INSTALLATION AND MAINTENANCE INSTRUCTIONS
Intelligent Plug-In Model 5251RP
Rate-of-Rise Temperature Sensor
with Fixed Temperature Alarm
Before installing sensors, refer to NFPA 72, and 101 (Life Safety Code) for information on sensor spacing, placement, zon-
ing, and special applications.
GENERAL DESCRIPTION
Model 5251RP is an intelligent sensor that utilizes a state-of-the-art thermistor sensing circuit for fast response. This sen-
sor is designed to provide open area protection with 50 foot spacing capability and is intended 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).

If the LEDs fail to light, check the power to the detector and the wiring in the detector base. 3. Reset the detector at the system control panel. Detectors that fail these tests should be cleaned as described under MAINTENANCE and retested.
