Fire Alarm Input
The Fire Alarm Input allows power transfer to the emergency power source (if emergency power is
present) when triggered by an external system.
Note:
The dry contact input can be configured for normally open or normally closed operation using switch
settings on the control board. Normally open and normally closed refer to the normal operational
state of the external circuit, not to the de-energized state of the external relay.
When the contact input is triggered, the unit will transfer to the emergency power source.
•
When the contact input trigger is removed, the unit will transfer back to the normal power
•
source, if present, or will remain on emergency power until normal power is restored.
Note:
connected between the input and the switch. Fire Alarm Inputs of up to ten SC1008 units
can be wired together using a single normally open or normally closed contact. See
Alarm Input on page 8
0–10 V Auxiliary Output
The 0–10 V Auxiliary Output provides an additional single pole relay that opens when the unit is in
the emergency state. This allows connection of 0–10 V or DALI ballasts that need the removal of the
control signal in order to illuminate at full in an emergency state.
