Temperature Rating of Rise Detection INSTALLING sensor must be installed in compliance with the control system installation manual The installation must meet requirements of the Authority Having Jurisdiction AHJ offer maximum performance when installed in com with the National Fire Protection Association NFPA NFPA 72 read the system wiring and installation manual thor This manual provides detailed information on sensor placement zoning and special applications Copies these manuals are available from System Sensor DESCRIPTION 5251B 5251RB and 5251H are intelligent sensors that a state of the art thermistor sensing circuit for fast These sensors are designed to provide open area with 50 foot spacing capability Model 5251B is a temperature sensor with 135 fixed temperature alarm 5251RB is a rate of rise temperature sensor with 135 temperature alarm Model 5251H is a high temperature with 190 fixed temperature alarm LEDs on each sensor light to provide 360 visibility of the indication The LEDs can be latched ON by code com from the panel for an alarm indication The LEDs can be unlatched to the normal condition by code command LED annunciator capability is available as an optional Part No RA400Z 5251B 5251RB and 5251H require compatible ad communications to function properly Connect sensors to listed compatible control panels only GUIDE wiring must be installed in compliance with the National Code applicable local codes and the Authority Hav Jurisdiction Proper wire gauges should be used The instal wires should be color coded to limit wiring mistakes and system troubleshooting Improper connections will pre a system from responding properly in the event of a fire power from the communication line before install sensors Wire the sensor base supplied separately per the wiring see Figure 1 Set the desired address on the sensor address switches Figure 2 Install the sensor into the sensor base Push the sensor into base while turning it clockwise to secure it in place After all sensors have been installed apply power to the unit and activate the communication line Test the sensor s as described in the TESTING section of manual RESISTANCE sensor bases have a tamper resistant capability When capability is enabled sensors cannot be removed from the without the use of a small screwdriver or other similar Refer to the sensor base installation instruction manual details in using this capability testing notify the proper authorities that the system is maintenance and will temporarily be out of ser Disable the system to prevent unwanted alarms sensors must be tested after installation and periodically Testing methods must satisfy the Authority Hav Jurisdiction AHJ Sensors offer maximum performance tested and maintained in compliance with NFPA 72 The may be tested in the following ways Test Magnet Model No M02 04 Place the magnet against the cover in the magnet test as shown in Figure 3 to activate the test feature The LEDs should latch ON within 10 seconds indicat alarm and annunciating the panel Reset the detector at the system control panel Direct Heat Method Hair dryer of 1000 1500 watts From the side of the detector direct the heat toward sensor Hold the heat source about 6 inches 15cm to prevent damage to the cover during testing 1 ANNUNCIATOR DO NOT LOOP WIRE UNDER TERMINAL 1 OR 2 WIRE RUN TO PROVIDE SUPERVISION OF CONNECTIONS 2 Rotary decade switches 0 0 A OPTIONAL WIRING The LEDs on the detector should light when the at the detector reaches the alarm set point the LEDs fail to light check the power to the detector the wiring in the detector base Reset the detector at the system control panel that fail these tests should be cleaned as described MAINTENANCE and retested If the detectors still fail tests they should be returned for repair Before cleaning notify the proper authorities that the is undergoing maintenance and therefore the system temporarily be out of service Disable the loop or system maintenance to prevent unwanted alarms is recommended that the sensor be removed from its mount base for easier cleaning and that sensors be cleaned at once a year Use a vacuum cleaner to remove dust from sensing
