Electric sirens are critical alarm devices that alert occupants to fire emergencies through loud, attention-grabbing sound signals. These devices activate automatically when connected to fire detection systems, ensuring rapid notification even in noisy environments or when visual alarms alone may be insufficient. Key functions include: - Producing high-decibel sound output (typically 85–120 dB) to penetrate walls and background noise - Operating on standard electrical power with battery backup options for reliability during power failures - Integrating seamlessly with fire alarm control panels and detection networks - Meeting Indian fire safety standards and building codes for commercial and residential installations Electric sirens complement visual warning systems and are essential in multi-story buildings, industrial facilities, hospitals, and large commercial spaces where immediate, widespread notification is critical. They reduce evacuation time and improve overall fire safety response by ensuring no occupant misses the alarm signal.
