Overview

The FireProtect (VAD) Jeweller is a wireless visual alarm device designed for high-intensity emergency notification in EN54 compliant fire systems. Featuring a powerful LED frame, it delivers a clear red strobe signal every two seconds to alert occupants in noisy environments or where hearing protection is used.

Advanced Enclosure Design

The VAD Jeweller features innovative hardware housed in a sleek, compact enclosure that blends seamlessly into any interior. 

Designed for maximum flexibility, it supports both wall and ceiling installation using a rotatable SmartBracket for optimal positioning. 

The hardware is built for long term maintenance ease, featuring a tool-free battery compartment for quick replacements and an optional bracket lock to prevent unauthorised removal or tampering.

Efficient Visual Indication

The VAD Jeweller utilises a high intensity perimeter LED frame to provide unmistakable visual notification. 

In the event of an alarm, the frame emits a powerful red strobe following a strictly compliant temporal pattern to ensure maximum visibility. 

Engineered for versatility, the device supports both wall and ceiling mounting, eliminating traditional installation constraints. This flexibility allows engineers to strategically position the VAD for optimal coverage, effectively securing the premises with a more efficient device footprint.
