APPROVED MSFM A05-228-01 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. 2551THR with 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.

See NFPA 72 for more details on spacing requirements. A05-228-01 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. 5551R with 6″ base Specifications – 5551B, 5551R Dimensions Height: Diameter: Shipping Weight: Temperature Range: Humidity Range: Sensitivity 5551B: 5551R: 2.1″ (5.3 cm) detector in base 4.0″ (10.2 cm) installed in B501 base 6.1″ (15.5 cm) installed in B501B base 0.3 lbs.
