sliding door system includes
a quiet belt drive automatic door operator, a heavy duty aluminum
header/track, and insulated sectional metal door panels. The door's
rapid opening speed provides a full opening width in seconds. Vehicle
and pedestrian traffic do not need to wait for height clearance, as
with roll-up type doors. Pedestrian traffic is provided with a 48"
partial opening, while the door opens completely for vehicle traffic.
The door's fast opening speed greatly reduces the chance of door panel
damage, due to impacts.
The door can be actuated by wall switches, motion detectors, ceiling
mounted pull chains, presence detectors or traffic loop detectors.
Dual inputs are provided for a combination of switches; one set of
actuation contacts for pedestrians and one set for vehicle traffic.
Pedestrian actuation usually has automatic time delayed closing, but
vehicle traffic can be set-up as actuate to open/actuate to close. |
