Engineering reference ## Choosing the right Survive-All SVH configuration. Start with the required duration for the occupancy, then read the capacity at that duration rather than the headline wattage. Then confirm the hazardous groups and the lamp head option. Ambient matters — the documented range is narrower than the non-classified families. SVH is the classified-area member of the Survive-All range. Its capacity table is published per duration rather than as a single figure, which is what a code calculation actually needs: the wattage a unit sustains for 1.5 hours differs from what it sustains for three. Manufacturer document ## Survive-All SVH specification sheet The manufacturer's specification sheet remains the controlling project document. [View specification sheet](https://maeslighting.com/assets/docs/survive-all-svh.pdf) Common questions ## Frequently asked questions These answers clarify the selection process without replacing project-specific documentation. **Why is capacity listed at several durations?** Because a battery sustains less load the longer it runs. The table publishes capacity at 1.5, 2, 3, 4 and 8 hours, so the correct figure to size against is the one at the duration your occupancy requires. **What hazardous approvals are documented?** Class I Division 2 Groups A, B, C and D with UL 924 listing. Confirm the groups and temperature code against the specific catalog number. **What operating range applies?** 50 to 104 °F. That is narrower than the SV and HP families, which offer cold-weather options — confirm the ambient before selecting. --- Maes Lighting — nationwide supplier of certified explosion proof, industrial, high-temperature, food-processing, vapor-tight, high-bay, flood, area, and emergency LED lighting.
