D-Box + Star A3 Beta+ ASG 1XX + T-25 Instruction Manual

Code: DYN 62-2.05

Date: 20/12/2019

INTRODUCTION

DESCRIPTION

This system is made up of a D-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 D-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.

The assembly of this safety package in an installation exempts the installation itself from requiring the UCM certificate

but not from checking that the unit is in compliance with the standard's requirements. The installer must be held

responsible for fitting the system in the installation and checking its correct working order.
