Removing a non-portable RF transmitter from the system will trigger which signal?

• A. Local audible alarm
• B. Battery warning
• C. System-wide supervisory signal
• D. No signal

Answer: (C)

Supervisory signaling is used to monitor the presence and integrity of fixed, supervised devices in a burglar/residential alarm system. A non-portable RF transmitter is expected to continually communicate its status to the control panel. If the transmitter is removed, that ongoing supervision is broken, and the panel issues a supervisory fault. This fault is typically communicated system-wide to the monitoring station and to the panel, signaling a tamper or device removal scenario. It’s not an actual local alarm for an intrusion, and it isn’t a battery warning, and there is indeed a signal present, so the system-wide supervisory signal is the correct outcome.
