PROTECTING STEEL DOORS<br />
WITH THRESHOLD CONTACTS<br />
For steel doors with aluminum thresholds, it is sometimes convenient to mount<br />
the magnet in the bottom of the door and the switch in the hollow space beneath<br />
the threshold.<br />
Note: Because of the distance between the magnet and switch, a Sentrol wide gap<br />
switch should be used.<br />
Use a Sentrol steel door magnet combined with a Sentrol wide gap switch.<br />
Remove door from hinges. Drill 1" (2.54 cm) diameter hole in bottom of door<br />
about 2" (5 cm) from front edge of door. Glue with RTV or epoxy and snap-fit<br />
magnet into hole.<br />
Remove threshold.<br />
Attach switch on inside of threshold with RTV mounting compound. Position it so<br />
it will be directly beneath and perpendicular to magnet with end centered beneath<br />
it when threshold is replaced.<br />
Replace threshold and door.<br />
Test for correct operation with ohmmeter while opening and closing door.<br />
Connect switch to alarm loop.<br />
