Emergency Driver Power Input Wiring
47
ArcLamp Drivers are available in UL924 listed variants including:
•
ArcLamp Driver 150: 115 W (convection cooled) supplies power for up to 25 individual
4.4 W ArcLamps
•
ArcLamp Driver 350 (wall-mount or rack-mount): 264 W (single fan) supplies power for up
to 60 individual 4.4 W ArcLamps
•
ArcLamp Driver 700 (wall-mount or rack-mount): 528 W (dual fans) supplies power for up
to 120 individual 4.4 W ArcLamps
ArcLamp Emergency Drivers require two branch circuit power input connections, normal sense
and maintained (emergency).
•
Maintained (emergency) provides constant power to the ArcLamp Driver regardless of the
state, enforcing the ability to maintain a lights on condition when needed. The power
source must be connected to an emergency branch circuit with an upstream UL1008
automatic transfer switch.
•
Normal sense detects when normal power is present. In the event of a normal power
failure, the ArcLamp Driver will force all output channels on the ArcLamp Driver to full
(100%). Any control of the connected output channels will be unavailable until normal
power has been restored.
