The Agni 405 LED Sounder Cum Strobe is designed to do one simple but critical job, make sure people can quickly see and hear an emergency alert. It combines a loud audible alarm with a bright LED strobe light, making it highly effective in indoor fire alarm systems where visibility and sound both matter. Built using high-quality ABS (Acrylonitrile Butadiene Styrene) plastic, the device is strong, durable, and reliable for long-term use.
This sounder cum strobe works especially well in places where noise levels are high, like factories, commercial buildings, or public spaces. It also helps improve safety for people with hearing impairments by providing a clear visual alert through its LED strobe light, ensuring no one misses an emergency warning.
The device operates on 12V/24V DC (up to 36V ±6%) and delivers a powerful sound output of 95–100+ dB. It supports different alert tones for fire and security situations, with sound frequencies ranging from 500Hz to 2000Hz. Along with this, the built-in LED strobe light produces 95–108+ candela intensity and covers a wide 120° area, making the alert easily visible across rooms and corridors.
It follows the standard Temporal-Three (T-3) alarm pattern, which is widely recognized for fire evacuation signals. With a high-frequency piezo disc and integrated circuit design, this fire alarm sounder performs consistently whenever it is needed.
The Agni 405 also meets important safety standards like EN 54-23, IS 2189, UL 1971, UL 464, NFPA 72, NBC, and BIS, making it a reliable choice for fire safety systems, emergency notification setups, and indoor alarm installations.
