Initiating devices can produce which type of signals, depending on the device and wiring?

• A. Alarm
• B. Supervisory
• C. Trouble
• D. None

Answer: (A)

Initiating devices are meant to kick off the fire alarm sequence by sending a signal to the fire alarm control panel. When one of these devices is activated, the panel interprets it as an alarm condition and begins to notify occupants and activate notification appliances. The wiring and device type determine what the panel sees, but the primary outcome of an initiating device activation is an alarm signal. Supervisory and trouble states are related to circuit or device faults or to specific supervisory devices, not the normal action of an initiating device, so the best choice that captures the typical behavior is an alarm signal.
