The Sage Line

Sage is designed as a single coherent emergency lighting system — not a collection of separate products.

Central battery cabinets power Sage Relay modules, CB Fixtures, Luminaires, and Exit-and-Emergency units across the entire building.

3 Products

Sage Central Battery

One system. Entire building.

Patent-protected central battery cabinets (Keystone, Volta) plus Olympus local-branch-circuit monitoring. Power an entire building's emergency lighting from one low-voltage DC source.

6 Products

Sage Relay

Emergency relay modules, engineered.

SR-series relay modules that convert standard LED luminaires to central-battery-powered emergency operation. Sized by host-fixture wattage class.

12 Products

Sage CB Fixtures

Architectural emergency lighting.

Low-profile architectural luminaires designed to run directly off Sage central battery. Recessed, surface, wall, and high-output variants for premium commercial spaces.

3 Products

Luminaires

General lighting, emergency ready.

General lighting fixtures with an optional factory-installed Sage Relay. One fixture, two roles — normal lighting and central battery emergency.

7 Products

Exit and Emergency

Exit signage and emergency units.

Exit signs, combination exit + emergency units, and emergency battery units with lamp heads. Edge-lit LED, thermoplastic, and architectural options. Central battery compatible across the line.
