The Schneider Electric MTN6304-0019 is a KNX high-bay presence detector (flush-mount FM variant) for indoor ceilings from 2.5 m to 14 m height. Passive infrared sensing with precision shrouds covers warehouse aisles, logistics halls, and large retail spaces where standard detectors lose range.

Creep zone protection monitors the area directly beneath the unit. Surface and flush variants share the same detection platform as MTN6354-0019 (surface high-bay). Bus-powered on KNX SELV 21–30 V; parameterise via ETS 5.x or higher.

Key Features — High-Bay Presence Detector

• Mounting height: 2.5–14 m (typical high-bay applications).
• Detection: 360° coverage, 180° aperture; up to ~18 m lateral range (temperature-stabilised).
• Switching zones: Up to 1416 zones (ETS).
• Twilight: 2–1000 lux teach-in; dual-light switching/dimming.
• Protection: IP54 surface / IP20 flush; −20 °C to +50 °C.

Applications and KNX Integration

• Warehouses and factories: Aisle lighting on occupancy; pair with MTN6700-0304 (20 A) for heavy circuits.
• Corridors in same building: MTN6355-0019 for 2.5–5 m corridor geometry.
• Standard office ceilings: MTN6300-0019 or MTN630819 ARGUS.
• Alternative high-bay: EAE HD100, ITR415-0001.
• Energy monitoring: MTN6600-0603 on fed lighting circuits.

Choosing High-Bay vs Corridor Detectors

Specify MTN6304-0019 when mounting height exceeds ~5 m. For long narrow corridors at standard ceiling height, use MTN6355-0019 instead.
