Abstract: In the system, exits are provided with opening bars and locks. The system has a central post and control boxes. Each control box is associated with an exit and is connected to the central post. Activation of an opening bar initiates the sending of information to the central post by the associated control box. This triggers a first delay To. During this delay, the opening of the exit can be stopped for a further delay Tc. The opening is allowed at the end of the first delay or at the end of the second delay. A third delay Tp can be triggered during the second delay Tc to allow the opening of the exit under question during the third delay Tp and to relock the exit under question at the end of the third delay Tp, by cancelling the effect of the second delay Tc. The system can also operate in the anti-intrusion mode. In particular, it can be used in stores or public establishments of medium area.

Abstract: A typical door closer has a cylinder in which a piston reciprocates to compress a spring. An assistor for such a closer has a cylindrical shell fastened to one end of and continuing the cylinder. The shell has a barrier wall at one end adjacent the cylinder, a partition wall dividing the shell into a booser compartment and a main compartment, and a head wall at the other end. Air under regulated pressure is supplied to the main compartment, wherein the air presses a main plunger tube, extending through the partition wall, against a booster plunger having a rod extending through the barrier wall and abutting the piston. A port in the plunger tube receives air from the main compartment through the tube. In some plunger tube positions the port is blocked by the partition wall and in other plunger tube positions opens into the first compartment. A check valve when open allows air flow from the booster compartment to the main compartment.
