Surface Mount <strong>Application</strong>s<br />
Five methods are presented here for protecting deeply recessed doors with surface<br />
mount contacts. Note that when mounting on steel, a spacer should be used<br />
behind the switch, and/or a wide gap switch should be used.<br />
Method 1: Magnet with Spacers<br />
Sentrol has a range of spacers available for each contact series. Stack spacers until<br />
magnet aligns with switch when the door is in the closed position.<br />
Method 2: Switch on Inside of Jamb<br />
This is a desirable mounting technique because no brackets are required. Use only<br />
on a door with a reliable stop so that the door cannot swing inward and hit the<br />
switch.<br />
Method 3: 1082, 1085T, or 1045T Series with Bracket<br />
Verify that the distance from the inside of door frame to inside of door does not<br />
exceed 1" (2.54 cm). If over 1" this application cannot be used — use Methods 4<br />
and 5.<br />
1082W or 1085TW with 1910 bracket, or 1045T with 1910-2 bracket<br />
