5 MAINTENANCE & CLEANING
There are not user-replaceable parts in the NANO. Take Electrostatic Discharge (ESD) precautions when opening the NANO. Always wear a properly grounded anti- static wrist strap. Avoid direct contact with any of the components or connectors connected to the printed circuit board. Never let the electronics come in contact with clothing. The ground strap cannot dissipate static charges from fabrics. Failure to follow accepted ESD handling practices could cause damage to the NANO. It is important to note that improper cleaning of the NANO 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.
6 KEY PROPERTIES
The NANO is not only developed for land based installations, but can also aplied in marine applications. It has a DNV-CG Type Approval in accordance the 0339 standard. The NANO solution 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 board (ETB). This ETB must be placed in a suitable enclosure outside, but in the immediate vicinity of the to protected room. The ETB/L is suitable for igniters with a resistance of max 2Ω. The ETB/H is suitable for igniters with a resistance of max 4Ω. 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 a engine bay or room to be released by an automatic fire detector. But the NANO has two fire zones suitable for connecting Apollo Orbis Marine approved fire detectors. The NANO 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 than as informative/exploratory only. By default, the NANO is set to only manual release, but can be changed to automatic & manual mode.
