Protecting Wood Door Thresholds with Recessed Contacts
APPLICATION
For wood doors with aluminum thresholds, it is sometimes convenient to mount the magnet in the bottom of the door and the switch in the hollow space beneath the threshold.
Note: Because of the distance between the magnet and switch, a Sentrol wide gap switch should be used.
INSTALLATION
Select a recessed-mount wide gap Interlogix switch.
Drill horizontal hole for magnet in outside edge of door. Coat magnet with RTV mounting compound. Insert magnet in hole. If using a wide gap switch with bare magnet, insert with red end of magnet toward outside of door (switch is polarity sensitive).
Remove threshold.
Attach switch on inside of threshold with RTV mounting compound. Position it so it will be directly beneath (and parallel to) magnet when threshold is replaced.
Replace threshold.
Test switch with ohmmeter while opening and closing door.
Connect switch to alarm loop.
