Siemens FDAI92 Alarm Indicator (surface-mounted)

FDAI92 alarm indicator is a surface-mounted warning lamp connected in parallel to detectors installed in non-visible locations. In areas such as suspended ceilings, raised floor plenums, ducts, and locked rooms where the detector cannot be directly viewed, it marks the alarm source from outside. The maintenance and response team reads from the corridor which hidden volume generated the alarm and proceeds to the correct location without removing ceiling panels.
