The Norton X-in is designed to operate on the “pull” or “push” side of the door. For “pull” side operation, a rigid arm and slide track assembly is installed. In the closed position, the rigid arm is fully extended into the track assembly. As the arm swings and moves down the track, the door is pulled open. The opening range is from 85 to 110 degrees, with adjustments in equal increments.
For “push” side operation, the installation is similar to a top jamb installation of a door closer. The main arm extends almost perpendicular from the door face. The shoe that mounts onto the arm slide is slightly offset and angled. Reversing the shoe can increase or decrease the closing force. To make the connection between the arm and the operator, the X-in uses a toothed gear to improve the mating connection.
The Norton X-in has six screw holes that run the length of the back plate at the top and the bottom. The lower six screws were installed the back plate onto the metal jamb header.
For this installation the metal jamb header extended proud from the wall by approximately one-half inch. To ensure a solid installation, a piece of ½” plywood was positioned above the jamb header. Then six screws were installed through the back plate, plywood, drywall and into the studs. This way the back plate is plumb. Note: The minimum ceiling clearance for installing the X-in is 5-5/8”.
Once the unit was installed, the next step was to run the wiring and make the connections. The back plate has three connections for the 120VAC - black “hot”, white “common” (neutral) and green ground. The X-in has a built-in Class 2 power supply provides a maximum of 400 mA @ 24VDC. The four connection are “+’, “-“ and “Activation Device” connections. In addition, there is 24VDC available on both the Main Control Unit and the Auxiliary Control Board.
The “Activation Device” connections are used to activate the opening of the door by an external and non-connected source including key switches, push plates and readers.
For this installation, the activation devices are the three push plates and the Touch Less Switch.
24VDC constant power is available on both the Main and Auxiliary Control Boards. The decision was made to wire the Touch Less Switch to the Auxiliary Control Board. The green and white wires from the switch will be connected to the Activation Device connectors on the back plate.
The three push plates are wired in parallel, so when any one these devices is activated, an electrical signal is sent to the Activation Device connection, notifying the X-in to open the door.
For this installation, the push plates are parallel wired from the “IMP” to the “GND” (Ground) on the Main Control Unit connector (IMP is position two) and GND is position number one on the connector. When any push plate is pressed, the circuit closes, sending the signal to release the cylindrical lock latch and to open the door.
To wire the Unlatch for this installation, a power supply and five Amp relay are required. The decision was made to use the Securitron BPS 24-2, a two Amp power supply, as the Unlatch requires 1-1/2 Amp in-rush for 100 milliseconds. The red wire is connected to both the power supply and the common input at the relay. The orange wire, the trigger wire from the Unlatch is also connected to the relay at the Normally Open Input. The black wire is the ground. Only these three wires were used for this installation.
The relay is required to activate the Unlatch. The X-in is not designed for this application. The relay wires are connected to the power wires from the Activation Device on the backplate. The relay is then mounted onto the back plate.
The Touch Less Switch is powered using the “+” and “-“ on the back plate 24VDC power supply. The green wire and the white wire from the switch are connected to the Activation Device connections on the back plate.
Once the wiring is complete, the next step is to program the operator in order to properly open and close the door. The Norton 5900 Series X-in has standard features including Power Assist, Obstruction Detection, Infinite Hold Open, and Power Latch. In addition, the Push and Go feature can be selected for installations when it is advantageous to have the door opened to the full open position when the X-in senses movement of the door.
