K&G Nano MAR Marine Alarm & Extinguishing System

The K&G Nano Marine is a fire alarm & extinguishing system, designed to activate a modular electrically activatable aerosol extinguishing generator. The Nano is used in systems to protect engine rooms in vessels and yachts, in electrical cabinets or rooms or any other areas where the user needs to be able to suppress a fire quickly and effectively.

The Nano MAR systems consists of:
-Nano Fire & Extinguishing Panel
-Nano Extinguishers Terminal Box 5/10

The basis is the NANO control panel, which is placed on the bridge or in its vicinity. There are two Extinguisher Terminal Boxes (ETB), which must be placed outside, but in the immediate vicinity of the protected engine room.

Characteristics
– the electronics of the NANO, except the connections and the dipswitches, are sealed by potting, which make it suitable for use in a contaminated environment
–  can activate the extinguishing system either manually, or by means of the selected option, in single or double zone dependency fire detection alarm
– has VFC outputs for fire, fault, and ventilation off
– has a full monitored output for the releasing an extinguishing system and audio-visual alarm
– two full monitored fire alarm input groups’ (zones) for spot detectors or linear heat detection cable
– two full monitored alarm input groups for external extinguishing release and hold function
– double extinguishing release buttons to prevent unwanted releases
– extinguishing hold release button to postpone a release
– extinguishing release delay to prevent unwanted release
– additional option to override the extinguishing delay at manual release
– historic event log memory readable from a mini-USB port and RS 485 Modbus com port

Extinguishers Control
The K&G Nano has a Extinguishers Terminal Box, named ETB/MAR/BOX, and is specifically developed for aerosol systems. The terminal connection box is equipped with built-in security electronics (ETB), which ensure that all the igniters of the extinguishing units are activated. The ETB/MAR/BOX is further equipped with surge and reverse polarity protection. A red test LED shows that an activation has occurred. An end line and extinguisher disable switch are intended to disconnect the electrical activator from the extinguishing activation line.
