Power supply for fire protection systems EN54C 27.6V/5A/2×65Ah EN54C-5A65

Power supply for fire protection systems – reliable power in crisis situations

This advanced buffer power supply, with a voltage of 27.6V and a current of 5A, is designed to work with fire alarm systems, smoke and heat control systems, and other devices requiring a stable power supply. It ensures uninterrupted operation of these key safety elements, even in the event of a power grid failure. Thanks to the possibility of connecting two 65Ah batteries, it guarantees a long-lasting backup power supply.

Design and functionality

The power supply is characterized by a solid construction – the housing is made of steel sheet (RAL 3001), which ensures durability and resistance to mechanical damage. The dimensions of the device (410 x 648 x 180 mm + 8mm distance from the ground) allow for easy surface mounting. Inside there is space for two batteries, and the power supply itself is equipped with protections against short circuit (SCP), overload (OLP), overvoltage (OVP), undervoltage (UVP) and has a tamper – protection against opening the housing. Additionally, it has technical outputs signaling AC power failure (EPS) and total failure (ALARM) as well as an input for an external failure signal (EXTi).

Compliance with standards and safety

The device meets stringent safety standards, including the fire standard EN54-4 and EN12101-10. It has a CNBOP-PIB certificate of conformity No. 1438-CPR-0628 and a CNBOP-PIB approval certificate No. 5222/2024. This confirms its reliability and effectiveness in ensuring fire safety. The battery charging current is 2.6A, and the device efficiency is 87%.

Practical application and benefits

• Safety: Ensures the continuity of fire protection systems in the event of a mains power failure.

• Compliance with regulations: Meets the requirements of EN54-4 and EN12101-10 standards, which is crucial for installations in public facilities.

• Easy installation: Surface mounting design makes installation and servicing easier.

• High reliability: Solid construction and protections protect against damage and ensure long-term operation.

• Status signaling: Built-in EPS and ALARM technical outputs allow for quick identification of power or system problems.

• Versatility: Compatibility with AGM or gel batteries provides flexibility when choosing components.

• Long-lasting operation: Two 65Ah batteries provide a long backup power supply time.

This power supply is an investment in safety – a reliable power source for fire protection systems that can save lives and property.
