keys 
is equivalent to:
