A verified alarm system is:

• A. Permits authorized personnel to identify themselves, preventing emergency response agencies from being requested to respond to non emergencies and confirm or deny the validity of alarm signals received at central.
• B. A system that notifies authorities immediately without verification.
• C. A home alarm that cannot be disarmed.
• D. A system that never requires verification.

Answer: (A)

A verified alarm system requires confirmation of the alarm event before authorities are dispatched. The monitoring center verifies the situation, often by contacting the location or using a secondary verification method, and only then requests a response from emergency services. This approach helps prevent wasted deployments due to false alarms.

The best answer describes this process: authorized personnel identify themselves at the central and confirm or deny the alarm’s validity before involving responders. That’s the essence of verification—ensuring the signal is real before dispatch.

Unverified systems dispatch authorities immediately, which can lead to more false alarms. A non-disarmable system or one that never requires verification does not align with the concept of verification before response.
