Which option best describes the RED alarm color?

• A. Tamper Alarm.
• B. Alarm point is secure.
• C. Activation of interior device such as motion or passive sensor.
• D. Power/communication failures.

Answer: (C)

The red alarm color signals an active alarm condition caused by an interior sensor being triggered. When a device like a motion detector or interior passive sensor detects movement or an intrusion, it generates an alarm that is shown in red to indicate urgency and require immediate verification and response.

Tamper alarms indicate device tampering and are typically shown with a different indicator, not the red alert for an active intrusion. An alarm point being secure means nothing is triggering at that point, so it wouldn’t be red. Power or communication failures point to system faults and are usually indicated by a different color or status. Thus, red best describes the activation of interior devices such as motion or passive sensors.
