This system is made up of:
SD-BOX PESSRAL UCM control electronic device
STAR overspeed governor + 24 VDC Anticreep device (the only compatible model)
ASG-1XX progressive safety gear + T-25 acting bar mechanism

This system operates as a complete system of protection against car unintended movements with the door open, also known as UCM.

This unit complies with the EN 81-20/50:2014 and EN 81-1/2:1998 + A3:2009 standards, by using the UCM control electronic device SD-DOX, the governor as a UCM detection component and the safety gears as braking components. The system stops the car when a UCM occurs at a distance lower than 1 metre in accordance with the standard.

This protection system is certified as detection and braking device in the scope of the system against car uncontrolled movements with door open. Moreover, each component making up the system is also individually certified as overspeed governor and progressive safety gear in descent and braking device against overspeed in ascent, apart from having the corresponding certificate as components of detection and braking devices in the scope of the system against UCM.
