Mechanical timer

Adjustable hold-open time for sliding door closers – completey without power

Characteristics

  • Used on sliding doors that should remain open for a while before closing again, e.g. to allow a bed to be pushed through in hospitals
  • Strictly mechanical, without electricity
  • Based on the same hydraulic operating principle of door dampers, but with the opposite effect: a valve in the cylinder limits the flow rate of the oil. This determines the time after which the roller lever is completely folded down again and thus no longer held back by the hook. The door can close again.
  • Installed with the door in open position
  • Adjustable delay time
  • Opening time dependent on the closing force of the closing device used

Installation

Installation notes

The mechanical timer is usually mounted by means of a mounting bracket laterally on the wall in the opening direction. The hook is fixed at the back of the door leaf in a way that the roller lever of the mechanical timer enters the hook during opening and is completely folded up when the door is open.

Adjusting Range of Delay Time

The duration of the delay is adjustable. The adjusting range depends on the closing force of the spring rope pulley in the DICTAMAT 50, the counter weight or the like.

In the adjoining table you can see the duration as a function of the closing force of the closing device. The data applies at an operating temperature of approx. 22 °C.
