Listen to Lockdown Alarm Sounds & Alerts

Overview

The Internal Slave Sounder activates the moment your Master Call Point or remote keyfob is pressed.
It provides a clear siren and bright beacon indoors, ensuring your lockdown message reaches:

• Classrooms and internal teaching spaces
• Staff rooms and offices
• Corridors and shared internal areas
• Reception and visitor zones

No Wi-Fi, building cabling, 4G or network dependency.

Key Features

• Loud internal lockdown alarm and visual beacon.
• Instant activation when Master Call Point or keyfob is pressed.
• Secure RF signalling – fully independent of Wi-Fi or building IT infrastructure.
• Battery powered for continuous operation during outages.
• Synchronises with all external and internal lockdown sounders.
• Supports Martyn’s Law / Protect Duty risk planning.
• Low-disruption install – no new cables through walls or ceilings.

How the Internal Slave Sounder Works

1. Lockdown is activated by the Master Call Point or remote keyfob.
2. The secure RF network sends the activation signal site-wide.
3. All Slave Sounders activate together indoors.
4. Siren + beacon signal staff and pupils to follow lockdown procedures.
5. System reset via Master Call Point key.
