INTRODUCTION The NANO is a very compact and robust stand-alone fire detection-extinguishant release panel designed to protect various applications like electrical cabinets, CNC machines or engine rooms in vessels, yachts. Further all kind of vehicles and other small areas or equipment in which the user should be able to detect and extinguish a fire rapidly and effective. The NANO is a versatile fire alarm / extinguishing system with a high-performance level intended for small and compact system.
8 NANO In addition to the NANO intended for land-based installations, a NANO version is available with a DNV-CG Type Approval in accordance with the 0339-2021 standard. This NANO system consists of two components. The basis is formed by the NANO control panel which is placed on the bridge or in its vicinity. Then there is an extinguisher terminal box (ETB). This ETB box must be placed outside, but in the immediate vicinity of the to protected engine room.
9.5 DIRECT RELEASE When the timer settings are set to a delay (between 10 3 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 via DP1. 9.6 VEHICLE MODE 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.
10.2 EXTERNAL RELEASE INPUT The NANO has a separate input for an external release extinguishing button. The external release extinguishing button has the same function as the dual release extinguishing buttons (fire buttons) on the front of the panel. 10.3 EXTERNAL HOLD INPUT The NANO has a separate input for an external hold-off button. The external hold-off button has the same function as the internal hold-off button.
12.4 HOLD EXTINGUISHING RELEASE By pressing the hold button at the panel or external hold button, as long this button is pressed, the extinguishing release sequence will be halted and cause the yellow hold activated indicator flash. Release the Hold button shall re-start the countdown release timer from programmed time. 12.5 AUTOMATIC & MANUAL RELEASE OR MANUAL ONLY MODE The mode of the system can be toggled between Manual Only and Automatic & Manual by operating the MODE push button on the NANO.
13.4 COMMON FIRE In the event of a fire alarm from either the fire alarm detectors or the operation of the extinguishant release pushbuttons, the red general fire LED will illuminate. 13.5 FIRE ZONE ALARM Upon receipt a fire alarm condition caused by the activation of a fire detector, the red alarm indicator of the relevant fire alarm zone will flash. 13.6 Extinguishing released The red extinguishing released indicator lights continuously when the extinguishers are activated.
14 DIP SWITCHES 14.1 STANDARD SETTING 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 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.

17 CONNECTING USING THE EXTINGUISHER TERMINAL BOARD (ETB) The ETB is developed for use with the NANO and aerosol extinguishers. This terminal connection board is equipped with built-in security electronics, which ensures that all igniters of the extinguishing units are activated. Together with an end line switch, this option turns the NANO system into a complete and reliable fire detection and extinguishing system.

23 NANO EXTERNAL EXTINGUISHERS RELEASE & HOLD WIRING OPTION The NANO has a separate input for external extinguishing release and external hold-off button. 24 NANO EXTERNAL VTB-EM SOUNDER & BEACON WIRING OPTIONS By a single sounder beacon follow the connection diagram below. The recommended setting gives the best and deviating alarm signal compared to the usual evacuation alarm signal for example on vessels. In some cases, the installation of a second signaling device is necessary.
25 NANO EXTINGUISHERS CONNECTIONS A connection as shown with a junction box is technically possible. But it is not covered by our warranty. We can only guarantee the proper functioning of the NANO in combination with an ETB. Only an ETB has a bridge protection against a possible early blockage, which ensures that the activation current flows through all igniters at all times.
