Buried Floor Switch<br />
Sometimes it is necessary to bury a magnetic contact in the floor, due to<br />
construction, or to permit fork lifts and other vehicles to pass in and out. A Sentrol<br />
switch has been designed for this installation. It features stainless steel for<br />
corrosion resistance and a wide gap operation for loose-fitting overhead doors.<br />
Select position of switch that will minimize amount of concrete to be chipped out.<br />
Install magnet on door and lay switch on floor. Test to make sure switch operates<br />
with at least 1" (2.54 cm) gap. If not 1", adjust magnet position.<br />
Chip concrete out approximately 1/2" deep x 1/2" wide (1.27 cm x 1.27 cm) for<br />
switch and cable.<br />
Lay switch in hole and test. Test— make sure of at least 1/2" extra gap.<br />
Pull cable through protective conduit and connect to switch.<br />
Test proper operation of switch by closing and opening door.<br />
Cover switch and cable with concrete patch.<br />
