Mounting Location Guidelines
• 2.3 m (7’6”) mounting height
• Avoid direct or reflected sunlight
• Aim sensor away from windows or heating/
cooling devices
• Sensor must have a clear line-of-sight to
protected area
• Use a small screwdriver to unfasten the housing
latch. Gently pull apart the housings.
• Push outward on the PCB latch and lift the PCB
out of the housing.
• Slide the wire through the wire channel in the
back housing.
• Mount the back housing flat against a wall or in a
corner.
• Replace the PCB.
• Connect wires as shown using 0.3 - 1.0 mm
2
(18 to 22 gauge) wire size. Observe proper
polarity.
• Use Switch 3 to select the appropriate fluorescent
light filter (see Dip Switch Settings chart on the next
page).
• Apply power to the unit. Initialization is complete
when the LED stops flashing slowly.
• Adjust the microwave range to minimum setting
(25%) by turning the range adjustment counterclock-
wise using a small screwdriver.
