ISTORIC EVENT LOG
The NCP has an historic event log memory of 10.000 events readable from a USB port. Connect an
USB cable between the Mini-B USB port and your computer. The device will act as an USB stick. You
operating system will create a new disk station. The files on the disk station are text files with logged
event. The event log system is only meant for viewing, monitoring, and
analyzing. The events are recorded without time and date but in order
of event. Each time the NCP reboots, a new file is created with a new
batch number in the name. Pressed control buttons, detailed alarm and
fault indications, and relay switching events are logged in the text files.

OMMUNICATION PORT
The NMS has a Modbus network connection. Modbus enables communication among devices
connected to the same network. A Modbus network consist of one master and a number of slaves
units, each with a unique address. For more information, see the MODBUS user manual.

IRECT RELEASE
When the timer settings are set to a delay (between 10
–
35 seconds), the direct extinguish PDS gives
the choose to override the delay in case of a fire event. If a fire alarm is detected, by the automatic
fire detectors of the NCP and the count-down timer is started, you can override the timer. By pressing
the dual release extinguishing buttons on the front of the NCP or the external release extinguishing
button on the NETB, the extinguishing releasing process starts without delay immediately. This
function can be selected via PDS 1.

EHICLE MODE
(
NORMALLY NOT IN USE IN MARINE APPLICATIONS
)
If the extinguishing system is intended for the protection of a vehicle engine bay, then a programmed
extinguishing delay must be disabled, when the vehicle is parked, and the driver leaves the vehicle.
A fire extinguisher delay is then of no use and should be overridden. As soon as the ignition switch is
used again, even for a very short moment, the system returns to the programmed state. In vehicle
mode, a single or dual (depending on the PDS position) fire alarm immediately release the
extinguishers without delay. In normal operation, the vehicle power the NCP at CP terminal 15 + and
14 - , which means that the engine is switched on. In vehicle mode, the + on CP 15 must be extend
with a + on CP 13. If the vehicle is parked and the driver removes the car key from the ignition lock,
then this should remove the voltage at CP 13 and thus eliminate any delay. When the vehicle function
(PDS 2) is enabled, the green power LED flashes at a different frequency than when switching to
secondary voltage. When the vehicle mode is not in use and there is no external back-up
battery/power supply available, connect battery inputs CP 17 and CP 18 in parallel on respectively
the power CP 14 and 15 to avoid a battery failure signal. This function can be selected via PDS 2.
Please note that the vehicle mode does not work in the only manual mode (12.5)

ENERAL FAULT RELAY
The fault relay is normally energized and will de-energize upon any fault condition including total loss
of power. This secures a complete fail-safe condition of the NMS in case of a fault condition.
