Manual Testing
The equipment comes standard with a one-
button infrared remote control.
Before starting manual testing remove plastic
tab from battery compartment on remote
control.
To initiate a test: orient the remote control
towards the pilot light of the unit and press the
TEST button.
13. Test function (power on, stand-by): press the TEST button, the unit
will start a one-minute test. Pressing the button again will abort the
test in progress.
14. Load disconnect: this option can be used during a power failure to
save battery power during daylight hours. Press the TEST button,
the emergency lights will turn off. By pressing the test button again
the emergency lights will turn back on.
15. On-charger manual test: the unit also has a test button installed on
the charger module located on the bottom of the unit (See figure 7).
This is useful during maintenance, with the unit door open. The
button performs the same functions as the remote control.
Automatic self-test and diagnostic (Option)
16. Self-test: Once power is supplied to the unit it will automatically
initiate a routine self-test calendar as follows:
a. Verifies battery connection, battery failure, charger board failure
and lamps failure.
b. Executes one-minute monthly self-test
c. Executes a 30-minute self-test every 6th month
d. Executes a 90-minute self-test every 12th month
17. Diagnostic: The unit is equipped with a bi-color LED pilot light and
indicates the following status:
a. Green color: AC-on / self-test
b. Red color: Service alarm
A diagnostic label is placed on the unit cover.
Transfer time delay (Option)
This feature works when the AC power is restored: it keeps the
emergency lights "on" for a period of: 5, 10 or 15 minutes (factory set).
If the battery depletes before the end of the time delay, the lamps turn
off and the unit goes in stand-by mode.
The Time Delay feature can be enabled or disabled in the field with the
following procedure (See figure 7):
a. Make sure that the battery and the AC main power are both
disconnected.
b. Disconnect the jumper JP4 to activate the Time Delay
c. Continue with the standard installation
Audible service alarm (Option)
This function acts in case of a Service alarm by generating a beep
every two seconds.
During a service alarm the beep can be silenced by pressing the
remote control test switch.
The audible service alarm can also be permanently disabled in the field
by disconnecting the jumper JP7 (See figure 7).
