Signals from exterior space detection systems shall not be dispatched as an alarm unless:

• A. Visual verification is used
• B. Alarm verification is used
• C. A manual code entry is made
• D. A time delay is applied

Answer: (B)

The main idea here is that exterior space detectors are prone to false triggers, so signals from them aren’t treated as an alarm unless there’s a verification step. Alarm verification means confirming the initial trigger with a follow-up check—such as a second sensor corroborating the event, another trigger occurring within a short period, or a verifiable visual/remote check—before the system dispatches an alarm. This verification requirement is what makes the signal legitimate enough to be dispatched. Simple visual checks on their own aren’t automatic dispatch mechanisms, a manual code entry is something the user performs to acknowledge or disable alarms, and a time delay can slow responses but doesn’t by itself verify that an actual incident is happening.
