Roll Up Doors
For this type of door, mount the transmitter in a location high
enough off the ground to reduce the chance of physical damage,
and close enough to the door for the magnet to work. PTI
recommends mounting the transmitter on the facing of the door
frame on the side of the door opposite the hasp.
Some roll up doors are equipped with a foot plate at the bottom of
the door that has to roll past the transmitter as the door opens; the
foot plate must clear the transmitter. If the door is equipped with
a foot plate on each side, the transmitter can be mounted on the
header of the door.
Take care when selecting a location; over time, many roll up doors
move away from their tracks, and the door frame at the top of the
door. This movement can create a gap too large for the magnet
to work. Additionally, there must be very little movement when
the door is latched, from wind or other vibration. Such movement
generates an alarm.
The position of the magnet determines the mounting location for
the transmitter. The magnet must be mounted in the trough of the
door corrugation so that it will roll up without putting stress on the
door mechanism or the magnet.
Position the magnet with the smallest possible gap between the
magnet and the transmitter box. The transmitter box should be as
close to the magnet as possible. At no time should the magnet
be more than ½" from the transmitter box after installation.
U se the alignment marks on the transmitter box to position the box
and magnet.
Remember that roll up doors can move due to wind or other causes.
Wear on the track and flexure from opening and closing the doors
repeatedly will add to the door movement. Set the gap between
