CAUTION: Before installing, make certain the A.C. power is off and the I-880 unit connector is disconnected.
1. LAMPS OPERATED
The I-880 can be used with most 2 ′–8′ lamps. Refer to the chart below for the type of lamp(s) operated and the number
of lamps to be operated in emergency mode.
*The 6 ″ violet leads provide the lamp selection option. The unit is shipped from the factory with the leads disconnected
and capped. When used with particular lamp types, violet leads should be connected to one another. Refer to chart for
lamp selection options.
2. MOUNTING THE I-880
Remove the ballast channel cover. Mount the I-880 in the ballast channel at least 1 /
2
″ away from the A.C. ballast(s).
The I-880 may also be mounted on top of the fixture. The optional top mounting kit (Catalog No. TMK-80) may be
ordered separately from Customer Service.
When battery packs are remote mounted, contact Customer Service for the maximum allowable distance between
battery pack and lamp.
3. WIRING
