FAQs
Install the luminaire in a ceiling surface mounting location using the plug-in connection. Use a 230 V AC supply and a 2.5 mm2 conductor. The unit supports standby switching for simple integration with existing circuits, and its compact 138 mm diameter housing fits standard ceiling gaps, reducing installation time and labor costs.
Yes. The unit is rated IP44 and class II protection, making it suitable for indoor environments with dust and moisture exposure typical of corridors, open areas, and industrial facilities. It is not intended for outdoor use.
The RT2SSO150SA3H provides 3 hours of autonomous operation with a built-in 3.2 V lithium-ion battery. It uses a non-exchangeable LED light source delivering about 150 lm, color temperature around 5700 K, and a 4-LED configuration for reliable, high-visibility emergency lighting.
The luminaire carries CE certification and ENEC-related references for stringent safety compliance, plus an IP44 rating and CE/ENEC documentation in the product downloads. Glow-wire testing to 850 °C further supports its safety credentials in critical environments.
With a long rated life of up to 60600 hours and a low max system power of 0.2 W, the unit minimizes replacement frequency and energy consumption. Quick plug-in installation reduces commissioning time, while durable materials and safety certifications lower maintenance and regulatory risk over the asset’s lifetime.
