FPC-5V2 April 20193 | P a g e
The fire protection module FPC-5V2 is powered by an internal 3V battery capable of
providing the necessary amperage to activate a condensed aerosol fire suppression
generator.
The FPC-5V2 module is equipped with a battery monitoring feature. The battery status
is indicated by the three LEDs located on the front of the unit.
oThe green LED flashes every four seconds, indicating that the battery is in
good operating condition and is able to activate the aerosol generator when
required.
oThe yellow LED is illuminated when the battery voltage level has dropped but
is still able to activate the aerosol generator when required.
oThe red LED is illuminated when the battery is unable to activate the aerosol
generator and it is necessary to replace the battery immediately.
oWhen no LED is illuminated, either the battery is installed in reverse polarity or
it is fully discharged, or the unit is set in manual mode.
Figure 4: Battery status indicator.
The fire protection module FPC-5V2 can monitor the battery in both automatic
and manual mode. Automatic mode means that the battery monitor function of
the unit is operating continuously. Manual mode means that the battery
monitor function of the unit does not operate continuously but only operates by
pressing and holding the press switch located on the front of the unit above
the LED. Automatic mode and Manual mode operation can be adjusted by
changing the position of the "SW2" switch on the electronic PCB. When the
switch is in the ON - position the unit is in Automatic mode. When the switch is
in the OFF - position the unit is in Manual mode.
