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).

Note:
The system supports connection of up to 10 ELCD 1008 units connected in
parallel to the fire alarm device.
The ELCD 1008 features a single pole auxiliary relay that provides switching for installations utilizing 0–10V or
Digital Addressable Lighting Interface (DALI) controls. In the event of an emergency, the relay opens the control
circuit, sending any connected loads to their full intensity output.
0-10V Auxiliary Output
Note:
All low–voltage Class 2 wiring must be separated from all Class 1 wiring. Follow local codes
and installation restrictions.
Isolite recommends limiting the distance run for the 0–10V control wiring from the
controller to the last ballast (driver) to 300ft, based on 18 AWG wire.
1. Run a +10V wire, typically purple, between the 0–10V controller and the 0–10V terminal 10 in the ELCD 1008
and secure the terminal onto the wire.
2. Run a +10V wire, typically purple, between 0–10V ballast and the 0–10V terminal 9 in the ELCD 1008 and
secure the terminal onto the wire.
3. Run a common wire, typically gray, between the 0–10V controller and the 0–10V ballast.
Fire Alarm Input
The ELCD 1008 features a single dry–contact input that can
be used to force the transfer from normal to emergency
state, even if both normal and emergency power are
present. The contact may be configured for either normally
closed (NC) or normally open (NO) operation by setting
switch 1 and 2 on the ELCD1008 control board.
1. Run a positive control wire between the fire alarm device
and the FIRE ALARM 11 “+” terminal in the ELCD 1008
and secure the terminal onto the wire.
2. Run a negative (common) control wire between the fire
alarm device and the FIRE ALARM terminal 12 “-”and
secure the terminal onto the wire.
