Addressable Notification
Where versatility meets efficiency and safety
How It Works
Each notification device (horn, strobe, or speaker) is assigned a unique digital address.
When a fire or emergency is detected, the control panel sends a specific activation signal only to the relevant devices.
Depending on programming, the system can:
Sound alarms in affected areas first, then extend if needed.
Flash strobes for visual alerts in noisy environments.
Broadcast voice instructions to guide safe evacuation.
Devices continuously communicate with the panel, allowing real-time status monitoring and fault reporting.
Integration with building automation ensures synchronized actions such as unlocking exit doors, activating emergency lights, or controlling ventilation.
Addressable notification systems are intelligent fire alarm output devices designed to alert building occupants during emergencies with clear, reliable, and targeted signals. Unlike conventional systems where alarms activate broadly, addressable notification devices are digitally identified and controlled by the fire alarm panel. This enables precise activation by location, floor, or zone, reducing confusion and ensuring faster, safer evacuations. Harsha Engineers India integrates these systems into its automation solutions to deliver seamless, coordinated safety management for industrial, commercial, and institutional facilities.
