Description

The Agni 418 High Intensity hooter is a heavy-duty audible warning device designed to deliver immediate alarm signals during fire emergencies or critical alarm conditions. It integrates seamlessly with 24V DC conventional fire alarm control panels, ensuring reliable operation across a wide range of applications. 

When an alarm is triggered by smoke detectors, heat detectors, or manual call points, the fire alarm panel activates the hooter circuit. The internal solid-state electronics generate a pulsed dual-tone alarm signal, which drives the built-in loudspeaker to produce a highly audible warning sound. 

With sound output reaching up to 115 dB, the device is capable of delivering clear alarm signals across large areas such as manufacturing plants, warehouses, commercial complexes, hospitals, and residential buildings.

The hooter is constructed using a robust steel-metal enclosure, protecting the internal components from vibration, dust, and physical impact commonly present in industrial installations. Its solid-state electronic design eliminates mechanical moving parts, improving reliability white reducing maintenance requirements. 

The integrated 8-Ohm, 6-Watt loudspeaker with a rectangular-oval diaphragm design (72 × 42.4 mm) ensures efficient sound protection and consistent acoustic performance.

  • Hospital Safety System

Step-by-Step High Intensity Hooter Working Principle?

01

Fire is Detected

Smoke detectors, heat detectors or a manual call point detect a fire or emergency condition and send a signal to the fire alarm control panel.

02

Alarm Panel Activates the Circuit

The fire alarm control panel processes the signal and sends a 24V DC trigger to the connected high intensity hooter.

03

Hooter Receives Power

Once the hooter receives the electrical signal, its internal electronic circuit activates immediately.

04

Alarm Tone is Generated

The device generates a pulsed fire alarm sound pattern (0.30 second ON / 0.30 seconds OFF) designed to stand out from normal background noise.

05

Loudspeaker Produces High-Volume Sound

The built-in 8-ohm, 6-watt loudspeaker convert the signal into a powerful audible alarm with 95-115 dB sound output.

06

Occupants Hear the Alarm and Evacuate

The loud alarm spreads across the area, alerting people to evacuate and take safety action during a fire emergency.
