PROTECTING THIN FRAME WINDOWS<br />
APPLICATION<br />
INSTALLATION<br />
RECOMMENDED<br />
PRODUCTS<br />
Securing Pella or sliding aluminum windows or doors which have thin window<br />
frames and limited space for mounting the switch. Sentrol’s 1145-W ultraminiature<br />
surface-mount magnetic contact, with regular or wide gap operating<br />
distance, is ideal for this application.<br />
Determine best position for switch and magnet. Magnet will be mounted on frame<br />
of glass.<br />
Switch and magnet are mounted with very high bonding tape, silicon glue or brass<br />
brads, depending upon the frame material.<br />
Clean surface with alcohol for good adhesion.<br />
For wide gap versions, switch and magnet must be mounted with mounting holes<br />
to the “outside” in “four-corners” position (Figure 1), with Sentrol logo on switch<br />
and magnet reading from left to right. This assures proper polarity. Wide gap<br />
operating distance is 3/4" (1.9 cm) for 1145W model.<br />
