Which device is responsible for processing signals from detection devices?

• A. Fire alarm control panel
• B. Remote annunciator
• C. Control relay
• D. Main control valve

Answer: (A)

The fire alarm control panel is the device that processes signals from detection devices. Detectors send status information over initiating circuits to the panel, which monitors for alarms, supervises circuit integrity, and trouble conditions. When an alarm is detected, the panel coordinates responses such as sounding audible/visible alarms, indicating the condition on indicators, and optionally signaling remote monitors or building systems. A remote annunciator simply displays the panel’s status at a distant location and may allow local control or acknowledgment, but it does not process detection signals itself. A control relay is used to switch other equipment on or off under the panel’s command; it acts on the panel’s outputs rather than processing the detectors’ inputs. The main control valve relates to a suppression system’s water supply and is not involved in processing signals from detection devices.
