INSTALLATION INSTRUCTIONS, continued
TOP MOUNT:
• With the overhead door closed, position the magnet at the top of the door in the desired location, then align the switch under the mag-
net. Adjust the position of the switch and magnet to ensure there is adequate clearance between the housings (1/4” minimum).
• Make sure the stainless steel armored cable will not interfere with the door operation.
• Mark the mounting hole locations for the switch and magnet.
• Drill the marked locations on the door using a high speed drill adequately sized for self-tapping screws or machine screws.
• Drill the switch mounting hole locations using a masonry bit for concrete or cement block walls sized to t expansion anchors for #6
self-tapping screws or use dry wall anchors for sheet rock walls.
• Attach the switch to the wall rst using #6 self-tapping screws and then attach the magnet to the door using #8 self-tapping screws.
• Test the switch by attaching an ohm meter to the switch leads and operate the door.
• Connect the leads to the alarm system conductors.
PART NUMBER SYSTEM
PRODUCT TYPE (1 or 2 digits):
• ST = SWITCH/MAGNET SET
• SW = SWITCH ONLY
• M = MAGNET ONLY
N205AU
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
