INSTALLATION INSTRUCTIONS
CAUTION: Before installing, make certain the A.C. power is off.
NOTE:
The battery is shipped in separate packaging for ease of handling. Store the battery in a cool, dry and safe
location until ready for installation. The battery may be kept in storage for up to 3 months without recharging.
CAUTION:
This is a dual input and output voltage unit. It can be connected to either a 120 or 277 volt supply.
The input and output voltages must match
.
Mounting the IIS 550 I
1) Remove the front cover of the
IIS 550 I
by removing the two (2) screws located at the top of cover.
2) Knock out the keyhole slots at the rear of the unit and use for mounting the
IIS 550 I
securely to the wall. There is an additional
round hole for a #10 screw in the cabinet. Code requires that an additional screw be used through this hole to prevent the unit
from being inadvertently lifted up off the keyhole slots.
Do not drill any holes in this unit
.
3)
Extend an unswitched AC supply, normally-on lamp supply (if used), and the load wires to the unit. 1/2
″
conduit knockouts
are provided in the back and sides of the unit for wires to pass through. NOTE: Input and output wires must be run in separate
conduits.
CAUTION
: Do not drill holes into the cabinet; drill filings may damage the unit and keep it from operating.
CAUTION: The IIS 550 I must be mounted securely. Do not rely on the junction box for supporting the weight of the
unit. Mount the IIS 550 I securely to the wall using the keyhole slots provided.
ALWAYS CONSULT LOCAL CODES FOR STRUCTURAL REQUIREMENTS WHEN MOUNTING THE UNIT.

- ALWAYS ON FIXTURES
Fixtures are used for both normal and
emergency power conditions. During
a loss of normal AC power, the IIS
automatically senses the drop in line
voltage, and powers the fixtures with its
internal battery.
- SWITCHED FIXTURES
Fixtures are used for both normal and
emergency power conditions, and are
controlled by a local switching device.
During a loss of normal AC power, the
IIS automatically senses the drop in line
voltage, and powers the fixtures with
its internal battery, regardless of the
position of the switching device.
- NORMALLY OFF FIXTURES
Fixtures on the emergency circuit are
used in emergency mode only, and
are not energized during normal power
conditions (Note: Normal AC Input leads
are not connected).
