DET-TRONICS SPECIFICATION DATA Eagle Quantum EQ2200UVHT For Use With C7050B Continuous Duty High Temperature UV Flame Detector DESCRIPTION The EQ2200UVHT UV Flame Detector is used with the Eagle Quantum system to provide UV flame protection in continuous duty high temperature applications, such as turbine compartments, enclosures, generator rooms, etc. where ambient temperatures can continuously exceed +75 C (+167 F). The EQ2200UVHT is an electronic module assembly that is used in conjunction with a high temperature rated C7050B UV detector (with DE1888K3 high temperature rated UV sensor tube). The two devices are mounted in separate explosion-proof, watertight enclosures. The UV detector is rated for continuous duty in environments up to +125 C (+257 F). The electronic module is rated up to +75 C (+167 F). The electronic module cannot be located in the high temperature area. The UV detector and electronic module assembly can be separated up to 165 feet (50 meters) using high temperature rated 4 core shielded cable. In accordance with NFPA 72, the maximum separation distance is 20 feet (6 meters) using conduit or equivalent protection against mechanical damage. The detector is equipped with both automatic and manual optical integrity (oi) test capability. LED Detector status is indicated by a red LED that is visible through the viewing window on the cover of the electronic module junction box. Table 1 indicates the condition of the LED for each detector status. OUTPUT The output of the device is a status message that is sent to the gateway and logic controller in the Local Control Unit along the communication loop. System response to the message is determined at the time of configuration. The device supports ANSI/NFPA 72 Class A, Style 7 communication with the LCU. *oi is Detector Electronics' Trademark for its patented Optical Integrity Systems, U.S. Patent 3,952,196, United Kingdom Patent 1,534,969, Canada Patent 1,059,598.

Table 1 Detector Status/Indications Status Normal with automatic oi selected Normal with manual oi selected Fault Fire LED Blinks every 5 seconds Blinks every 10 seconds Off On ADDRESSABILITY Device identification is accomplished by setting switches on a DIP switch assembly located on the electronic module (valid address range is 5 to 250). ALARM LOG The detector maintains an alarm log in non-volatile memory. The time and date for the last eight alarms are logged. TERMINAL WIRING BOARD External wiring is connected to plug-in screw terminal connectors on the terminal wiring board located inside the electronic module junction box. ENCLOSURE The explosion-proof NEMA/Type 4X enclosure is designed for use in a variety of hazardous locations. SOFTWARE SELECTABLE OPTIONS The following software selectable options are available using a PC running Det-Tronics configuration software. Operating Mode The operating mode determines the type of logic that the UV flame detector will use for processing fire signals. (Arc rejection mode is the recommended setting). Arc Rejection Mode (Factory Recommended). The arc rejection mode enables the detector to prevent nuisance fire alarms caused by UV from short-duration electrical arcs or electrostatic discharge, while maintaining the ability to reliably detect the UV given off by a flame. The arc rejection mode is not recommended unless these false alarm sources are present within the application to be protected. Typical applications that benefit from arc rejection logic include electrostatic coating processes and uncontrolled environments where transient UV sources can be present, such as many typical outdoor applications. The arc rejection algorithm examines the radiant energy level detected within a specified unit of time (timed gate). The output of the detector is determined by three variables: sensitivity level gate length number of consecutive gates required. Different combinations of these variables allow for various levels of transient arc rejection capability. There are four arc rejection levels (very high, high, medium, and low) that are selectable for the detector through the PC. Refer to Table 2. The proper arc rejection setting for a given application must be determined through testing. For indoor applications with known electrostatic energy fields within 15 feet of the detector, an arc rejection setting of very high or high is typical. For outdoor applications, medium or low arc rejection settings are typical. It is recommended that each detector be thoroughly tested at the programmed arc rejection setting within the ambient conditions that will be present during normal operation. This will help to ensure that the selected arc rejection setting is proper for the application. Standard Mode. In the standard processing mode, the detector output (measured in counts per second) is compared to the fire threshold (the sensitivity setting as described below). If the radiant energy level from the fire exceeds the selected alarm threshold level, the time delay begins (if a time delay is selected). If the radiant energy level from the fire remains above the selected sensitivity level for the duration of the time delay, the fire alarm output is activated. In every application, it is crucial to ensure that the radiant ultraviolet energy level from the expected fire at the required distance from the detector will exceed the selected sensitivity level. Standard signal processing is recommended for controlled indoor applications only. 2

The selected sensitivity level determines the fire alarm threshold setpoint. The higher the sensitivity level, the greater the detection range, but the possibility of false alarms will be increased. Four sensitivity levels are selectable. Refer to Table 3. The sensitivity setting must be appropriate for the anticipated fire size at the required distance from the detector. Time Delay Arc rejection mode If the fire signal meets the programmed arc rejection requirements, the time delay begins. A fire output is generated if the fire signal continues for the duration of the time delay. Standard mode A fire output is generated only if the fire signal exceeds the sensitivity setting for the entire duration of the programmed time delay. Automatic or Manual oi The oi system uses an internally generated UV test signal to determine the relative condition of the detector and its optical surfaces. If automatic oi testing is selected, the oi test is automatically performed once every minute. The automatic oi test does not generate an alarm output or interfere with normal detector operation. The manual oi test is initiated using a button on the point display screen on the PC. The manual oi test can be used in addition to automatic oi to test UV detector sensitivity.

Replace the junction box cover and hand tighten to ensure proper sealing. UV FLAME DETECTOR Wiring to the UV detector must be between 12 and 18 AWG with a minimum voltage rating of 600 volts rms and a minimum temperature rating of 125 C. The use of shielded cable is highly recommended to provide maximum protection from RFI/EMI interference. 1. Mount the Swivel Mounting Bracket using 1/4 inch (M6) screws with a length of at least 1 inch (25 mm). The mounting surface should be free of BARREL WINDOW CAP Figure 10 Detector with Cover Locking Assembly vibration. Allow adequate space around the swivel to facilitate aiming and wiring of the detector. Armored flexible conduit should be used for the final 3 feet (one meter) of the cable run to allow for aiming and alignment of the detector. 2. Attach the detector to the Swivel Mounting Bracket. 3. Disassemble the detector enclosure by turning the housing cover counterclockwise. See Figure 9. If the detector is equipped with a cover locking device, it must be loosened using a hexagonal (Allen) wrench (see Figure 10). 4. Connect the wires to the appropriate screw terminals on the detector terminal block. See Figure 7 for terminal identification. Do not ground the shield to the detector housing.

Using the index pin as a guide, install the sensor module on the detector terminal block. 7. Re-assemble the detector housing. If the detectors are equipped with cover locking devices, loosen the clamp sufficiently so that the catch can be seated in the blind hole provided on the terminal cap. See Figure 10. The clamp must then be fastened securely around the detector barrel by tightening with the proper tool. 8. Clean the viewing window and oi ring. 9. Check the viewing window surface (Figure 11) and ensure that: A) The oi source (UV test lamp opening) is located on top. B) The split in the oi reflective ring is not aligned with the UV test lamp opening on the detector module. C) The split in the oi ring is directed downward to prevent a buildup of contaminants between the oi ring and the viewing window.
