PROTECTING WOOD DOOR THRESHOLDS<br />
WITH RECESSED CONTACTS<br />
For wood 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 />
Select a recessed-mount wide gap switch.<br />
Drill horizontal hole for magnet in outside edge of door. Coat magnet with RTV<br />
mounting compound. Insert magnet in hole. If using a wide gap switch with bare<br />
magnet, insert with red end of magnet toward outside of door (switch is polarity<br />
sensitive).<br />
Remove threshold.<br />
Attach switch on inside of threshold with RTV mounting compound. Position it so<br />
it will be directly beneath (and parallel to) magnet when threshold is replaced.<br />
Replace threshold.<br />
Test switch with ohmmeter while opening and closing door.<br />
Connect switch to alarm loop.<br />
