Gent S3-S-VAD-HPR-W High-Power Sounder with Red VAD – White Body

The Gent S3-S-VAD-HPR-W is a premium loop-powered alarm sounder with an integrated high-power EN54-23-certified Visual Alarm Device (VAD), featuring a white body with a striking red lens. Designed for use with Gent Vigilon fire alarm control panels, this unit provides both audible and visual alerts, ensuring fast and effective evacuation in all environments, including those with high ambient noise or complex layouts.

Part of the innovative S-Cubed range, the S3-S-VAD-HPR-W White Body supports synchronised voice, tone, and light outputs across the system, enabling clear and consistent alarm communication throughout the building. Its exceptionally low current draw means more devices can be connected per loop compared to other manufacturers, reducing wiring costs and maximising loop capacity.

The device offers four pre-recorded voice phrases, a standard bell tone, and adjustable output levels, allowing installers to configure it for distinct alert and general evacuation signals. Flexible cause-and-effect programming through Gent control panels ensures tailored operation for site-specific safety requirements.

Key Features & Benefits

• Combined high-power sounder and red-lens VAD in a single loop-powered device.
• Supports up to 200 voice sounders, 100 VADs, and 70 combined sounder/VADs per loop.
• EN54-23-certified VAD with adjustable light coverage matched to sounder output.
• Four built-in voice phrases plus bell tone for customised evacuation messaging.
• Configurable voice and tone modes within a single unit.
• Adjustable sounder volume via commissioning tools, fire panel, or HandiLink infrared remote.
• Continuous background monitoring of sounder and VAD circuits for reliability.
• Low power consumption optimises loop capacity and reduces installation costs.

Compliance & Standards

• EN54-3 and EN54-23 certified.
• CE and UKCA marked.
