Sensor Adjustment
Adjust the position of the sensor element, so the arrow
always points up by removing and replacing the
element to accommodate the possible placement
positions (Figure 12 on page 37).
Route the wiring from the sensor element so it does
not make contact with the tamper spring (Figure 13 on
page 37).

from its base or the unit is pulled away from the wall.
