What type of signal is received when the system or a portion is placed in bypass or test mode?

• A. Trouble
• B. Alarm
• C. Supervisory
• D. System fault

Answer: (A)

When you place the system or a portion of it into bypass or test mode, the panel flags a trouble condition. This signaling category is used for abnormal or out-of-service states, and bypassing or testing a device intentionally removes it from normal monitoring, so the control panel indicates trouble to alert technicians that that portion needs service or is temporarily not in service. It’s not an alarm (no active fire detection is occurring), and it isn’t a supervisory signal (which would indicate a monitored device needing attention while still in service). The term “system fault” isn’t the standard label used for this maintenance state.
