The primary task of power supplies for fire protection equipment is to ensure continuity of energy supply. The main power supply function is provided by connection to the AC mains. The backup power supply is provided by a battery pack (appropriately selected for the load).
The Hyfire HFW-PSU2-03 is an EN54-4 approved 24V 2A power supply ideal for use in fire and smoke and ventilation control systems. It provides compliant power supply/continuity to the Taurus expanders and features battery deep discharge protection in the event of a prolonged mains failure.
At Elmdene, we understand the importance of using high-quality components in our fire and security protection power supply units (PSUs). Capacitors and Field Effect Transistors (FETs) are two key components that must be carefully considered for their quality, longevity, design, and integration.
Fire and security systems are essential for protecting properties and ensuring the safety of occupants, and the power supply units (PSUs) play a critical role in their functionality. Therefore, choosing a high-quality PSU built for reliability and longevity is crucial for the system's success.
Find out more EN54 is a mandatory fire detection and fire alarm system standard and refers to compliant power supply equipment for fire detection and fire alarm systems. To comply with EN54-4 (the power supply component), Elmdene products are evaluated and tested by an independent, 3rd party notified body.
When selecting a PSU for your fire protection or security system, it's important to consider the PSU's design and quality control. The overall design of the PSU should consist of high-quality components that are assembled reliably.
