Dycon 24VDC 1A Switched-Mode Power Supply for Magnetic Fire Door Holders (D2401-AA)

The Dycon D2401-AA power supply unit is specifically designed to provide reliable power to magnetic fire alarm door retainers and various other 24 Volt DC applications. It operates on a switched-mode system and delivers a steady 24VDC output, which is crucial for effectively powering highly inductive loads like magnetic door retainers. This eliminates the need for additional control relays and greatly reduces the risk of electrical spikes that can cause disruptions, delays, and costly service calls.

Switched-mode system for stable power delivery

Housed in a compact yet durable steel casing, the D2401-AA power supply unit boasts an attractive design. It features an externally visible status LED, allowing for easy monitoring of its operational status. This visual indicator is useful for quickly identifying any potential issues or malfunctions. Moreover, the unit includes a normally closed (NC) volt-free opto-relay output, which enables remote signalling of its status and serviceability.

Remote signalling and communication with opto-relay output

The opto-relay output can be utilised to indicate problems either locally or remotely. It serves as a means of communication with a Fire Alarm panel or a suitable signalling device. Connecting this output to a centralised monitoring system, such as a Fire Alarm panel, can promptly identify and address any operational issues with the power supply unit. This feature enhances the overall safety and efficiency of the system, minimising the risk of personnel delays and ensuring a timely response to any potential incidents.

Intelligent protection technology for system reliability

To protect against system downtime, the D2401-AA incorporates Dycon's intelligent electronic fuse technology with automatic reset. This innovative feature enables the power supply unit to recover automatically from any faults or malfunctions, reducing the need for manual intervention and minimising disruption to the system's operation. Furthermore, the unit incorporates Dycon's unique protective technology, which includes intelligent and capacitive load switching, surge protection, and snubbing. These features ensure stable and secure power delivery, safeguarding both the power supply unit and the connected devices.

Substantial load capacity for multiple door retainers

The D2401-AA power supply unit is capable of handling a substantial load, making it suitable for powering up to 8 double doors with a total of 16 magnetic door retainers. With each magnetic door retainer typically requiring 50 mA of power, the unit's 1A output provides sufficient capacity for the reliable and efficient operation of the connected devices. Whether it's for magnetic fire alarm door retainers or other 24 Volt DC applications, the Dycon D2401-AA power supply unit offers a robust and versatile solution.
