Mechanical Coordinator ABLOY® FD451

Mechanical Coordinator is designed for closing of leaves of two-leaf doors in proper sequence.

Field of application

Two-leaf doors by width of 1250 - 2500 mm.

Features

  • The width of the passive door leaf is at least 400 mm;
  • Can be used with door magnets ABLOY® 7438 and ABLOY® 7439;
  • Used with two closers of DC250 type or with two DC240;
  • Colour spectrum corresponds to the colour spectrum of covers for closers.

Normally in the daytime door leaves are closed and the active leaf is used for access. If it is required to keep both leaves open, at first it is necessary to open the active leaf (1) and then it is possible to open the passive leaf (2).

Coordinator keeps the active leaf at the necessary angle while the passive leaf is open. The passive leaf remains open if someone holds it or the door magnet is used.

When the passive leaf is closed (3), the active leaf starts to close (4).

Field of application

Two-leaf doors by width of 1250 - 2500 mm.

Features

  • Electromechanical device for keeping two-leaf door in open position;
  • The width of passive door leaf is at least 400 mm;
  • Open position of door is 80° - 130°;
  • Used with two closers of DC250 type or with two DC240;
  • Colour spectrum corresponds to the colour spectrum of covers for closers.
  • Installation only from the hand of door.

Two electromechanical devices for keeping door in open position FD452.

The devices for keeping door in open position keep a door open on the chosen angle (1). When power supply is off, for example, when sensors respond to smoke, the door closes in such a way: first the passive leaf (2) and when it is completely closed the active leaf (3) starts to open.

  • Open position of door is 80° - 130°;
  • Used with two closers of DC250 type or with two DC240;
  • Colour spectrum corresponds to the colour spectrum of covers for closers.
  • Installation only from the hand of door.

Pic. 1:

The device for keeping both leaves of door in open position.

Normally in the daytime both door leaves are open. The device keeps the active leaf open within the angle adjusted during installation. The active leaf is kept by coordinator. The angle of open position of the active leaf is adjusted to 150°.

When power supply is off (for example, when sensor responds to smoke) the passive leaf (1) is closed first and when it is completely closed the active leaf (2) starts closing.


Pic. 2:

The device for keeping the active door leaf in open position.

Normally the passive leaf is closed (1) and remains open if someone keeps it open.

When power supply is off (for example, sensor responds to smoke) the passive leaf (2) is closing.
