1FOREWORD
This owner9s manual must be thoroughly read and understood before using and operating the NANO
MAR SYSTEM and is intended for end users. The NANO MAR SYSTEM and the associated connections
must be installed, commissioned, and maintained by a skilled, knowledgeable, and competent person
or organization that is appropriately qualified to perform this work and is familiar with the objective
of the equipment and the associated technical terminology.
2CERTIFICATION
The NANO MAR SYSTEM has successfully passed CE and FCC, EMC testing according to EN 50130, EN
61000, EN 55016, 47 CFR15-ICES-003, ANSI 63.4, IEC60945-pt11 and a DNV marine type approval
according the DNV Class Guideline 0339-2021, certificate TAA000037H. For that the NMS has endured
extensive environmental tests such as vibration, dry heat, damp heat and cold tests in accordance
with the requirements of the DNV-CG 0339 standard.
3INTRODUCTION
The purpose of the NANO MAR SYSTEM is to control and monitor a number of aerosol generators
mounted on a ship as part of a fire extinguishing system. The NANO MAR SYSTEM is a compact and
robust stand-alone fire detection-extinguishant release system designed to protect various
applications like electrical cabinets, engine rooms in vessels, yachts and other small areas or
equipment. The NANO MAR SYSTEM continuously senses its inputs and, in the event of a fire, gives
the correct output to enable a product specific fire extinguishing. The NANO control panel has two
fire detection zones, any, or all of which can contribute to the extinguishant release decision. In a
marine application, it9s NOT common for a fire suppression system to be released by automatic fire
detector. By default, the NANO control panel is set to only manual release, but can also be changed
to automatic & manual release via push buttons on the NANO control panel.
4MAINTENANCE &CLEANING
There are not user-replaceable parts in the NANO MAR SYSTEM. Take Electrostatic Discharge (ESD)
precautions when opening the NANO control panel or NANO ETB BOX. Avoid direct contact with any
of the components or connectors connected to the printed circuit board. Failure to follow accepted
ESD handling practices could cause damage to the NANO MAR SYSTEM. Before starting the cleaning
process, bring the system out of operation to prevent an unwanted fire extinguishing system release.
It is important to note that improper cleaning of the NANO control panel front can damage this panel
inhibit their ability to sense fire and activate the fire extinguishers. To remove dust and contaminants,
use nonalcoholic products which has been designed for that purpose.
Do not use high pressure or stream cleaners.

Owners’ manual |NANO MAR SYSTEM | January 1, 2023 | version 1.0 page 4
5KEY PROPERTIES
The NANO MAR SYSTEM consists of three components. The basis is formed by the NANO control
panel which is placed on the bridge or in its vicinity. Then there are two extinguisher terminal boxes
(ETB MAR BOX). The ETB MAR BOX must be placed outside, but in the immediate vicinity of the
protected room. One is suitable for connecting up to 5 extinguishers and one for connecting up to 10
extinguishers. From the ETB MAR BOX the cable leads to the KVB plug & play Stat-X extinguisher
installed in the volume to be protected. Just like on the front of the NANO control panel, on the front
of the ETB MAR BOX, we have applied two dual-action buttons for releasing extinguishing. The fire
extinguishers will be released, depending on the DIP switch (time) settings. In a marine application, it
is NOT common for a fire suppression system intended for an engine room to be released by an
automatic fire detector. But the NANO control panel has two fire zones suitable for connecting Apollo
Orbis Marine approved fire detectors. The NANO MAR SYSTEM can be set up so that fire alarms from
these Apollo fire detectors are detected, signalized, and reported on the NANO control panel, but
considered as informative/exploratory.
6FEATURES OF THE NANO MAR SYSTEM
6.1 ACOUSTIC ALARM
The NANO has an internal attention signal and a monitored output for external sounder/beacon.
6.2 EXTINGUISHANT RELEASE OUTPUT
The K&G NANO MAR SYSTEM is equipped with two activation techniques for the activation of a fire
extinguishing system. By default, the NANO control panel is programmed for the activation of
electrical igniters intended for aerosol fire extinguisher generators or activating an extinguishing
system with a solenoid.

6.3 HISTORIC EVENT LOG
The NANO control panel 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 function as
an USB stick.
6.4 COMMUNICATION PORT
The NANO control panel has a Modbus network connection. Modbus enables communication among
devices connected to the same network.
6.5 DIRECT RELEASE
When the timer settings are set to a delay (between 0 –35 seconds), the direct extinguish DIP switch
gives the choose to override the delay in case of a fire event. This function can be selected with DP1.
6.6 GENERAL FAULT RELAY
The general fault relay signalizes, any fault in the NANO SYSTEM. The general fault relay is energized
in quiescent state. In the event of a complete power failure, the general fault relay becomes inactive.
6.7 VFC FIRE RELAY ACTIVE IN SINGLE OF DUAL MODE ALARM
A single or dual FIRE indication can trigger the VFC relay. You can choice to have the potential free
contact active at the first or at the second fire alarm. This function can be selected via dip switch 5.
6.8 SINGLE OR DUAL ZONE
Usually, the extinguishing system is activated in the so-called two group-dependent status (avoiding
coincidence). Two fire conditions must be met before an extinguishing activation will be initiated.
6.9 EXTINGUISHANT RELEASE DELAY
Extinguishing delay is only useful in normally occupied spaces. For the delay timer settings, there are
3 Dip Switches 6,7 and 8, which can be set in steps of 5 seconds the delay time between 0 and 35 sec.
7NANO CONTROL PANEL FACIA
The NANO control panel has a clear and orderly
front panel, which indicate the system status of
the NANO MAR SYSTEM. The figure shows the

10 COMMON SETTINGS
In a marine application, it is NOT common for a fire suppression system intended for an engine room
to be released by an automatic fire detector but ONLY by manual release.
The most common Marine setting of the NANO MAR SYSTEM is based on marine rules and standards.
Under normal condition only the green Power LED and the Manual Only LED lite to indicate the system
is operating correctly. Ask your supplier for your system settings.
Example setting for a vessel’s engine room:
▪The extinguishing delay time is 20 seconds
▪The NANO MAR SYSTEM operate in the manual mode only
▪The use of automatic fire detectors is only informative
Example setting for an electronical cabinet or auxiliary space in a vessel
▪The extinguishing delay time is set between 0 and 35 seconds
▪The NANO MAR SYSTEM operate in the Automatic & Manual mode
▪Dual zone alarm for automatic extinguishing release
▪When release delay is programmed, the manual release is also delayed
