Esser 32L×254D-C

Esser / Honeywell Esser 32L×254D-C is a shipboard unit in the Fire Detection Systems group, classified in the source as Addressable Fire Detection Panel. It is normally installed in fire-control stations, bridge or safety centers, with detectors and loops distributed through accommodation, machinery and service spaces. Its primary duty is to detect fire signatures, identify the affected zone and initiate alarms or related safety functions. In service it interfaces with smoke/heat/flame detectors, loops, manual call points, sounders, remote panels, shutdowns, dampers and vessel alarm systems. Compared with neighboring entries in the same product family, this record is the exact Esser / Honeywell Esser 32L×254D-C variant; the model designation should be retained unchanged when matching onboard documentation and spares. For exact limits, settings, test values and approved maintenance criteria, refer to the manufacturer documentation for the exact figure.
