• Install the sensor in a shaded area, out of direct sunlight.
• Locate no higher than 2/3 up the side of the building, or between the 2nd and 3rd floor if the building is more than
three stories tall.
• Do not locate under an overhang, near wall corners, near drafts from stacks, air-moving devices, windows, doors, or
balconies.
• Shielded cable length run is not to exceed 300 feet.
• Install with properly-sized conduit that contains no other wiring.
