GENERAL DESCRIPTION
Model 5251P is an intelligent sensor that utilizes a state-of-the-art thermistor sensing circuit for fast response. This sensor
is designed to provide open area protection with 50 foot spacing capability and is intended for use with compatible con-
trol 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).
