. NFPA standard 72 should also be referenced. For installation in Canada, use Model FDX-551RA and refer to
CAN/ULC-S524 and CEC Part 1, Sec. 32.

GENERAL DESCRIPTION

Models FDX-551R and FDX-551RA are intelligent sensors that use a state-of-the-art dual-thermistor sensing circuit for
fast response. These sensors are designed to provide open area protection with 50 foot spacing capability and are in-
tended for use with compatible control panels only.
Two LEDs on each sensor light to provide 360° visibility of the sensor indication. The LEDs can be latched on by code
command from the panel for an alarm indication. The LEDs can also be unlatched to the normal condition by code com-
mand. Remote LED annunciator capability is available as an optional accessory (Part No. RA400Z).

WIRING GUIDE

Refer to the installation instructions for the plug-in base being used. Bases are equipped with screw terminals for power,
ground, and remote annunciator connections. See Figure 1. Bases BX-501 (shown in Figure 1) and B501 are electrically
identical.
Some versions of Notifier
FDX-551RA is achieved only on the MEDIUM sensitivity setting. Settings of HIGH or LOW may cause an alarm earlier or
later than desired.

  • Page 2 NOTE: All wiring must conform to applicable local codes, ordinances, and regulations. NOTE: Verify that all sensor bases are installed and that the wiring polarity is correct at each base. WARNING: Disconnect the power from the loop before installing sensors. 1.
  • Page 3 B. Test sensitivity from the control panel. C. Direct Heat Method (Hair dryer of 1000 – 1500 watts) 1. From the side of the detector, direct the heat toward the sensor. Hold the heat source about 6 inches (15 cm) away to prevent damage to the cover during testing.
  • Page 4 WARNING THE LIMITATIONS OF PROPERTY PROTECTION HEAT SENSORS 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. They alarm when temperatures at the heat sensor reach 57°C (135°F) or when a change in temperature of more than 15°F per minute occurs.
