INTRODUCTION
DESCRIPTION
This system is made up of a SD-BOX signal control box, STAR overspeed governor, T-25 steering mechanism and
ASG-1XX progressive safety gear, everything manufactured by Dynatech. This system operates as a complete
system of protection against car uncontrolled movements with the door open, also known as UCM.
This unit complies with the EN 81-20:2014 and EN 81-50:2014 standard by using the SD-BOX as a signal
management system, the governor as a UCM detection component and the safety gears as braking components.
The entire system stops the car when a UCM occurs at a distance lower than 1 metre in accordance with the standard
requirements.
This protection system is certified as detection and braking device in the scope of protection against car uncontrolled
movements with door open. Furthermore, each component making up the system has also been individually certified
for this purpose; obviously, without negatively affecting its certification as overspeed governor and progressive safety
gears when descending and braking component against overspeed when ascending.
UCM certification also includes the combinations between the different versions of these component models.
