Emergency Driver Power Input Wiring
D4 Emergency Drivers are available for systems requiring emergency lighting control.
Note:
D4 Emergency Drivers require two branch circuit power input connections, normal sense and
maintained (emergency).
Maintained (emergency) provides constant power to the D4 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 D4 Driver will force all output channels on the D4 Driver to full (100%). Any
control of the connected output channels will be unavailable until normal power has been
restored.
Emergency System One-Cell Installation
The installation must conform to local and national codes.
