The Norton 7200 Series Multi-Point Hold Open is a door closer designed for both pull-side and push-side applications, offering controlled door operation with a hold-open feature. It is suitable for various door types and environments, providing adjustable closing force, speed, and backcheck.

Function Description

The 7200 Series operates as a hydraulic door closer with an integrated hold-open mechanism. For pull-side applications, it utilizes a slide track, while push-side applications employ double lever arms. The device controls the door's opening and closing cycles, preventing it from slamming shut and allowing it to be held open at a desired angle.

The closer incorporates several adjustable controls to fine-tune its performance:

Closing Speed Controls: "S" (Sweep) valve regulates the speed from full open to 5 degrees, and "L" (Latch) valve controls the speed from 5 degrees to closed. These allow for precise management of the door's closing motion.
Opening Cycle Controls: "B" (Backcheck) valve adjusts the strength of cushioning in the backcheck range, preventing the door from opening too rapidly or forcefully. The "P" (Backcheck Position) valve adjusts the angle at which backcheck is engaged during the opening cycle.
Closer Spring Adjustment: This feature allows for increasing or decreasing the closing force, ensuring the door closes consistently while accommodating factors like latching hardware, air pressure, or frame issues. For instance, a closer set to ADA-required 5 lbs opening force might need adjustment to ensure proper closing.
Selective Hold Open Cam Adjustment: This mechanism enables the door to be held open at a specific, desired angle. Once the door is opened to the chosen angle, the cam can be adjusted to engage a switch, holding the door in that position. The hold-open feature can be disengaged by forcing the door out of the hold-open position by closing it.

The device can be integrated with various electrical connections, including non-detectored, detectored, and RF remote receiver units, allowing for automated or remote control of the hold-open function.

Usage Features

The 7200 Series is designed for ease of installation and versatile application:

Handed Units: The units are handed, meaning the hand of the unit must match the hand of the door for proper installation and function.
Door Compatibility: It is compatible with doors hung on ball bearing butt hinges or 3/4" (19mm) offset pivots, and suitable for door thicknesses ranging from 1-3/4" (44mm) to 2-1/4" (64mm).
Frame Requirements: A minimum frame face of 2" (51mm) is required.
Ceiling Clearance: Specific ceiling clearances are needed: 3-1/2" (89mm) for push-side applications and 4" (102mm) for pull-side applications, as detailed in the provided templates.
Smooth Operation: Before installation, it's crucial that the door swings freely through its entire opening and closing cycle to ensure optimal performance of the closer.
Auxiliary Door Stop: For push-side applications, an auxiliary door stop (provided by others) is required. For pull-side applications with an opening angle greater than 125 degrees, the spring cushion stop cannot be used, and an auxiliary stop is necessary.
Electrical Integration: The closer can be connected to various electrical systems, including stand-alone wiring, smoke detectors, and RF remote receiver units, enhancing its functionality for different building requirements. Power input must match the voltage stated on the unit (24V or 120V).
Surface Mount Power Input: The design allows for surface-mounted power input, with provisions for strain relief and a cover that faces the ceiling. For surface-wired installations, a shaded area on the cover can be removed, and cut edges should be repainted to prevent corrosion.
RF Remote Receiver Units: When integrated with RF remote receiver units, the device offers programmable hold-open functions via DIP switch settings (Pulse Relay or Toggle Relay) and hand-held configuration. This allows for flexible control over the hold-open duration (0.5 sec or 10 sec hold time in Pulse Mode) and activation method. Push plate configuration is also supported for activating the transmitter.

Maintenance Features

The 7200 Series is designed with maintenance considerations to ensure long-term reliability:

Hydraulic System: The closer utilizes a hydraulic system for smooth operation. It is important not to remove the valves from the closer, as this will cause hydraulic oil to escape, leading to malfunction and requiring professional repair.
Backcheck Valve: The "B" (Backcheck) valve should never be completely closed, as it is not intended to provide a positive stop and doing so can damage the unit.
Cam Screw Tightening: When adjusting the selective hold-open cam, the cam screw should be tightened firmly but not overtightened, as this can cause damage to the cam.
Wiring Requirements: All wiring connections must conform to local wiring codes, and the maximum wire size is 18AWG. Proper wiring is essential for safe and reliable operation, especially for detectored and RF units.
Troubleshooting Guide: The manual includes a troubleshooting section to address common issues such as the door not holding open, holding open at the wrong angle, or not closing. This guide helps identify probable causes (e.g., no power, loose connections, cam switch issues, wiring errors) and suggests corrective actions.
RF Unit Troubleshooting: Specific troubleshooting steps are provided for RF remote receiver units, covering issues like the red LED flashing without programming the receiver, or intermittent signal reception. These include checking for stuck push plates, faulty transmitters, or insufficient antenna wire length.
Environmental Considerations: The unit is designed for interior mounting in a dry environment with a maximum humidity of 95%. Adhering to these conditions helps prolong the device's lifespan.
Regular Inspections: While not explicitly detailed as maintenance, the emphasis on ensuring the door swings freely before installation implies that periodic checks of door movement and hardware could prevent issues.
Professional Support: For problems not listed in the troubleshooting guide, contact information for technical product support is provided, indicating that professional assistance is available for complex issues.
