Description

The Battery Cut off Safety Switch (BCSS) main function is switching off the battery supply to the vehicle’s power distribution system under specific conditions. The purpose is to prevent electrical energy from the battery to potentially provide an ignition source for causing or re-igniting a fire. Vehicles equipped with Fire Suppression Systems can be connected to this device. Preventing a fire from being re-ignited through an electrical current.

The BCSS functions as an intelligent switch with 2 remote inputs that can be commanded to first stop the engine and then turn OFF the Battery Power once a Fire Suppression System (or any other critical safety system) has been activated.

These inputs are typically connected to a FSS and vehicle Park Brake. When FSS signals a fire condition, and the Park Brake signals vehicle safely parked, the BCSS will cut off the Engine Energize-To-Run (ETR) signal and after a programmable time delay, cut off the Battery Power.
