These systems automatically shut down engines, generators, blowers, and other connected equipment when a Fireboy system discharges. Select the correct engine shutdown based on system voltage (12V, 24V, 32V) and the total number of circuits to be shutdown. In accordance with Fireboy-Xintex instructions, an Automatic Engine Shutdown system is required on all diesel engine applications with an installed pre-engineered fire suppression system, and highly recommended for all other applications. New ESC systems are wired internally, with no exposed connections, and boast three viewable LEDs to keep you abreast of system status. Includes USCG-required helm station system operational light, integrated alarm/horn, charged/discharged lights, and an override switch for restart control of auto-shutdown.
