Theuseof ACE shock absorbers allows higher operating speeds andweights aswell as protecting thedrivemechanism and housing from shock loads. Thegentledecelerationof ACE shock absorbersmakes theuseof adjustable stop clamps possible and removes any chanceof the clamp slipping. The kinetic energy is completely removedbefore themechanical stop is reached thusmakinghigh index speeds possible. The firedoor travels quickly until it reaches the lever. It is thengently deceleratedby the levermounted shock absorber and closes without shock or danger topersonnel. Bymeans of a lever theeffective stroke length canbe increased andmounting space to the left reduced.
