INTRODUCTION

The NANO is designed as a stand-alone fire detection and extinguishant release panel to be used in systems for e.g., electrical cabinets, CNC machines, engine rooms, small areas, or with other equipment. The NANO 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.
The NANO is a combined fire alarm control panel and extinguishing release system and has two detection zones, whereby any, or all detection zones can contribute to the extinguishant release decision. Despite the fact that the current power consumption of many conventional automatic fire detectors allows more than 4 fire detectors to be connected to a single fire zone, this number should be limited to a maximum of 4.

RESERVATION

The NANO panel has been assessed using conventional (non-addressable) fire detectors, as mentioned in chapter 23 of NANO user manual version 2.3 of February 1, 2023, and chapter 21 of the Concise NANO user manual version 2.3 of February 1, 2023 A comparison was made between these widely used conventional fire detectors and generally well-known conventional (nonaddressable) fire detectors from other manufacturers. Based on underlying technical data, a list has been compiled of the fire detectors deemed compatible with the fire detectors used during the assessment. It is important to acknowledge that this observation was made on March 1, 2022, and that, unknowingly, the technical specifications of the compatible conventional (non- addressable) fire detectors may have changed or may even have been removed from the delivery program of the relevant manufacturer since this date. We cannot be held responsible for faults, errors or malfunctioning of a fire alarm/extinguishing system caused by fire detectors other than those used during the assessment. Always test the alternative fire detector of your choice for proper functioning on a NANO panel before application or installation.

LOW CURRENT

During the development of the NANO, low power consumption was given high priority. As a result, measures were taken to minimize power consumption without causing performance degradation. Components that can be connected to the NANO, therefore, have to be able to deliver high performance with a low power consumption level. The purpose of the NANO is to minimize the use of the emergency power supply during a main power failure. At the same time, the NANO must be able to continue to perform optimally in the event of a main power failure.

ALARM ZONES

The NANO is equipped with two detection zone inputs. The loop inputs are continuously scanned for fire or fault detection. The loops are set to the following values:

• RESISTANCE value of less than 100 ‘: FAULT
  RESISTANCE value higher than 100 ‘ and less than 1.5 k’: FIRE
  RESISTANCE value higher than 1.5 k’ and less than 8 k’: FAULT
  RESISTANCE value higher than 8 k’ and less than 12 k’: NORMAL
  RESISTANCE value higher than 12 k’: FAULT

The commissioning engineer should ensure that the detectors corresponding with the specifications below. The correct input voltage and alarm resistance values, and are suitable for application on the NANO. All monitored inputs are protected against short circuit and cable malfunction. The voltage of all monitored detection inputs is controlled by the NANO itself and are independent of the main power supply voltage.

CONVENTIONAL FIRE DETECTORS

Any automatic fire detector of another brand that works within the mentioned limitations is capable of operating and functioning on the NANO system. Automatic fire detectors other than those listed in chapter 9 must meet the following requirements to function reliably on the NANO panel. Always check the specification of the fire detector of your choice before installation.
8.1 INPUT VOLTAGE
A fire detector must operate within the voltage range of 8 – 15 Volt, specified by us. The NANO alarm zones 1 and 2 operate in the quiescent state within the voltage range of 8 – 15 Vdc. In the event of a fire alarm, the voltage range increases to 21,7 Vdc.
8.2 FIRE ALARM STATE
When an automatic fire detector is connected to the NANO fire zone input, the NANO calculates the alarm load resistance based on the alarm zone voltage and alarm current. The alarm current is limited to 80 mA. The alarm load resistance of the automatic fire detectors, in combination with the end of line resistor of 10 K«, must not be less than a total value of 130 Ohm.
8.3 ZONE QUIESCENT STATE
The quiescent current is another aspect. The end line resistance lies between 8 and 12 K«. A lower resistance on the line creates an increase in the current; a higher resistance creates a decrease in the current. The quiescent current of the most well-known automatic conventional fire alarms varies from 20 to 130 µA. Considering the requirements of sections 5.1 and 5.2, detectors within these limits are deemed applicable to the NANO without exception.

FIRE DETECTION DEVICES SUPPORTED BY THE NANO.

The list below includes conventional fire detectors that have been tested and proven to work properly on NANO. These conventional fire detectors have been used during the DNV approval sessions.

9.1 DETECTORS TESTED ON THE NANO
The list below includes conventional fire detectors that have been tested and proven to work properly on NANO.

9.2 DETECTORS NOT TESTED ON THE NANO
The list below includes conventional fire detectors that have not been tested and proven to work properly on NANO. However, based on the technical details and specifications, they could work well. However, test always the detector of your choice on the NANO before permanent installation.

THE SOUNDER/BEACON

The list below includes the sounder/beacon that have been tested and proven to work properly on NANO. This sounder/ beacon have been used during the DNV approval sessions.

The sounder/beacon type below has been tested on the NANO and is approved for such

Part no| Type| Brand
VTB-32EM-DB-RB/RL VTB| sounder beacon| Cranford

10.1 SOUNDER/BEACON CURRENT
Until recently, the highest power consumption of a sounder/beacon combination was initiated by the beacon component. But with the introduction of high-level LED technology, this is no longer the case. Within the framework of low power consumption, only a sounder/beacon combination that uses LED technology is recommended for connecting to the NANO. Always check the specification of the alarm devices before connecting it to the NANO.
Sounder/beacon operating outside the NANO limitations and specifications will NOT operate according to the specified values such as sound pressure and light output candela.

Outdated or replaced computers and electronics are valuable sources for secondary raw materials if recycled.
Dealers of the NANO system must comply with local regulations for waste separation applicable in the country where the supplier is located.
