Personal Emergency Response systems are best described as

• A. A stationary alarm panel with no connectivity
• B. A wearable panic button only
• C. A monitoring service that does not use telephone lines
• D. An in-home transmitter or a two-way radio device connected to a telephone line that alerts a monitoring station and summons emergency assistance

Answer: (D)

Personal Emergency Response systems provide a quick way to summon help by activating a device that connects to a monitoring center. The essential feature is that the device communicates with a monitoring station so trained staff can respond and, if needed, dispatch emergency services. This connection is typically via a telephone line, though many modern systems also use cellular or wireless links. The description that fits best is an in-home transmitter or a two-way radio device connected to a telephone line that alerts a monitoring station and summons emergency assistance. A stationary panel with no connectivity wouldn’t reach a monitoring center, a wearable button alone doesn’t include the monitoring linkage, and a service that doesn’t use telephone lines would miss the critical dispatch capability.
