Steel or aluminum revolving doors can be secured in several ways, depending<br />
upon their material and the availability of mounting space.<br />
For doors accessible from the top: Lock door to check its position when<br />
secured. Mark top, side or floor where you will place the switch.<br />
Place switch in top or canopy of the assembly. Offset it slightly as magnet will be<br />
positioned on side of door. Drill a 15/16" (2.38 cm) diameter hole. When mounting,<br />
use RTV mounting compound (Figure 1).<br />
Place magnet on door as close to rubber gasket as possible (Figure 1). Observe<br />
Polarity. If mounting magnet on steel, use spacer or order a special magnet<br />
containing two magnets inside the housing. When using a surface mount magnet<br />
with the 1078W, position the left end of the magnet as you read the logo, centered<br />
off the end of the switch (Figure 3).<br />
For doors NOT accessible from the top: Mount switch on side of door in wall<br />
(Figure 3).<br />
Another mounting method is to bury the switch in the floor and mount the magnet<br />
to the bottom of the door (Figure 2).<br />
Note: Some systems incorporate an electro-magnetic break-away device, usually<br />
located in the drum. Locate the magnetic contact far enough away to prevent<br />
adverse effects to magnet. Stainless steel armored cable is available if the switch<br />
will be exposed. Consult factory.<br />
