Internal Slave Sounder
The Internal Slave Sounder ensures critical alerts are delivered clearly inside classrooms, corridors, and reception spaces — providing high-intensity audible and visual signaling.
Built for mission-critical infrastructure, this unit delivers high-output audio and a bright internal beacon with site-wide synchronisation. Independent of Wi-Fi and building IT networks, it guarantees performance during network outages or power failures.

Architecture Overview
The Internal Slave Sounder activates instantly when a tactical trigger is pressed. It provides high-intensity signaling to high-traffic zones with no dependence on cabling, Wi-Fi, or building IT infrastructure.
By utilizing synchronized mesh signaling, occupants receive the same instruction simultaneously site-wide. This unit can also be reinforced with optional PC pop-ups and mobile notifications to ensure written clarity alongside the siren.
