Part Number: AGNI-405-LED | Category: Sounder
Description
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.

Step-by-Step Sounder Cum Hooter LED Working Principle?
01
Signal Activation from Fire Alarm Panel
When a fire alarm system detects smoke, heat, or manual trigger activation, it sends an electrical signal (12V/24V DC) to the sounder cum strobe unit.
02
Instant Audible Alert
The device immediately produces a loud alarm sound of 95-100+ dB, using a high-frequency piezo disc. This ensures people can hear the warning even in noisy environments.
03
LED Strobe Flash Activation
Simultaneously, the LED strobe emits high-intensity flashes (95-108+ candela) with a wide 120° coverage, providing strong visual alerts.
04
Standardized Alarm Pattern
The sound follows the Temporal-Three (T-3) pattern, which is globally recognized for fire evacuation. This pattern helps occupants quickly identify the emergency.
05
Continuous Alert Unit Reset
The device continues both sound and light alerts until the system is manually reset or the emergency condition is cleared.
06
Dual Safety coverage
By combining sound and light, the device ensures alerts reach: People in loud environments, Individuals with hearing impairments, Areas with limited visibility.
