APPLICATION 1<br />
INSTALLATION<br />
PROTECTING PELLA CASEMENT<br />
OR AWNING WINDOWS<br />
Surface Mount Contacts<br />
The miniature size and large number of mounting options available for the Sentrol<br />
1025 series make these switches ideal for protecting Pella casement windows. The<br />
switch and magnet are concealed when the window is closed. Concealed surface<br />
mounting offers benefits over recessed mounting because the construction of<br />
these windows makes recess mounting difficult without breaking the glass.<br />
Important: Pella recommends against mounting switches in sills due to possible<br />
damage from water. If you must drill into the sill, make sure you provide a solid,<br />
tight seal using RTV compound.<br />
Select position of switch and magnet. If ventilation is desired, locate near hinged<br />
side of window.<br />
Drill holes for wires. Slant back at 15˚ to 30˚ to make sure wire will go inside wall<br />
(Figures 1 & 2).<br />
If 1025W wide gap is used, align so that hinge ends of switch and magnet are next<br />
to each other (switch is sensitive to polarity of magnet).<br />
Note: There is nominally 1/2" (1.27 cm) clearance at the widest point between the<br />
bottom or top of window and the sill. Since the widths of the 1025 switch and magnet<br />
with flanges attached are 1/4" (0.635 cm) each, it may be necessary to remove one or<br />
both flanges to allow sufficient clearance to mount switch and magnet.<br />
MOUNTING<br />
METHOD 1:<br />
MOUNTING<br />
METHOD 2:<br />
MOUNTING<br />
METHOD 3:<br />
Mounting with Screws or Nails<br />
• Open switch or magnet so flange is perpendicular to body of switch or magnet.<br />
• Attach with nails or screws through flange.<br />
• Swing body of switch or magnet into flange. Press until body catches on flange.<br />
Mounting with Self-adhesive Tape<br />
• Cut off flange at hinge with diagonal cutters.<br />
• Clean back of switch, magnet, and surfaces where switch and magnet will be<br />
attached with alcohol. Remove backing from tape and attach tape to switch or<br />
magnet, then attach switch or magnet to cleaned surface.<br />
Mounting with Glue, Epoxy, or RTV Mounting Compound<br />
• Cut off flange at hinge with diagonal cutters.<br />
• Attach switch or magnet to surface with glue, epoxy, or RTV mounting<br />
compound.<br />
MAGNETIC CONTACTS<br />
RECOMMENDED<br />
PRODUCT<br />
Attach ohmmeter to switch leads and check for proper operation of switch.<br />
Connect switch to alarm loop.<br />
