on the wiring to the sounder circuits.
Power Trouble
Failure of the mains power or disconnection of the standby battery will cause the Trouble and Power Trouble LEDs to
light indicating an abnormality in the power supply to the fire control panel.
System Trouble
The System Trouble LED will light if the configuration memory has not been set or has become corrupt.
General Trouble
Will illuminate under any trouble condition. This LED will also light if the configuration option jumper (see figure 18)
has been left in the access level 3 position and the enable controls key has been removed from the front panel.
Lamp Test
All LED indicators can be tested at any time by pressing the Lamp Test button. The Enable Control key does not need
to be inserted to test the indicators. The buzzer can be silenced at any time by pressing the Buzzer Silence button. The
enable key does not need to be inserted to silence the buzzer.
Released Condition
The released pressure switch input is connected to a pressure switch mounted on the extinguishant cylinder that
operates when the extinguishant is released. This process activates the released indicator on the fire control panel.
The fire control panel is not in an activated condition when the extinguishant releases by mechanical means.
Low Pressure Switch
The Low Pressure Switch input on the fire control panel is connected to a pressure switch on the extinguishant
cylinder which will operate if the pressure in the cylinder falls below a set point. This will happen after the
extinguishant has been released but may happen before release through a leak.
The flooding zone trouble indicator will light and the buzzer will sound when this input is operated. The pressure
switch can be configured as normally open or normally closed via configuration option C2C (software version 1.2 and
above only).
