INSTALLATION AND MAINTENANCE INSTRUCTIONS
ENGLISH
FOR MODEL NFX-OPT / NFXI-OPT PHOTO
ELECTRONIC SMOKE SENSOR
GENERAL DESCRIPTION
Models NFX-OPT and NFXI-OPT are intelligent plug-in type smoke sensors that combine
a photoelectronic sensing chamber with addressable communications. These sensors
are designed for open area protection and must only be connected to control panels
that use a compatible proprietary communication protocol for monitoring and control.
The NFXI-OPT sensor contains an isolator, if installing this version check the panel
documentation for details of how many isolators can be used on a loop.
Two LEDs on each sensor light to provide a local 360
of LEDs are dependent on panel). Remote LED indicator capability is available as an
optional accessory wired to the standard base terminals (again dependent on panel).

Independently tested and certified to: EN 54-7: 2018 (and EN 54-17: 2005 for NFXI)
WIRING GUIDE
Refer to the installation instructions supplied with the plug-in sensor bases for wiring de-
tails. All bases are provided with terminals for power and an optional Remote Indicator.
Note 1: All wiring must conform to applicable local and national codes and regulations.
Note 2: Verify that all sensor bases are installed and that polarity of the wiring is correct
at each base.
Disconnect loop power before installing sensors. Notify proper authorities.
SENSOR INSTALLATION
1. Set the sensor address (see figure 1) by turning the two rotary switches on the
underside of the sensor, selecting a number between 01 and 159. (Note: The
number of addresses available will be dependent on panel capability, check the panel
documentation for information on this). Record the address on the label attached
to the base.

2. Insert the sensor into the base and rotate it clockwise until it locks into place.
3. After all the sensors have been installed, apply power to the system.
4. Test the sensor as described under TESTING.
5. Reset the sensor by communication command from the panel.
Tamper-Resistance.
These sensors includes a feature that, when activated, prevents removal of the sensor
from the base without the use of a tool. Refer to the installation instructions for the
sensor base for details of how to use this feature.
Dust covers help to protect units during shipping and when first installed.
They are not intended to provide complete protection against contamination
therefore sensors should be removed before construction, major re-decoration
or other dust producing work is started. Dust covers must be removed before
system can be made operational.

MAINTENANCE
Before cleaning, disable the system to prevent unwanted alarms:
1. Remove the sensor to be cleaned from the system.
2. Gently release each of the four cover removal tabs that hold the cover in place (see
figure 2) and remove the sensor cover.
3. Vacuum the outside of the screen/chamber cover carefully without removing it.
4. Remove the screen/chamber cover assembly by pulling it straight out.
5. Use a vacuum cleaner and/or clean, compressed air to remove dust and debris from
the sensing chamber and sensing chamber cover.
6. Re-install the sensing chamber cover by aligning the square and round holes on the
cover with the square and round pins around the sensing chamber, gently pressing
it home until it slips into place (Note: Arrows on the plastic indicate the positioning
when replacing the chamber cover and air guide.
7. Re-install the sensor cover. Use the cover removal tabs and LEDs to align the cover
with the sensor. Snap the cover into place.
8. When all sensors have been cleaned, restore power to the loop and test the sensor(s)
as described under TESTING.
TESTING
Sensors must be tested after installation and following periodic maintenance. Disable
the zone or system undergoing maintenance to prevent unwanted alarms.
Test the sensors as follows:
Magnet Method
1. Test the sensor by positioning the test magnet (model M02-04-00 optional) against
the sensor body approximately 2 cm from LED 1, indicated by a mark on the sensor
cover as shown in figure 3.
2. Both LED's on the sensor should latch into alarm within 30 seconds, activating the
control panel.
Figure 3: Test Magnet Position
Smoke Method
1. Using generated smoke, or synthetic smoke aerosol from an approved manufacturer
such as No Climb Products Ltd, subject the sensor to controlled amounts of smoke
in accordance with local codes of practice and manufacturer recommendations.
2. Both LED's on the sensor should latch into alarm within 30 seconds, activating the
control panel.
After completion of the test notify the proper authorities that the system is operational.
Smoke sensors must be used in conjunction with compatible equipment.
Smoke sensors will not sense fires which start where smoke does not reach the sensors.
A sensor may not detect a fire developing on another level of a building.
Smoke sensors also have sensing limitations. Consideration must be made of the
environment when selecting fire sensors.
Smoke sensors cannot last forever. Smoke sensors contain electronic parts. Even
though sensors are made to last over 10 years, any of these parts could fail at any
time. Therefore, test your smoke detection system at least semi-annually. Clean and
take care of your smoke sensors regularly. Taking care of the fire detection system you
have installed will significantly reduce your product liability risks.
