Introduction
The Milleteknik EN54 Series power supplies are designed for fire alarm systems and security facilities requiring reliable 24 V DC power. These units convert 230 V AC mains voltage to 24 V DC, ensuring continuous operation of critical systems even during power outages. The series includes models certified to EN54-4 and approved for SBF 110:8 standards, making them suitable for demanding safety applications.
The product range includes models with varying current capacities: EN54 24V 5A FLX M, EN54 24V 10A FLX M, EN54 24V 15A FLX M, and EN54 24V 25A FLX M.
Important Safety Information
⚠️ READ THIS FIRST! 100 mm free space must be left on the top and bottom. Ventilation must not be covered. Electronics are intended for use in a controlled indoor environment. Mains voltage should be disconnected during installation. It is the installer's responsibility to ensure the system is suitable for its intended use. Only authorized persons should install and maintain the system. All information is subject to change.
ℹ️ ABOUT GLASS TUBE FUSES ON CERTIFIED DEVICES Glass tube fuses on the circuit board's load outputs have a tripping time of approximately 150 ms. If a fuse trips on one load output, the voltage on all load outputs drops to 0 V for 150 ms. The installer must ensure an energy buffer of at least 150 ms in systems powered by this battery backup.

- A ferrite on EN54 units should be threaded one pass on load cables (A).
- A ferrite must be threaded one pass on the mains power cable (B).
PCB Description of PRO2v3
The motherboard controls the device, distributes power, and communicates with other systems. See technical data for more information.
6.1. Fuses
The PRO2 v3 circuit board has several fuses:
| Fuse | Type | Explanation |
|---|---|---|
| F1 | T16A | Mains fuse |
| F2 | T2A | Load fuse 2 + (for P2: 4) |
| F3 | T2A | Reading protection 1 + (for P2: 1) |

| F5 | T16A | Load fuse 1+ (for P2: 2) |
⚠️ FUSE REPLACEMENT WARNING (A) There is a risk of damage if a fuse is replaced with one larger than the original. Fuses protect the connected load and cables against damage and fire. It is not possible to change a fuse to a larger one to increase power output.
Connecting the Mains to the Motherboard (PCB)
6.2.1. Connect mains
Pull wiring through the cabinet's cable entry. Secure the mains cable with cable ties where possible. Keep electrical network cabling separate from other cabling to avoid EMC interference.
Connect the mains cable to the terminal block before re-installing the motherboard. Secure F (Phase) and N (Neutral) with cable ties for electrical safety.
| Letter | Phase | Neutral | Protective earth |
|---|---|---|---|
| F | Phase | ||
| N | Neutral | ||
| PE | Protective earth |
ℹ️ ELECTRICAL MAINS CONNECTION 230 V AC ON CIRCUIT BOARD Check that the marking on the circuit board matches the cable arrangement on the terminal block.
6.3. Connect load
⚠️ MAX CURRENT The maximum current must not be exceeded. Max current is indicated on the device's nameplate.
Load connections are made on the motherboard (P2:1-4) for 5 A and 10 A units. For units with higher currents (15 A - 25 A), load must be connected via a power board or an optional board (effect card).
| Circuit board number | Explanation |
|---|---|
| P2: 1 | Connection for load 1 + |
| P2: 2 | Connection for load 1 - |
| P2: 3 | Connection for load 2 + |

⚠️ CAUTION Load may only be connected to the motherboard in 5 A and 10 A units. For other units, load must be connected via a power board or option board.
6.4. Connection of load 15 A - 25 A units
For units with an effect card (available for higher currents), the load must be connected on an optional board. Refer to the option board documentation for connection details.
⚠️ WARNING Load must not be connected to the motherboard if the device is 15 A or 25 A, as it will be destroyed during commissioning. Motherboards faulty due to incorrect connections are not covered by warranty.
6.5. Load cards with blade fuses
Load cards replace the motherboard's load output and feature easier-to-change fuses and simplified load connection.
| No. | On circuit board | Explanation |
|---|---|---|
| 1, 9 | FUS2, FUS4 | + fuse, 10 A- 25 A depending on the product. |

The dip switch offers several configuration modes:
| Dip switch | In mains operation or in battery operation | Comment |
|---|---|---|
| 1 | Address for external communication. | - |
| 2 | Address for external communication | - |
| 3 | Address for external communication | - |
| 4 | Address for external communication | - |
| 5 | Sets alarm for mains failure delay | Available from software v1.5 |
| 6 | Sets alarm for mains failure delay | Available from software v1.5 |
| 7 | Sets alarm limit for low battery voltage in battery operation. | Available from software v1.5 |
| 8 | Turns LED off or on. | Upcoming feature through software update |
| 8 in sequence | Performs battery test | Not available in NEO. |
6.6.1. Mains failure delay (dip 5-6)
Configure the delay time for the mains failure alarm:
| Alarms for mains failure are given after: | Dip 5 | Dip 6 |
|---|---|---|
| 3 seconds | OFF | OFF |
| 30 minutes | ON | OFF |
| 60 minutes | OFF | ON |
| 240 minutes (4 hours) | ON | ON |
6.6.2. Low battery voltage (dip 7)
Dip 7 controls the low battery voltage alarm setting:
| Alarm for low battery voltage is given when | Dip 7 |
|---|---|
| 22.8 V* | ON |
| 24 V | OFF |
*25% of battery capacity remains.
6.6.3. LED (dip 8)
The LED and battery test function are controlled by dip 8. The LED is always lit when the door is open. Dip-switch 8=ON turns off the LED; Dip-switch 8=OFF turns on the LED.
6.6.4. Battery test (dip 8)
To perform a battery test, change the position of dip 8, wait 5 seconds, and then switch it back. The test initiates after 3-8 seconds and lasts about 6 seconds. The LED will flash yellow quickly. Aged battery alarms may be indicated during the test. Reset dip 8 only after the test is complete.
- If dip 8 is OFF: Switch to ON (wait 5s), then back to OFF.
- If dip 8 is ON: Switch to OFF (wait 5s), then back to ON.
6.7. Reboot to confirm changes in address, battery and alarm settings to parent system
After setting parameters via dip switches, restart the device software for changes to take effect. Rebooting does not interrupt output voltage.
Restarting is done by jumpering J13 (PRO2). Reboot must be performed after every change. NEO cannot be connected to communication/UC during reboot.
6.8. Alarm card for PRO2
The alarm card provides relay outputs for various alarms. All fault alarm relays should be in a drawn state (gap between CO and NC). All relay outputs are normally live and signal an alarm when voltage is absent.
