EMIU 125/250/400W Mini Inverter
SYSTEM OPERATION
• The diagnostic/charger is a self-contained, fully automatic microcontroller-based system.
• Once the installation is complete, it is not necessary to have the AC power energized. Only the battery needs to be connected.
The unit goes directly into lockout mode and waits for AC power to be restored.
1. ALARM SILENCE / MANUAL TEST / SYSTEM INITIALIZATION
• Alarms are silenced by pushing the “TEST” switch less than one half second. Alarm indication can only be silenced after correcting the
fault or by re-initializing the system.
• Manual forced tests are initiated by pushing and holding the “TEST” switch more than one second. The 1-minute test will start.
• System initialization is done by holding the “TEST” switch for at least 6 seconds.
2. DIAGNOSTIC AND NEXUS®(OPTION)
If the audible alarm has been activated, any fault condition will produce an audible warning that
consists of an intermittent beep: one second on, one second off.
Refer to figure 3 for two lists of possible conditions.
a. BATTERY DISCONNECT / INVERTER FAILURE
The status indicator displays a steady red LED if the battery circuit is open or
shorted, or if there is an Inverter failure.
b. BATTERY FAILURE
The status indicator displays 1 red blink and a pause of 5 seconds if an incorrect battery
is installed (e.g. 12V battery on a 6V system), or if the battery has failed a timed or forced
test (reached LVD level before the end of the test).
c. CHARGER MONITORING
The status indicator displays 2 red blinks and a pause of 4 seconds if the charging cur-
rent does not fall within limits corresponding to the charger command state.
d. LIGHTING LOAD CAPTURE SEQUENCE
The capture sequence is initiated only by a reset of the system. This is done by holding the “TEST” switch for at least 6 seconds. The
reset also initializes the main counter. This renewal takes place to compensate for system variations when the unit ages. Renewal is not
allowed if there is a lighting load failure alarm. This is not applicable for units with no auto-test option.
e. SERVER FAILURE
The Nexus server (controller or PC) is no longer communicating with the RF unit’s modem. To solve this issue, you need to verify if the
Nexus server is up and running. If it is up and running, check to see if other surrounding emergency lighting units are not powered. If they
are powered off, they will prevent the unit in question to communicate with the modem. Otherwise simply reset the modem.
f. BLINK MODE
A “Blink mode” signal was sent from the Nexus server (controller or PC) to the emergency lighting unit. To stop the “Blink mode”, you
need to access the Nexus server and execute a stop blink mode operation.
g. NOT COMMISSIONED
The unit was not commissioned and therefore not registered in the Nexus server. Once the unit is commissioned, the auto-test will be dis-
abled and the LED will show a steady green for 10 seconds and steady orange for 1 second.
To cancel a fault condition, after applying all corrective actions, simply reset the unit.
*Refer to Nexus®installation addendum for more details.
3. AUTOMATIC UNIT TEST (30-DAY TEST)
Every 30 days, while in charging mode, the sequence generator will generate a command to energize the transfer on the emergency
lighting circuit for a variable test period depending on the yearly sequence.
• If the battery fails to complete the discharge test, the charger will display a battery failure and the test will abort.
• The 30-day automatic test sequence is reset every time the lighting load is turned on, including the manual test.
FEATURES AND OPTIONS
IMPORTANT: Reset the system whenever you add or change the lighting load. To reset the system, press the
test switch for 6 seconds.

EMIU 125/250/400W Mini Inverter
4. LIGHTING LOAD TESTING
The test is fully automatic. To maintain accurate data, these 2 conditions must be met prior to acquiring values from an all-good lighting load:
• The battery has to be at or near full power. The program will delay data capture for a minimum of 48 hours following any
discharge or reset.
• The charger will also wait to be in hysteresis mode (charger cycling on/off).
5. AUDIBLE ALARM (BUZZER)
This option can be activated or de-activated in the field. Refer to Figure 4.
To select the audible alarm option:
a. Remove all power sources to the board (AC and battery).
b. With long-nose pliers, pull on the shunt (little black box) until it is free from the pins.
c. Put the shunt back in place according to the option selection.
d. Reconnect AC power and the battery.
6. SERVICE ALARM OPTION (INDICATOR)
If installed, insert each wire of the Building Alarm Panel into separate terminals of the terminal
block marked “SERVICE ALARM”.
Alarm Panel shall provide a 24V signal. The charger board will indicate a fault by closing a
contact. Polarity is not specified.
7. LIGHTING CONTROL OVERRIDE
This feature is used with lighting loads equipped with low voltage dimming control. The dimming
function must be disabled during a power failure in order for the load to provide a 100% level of lighting.
The circuit consists of a single-pole dry-contact relay that is normally closed in stand-by operation. In emergency mode (power failure) the relay
contacts open and disconnect the dimming signal from the lighting load, allowing the load to operate at 100% light level.
INSTALLATION:
1. Locate the Lighting Control signal cable pair.
2. Cut, strip and extend one wire only, of the Lighting Control signal cable.
3. Connect to the terminal block marked "LIGHTING CONTROL OVERRIDE" as shown in the wiring diagram below.
8. UNITS WITH NO AUTO-TEST
This equipment is not self-testing in conformance with the Life Safety Code, ANSI/NFPA 101.
IMPORTANT: Must install a minimum lamp load equvivalent to 10% of the rated capacity of the unit.
Example: 12.5W/VA for a 125W inverter unit.
IMPORTANT: Only one control signal can be handled by one LCO module. Multi control signals require one LCO per control
signal. Consult customer service if there is more than one Lighting Control signal to be overridden.
