Honeywell Notifier NFXI-ASD11 Guía De Instalación Rápida

I 56- 3947- 202
DESCRIPTION
The LT NFXI-ASD Series is part of the Fire Alarm Aspiration
Sensing Technology (FAAST) family. FAAST is an advanced
®
fire 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,
communicating with the CIE (Fire Panel) via a proprietary loop
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.

Quick Installation 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 certified 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.
