Command Access CAT MLRK1-VD – Frequently Asked Questions

1) What Von Duprin exit devices is the MLRK1-VD motorized latch retraction kit compatible with?
The MLRK1-VD works with Von Duprin 33, 35, 98, and 99 series exit devices. Verify your specific exit device model before ordering. The kit provides motorized retraction for the latch mechanism on these rim and mortise exit devices.
2) How does the motorized latch retraction kit work?
The kit uses a motor to automatically retract the exit device latch when activated by an access control signal. This allows the door to be opened without pressing the push bar. The motor activates on command from card readers, keypads, or other access control devices.
3) What voltage does the MLRK1-VD require?
Check the manufacturer specifications for exact voltage requirements. Most Command Access motorized kits operate on low voltage DC power. Connect to your access control power supply according to the installation instructions provided with the kit.
4) Can this kit be used on fire-rated doors?
Fire rating compatibility depends on the specific Von Duprin exit device and door assembly listings. Verify that adding the motorized kit maintains the fire rating of your door assembly. Consult local fire marshal or AHJ for approval on fire-rated applications.
5) Does the push bar still work manually when the motor kit is installed?
Yes, the exit device maintains full manual operation. The push bar continues to function normally for emergency egress. The motorized kit adds remote retraction capability without interfering with manual operation or life safety requirements.
6) What tools are needed to install the MLRK1-VD kit?
Installation typically requires basic hand tools and electrical connections. Follow the manufacturer's installation template and instructions. Some disassembly of the exit device may be required. Consider professional installation to ensure proper operation and code compliance.
7) How do you adjust the latch retraction timing?
Timing adjustments are typically made through the access control system programming rather than the motor kit itself. The kit responds to the duration of the electrical signal from your access control panel. Consult your access control system documentation for timing settings.
8) Will this kit work with both rim and mortise Von Duprin exit devices?
The MLRK1-VD is designed for the specified Von Duprin series which include both rim and mortise configurations. Verify compatibility with your specific model number. The kit adapts to the exit device mechanism regardless of rim or mortise mounting.
9) Can multiple kits be connected to one access control system?
Yes, multiple motorized kits can be connected to a single access control system. Each kit requires its own power and control wiring. Plan your system capacity and wiring runs accordingly. Consider using access control panels with sufficient relay outputs for multiple doors.
10) What happens if power fails to the motor kit?
Power failure does not affect manual operation of the exit device. The push bar continues to work normally for egress. The motorized retraction feature simply becomes unavailable until power is restored. This maintains life safety compliance during power outages.
11) Are there any door weight or size limitations?
Door limitations are primarily determined by the Von Duprin exit device specifications rather than the motor kit. Ensure your exit device is properly sized for the door weight and width. The motor kit works within the existing exit device parameters.
12) How do you maintain the motorized latch retraction kit?
Regular maintenance includes checking electrical connections and testing motor operation. Lubricate mechanical components according to manufacturer recommendations. Test the system regularly to ensure proper response to access control signals. Keep the motor and mechanism clean and free of debris.
