Colour Status
Green Mains and/or batteries are present.
Yellow There is at least one fault on the SPS. Then the general fault
relay is also activated.
Yellow Mains is not present or its value is out of range.
Yellow • Batteries are not present; or
• Batteries voltage is out of range; or
• There is a charge failure; or
• The batteries resistance level exceeded the threshold.
Yellow Batteries resistance level:
• Low
• Medium
• High
• Both LEDs flashing: default threshold reached. A battery
fault is activated.
Green • ON: output 1/2 is power-supplied.
• OFF: output 1/2 is not power-supplied.
• Flashing: output 1/2 in fault mode (ex.: short-circuit or over-
load).
Green ON when the input is activated. Then output 1 is deactivated
(output 2 remains activated). This deactivation can be delayed
of 10 minutes depending on switch configuration.
General fault relay The general fault relay is activated when there is at least one fault on the SPS.
User input This input is used to activate or deactivate remotely the output 1. Input is activated when a
short-circuit is applied between two terminal pins.
Then output 1 is deactivated (output 2 remains activated). This deactivation can be delayed
by 10 minutes depending on switch configuration.
See 2 - Connection.
Example 1: This input can be used to deactivate output 1 during an alarm using a relay on
the fire panel.
Example 2: This input can be used to deactivate output 1 during mains failure using the
mains fault relay on the fire panel. It will maintain battery capacity for the output 2.
Self resetting electronic fuse Both outputs are protected by an electronic circuit breaker. In case of overload or short
circuit on an output, the voltage of this output is switched off. In this case the output LED
blinks. Every 30 seconds the power supply tries to power on voltage. If overload is no
longer present the voltage is resumed, else the output remains switched off until the next
try.
Control of internal resistor of
battery pack
The power supply checks periodically the internal resistor of battery and displays the result
on front LEDs. No LEDs turned off means low resistance. Two LEDs turned on means a
high resistance. If two LEDs are blinking then the threshold is exceeded and a battery
fault is activated. In this condition the battery is not able to supply high current within the
voltage range. Battery wires should also be checked in case of high internal resistor.
