Personal Emergency Response System (PERS)
Formal
A mobile duress panic alarm component of a monitoring system, typically for the residential market.
Practical
Modern PERS devices go beyond their origins as a mere push button to include MEMS and various other sensors. Typical systems have a wireless pendant or transmitter that can be activated in an emergency. When the medical alarm is activated, the signal is transmitted to an alarm monitoring company's central station, other emergency agency or other programmed phone numbers.
