It can be used in locations with high ambient temperatures.The detector is made from welded stainless steel and is com-pletely sealed. It is not repairable and cannot be disassembled. The detector is set to a specific alarm temperature when it is made at the factory and the temperature cannot be adjusted.The detector electrically connects to its related equipmentthrough two terminal posts with internal threads. Stainless steel screws attach the wiring from the related equipment to the two terminals. The detector mechanically attaches to the monitored area by 3/4-14 National Pipe Thread (NPT) located on the head of the detector.The following details are shown on a detector head:•Customer Part Number •Customer Code•Part Number: 17343-124•Date Code: XXYY (where XX = year, YY = week)Schedule of Limitations for Ex Components:•The detector must be mounted in a suitably IEC Ex certified enclosure that complies with the appropriate requirements for zone 2 applications.•Maximum surface temperature is dependent onambient temperatures and must be determined in the finalassembly installation. The temperature rise of the outside of the shell should not exceed 2°C above ambient whencarrying the maximum power load of 62.5W (.5A, 125 VDC).Limitations for Class I Div I Group BCD Components:•The detector must be mounted in a certified enclosure with the appropriate Class, Division, and Group Ratings for the application.•The Fire/Overheat Detector has a color band on the end opposite the electrical connection points.

The box must have a 3/4 NPT opening to install the detector .The installer of the detector must supply a means to prevent non-permitted decrease of clearance per IEC60079-15, para-graph 6.7.Replacement parts must be the same part number as the part being replaced.Fastening of the fire detector is through the 3/4 NPT thread. Do not use any anti-seize thread locking compound or lubricant on the NPT threads. The installer must ensure that a proper ground connection is made to the IP 54 box-grounding termi-nal.Procedure1.Turn the detector clockwise into the related equipment’s 3/4 NPT opening a minimum of 5 full turns. Torque the detector to 20 lbf ft (27 Nm).2.Connect the related equipment’s system wiring to the detectors terminals with the No. 8-32 UNC-2A SS slotted hex head screws with integral washer . Make sure the wire connections do not touch each other . Torque the screws to a value between 20 and 25 lbf in. (2.26 and 2.82 Nm).3.Make sure that no objects touch the detector or can touch or damage it during usual system operation.4.Keep the detector free of contamination and unwanted materials. Refer to the Cleaning section.OPERATIONThe Fire/Overheat Detector’s outer shell is made of stainless steel that expands with an increase in temperature. It closely follows changes in the air temperature that surround it. Two inner struts, made of an alloy that expands at a lower rate than the outer shell, are sealed inside the outer shell. An overheat condition causes the shell to expand faster than the innerstruts. This makes the struts move together and make electrical connection through the contacts that are attached to the struts . The electrical connection of the contacts completes the circuit through the terminal posts on the end of the detector . Figure 2 shows a simplified diagram of the Fire/Overheat Detector oper-ation. When the shell and inner struts cool, the contacts open again.There are three conditions that can have an effect on the oper-ation of the detector , especially when a functional test of the detector is done. These conditions are:1.Temperature Overshoot: This condition can occur when the temperature of a detector increases far above its set-point range when heat is supplied too rapidly. This can cause the contacts to close before the specified tempera-ture range.2.Anticipation Effect: This condition causes the alarm circuit to close well before the alarm set-point. This condition is the result of the supply of high heat too rapidly.3.Temperature Undershoot: This condition occurs when the temperature of a detector decreases suddenly below its set-point range when made to cool too rapidly. The detec-tor should be air cool only.If possible, these conditions must be prevented, specially when tests of the detector are done.Figure 2.

You can use equivalent alternative items for those given in the table.Pretest InspectionBefore you test the detector , make sure that the detector’s visual inspection is acceptable. Refer to the Inspection section of this manual.No-Continuity TestDo the no-continuity test per the following procedure. Do the test at room temperature. If the test is unsatisfactory, replace the detector. Detector is not a repairable unit.Procedure1.Connect one lead of a digital multimeter (DMM) to one of the two terminals posts of the detector and the other lead of the DMM to the other terminal post. See the no-continuity test setup in Figure 3.2.With the DMM set to measure ohms (Ω) on the highest scale, read the resistance.3.The resistance value must read an open condition or infinite (∞).4.Disconnect the DMM from the detector .Figure 3. No-Continuity Test SetupInsulation Resistance TestDo the insulation resistance test per the following procedure. Do the test at room temperature. If the test is unsatisfactory, replace the detector . Detector is not a repairable unit.Procedure1.Connect one lead of a megohmmeter to the two terminal posts of the detector jumpered together. Connect the other lead of the megohmmeter to the detector shell. See the insulation resistance test setup in Figure 4.2.Set the megohmmeter to supply 500 VDC and measure the insulation resistance of the detector.3.The resistance must be 20 megohms (M Ω) or higher.4.Remove the power from the megohmmeter and disconnect the leads and jumper from the detector .Figure 4.

Refer to the Cleaning section.1.Examine the electrical connection terminals. Look for cracks or damage. If the connection terminals are damaged or cracked, discard the detector.2.Examine the electrical connection terminal screws. Look for damage to the screw threads and head. If damaged, replace the screws. Make sure the screws turn freely in the connection terminals. If the screws cannot be turned completely into the terminals, discard the detector.3.Examine the shell or tube of the detector. If there is a dent, scratch, or abrasion to the outer area, discard thedetector.Do not supply more than 25 lbf in.
