SAVE THESE INSTRUCTIONS

THIS PRODUCT CONTAINS A RECHARGEABLE NICKEL-CADMIUM BATTERY.

THE BATTERY MUST BE RECYCLED OR DISPOSED OF PROPERLY.

1. Do not join converter connector until installation is complete and AC Power is supplied to the emergency driver.

2. This product is for use with an emergency LED lighting load and supplies nominal 10.0 W of power with a

maximum voltage of 50 VDC in emergency mode for a minimum of 90 minutes.

3. Make sure all connections are in accordance with the National Electrical Code or Canadian Electrical Code and

any local regulations.

4. To reduce the risk of electric shock, disconnect both normal and emergency power supplies and converter

connector of the emergency driver before servicing.

5. This emergency driver is suitable for factory installation only.

6. This product is suitable for use in damp locations where the ambient temperature is 0ºC minimum, +55ºC

maximum. Product is also suitable for installation in sealed and gasketed ﬁ xtures. Product is not suitable

for heated air outlets and wet or hazardous locations. Maximum allowable case temp is 65ºC.

7. An unswitched AC power source is required (120-277 VAC, 50/60 Hz).

8. Do not install near gas or electric heaters.

9. Do not attempt to service the battery. A sealed, no-maintenance battery is used that is not ﬁeld replaceable.

Contact the manufacturer for information on service.

10. The use of accessory equipment not recommended by the manufacturer,may cause an unsafe condition.

11. Do not use this product for other than intended use.

12. Servicing should be performed by qualiﬁed service personnel.

13. Equipment should be mounted in locations and at heights where it will not be subjected to tampering by

unauthorized personnel.

14. For Canadian application,the output terminals should be in compliance with the accessibility requirement of

the Canadian Electric Code.

15. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1)

this device may not cause harmful interference, and (2) this device must accept any interference that may cause

undesired operation.

16. This product must be grounded. See the wiring diagrams for details.

INSTALLATION

NOTE: Make sure the necessary branch circuit wiring is available. An unswitched source of power is

required. The emergency driver must be fed from the same branch circuit as the AC driver.

CAUTION: DO NOT JOIN CONVERTER CONNECTOR UNTIL INSTALLATION IS COMPLETE AND AC POWER IS

SUPPLIED TO THE EMERGENCY DRIVER.

>Mounting Height: This product meets or exceeds the NFPA minimum light requirements with all loads, down to the

smallest rated lamp load, at heights up to 7.17ft (2.2m). Many factors inﬂuence emergency illumination levels, such as

the lamp load selected, luminare design, and environmental factors therefore end use veriﬁcation is necessary. For ﬁeld

installations, when the attached luminaire is mounted at heights greater than 7.17ft (2.2m), the level of illumination

must be measured in the end application to ensure the requirements of NFPA 101 and local codes are satisﬁed.

>Remote Mounting: The emergency LED driver may be remote mounted from the luminaire. If used in conjunction with

an AC driver the allowed distance is up to half the distance the AC driver manufacturer recommends remote mounting

the AC driver from the LED load. If used without an AC driver, and remote mounting more than 5 feet from the luminaire,

please consult the factory to determine the necessary wire gauge. CAUTION: Remote mounting can result in reduced

power output.

EMERGENCY DRIVER AND AC DRIVER MUST BE FED FROM THE SAME BRANCH CIRCUIT

NOTE: For short-term testing of the emergency function, the battery must be charged for at least one hour. The

emergency driver must be charged for at least 24 hours before conducting a long-term test.

During normal operation AC power is applied, the charging indicator light is illuminated, indicating that the battery is

being charged. When power fails, the emergency LED driver automatically switches to emergency power (internal battery),

operating the LED load for a minimum of 90 minutes. When AC power is restored, the emergency driver returns to the

charging mode.

Although no routine maintenance is required to keep the emergency driver functional, it should be checked periodically to

ensure that it is working. The following schedule is recommended:

1. Visually inspect the charging indicator light monthly. It should be illuminated. If the charging indicator is

flashing. Contact tech support.

2. Test the emergency operation of the fixture at 30-day intervals for a minimum of 30 seconds. The LED load

should operate at reduced illumination.

3. Conduct a 90-minute discharge test once a year. The LED load should operate at reduced illumination for at

least 90 minutes.
