This article provides a detailed overview of the installation, testing, and troubleshooting procedures for the Jackson 1285 electrified exit device. The information is derived from manufacturer-provided installation instructions and technical documentation, focusing on the proper setup of motor-driven kits and the associated diagnostic features. The guidance applies to both left and right-hand reverse bevel configurations, as described in the source material.
Installation Overview
The Jackson 1285 is an electrified panic exit device designed for use on aluminum doors with widths of 48 inches. It is available in both left and right-hand reverse bevel configurations. Installation involves mechanical and electrical modifications, including the removal of the existing dogging mechanism and the integration of a motor-driven system. The installation process must be performed with the device removed from the door to ensure proper alignment and functionality.
Corbin Russwin-Yale Installation
The Corbin Russwin and Yale kit (CYLP-UL-M-KIT) is UL Listed and requires no modification to the base exit device. The installation process is as follows:
Remove the Exit Device from the Door:
This is a critical step to ensure that the motor-driven components are properly aligned and secured before the device is mounted.Remove the End Cover from the Bottom Rail:
Access to internal components is necessary for connecting the motor linkage assembly.Attach the Motor Linkage Assembly to the Pushpad Retraction Mechanism:
The motor linkage is connected to the pushpad mechanism, which allows for controlled retraction of the latch.Secure the Aluminum Link:
The aluminum link is fastened using a setscrew and hex wrench to ensure a stable connection between the motor and the pushpad.Install the Motor Assembly:
The motor is positioned behind the linkage assembly and aligned with the mounting holes on the bottom rail.Secure the Motor Assembly to the Rail:
Two Phillips Head screws are used to fasten the motor to the rail, ensuring a secure and stable installation.Connect the MM1 Series Module and Power Supply:
The MM1 Series module is connected to the motor, and the wiring is connected to a 24 VDC regulated power supply. This power source must be stable to ensure consistent operation.Install the Exit Device onto the Door:
The device is mounted onto the door, but the end cover and end cap are left off to allow for testing and adjustment.
Von Duprin Installation
The Von Duprin Motor Driven Kit (VLP-UL-M-KIT) is designed for use with the 99 Series rim panic device. Unlike the Corbin Russwin-Yale installation, this kit requires mechanical modifications to the exit device.
Remove the Exit Device from the Door:
As with all motor-driven installations, the device must be removed from the door to facilitate modifications.Partially Disassemble the Exit Device:
The baseplate assembly is removed from the rail to access the internal components.Remove the Dogging Mechanism Components:
The existing mechanical dogging mechanism must be removed to make space for the motor-driven system.Remove the Rivets Securing the Dogging Mechanism:
A hammer and punch are used to drive out the two rivets that secure the dogging mechanism to the device.Modify the Activation Shaft:
The bar retraction mechanism is held in the depressed position, and the activating rod is cut at the base using a hacksaw. A 9/64" diameter hole is then drilled ½" from the end of the activating rod to secure the motor linkage assembly.Secure the Aluminum Link:
The aluminum link is slid onto the end of the activating rod and fastened using the provided setscrew.Install the Motor Assembly:
The motor is positioned directly behind the aluminum link and aligned with the mounting holes on the rail.Secure the Motor Assembly to the Rail:
Two Phillips Head screws are used to fasten the motor to the rail, ensuring a secure installation.Connect the MM1 Series Module and Power Supply:
The MM1 Series module is connected to the motor, and the wiring is connected to a 24 VDC regulated power supply. This power source must be stable to ensure consistent operation.Install the Exit Device onto the Door:
The device is mounted onto the door, but the end cover and end cap are left off to allow for testing and adjustment.
Testing and Adjustment
Once the motor-driven components are installed, the exit device must be tested to ensure proper operation. The following steps are recommended:
Power the Motor-Driven Latch Pullback:
When the device is mounted onto the door, power is applied to the motor-driven latch pullback. On the initial power-up, the motor retracts the pushpad and the latch mechanism.Check for Full Latch Retraction:
It is important to verify that the latch is fully retracted. If adjustment is required, the potentiometer within the rubberized cover of the MM1 module can be adjusted. Turning the potentiometer clockwise increases the latchbolt travel, while turning it counterclockwise decreases the travel.Test the Exit Device Three Times:
After any adjustments, the exit device should be tested three times to ensure that the latch mechanism operates properly.Ensure the Exit Device is Mounted on the Door During Testing:
The documentation emphasizes that the exit device must be mounted on the door during testing to ensure accurate results.
Troubleshooting and Diagnostics
The MM1 Series module includes on-board self-diagnostics that monitor for overvoltage, undervoltage, and component malfunctions. These diagnostics help protect the motor assembly and MM1 module from damage. In addition to these diagnostics, the device provides audible beeps to indicate specific issues:
- Two beeps indicate overvoltage.
- Three beeps indicate undervoltage.
Four beeps indicate a problem with the travel location switch.
The travel location switch is normally in the closed state. If the switch is faulty or tampered with, the MM1 module will emit four beeps. The module must detect the closed state to function correctly.Five beeps indicate that the latch pullback mechanism is unable to retract completely.
This can occur when the motor cycles and the switch does not change state to the open position. Potential causes include tampering with the pushpad, a switch that has not changed states, or the aluminum link not traveling far enough to depress the switch.Continual beeps indicate that the pushpad is being obstructed and the mechanism cannot reset.
To reset the pushpad, it must be depressed until the beeping stops. Releasing the pushpad allows the system to reset and return to the dogged condition.
Power Supply Requirements
The power supply requirements vary depending on the type of kit used:
Motor-Driven Kits:
Pushpad exit devices using the Command Access motorized kits can be powered using any 1A or greater 24VDC regulated power source. A stable power supply is essential for consistent operation.Solenoid-Activated Kits:
Pushpad exit devices using the Command Access solenoid-activated kit can be powered using the Command Access PS1N linear power supply. The UL Listed PS1N delivers 24VDC and provides sufficient power for the in-rush requirement of one solenoid-activated electric pullback.
Final Assembly
After all adjustments and tests are completed, the end cover and end cap are installed to protect the internal components. It is important to test the latch pullback one final time to ensure that the device operates as intended.
Conclusion
The Jackson 1285 electrified exit device offers a reliable and secure solution for controlled egress in commercial and institutional settings. Proper installation, testing, and troubleshooting are essential to ensure that the device functions correctly. The installation process varies depending on the type of motor-driven kit used, with the Corbin Russwin-Yale and Von Duprin kits requiring different modifications to the exit device. The MM1 Series module provides both on-board diagnostics and audible beeps to assist with troubleshooting, making it easier to identify and resolve issues. A stable power supply is critical for consistent operation, and users are encouraged to follow the manufacturer’s guidelines for installation and maintenance.
