FIRE ALARM ASPIRATION SENSING TECHNOLOGY
QUICK INSTALLATION GUIDE ADDRESSABLE FAAST LT
MODELS NFXI-ASD11, NFXI-ASD12, NFXI-ASD22
DESCRIPTION
The LT NFXI-ASD Series is part of the Fire Alarm Aspiration Sensing Technology® (FAAST) family. FAAST is an advanced
re detection system for use where early warning and very early warning are a requirement. The system continuously draws air from the controlled environment through a series of sampling holes to monitor the environment for smoke particulate.
The NFXI-ASD is the addressable version of the FAAST LT range,
protocol. It is available in 3 different models:
NFXI-ASD11 - Has single channel capability with one laser smoke
sensor.
NFXI-ASD12 - Has single channel capability with two laser smoke
sensors in a common chamber for coincidence detection.
NFXI-ASD22 - Has two channel capability with two laser smoke
sensors in separate chambers. (one sensor for each channel).
This guide provides information for mounting and basic installation using the unit’s default factory settings. For more advanced information please see the FAAST LT Advanced Setup and Control Guide.

Aspirating Smoke Detectors supplied and installed within the EU must conform to the EU Construction Products Regulation (CPR) 305/2011 and the related European Product Standard EN 54-20. FAAST LT has been tested and certied to ensure that it conforms to the necessary Standards, but strict adherence to this instruction guide is advised to ensure that the installation meets the requirements of the CPR.

The performance of this system is dependent upon the pipe
network. Any extension or modication to the designed
installation may cause improper operation. The operational
effects of such changes need to be veried using the PipeIQ
2 design software.
This equipment and all associated pipe work must be installed in accordance with all relevant codes and regulations.
PHYSICAL INSTALLATION
Front Panel Labels
The LT NFXI-ASD is shipped without the front panel labels xed in place. This allows the installer to choose the language required for the installation from the Front Panel Labelling Pack.

SETTING THE ADDRESSES POWERING UP
Each aspiration channel uses loop communications to report its status information to the CIE (Fire Panel). As a factory default, the unit will report smoke alarm and sensor information at an associated sensor address and general alerts and faults on a different module address.
Figure 10: Address Switches
Sensor
of the smoke sensing devices. The smoke sensors are located
under the sensor cover inside the unit (see Figure 9). The Smoke Sensors section of Service - later in the manual - shows how
to remove the sensors. As supplied, the default for channel 1 is Address 1; in 2 channel units (or when two sensors are tted) the
second device is set to Address 2.
Any sensor address may be used except 0, whilst respecting the panel’s rules on co-operative Multi-Sensing* (see below) between the VIEW™ smoke sensors.
Note: The sensors communicate with the re panel through the loop connection whether the 24VDC power supply is on or not.
Module
Note: The module address will only respond to a panel poll when in Normal mode with the 24VDC power supply on.
* Co-Operative Multi-Sensing
Depending upon the panel used, the rules to dene the co-operative Multi-Sensing between the VIEW™ smoke sensors differs. This mode will allow an even higher sensitivity, but is only to be used for the sensors within a single NFXI-ASD12.
How to Set this up for the NF300, NF3000, NF500, NF5000 and ID3000 Panels
The co-operative Multi-Sensing is automatically activated if the VIEW™ sensors on a loop are set to adjacent sensor addresses and if they are also put into the same zone. Additionally, if cells are being used, the cell numbers for the co-operative sensors must
also be the same.
How to Set this up for the NF50-A, NF50, NF50-S, ID60 and Pearl Panels
The co-operative Multi-Sensing is automatically activated if the VIEW™ sensors on a loop are put into the same AWACS group. Setting an AWACS group to 0 will disable co-operative Multi-
Sensing for that sensor.
Using Default Settings
1. Connect a suitable 24VDC supply (complying with European Standard EN 54-4) to pins 1 and 2 on terminal block T1 (See
Table 2)
2. Check the voltage at the connector. Make sure it is within the required voltage range.
4. Close and secure the housing door; verify the fan starts up and air ows out of the exhaust port. The unit takes 1-3 minutes to
initialise and stabilise in normal mode.
EXTERNAL RESET
The default setting for the congurable external input is Device Reset (terminal block T8). A short circuit connection between these terminals will cause the FAAST LT unit to perform a reset.

Exit from Maintenance Mode
To exit from the Maintenance mode, press the three front panel user interface buttons TEST, RESET and DISABLE simultaneously for 2 seconds. Alternatively, reset the unit using the Remote Input (when set to default value) or power the device off and on again.
If there is no activity in Maintenance mode for 5 minutes (default), the FAULT indicator blinks green for 15s and then the unit automatically returns to the Normal state.
TESTING
Note that the sensor LEDs, which are under the control of the CIE (Fire Panel), must be turned on to activate the front panel alarm
indicators.
Magnet Test
The alarm signalling can be tested for functionality by placing a test magnet in the position shown in Figure 9 (displayed earlier in the guide). This method does not test the air ow in the pipe-work.
Smoke Testing
The system alarm response can be tested for functionality using smoke. The choice of smoke source is dependant on the installation but in all cases the smoke must be present for the duration of the test. Smoke pellets or matches can be used close to the sampling point to introduce smoke particulates into the
N200-102-00 9 I56-3947-202

LASER SAFETY INFORMATION
The detector contains a Class 1 laser product. Radiation emitted inside the smoke sensor is completely contained within its housings and protective covers during all phases of operation.
WARNING
Using compressed air to clean the pipe system
High pressure air ushed through the system could damage
the fan, ensure that the FAAST LT unit is sealed or detached from the system before commencing this procedure.
USB CONNECTION
PC connectivity is provided by an on board USB B socket located centrally between the lter and the sensor cover (see Figure 9 displayed earlier in the guide). The USB interface allows access to a range of additional options via the PipeIQ 2 application software running on a PC.

GUIDA DI INSTALLAZIONE RAPIDA FAAST LT INDIRIZZABILE
DESCRIZIONE
La serie LT NFXI-ASD fa parte della famiglia FAAST (Fire Alarm Aspiration Sensing Technology®). FAAST è un sistema di rilevamento di incendi avanzato da utilizzare dove sono richieste rilevazioni di tipo “early warning” e “very early warning”. Il sistema aspira continuamente l'aria dall'ambiente controllato attraverso una serie di fori di campionamento per monitorare se nell'ambiente sono presenti particelle di fumo.
Il modello NFXI-ASD è la versione indirizzabile della gamma FAAST LT, che comunica con il CIE (pannello antincendio) tramite un protocollo proprietario. È disponibile in 3 diversi modelli:
NFXI-ASD11 - Ha un singolo canale a disposizione con un rivelatore
laser di fumo.
NFXI-ASD12 - Ha un singolo canale a disposizione con due rivelatori
laser di fumo in una camera comune per il rilevamento combinato.
NFXI-ASD22 - Ha due canali a disposizione con due rivelatori laser di
fumo in camere separate. (Un sensore per ogni canale.)

RELÈ
AZIONE:
NOTE
ALLARME 1 o 2
Attivato dal pannello quando rileva che è soddisfatta la condizione di allarme.
Impostato ON e OFF dal pannello;
senza memoria
GUASTO 1 o 2
Attivato quando si verifica una CONDIZIONE DI
GUASTO sul Ch1 o sul Ch2 o un GUASTO generico.
Un guasto viene segnalato anche quando il dispositivo
è in modalità di Assistenza o non è alimentato.
Stato di guasto senza memoria.
SIRENA 1 o 2
Attivato quando un canale è in ALLARME. La Sirena 1 corrisponde a Ch1 e la Sirena 2 a Ch2
Condizione predefinita = impostata su
ON in ALLARME.
Fissaggio morsettiere
Per inserire le morsettiere nell’unità utilizzare il seguente metodo:
1 Inserire un angolo della morsettiera nella fessura (vedere a).
2 Premere tutta la lunghezza della morsettiera nella fessura nché
non scatta in posizione, i due ganci superiori sulla morsettiera devono essere visibili (vedere c).

I carichi induttivi possono causare sovratensioni da commutazione che potrebbero danneggiare i contatti del relè del modulo (vedere sopra).
Per proteggere i contatti del relè, collegare un soppressore
di tensione transitoria (ad esempio 1N6284CA) al carico, come indicato.
In alternativa, per applicazioni CC non controllate, inserire un diodo con una tensione di scarica contraria 10 volte superiore alla tensione del circuito.
