N505AS
SHORTY MITE MAN DOOR SET
DESCRIPTION
Nascom’s N505AS is a short, 2” block switch, designed for man doors. It
combines the installers’ choice of contact conguration with an N35 NdFeB
magnet for maximum gap performance.
The closed loop version of the N505AS prevents false alarms caused by
warping or shifting of doors, and features our unique NO DEAD SPOT™
technology.
FEATURES
• NO DEAD SPOT™ TECHNOLOGY • 24” ARMORED CABLE LEAD PROTECTION
• EXTRA WIDE GAP - N35 NdFeB RARE EARTH MAGNET • 36” 22AWG WIRE LEADS
• LISTED TO UL634 STANDARD • EXTRUDED ANODIZED (TYPE II) ALUMINUM

INSTALLATION INSTRUCTIONS
NOTE: For N505AS/STHS - red dots on switch and magnet must be aligned for correct operation.
• Position the switch on the door frame and the magnet on the door in desired location.
• Place one of the enclosed spacers under the switch and one spacer under the magnet and align the switch and magnet
housings as close as possible on the door with ¼” gap between the housings.
• Mark the mounting hole locations and drill mounting holes using a drill bit adequately sized for a #6 self-tapping screw.
• Place the spacer under the switch and attach to the door frame using two #6 Self-Tapping screws.
• Place the spacer under the Magnet and attach to the door using two #6 Self-Tapping screws.
• Connect an ohm meter to the switch leads and open and close the door to test switch for correct operation.
• Connect the switch leads to the alarm system.
