The Sentinel system
A complete lockdown system, designed to be invisible until it isn't.
Sentinel combines wired and wireless activation, a central Hub, and a full audio-visual response network into one resilient, easy-to-operate system.
How a lockdown flows through Sentinel
Triggers feed the Hub · the Hub orchestrates every response
Sentinel Hub
The brain of the system. Every trigger feeds into the Hub, which instantly coordinates the entire response, voice, sirens, strobes, doors, screens and outside help, in the right order, every time.
System components
Each component is engineered for reliability in the moments where reliability matters most.
Wired Call Points
Tamper-resistant emergency buttons mounted in classrooms, corridors and reception areas.
Wireless Panic Buttons
Pocket-sized fobs paired to the Hub for instant activation from anywhere on site.
Sentinel App
Secure iOS application for authorised personnel to start or stop a lockdown remotely.
Sentinel Hub
The brain of the system. Coordinates every input and orchestrates every response.
Voice Alerts & Sirens
Clear, pre-recorded verbal announcements through the existing or supplied speaker network.
Visual Strobes
High-visibility strobe beacons for noisy or hearing-impaired environments.
Door Control
Integrates with access control systems to lock or release doors on activation.
ARC Integration
Automatic notification to your Alarm Receiving Centre and on-site security.
Activation
Three trusted ways to trigger.
We don't believe in single points of failure. Every Sentinel installation includes multiple activation routes, wired, wireless and mobile, so the alert always gets through.
- Wall-mounted wired call points, zoned per floor or department
- Wireless pocket fobs with rolling encryption
- Secure iOS app with biometric authentication
