          3.   Transfer: Within milliseconds of loss of utility power on
               a monitored circuit, and in no case more than the 10
               seconds UL 924 allows.
          4.   Recharge: To full capacity within 24 hours of a discharge
               per UL 924. An optional fast charger recharges from full
               discharge in under 12 hours.
          5.   Branch wiring: Two to four conductors, #18 to #8 AWG;
               loads may be Class 2; 1-hour rated MC cable where NEC
               Article 700 requires it. Conductor size and length for
               each branch per the manufacturer's voltage drop
               calculation for the connected load, 15 percent maximum
               drop at the last device.

          1.   Enclosure: NEMA Type 1, UL 50 steel, surface mount,
               optional recess mount.
          2.   Input: 277 VAC, a factory input option (120 VAC is
               standard); optional second input from a generator.
          3.   Batteries: Two commercially available 12 V sealed
               lead-acid batteries, removable in minutes without ladders
               or lifts.
          4.   Charger: Computer controlled, float voltage maintained
               continuously.
          5.   Optional output for switched night or security lighting.

     E.   Self-Test: Automatic self-test and self-diagnostic operation
          as NFPA 101 requires of computer-based emergency lighting
          equipment: a monthly 30-second functional test and an annual
          90-minute discharge test, each result logged. Test reports
          transmitted by email to up to six addresses.

     F.   Monitoring: Each cabinet supplied with an individual IP
          address and Sage Live, the manufacturer's monitoring and
          reporting system, allowing remote monitoring of every test
          function including load variation on each emergency branch
          circuit. Data to the operator by Ethernet local network, a
          cloud-based server, or other means the Owner specifies. Faults
          reported by email as they occur. An installed test report
          printer is available as an option.

2.3  SAGE RELAY, EMERGENCY LIGHTING CONTROL

     A.   Basis-of-Design Product: Sage Relay, RLY-1 through RLY-6, for
          the general lighting luminaires designated for emergency
          operation on the Drawings, selected by the manufacturer to
          each luminaire's LED driver by load, voltage and form factor,
          from the luminaire schedule.

     B.   Operation: On loss of normal power to the luminaire, the Relay
          drives the luminaire's LED array from the central battery over
          the low voltage DC circuit, independent of the luminaire's own
          driver, for a minimum of 90 minutes. Normal lighting operation
          and the lighting controls are not affected. No UL 924 bypass
          relay or automatic load control relay is required for the
          luminaires so equipped; the Relay is the listed emergency
          lighting control.

     C.   Mounting: In the luminaire's driver compartment alongside the
          LED driver, or in a junction box within 30 feet of the
          luminaire.

     D.   Listings: UL 924.

2.4  GENERAL LIGHTING LUMINAIRES FITTED WITH THE SAGE RELAY

     A.   The general lighting luminaires scheduled under Section 26 51
          00 and designated for emergency operation on the Drawings
          shall be fitted with a Sage Relay. The luminaire, its LED
          driver and its controls are retained as scheduled.

     B.   The Relay is installed in the luminaire's driver compartment
          or in a junction box within 30 feet of the luminaire, by the
          Contractor per the manufacturer's installation guide, or by
          the luminaire manufacturer where the luminaire schedule so
          specifies.

2.5  CENTRAL BATTERY EMERGENCY LUMINAIRES

     A.   Basis-of-Design Products: Sage CB Fixtures, Signature Series,
          as scheduled on the Drawings: Orion for high mounting heights,
          Aspen for exterior and wet locations, Phoenix, Ignite,
          Obsidian, Onyx, Aurora and Radiant.

     B.   Operation: Remote configuration, 24 VDC from the central
          battery, with emergency operation for a minimum of 90 minutes
          in compliance with UL 924 and NFPA 101. Where the Drawings
          indicate, the luminaire may be specified to operate
          continuously for security or night lighting.

     C.   Photometric Data: IES LM-63 files as published by the
          manufacturer for each luminaire and lens.

2.6  EXIT SIGNS

     A.   Basis-of-Design Product: Sage Rowan compact thermoplastic LED
          exit sign, remote configuration on 24 VDC from the central
          battery system. Other Signature Series exit signs as scheduled
