Extinguishing control unit
Make sure that:
• All field wiring is tested and correct and is connected (except the actuator and
power).
• The display PCB is connected via ribbon cable connector.
• SWT3 settings on the main PCB are correctly configured (see Table 1 below).
• Fuses have the correct ratings: F1 (6.3 A), F2 (2 A), and F3 (2 A)
Table 1: SWT3 settings
SWT3 Position
Switch 1 OFF
ON
Switch 3 ON
Switch 4 ON
OFF
[1] VR1 on the main board sets the activation delay for double knock automatic discharge
Bells/sounders
Make sure that:
• The fire alarm sounders (if connected to the ECU) are fitted with polarizing
diodes.
• The last fire alarm sounder in the circuit (if connected to the ECU) is fitted
with a 2K2 Ω EOL resistor.
If the fire alarm sounder is not connected to the ECU (for example, it's
connected to the fire alarm control panel), then connect a 2K2 Ω resistor
across terminals TB1.4 and TB1.5 on the ECU.
• The extinguishant discharge sounders are fitted with polarizing diodes.
• The last extinguishant discharge sounder in the circuit is fitted with a 2K2 Ω
EOL resistor.

Description
Extinguishant released signal not verified
Extinguishant released signal sensed via pressure switch in
extinguishant distribution piping and reported to panel
More time function to operate on the double knock automatic
actuation
With jumper L5 (on display board) OUT = No delay between MCP
activation and actual extinguishing
With jumper L5 (on display board) IN = Delay as per the setting of
VR1 of the display board between MCP activation and actual
extinguishing [1]
