Magnetic Switch Installation
To comply with UL Standards, a magnetic
•
switch must be deployed across all access
panels and doors that can expose an operator
to more than of 1.7 μW/cm2 UV intensity.
When possible, it is recommended to mount the
•
magnetic switch across two door panels.
Switch wires are not polarity-sensitive.
•
Max mounting gap: 5/8".
•
Remove interlock protective covers for access
•
to screw mounting holes. Replace protective
covers after mounting.
If installing the device in ducting with no
•
operator access, the magnetic switch can be
bypassed by wire-nutting the two signal wires
together.
