N75

3/8” RECESSED STANDARD DOOR CONTACT SET

DESCRIPTION

Nascom’s N75 Series standard length 3/8” recessed contact protects all nonferrous (e.g. wood, aluminum and vinyl) doors and windows in both residential and commercial settings.

The N75 is the installer’s choice of contact configuration where drill depth is not a concern and maximum air and side-to-side gaps are required to prevent false alarms caused by shifting or warping doors and windows.

FEATURES

• PRESS FIT - NO GLUE REQUIRED	• ENCAPSULATED HERMETICALLY SEALED CONTACTS
• 12” 22AWG WIRE LEAD	• POLYPROPYLENE HOUSINGS
• WIDE GAP - N35 NdFeB RARE EARTH MAGNET	• LISTED TO UL634 STANDARD

INSTALLATION INSTRUCTIONS

•Mark location for the switch on the door frame and mark the location for the magnet on the top edge of the door.

•Make sure switch and magnet hole locations are aligned.

•Using a square, transfer the marks on to the top edge of the door and the opposing door frame.

•Using a tape measure or graduations on the square, locate the center of the door edge and place an intersecting line with the first mark. Drill a 3/8” hole at the location where the marks intersect.

•Repeat the above step to locate the hole position for the switch in the door frame. Drill a 3/8” hole in the door frame.

•Press the magnet into the hole you drilled in the door until flush with top edge of door.

•Connect the switch leads to the alarm system. Caution! Hold wire leads, not the switch housing while cutting and stripping to prevent damage to switch.

•Insert wire leads into hole followed by the switch and press the switch into the hole until the head is flush with the door frame

•Test switch for correct operation and make sure gap performance is acceptable.
