Von Duprin PS914-4RL-4RL Access Power Supply Dual 4RL

Product Description

The VON DUPRIN PS914-4RL-4RL is an access control power supply configured with two 4RL option boards, designed to provide reliable low-voltage power distribution for electronic access control and door hardware systems. This unit serves as the central power source for electrified locking devices, request-to-exit hardware, and related access control field devices. Electricians and access control technicians install this type of power supply during new construction and retrofit projects where multiple locking circuits require independent, supervised power outputs. The dual 4RL option boards expand the relay output capacity of the base PS914 platform, supporting installations with higher channel counts.

The PS914-4RL-4RL is suited for commercial access control applications where multiple electrified door hardware circuits must be managed from a single power supply chassis. Typical installations include office buildings, schools, healthcare facilities, and other commercial environments using electrified strikes, magnetic locks, or other low-voltage locking devices. The dual option board configuration makes this unit appropriate for larger door schedules where additional relay outputs are required beyond the base unit capacity.

Key Features

• Dual 4RL option boards included for expanded relay output capacity
• Designed for electrified door hardware and access control power distribution
• Supports multiple independent low-voltage locking circuits
• Configured for commercial-grade access control system installations
• Sold as a single unit with option boards factory-integrated

Compatibility

Designed as an OEM-style access power supply for commercial electronic access control systems requiring low-voltage power distribution with relay output expansion via 4RL option boards.

Installation Notes

Installation should be performed by a licensed electrician or qualified access control technician in accordance with NEC requirements for low-voltage power supplies and access control equipment. Disconnect and lock out all power sources before servicing or wiring any connections to the unit. Follow the manufacturer wiring documentation for relay output and input circuit connections. Verify that total connected load on each output circuit does not exceed the rated capacity of the power supply.
