Operation

The battery in this unit may not be fully charged. After electricity is connected to the unit for at least 24 hours, then normal 

operation of this unit should take effect. 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. 

In accordance with NFPA 101, your emergency lighting system must be tested monthly for a minimum of 30 seconds and 

annually for 90 minutes. Refer to your local codes for any additional requirements that may apply.

Self-Testing Operation (-G2 and -G3/G3PRO models)

This unit automatically performs a 90

second discharge test every month, and a full 90

minute discharge test once a 

year. During routine testing, the self

testing emergency driver simulates an AC power failure causing the unit to 

automatically switch to emergency mode. The unit will monitor the operation of the lighting fixture, internal battery 

voltage, discharging current, and emergency duration. If the emergency system functions properly, then the unit will 

return to normal mode. Should the unit detect any problems, the indicator light will flash continually until the condition 

has been corrected and the unit passes the next test. Please refer to 

Troubleshooting Guide

.  

•  If the unit pass the self

diagnostic test successfully, the message will be cleared automatically after 24hrs. If the unit 

   fails during the test, the indicator light continues flashing until the condition has been corrected or cleared manually.

•  If the condition has not been corrected by the next scheduled test, the unit will once again detect the failure and signal 

   the failure indicator.

•  To cancel a test, press and hold the Multifunction Button ONCE for less than 1 seconds.  

•  To perform 90 seconds manual self

test push and hold Multifunction button for a maximum 3 second. To perform 90 

    minutes manual self

test push and hold multifunction button for a minimum 6 seconds. Once button is released, 

    emergency driver will perform the diagnostic test. After Self

testing is completed, the indicator light will flash per 

    testing results.
