24v SMPS fire alarm vesda system
24V, 5 Amp SMPS for VESDA
Model No. : PS0524NV
The PS0524NV is a fully regulated switch mode power supply providing 24 Volts DC at 5 Amps. The high-frequency action enables it to work smoothly on a very wide AC input voltage range from 90 to 280 volts with comparatively low power losses, high-efficiency small size, and lesser weight.
A 24V SMPS (Switched-Mode Power Supply) fire alarm VESDA (Very Early Smoke Detection Apparatus) system is a type of fire detection and alarm system that uses a 24V power supply and advanced smoke detection technology to detect and alert of potential fires.
VESDA systems are designed to detect smoke at the earliest possible stage, before the fire has had a chance to spread. They work by constantly monitoring the air for smoke particles using highly sensitive laser-based smoke detectors, which can detect smoke at extremely low concentrations.
The 24V SMPS is a type of power supply that converts the incoming AC power to a stable DC voltage of 24V. It is designed to be energy-efficient and to provide a stable power source to the VESDA system.
The VESDA system is connected to a fire alarm control panel which is responsible for the control and management of the system. The control panel receives signals from the smoke detectors and can trigger alarms, automatic fire suppression systems, and other safety measures.
The VESDA system can also be integrated with other building management systems such as HVAC, access control, and CCTV systems, which allows for remote monitoring and management of the system and can help to minimize the risk of fire.
