The Digital Overspeed Switch (DOS), a product of Wildfire, continuously monitors the engine's speed through the use of a microcontroller which, once overspeed is detected, re-validates that the condition exists then immediately shuts down the pumpset.
Adjustment of a tension spring is no longer required. An "ON/OFF" switch is also no longer required. This also reduces the amount of wiring and spare parts necessary for each unit. Can be installed on any MARK-3® equipped with electronic ignition module.
