Confirm the exact configuration against the current manufacturer specification sheet before approval or purchase.

Engineering reference

## Selecting within the HP Series family.

Size against capacity at the required duration, not the headline wattage. Then choose head count and output. Cold-weather operation is an option rather than standard — confirm it explicitly if the area drops below the standard floor.

HP is the battery unit that HPRL remote heads draw from, and a self-contained unit in its own right. Capacity is published per duration, and the head options are shared with the remote family, so a facility can mix integral and remote positions on one specification.

Controlled document

## HP Series specification sheet

The manufacturer's specification sheet remains the controlling project document.

Common questions

## Useful answers before the next step.

These answers clarify the selection process without replacing project-specific documentation.

**How is this related to the HPRL remote fixtures?**

HP units power HPRL remote heads over low-voltage wiring, and both use the same L6, L10 and L15 head options. A single specification can mix integral and remote positions.

**What durations are documented?**

Capacity is published at 1.5, 2, 3 and 4 hours. Size against the figure at the duration the occupancy requires rather than the nominal wattage.

**Is cold-weather operation available?**

The standard range is 32 to 122 °F with an optional cold-weather build extending to −40 °F. Confirm the option explicitly if the area drops below freezing.
