Door Operation for Types A, B, C, D, E, and F
In the operation of the door, the ETS-Lindgren cam-actuated latching mechanism
brings the door to a completely closed condition with the handle rotated to the full
stop position. Conversely, when the handle is rotated in the opposite direction to
the alternate position, the door knife edge is removed from the finger contacts,
allowing the door to fully open. In this position the door will swing freely with little
opposition.
When closing the door, normal door pressure should be applied until the
cam actuators are engaged in the cam blocks. At this point no further inward
pressure on the door is required. Rotate the door handle until the handle has
reached the full stop position. The cam action of the door latching mechanism
provides all the pressure required to separate and correctly contact the fingers.
On large double-leaf swing doors, the surface area of the contact fingers is larger
so the latching effort required is slightly greater. At no time should more than
hand pressure be required or applied to the latch mechanism.
Flush sill doors have a double or triple row of contact fingers fitted to the bottom
edge. These are exposed and should be checked periodically for damage.
