Installation
The Model 126 is designed for use with tungsten filament bulbs of 150-watt rating or
less at 120 volts.
1. Using the following guidelines, determine a suitable mounting location:
• The switch and actuator must be within the listed sense range. See Ordering/
Electrical Specifications.
• The actuator must be aligned with the switch—labels facing the same direction.
(See Figure 1.)
Important: When mounting in proximity to ferrous material (steel), the sense
range can be reduced 50% minimum depending on the shape and type of
material. Test the switch in specific applications to determine the actual
sense range.
2. Determine location of switch on door jamb. To ensure proper operation and that the
magnetic field not interfere with switching, do not locate closer than six inches
from hinge side of door.
3. Locate switch (B) and magnet (A) locations on door jamb and door. (See Figure 2.)
Drill a one-inch hole to accomodate these. (Do not hammer. This can damage the
switch.) Misalignment of up to 1/2-inch can be tolerated, but not in a ferrous metal
door. (To check if a door or jamb is ferrous hold a magnet to it. If it is attracted
it is ferrous.)
4. Connect the black line conductor, see Figure 3, to the fuse and fuse holder that are
provided. Connect the white neutral conductor to the load. Connect the flexible
conduit to a NEMA Type I enclosure, see Figure 2.C, using a properly sized and
acceptable 3/8 inch flexible conduit connector. If the switch is being used in a
branch circuit, connect to a UL listed relay with minimum rating of 120VAC/15A.
5. The switch and actuator must move in one of the approved directions.
See Figure 4.
Warning! To avoid switch failure determine the actual load of the switch circuit and
take steps to protect the switch from voltage spikes, current inrush and line/load
capacitance using the following recommendations.
• Surges from coils, motors, contactors, solenoids and tungsten filaments. Transient
protection, such as back-to-back zener diodes (Transorb) or an RC network, is
recommended for such loads to ensure that maximum ratings of the switch are
not exceeded.
• Line capacitance and load capacitance. An in-line resistor can be added in series
immediately before the load to limit the inrush current. The resistor can only be
added in series with the last wire just before the load. The voltage drop and the
power rating of the resistor must also be calculated as follows:
Voltage drop = I • R
Watts = I
2
• R
( I = maximum continuous current of the load)
To verify switch operation with an ohmmeter:
Set range at 20 mega ohms (switches with triac output, set ohm range at 20 kilo
ohms). For a normally open switch, the meter will read a high impedance with the
actuator away. It will read very high to infinity range (triac switches will read high kilo
ohm to infinity range) with the actuator within sense range. You will see the opposite
reading for a normally closed switch.
