The fire door travels quickly until it reaches the lever. It is then gently decelerated by the lever mounted shock absorber and closes without shock or danger to personnel. The use of ACE shock absorbers allows higher operating speeds and weights as well as protecting the drive mechanism and housing from shock loads. The gentle deceleration of ACE shock absorbers makes the use of adjustable stop clamps possible and removes any chance of the clamp slipping. The kinetic energy is completely removed before the mechanical stop is reached thus making high index speeds possible. By means of a lever the effective stroke length can be increased and mounting space to the left reduced. 50% lower reaction force (Q) 50% lower deceleration (a) By driving 2 shock absorbers against one another ’nose-to-nose’, the effective stroke length can be doubled. 8.1 8.2 Safety travel (prevents trapping) 7.
