Which device provides visible indication of the location of an initiated device to observers?

• A. A digital readout
• B. A separate audible alert
• C. Indicator lamp
• D. A color-coded tag

Answer: (C)

When a device is initiated, people nearby need a clear, immediate visual cue showing exactly where that activation happened. An indicator lamp serves this purpose by lighting up at the location (on the device itself or on a nearby local indicator) so observers can quickly identify which device was activated. This supports fast response by directing attention to the exact point of initiation. A digital readout on the panel can convey zone or system information, but it isn’t as immediate or local as a lamp right at the device. An audible alert tells that an alarm occurred but doesn’t provide a visible cue to the specific location. A color-coded tag is typically used for maintenance or status labeling, not for real-time indication of an active initiation.
