Agni Veiga Series Intelligent Addressable Sounder Strobe Base

The IND-SV2MB or IND-S2MB Sounder Strobe Base is a low-profile, intelligent addressable audio-visual base designed for use with Agni Veiga Series detectors. It delivers reliable audible and visual alerts with low current consumption, making it ideal for indoor fire alarm applications. 

Description

The IND-SV2MB or IND-S2MB  Sounder Strobe Base is an aesthetically pleasing, compact audio-visual base sounder engineered for intelligent fire detection systems. Agni Veiga Series intelligent detectors base, it combines a powerful audible alarm with a white visual flash in a single ceiling-mounted unit. 

This sounder strobe base offers surface mount slim profile acoustic output and EN54-23 compliant visual performance, while maintaining extremely low current consumption. When connected with an associated intelligent detector, the unit can be fully controlled through cause and effect programming from a compatible control panel using the Agni Digital protocol. 

Integrated DIP switches allow independent adjustment of both sounder volume and tone settings, providing flexibility for different site requirements. The unit can function as a detector base or operate independently with a cover plate, ensuring adaptability across various installations.
Loop Powered Sounder Strobe Base reduces cabling complexity and enables faster, cleaner installation. It is particularly suitable for noisy environments or areas with low visibility, where both audible and visual alerts are essential. 

Job to be Done

Activate a clear visual Flash indicator during alarm conditions, Easy installation support all agni veiga series detectors reduce cable wirings

How it Works

How does the Agni Veiga Sounder Strobe Base Work?

The Agni Veiga Sounder Strobe Base works by receiving commands from an addressable fire alarm control panel and producing audible and visual alerts during a fire event. 

It is powered directly through the fire alarm loop and communicates using the Agni digital protocol.

How does the Agni Veiga Sounder Strobe Base Operate?

1. Standby Mode

The Sounder Strobe standby while continuously communicating with the addressable fire alarm control panel through the Agni digital protocol. Power is supplied directly from the fire alarm loop.

2. Fire Event Detection

An associated intelligent detector (smoke or heat) senses a fire condition and sends a signal to the control panel.

3. Control Panel Processing

The fire alarm control panel verify the alarm condition and applies cause-and-effect programming to determine which sounder strobe cards must activate.

4. Activation Command Sent

The control panel sends an activation command to the Sounder Strobe Card via the addressable loop.

5. Audible Alarm Activation

The Sounder Strobe Card activates the sounder, producing an alarm within the 440-2900 Hz frequency range, with sound output up to 92.6 dBA (tones 32).

6. Visual Indicator Activation

Simultaneously, the integrated visual indicator turns ON, providing a clear visual warning for occupants, especially in low-visibility or noisy environments.

Product in One Line 

When a fire emergency occurs, the Sounder Strobe Base must instantly alert occupants by delivering a loud audible alarm and a clear visual warning, using minimal wiring and reliable addressable control.
