Personal Emergency Response Systems are typically connected to what type of line?

• A. Ethernet line
• B. Telephone line
• C. Fiber optic line
• D. Microwave link

Answer: (B)

PERS alerts are built to rapidly reach a monitoring center by using the home’s existing communications path. The steady, universal way to do that is through the standard telephone line, so when the alert button is pressed, the base unit dials out just like a regular phone call and often allows two-way spoken communication during the response. This makes the system simple to install and reliable, since most homes already have a landline ready for dialing out to a monitoring service.

Ethernet, fiber optic, and microwave links are geared toward data transmission and higher-speed networks, not the straightforward dial-out alert path these systems traditionally rely on. While newer setups can incorporate cellular or IP-based connections, the classic, test-favored configuration uses the telephone line.
