The NGA-401 Analogue Addressable Photoelectric Smoke
Detector have been designed to be fully compatible with the
Nortech Global range of intelligent control panels.
Compliant to EN54-5 and 7, the NGA series detectors are available in Optical, Heat and combined Smoke/Heat detector
versions.. Optionally they can be fitted with a short-circuit loop
isolator.
FEATURES
► Dual LEDs for 360° visibility
► Advance detection and communication protocols
► Easy installation and maintenance
► Sleek low-profile housing
► Durable sensor head, no need for replacement
► SMD circuit board design. High quality and reliability guaranteed

NGA – 800 is a single loop Analogue Addressable control panel
which can be expanded to two loops. It provides a cost effective
solution for small to medium sized installations. NGA – 800 can
support up to 125 addressable devices on each loops.
Using Nortech advanced communications mechanism, up to
32 individually addressed Loop sounders can be connected to
each of NGA – 800 detection Loops.
The panel is equipped with a backlit LCD display of 4 rows each with 40 characters to give clear textual
indications of fire / fault occurences to the end user. /there are also 16 Zone Fire LED indicators.
NGA – 910 Repeaters and MIni-repeaters can be connected via an RS422/RS485, Fibre Optic or
TCP/IP interface to facilitate remote display and control of the system.
An interactive graphic representation of the system can be displayed on the user’s computer via
NGA-905 graphical software (optional). All the devices on the system can be displayed on a building
plan showing their status in real time. In the event of fire or fault the customer can control the system
and access all the necessary inforamtion with a few mouse-clicks.
Automatic Device Detection at start up reduces time spent at the commissioning stage. In Installation
mode NGA-800 detects and recognises addressed and connected devices with the system being fully
operational in less than two minutes.
The default programming ensures that the system is ready to detect Fire/ Fault alerts from the moment
that power is applied. Additional programming to customise the system can be implemented using a
laptop PC running the NGA – 900 connector software.

NGA-600 is a powerful Analogue Addressable Fire Alarm Control Panel with networking capabilities that facilitate the configuration of complex Wide Area Fire Detection Systems. Modular
construction and distributed intelligence allow systems of up to
96 loops to be constructed. With a High level built-in redundancy and emergency back-up features, the NGA-600 is fully
equipped to control the most complex isntallations.
Using its wide array of interfacing capabilities the NGA-600 is ideally placed to provide an efficient and effective solution to the logistics of protecting large institution.
NGA-600 is available as a standalone system of up to 13 loops in a single cabinet
and can be expanded to up to 96 loops via a networked array of sub-panels which
can be supplied in a blank box version or combined with a repeater to allow remote
display and control of the system. Networking is done by a monitored, redundant,
double RS422/RS485, Fibre optic loop or TCP/IP network.
