N115
1/4 INCH RECESSED WIDE GAP STUBBY PRESS FIT SWITCH SET - FLANGED
DESCRIPTION
The N115 is a ¼ inch diameter flanged recessed press fit wide gap switch set
with a ¼ inch X ¾ inch bare rare earth magnet. The N115 is designed for narrow applications where drilling space is limited.
The N115 is the installer’s choice of contact configuration where drill depth is a
consideration and excellent air and side-to-side gaps are required to stop false
alarms, caused by shifting or warping doors and windows.
FEATURES
• Slim design • Reduced false alarms
• Encapsulated hermitically sealed contacts • Polypropylene housing
• Press-fit flanged no glue required • 12 inch 22 AWG wire leads
• Wide gap - N35 NdFeB rare earth magnet • Listed to UL634 standard

INSTALLATION INSTRUCTIONS
• Mark the desired location for the switch and magnet on the top edge of the door and door frame making sure your marks
are in alignment.
• 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 ¼” 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 ¼” hole in the door frame.
• Apply adhesive or RTV to the end of the magnet and 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 system for correct operation.
