The R700H protect handsets can be used as personal alarm devices with voice communication capability (PNG-S) in Alarm Mode and PNG Mode. Various settings are performed on the handset for this purpose, which enable automatic or manual alerting. An alarm and emergency call function is already available in Basic Mode.

The PNG-S monitors the person and reports an alarm when alarm conditions are detected. The following types of alarms and signals are possible:

• Manual Alarm:
  The user can trigger an alarm by pressing the alarm key.
  
  
• Man Down Alarm:
  The integrated movement sensors identify deviations of approx. 70° from the vertical position of the handset.
  
  
• No Motion Alarm:
  The integrated movement sensors detect immobility of the handset.
  
  
• Escape Alarm:
  The integrated movement sensors detect sudden, violent movements of the handset.
  
  
• Time Alarm:
  The operator's ability to respond can be controlled through regular operation of the handset. The user is prompted to input something at set times.
  
  
• Technical Warning Signal:
  The handset detects local technical faults or keep-alive requests. These are signaled to the user. Example: The handset is out of range or the battery charge is too low. The user can subsequently initiate measures in order to resolve the fault.
  
  
• A Pre-alarm informs the monitored persons of an impending alarm. The alarm can still be reset during the pre-alarm time in order to avoid false alarms.

The response time, pre-alarm time, possibly sensitivity level, alarm signal and alarm destination can be configured for each alarm type.
