Dormakaba Rci DKPS-4A 4A Access Control Power Supply

Product Description

The DORMAKABA USA INC. / RCI DKPS-4A is a multi-output access control power supply designed to provide regulated DC power to electronic access control systems. Rated at 4 amps with a selectable 12 or 24 volt DC output, it distributes power across 8 individually protected outputs, making it well-suited for installations requiring centralized power management. The unit carries ULC listing, confirming it meets recognized standards for safety and performance. Licensed security and low-voltage electricians are the primary installers for this type of equipment.

The DKPS-4A is used in commercial and institutional access control installations where multiple locking devices, readers, or controllers must be powered from a single, supervised source. Its 8-output configuration supports distributed architectures common in office buildings, healthcare facilities, schools, and multi-tenant properties. The fail-safe output designation indicates support for fail-safe locking hardware, which releases upon loss of power — a common requirement in life-safety egress applications.

Key Features

• 4 amp total output capacity supports multiple simultaneous loads
• Selectable 12 or 24 volt DC output voltage for hardware flexibility
• 8 individually protected power outputs for distributed access control devices
• Fail-safe output support for life-safety compliant locking hardware
• ULC listed for verified safety and code compliance

Compatibility

Designed as an OEM-style replacement or new-installation power supply for commercial access control systems requiring regulated 12 or 24 volt DC multi-output power distribution.

Installation Notes

Installation should be performed by a licensed low-voltage electrician or certified access control technician in accordance with local electrical codes and NFPA 70 (NEC) requirements. Disconnect and lock out all AC mains power before wiring outputs or making connections inside the enclosure. Verify total connected load does not exceed the rated 4 amp output capacity before commissioning. Confirm output voltage selection matches connected hardware before applying power.
