General Description
All 500 Series sensors are simple to install, service, and
maintain. Using a specially designed tool (XR5),
maintenance personnel can easily remove and replace the
plug-in detectors without using a ladder. 500 Series
sensors incorporate built-in identification allowing the
system to identify the type of sensor. They also have a
built-in magnetic reed switch for local testing, and the
1551B, 2551HR, and 2551THR can be sensitivity tested
with the MOD400R Field Sensitivity Test Tool.
2551HR/2551THR
The 2551HR Intelligent Photoelectronic Sensor represents
the state of the art in smoke sensor technology. It features
fully coated circuit boards, special insect and dirt
protection and superior RF/transient protection. The
sensor will transmit an analog value representative of the
sensitivity that can be used by the system to determine
when maintenance is required. Signal processing for alarm
verification can be built into the system to provide
immunity to false alarms.
The 2551THR Intelligent Photoelectronic Sensor adds a
thermal heat collector that will alarm at a fixed
temperature of 135° F.

4″ base
1551B
The 1551B Intelligent Ionization Smoke Sensor’s unique
unipolar chamber responds quickly and uniformly to the
broadest range of fires and can withstand wind gusts up to
1500 feet-per-minute without outputting an alarm level
signal. Because of the unipolar chamber, the 1551B is
more responsive than most ionization sensors. This makes
it a more stable detector.

5551B/5551R
The 5551B Intelligent Thermal Sensor’s unique dual
thermistor sensor will alarm at a fixed temperature of
135° F.
The 5551R Intelligent Thermal Sensor will alarm at
135° F and at an increase in excess of 15° per minute. This
enables the heat detector to communicate an alarm to the
central control panel prior to reaching the static set point,
providing a timely response to rapid temperature
increases.
