EN54-4 approved power supply units from Haydon®

We are proud to announce the launch of our new EN54 PSU Range

EN54-4 compliant power supply range is specifically designed to meet the demands of fire detection and alarm systems, delivering a reliable 27.6V DC uninterruptible power output from a 110–240V AC input. Available in 1A, 2A, and 5A variants, the units are housed in compact or larger metal enclosures to accommodate 7Ah or 18Ah batteries, providing flexible backup options.

Advanced protection features, including overload and deep discharge protection, safeguard both the circuitry and batteries, while intelligent battery monitoring continuously checks for faults such as low voltage, incorrect connection, short circuit, and temperature issues. With voltage-free fault outputs for mains failure and battery status, this range ensures dependable performance and system integrity in critical fire safety applications.
