Directo S M 3H AT is a compact evacuation luminaire from Intelight with a white PC housing and a PMMA light guide plate that spreads the LED light evenly across the sign face, giving up to 25 m sign visibility. It runs in maintained (M) mode with a built–in automatic self–test (AT), so faults are detected without manual testing.

The unit is powered from 230 VAC, draws only 3 W and gives 3 hours of autonomy from its 2xAA 2.4V 900 mAh NiCd battery pack when mains power is lost. The LED light source is rated for 50,000 hours and the colour rendering index is Ra≥80. Protection rating is IP20, for indoor use between 10°C and 40°C.

Directo S can be mounted on the surface, on a wall, recessed into the ceiling, suspended, or fitted with a flag bracket for perpendicular mounting in corridors, using the same housing across all variants.
