Maretron ALM100-01 NMEA 2000 Alarm Module
Maretron ALM100-01 NMEA 2000 alarm module combines a 105 dB sounder, red warning LED, green status LED, and 32 patterns.
The Maretron ALM100-01 Alarm Module provides integrated audible and visual warning for an NMEA 2000 vessel monitoring network. It features a 105 dB piezoelectric sounder, a bright red alarm LED, a green power/status LED, and 32 selectable sound patterns, allowing different monitored conditions to trigger recognizable signals.
The module is powered from the NMEA 2000 network at 9–32V DC and is rated IP67 for installation inside or outside the vessel. It can mount to a standard single-gang electrical box or directly to a surface and is designed for use with compatible Maretron displays or N2KView monitoring software. The ALM100-01 version includes a black cover plate.
