Norton Creates A Safe Zone

As the SafeZone was positioned against the header, the cable was slid through the base plate. Loctite® Threadlocker Red 271™ was used on the seven ¼-20 screws prior to installation.

With the unit installed onto the header and the adjustable arm onto the door, the main arm is placed onto the spindle with the arm mark aligning with the pinion flat. The arm screw and arm washer secure the main arm to the spindle. The adjustable arm is positioned perpendicular to the door in the closed position.

Once the unit is mechanically installed, make any adjustment to closing force, the latch, sweep and backcheck in order to properly close the door. Adjustment instructions are printed on the inside of the cover. Once the mechanical portion of the door closer is adjusted, the next step is to provide power.

Connect the cable red, green and black wires to the input circuit board. The maximum wire gauge the SafeZone connector will accept is 18 AWG. Connect the wires to the power supply. The motion sensor red LED will illuminate when initially powered and when someone is detected until movement is no longer detected.

The final step is to set the detection area. The sensor can be adjusted from horizontal (0 to 45 degrees), and 15 degrees to the left or right. The detection area can be in three positions. When the motion sensor is horizontal, it covers both sides of the door. When the sensor is at 30 degrees, the detection area extends from vertical out to approximately 30 degrees. When the sensor is at 45 degrees, the detection area extends from vertical out to approximately 45 degrees, 50 percent farther.

The installation, traffic flow and physical abilities of the people determine the position and size of the sensing field and the hold open time. The size of the detection area is determined by the height at which the SafeZone is installed from the floor. The motion sensor mounting height is from a nominal of seven feet to a maximum of ten feet.

Hold open time is the time the door will remain open after movement is no longer detected. It is adjustable from 0.5 seconds to 20 seconds. The default time is ten seconds. According to Norton, the average person requires approximately five to seven seconds to walk through the doorway. A person with a cane may require eight to 14 seconds. A person in a wheel chair may require 16 to 20 seconds.

Time adjustments can be made by pressing and releasing the up or down buttons on the right side of the motion sensor assembly. To reset the hold open time to the default time, press both of the push buttons simultaneously for three seconds.

Test the SafeZone to be certain the system is operational with a sufficient hold open time. Make any adjustments necessary. Once the system is operating properly, install the cover.

Norton has included yellow and black print stickers to be installed onto both sides of the door notifying people this door will close automatically.

The SafeZone warranty is two years.
