AES EN54-4 uninterruptible 24 V power supply for fire alarm systems
Country: France · Model: AES24M5 / AES24M10
This wall-mounted 24 V DC uninterruptible power supply for fire alarm and voice alarm systems complies with EN 54-4. The output current is 5 A for AES24M5 or 10 A for AES24M10. The unit is fed from a 230–277 V AC mains and keeps the load running from its own batteries.

Description
The device has two independent protected outputs, so the supply of the control panel and the alarm sounders can be separated. The enclosure holds 9, 12 or 18 Ah batteries, and for longer autonomy an external battery box of up to 45 Ah is fitted. Charging follows the IUoU characteristic with temperature compensation, which extends the life of lead-acid batteries in unheated rooms. The internal resistance test reveals battery degradation before the system loses its reserve. The IP30 protection degree is intended for dry rooms, with wall mounting. Compliance with EN 54-4:1997+A1+A2 is required for acceptance of fire protection systems.
How to choose
The model is determined by the total current consumption of the fire system in standby and alarm modes. Up to 5 A, AES24M5 is enough; above that take AES24M10. Battery capacity is calculated from the required standby and alarm time, and if 18 Ah in the enclosure is not enough, add an external box of up to 45 Ah. This device is not suitable for AC supply of server or IT equipment, which needs online UPS units of the IRIS series.

FAQ
What is the output current of AES24M10?
AES24M10 delivers 10 A at 24 V DC, and the smaller model AES24M5 delivers 5 A.
Which batteries are fitted in AES EN54-4?
The enclosure takes 9, 12 or 18 Ah batteries, and with an external box the capacity is increased to 45 Ah.
What mains does AES24M5 run from?
The input voltage is 230–277 V AC, so the device works from the phase voltage of an ordinary mains.
Can AES EN54-4 be installed in a damp room?
The IP30 protection degree does not protect against moisture, so the device is wall-mounted in dry rooms.
How does AES EN54-4 monitor battery condition?
The charger works to IUoU with temperature compensation and periodically performs a battery internal resistance test.
