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.
PART NUMBER SYSTEM
PRODUCT TYPE (1 or 2 digits):
• ST = SWITCH/MAGNET SET
• SW = SWITCH ONLY
• M = MAGNET ONLY
N505AS
BUILT-IN END OF LINE RESISTOR VALUE (zero to 4
digits):
• Blank = No built-in end of line resistor
• All other resistor values are specied (e.g. 1K
= 1,000 Ω)
LEAD WIRE COLOR (zero to 2 digits):
• Blank = Switch Color except:
» resistor contacts standard is red wire
» all 2 conductor jacketed wire is grey
• BL = Blue leads
• OL = Orange leads
WIRE TYPE (0 or 1 digit):
• Blank = UL1061 | 22AWG | 7/30
• J = 2-conductor PVC Jacketed NEC Type
CL2 and CM
CIRCUIT (0, 2 or 3 digits):
• Blank = CLOSED LOOP
• 2CR = DUAL CLOSED LOOP
• FB = OPEN LOOP
• SD = SPDT
• DD = DPDT
• HS = HIGH SECURITY
LEAD LENGTH (zero, 3 or 4 digits):
• Blank - 24 Inches
• All other lengths specied in
Inches with 3 digits (e.g. 036 =
36 Inches)
* lead length is armored cable length-
wire length is 12 inches greater
than armored cable length
END OF LINE RESISTOR (zero to 4 digits):
• Blank = Resistor in series with the switch
• P = Resistor in parallel with the switch
• SP = Resistor 1 in series to the switch; resistor
2 in parallel to the switch
