The Fire Alarm Input allows power transfer to the emergency power source (if emergency power is present)
when triggered by an external system.
Note:
This transfer is activated even when normal power is still present.
The 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:
The fire alarm input functions with up to 1,000ft (300m) of 18AWG wire connected between the
input and the switch. Fire Alarm Inputs of up to 10 ELCD 1008 units can be wired together using a
single normally open or normally closed contact.
See Fire Alarm Input on page 7 for details.
The 0– 10V Auxiliary Output provides an additional single pole relay that opens when the unit is in the
emergency state. This allows connection of 0– 10V or DALI ballasts that need the removal of the
control signal in order to illuminate at full in an emergency state.
Using the mounting holes in the bottom of the
enclosure, secure the ELCD 1008 enclosure to
a flat surface using four 1/4-20 mounting bolts or
screws (provided by others).
Four knockouts are provided on the side of the
enclosure. Install conduit fittings (provided by
others).
The ECLD1008 enclosure can be
r o t a t e d 9 0 ° , t o c h a n g e t h e
orientation as needed for the
installation.
The front cover has a legend
printed on both sides to insure
correct indication of status LEDs
and Test Switch.
