INSTALLATION AND MAINTENANCE INSTRUCTIONS FOR MODEL
FDX-551EM PLUG-IN INTELLIGENT FIXED TEMPERATURE SENSORS
Before installing the sensor, please thoroughly read System Sensor's wiring and installation manual, "Guide to Intelligent Fire Systems". This
manual includes detailed information on sensor spacing, placement, zoning, and special applications. Copies of this manual are available at no
charge from Notifier.
GENERAL DESCRIPTION
Model FDX-551EM intelligent fixed temperature (Class A1S) sensors use a state-of-the-art single thermistor sensing circuit to provide early
warning of developing fires. These sensors are designed for open area protection and must only be connected to control panels that
use a compatible proprietary analogue addressable communication protocol for monitoring and control.
Two LEDs on each sensor light to provide a local 360° visible sensor indication. The LEDs can be latched on by code command from the control
panel for an alarm indication. The LEDs can also be unlatched to the normal condition by code command. Remote LED indicator capability is
available as an optional accessory wired to the standard base terminals.

WIRING GUIDE
Refer to the installation instructions supplied with the plug-in sensor bases for wiring details. All bases are provided with terminals for power,
shield, and an optional Remote Indicator.
Note: All wiring must conform to applicable local national codes and regulations.
Note: Verify that all sensor bases are installed and that polarity of the wiring is correct at each base.
Disconnect loop power before installing sensors.
SENSOR INSTALLATION
1. Set the sensor address (see Figure 1) by using a flat blade screwdriver to turn the two rotary switches, selecting the desired number
between 01 and 99. Record the address on the label attached to the base.
2. Insert the sensor into the base and rotate it clockwise with gentle pressure until it drops into place.
3. Continue to rotate the sensor until it locks into the base.
4. After all sensors have been installed, apply power to the system.
5. Test the sensor as described under TESTING.
6. Reset the sensor by communication command from the panel.

MAINTENANCE
Before cleaning, notify the proper authorities that the system is undergoing maintenance and will be temporarily out of service. Disable the
system to prevent unwanted alarms.

TEST

It is recommended that the sensor be removed from its mounting base for easier
cleaning and that sensors be cleaned at least once a year. Use a vacuum cleaner to
remove dust from the sensing chamber.
TESTING
Detectors must be tested after installation and following periodic maintenance.
However, before testing, notify the proper authorities that the system is undergoing
maintenance and the system will be temporarily out of service. Disable the zone or
system undergoing maintenance to prevent unwanted alarms.
In addition, check to ensure that the LEDs blink (if this feature is operational under
software command). If they do not, power has been lost to the sensor (check the
wiring), or it is defective (return it for repair).
Test the sensors as follows:
Test Magnet (Model M02-24 - optional)
1. Test the sensor by positioning the optional test magnet against the sensor body
approximately 2 cm from LED in a clockwise direction, as shown in Figure 2.
2. Both LEDs should latch on within 30 seconds, indicating an alarm and
activating the panel.
Control Panel
1. Test the sensitivity from the control panel.
Direct Heat Method (Hair dryer of 1000-1500 watts).
1. Direct the heat toward the sensor from its side. Hold the heat source about 15
cm away to prevent damage to the cover during testing.
2. The LEDs on the sensor should light when the temperature at the detector
reaches 58°C. If the LEDs fail to light, check the power to the sensor and the
wiring in the sensor base.
3. Reset the sensor at the system control panel.
After completion of all tests notify the proper authorities that the system is
operational.
Sensors that fail these tests should be cleaned as described under MAINTENANCE and retested. If the sensors still fail these tests they should
be returned for repair.
Heat sensors are designed to protect property, not life. They do not provide early warning of fire and cannot detect smoke, gas, combustion
particles or flame. The FDX-551EM alarms when temperature at the heat sensor reaches 58°C. Given the rapid growth of certain types of fire,
heat sensors cannot be expected to provide adequate warning of fires resulting from smoking in bed, inadequate fire protection practices, violent
explosions, escaping gas, improper storage of flammable liquids like cleaning solvents, other safety hazards or arson.
Heat sensors do not always detect fires because the fire may be a slow smouldering, low-heat type (producing smoke) or because
they may not be near where the fire occurs or because the heat of the fire may bypass them. Heat sensors will not detect smoke, gas,
flames or combustion particles.
Heat sensors are components in professionally installed fire alarm systems. They will not function if they have been improperly wired into
the fire alarm system or if power to them is cut for any reason.
Heat sensors cannot last forever. They should be tested and maintained following the instructions in this manual. To be safe, they should be
replaced after they have been installed for 15 years.
