Det-Tronics ADDENDUM xWatch® Explosion-Proof Camera with X-Series Flame Detectors Instruction Manual

ADDENDUM xWatch® Explosion-Proof Camera with X-Series Flame Detectors Description The xWatch® Explosion-Proof Camera is available as a factory installed option with any of the Det‑Tronics X‑Series line of flame detectors. With this arrangement, the camera and detector share the same field of view. This option is available with X3301 and X3302 Multispectrum IR, X5200 UVIR, X2200 UV and X9800 IR Detectors. The xWatch Surveillance Camera produces a high resolution color video picture using a camera module that is mounted inside an explosion-proof NEMA 4X rated housing. The device’s explosion-proof rating makes it suitable for Class I, Div. 1, Groups B, C and D locations. The xWatch video driver is designed for use with twisted pair cable of 100 ohm impedance. The best video performance in terms of distance, video quality, and cost is attained using 22 AWG to 16 AWG, twisted pair cable of 100 ohm impedance. The monitor end must terminate the video cable with 100 ohms. Since most monitors have a built-in termination resistor of 75 ohms instead of 100 ohms, a balun or other matching network (video converter) must be used. In the event of a fire or gas alarm, the operator can immediately view the monitored area to determine whether personnel are present and safe. An accurate evaluation of the hazard’s size, nature, location and severity can be determined quickly and safely. The use of a digital video recorder (DVR) to capture the event provides a permanent record for future analysis of what occured. A variety of matrix control systems or DVRs can be suitable for viewing or recording the video signal, depending on the requirements of the individual application. The detector’s auxiliary relay contacts are typically used to signal the video system of an alarm event. general application information Refer to Figure 1 for a schematic of a typical system. The xWatch has a balanced differential video output for driving a long distance twisted pair signal to a remote site for monitoring and/or recording. The video output format can be either NTSC (National Television Systems Committee) or PAL (Phase Alternating Line). 2.2 2.2 ©Detector Electronics Corporation 2009 1 5/09 95-8603 95-8603 EQP DVR LON DIFFERENTIAL VIDEO SIGNAL RELAY B2367 Figure 1—Schematic of a Typical System specifications Field of View— 90 degrees Operating Temperature— –20°C to +70°C User Interface— Conventional off-the-shelf video switchers and controllers can be used for the interface.

This may be accomplished using isolating active transceiving systems or passive video isolation transformers/baluns. Specify a baseband video isolation system with a frequency response of at least 25 Hz to 6 MHz. Small cable TV transformers will generally not work as their frequency response is not low enough. CAUTION Installation and wiring of the flame detection system should be performed only by qualified personnel. Refer to the flame detector instruction manual for general installation instructions. Video Cable Considerations Proper video cable will ensure that the best quality video is displayed on a remote monitor. Because composite video frequencies span the range of 25 Hz to 6 MHz, most cables will display transmission line characteristics. Ensure that the same cable type (impedance) is used throughout the entire length. For example, do not mix twisted pair cable and coaxial cable without using a balun for matching. In addition, the monitor end must be properly terminated. Failure to properly implement the video cabling system may result in smearing (loss of detail) and/or loss of color and/or loss of picture sync. Wiring procedure The xWatch employs a balanced differential video driver designed to drive twisted pair cable of 100 ohm impedance. The best video performance in terms of distance, video quality, and cost is attained using a 22 AWG to 16 AWG unshielded twisted pair cable of 100 ohm impedance. The wiring can be Category 2 or better, stranded or solid. 2. Connect the external wiring for the xWatch to the appropriate screw connectors on the terminal block. See Figures 4 and 5. caution Power must not be applied to the device while the housing is open. Attention Observe precautions for handling electrostatic sensitive devices. 1. With the housing cover removed, wire the flame detector as shown in the detector manual. Important Do not test any wiring connected to the xWatch with a meg-ohmmeter. Disconnect wiring at the camera before checking system wiring for continuity. The monitor end must terminate the video cable with 100 ohms. Most monitors have a built in termination resistor. If the monitor uses 75 ohms instead of 100, a balun or other matching network must be used. 3. Complete installation and commissioning of the system as described in the detector instruction manual. Coax such as RG-59 or RG-6 may be used, but be sure to use proper matching and termination devices. There are manufacturers who support driving many types of cable systems using active transceivers that compensate for cable losses. 9 4-20 mA + 19 4-20 mA – VIDEO + 29 8 4-20 mA + REF 18 4-20 mA – REF VIDEO – 28 7 COM FIRE 17 COM FIRE COM AUX 27 6 N.O.

Remove the housing cover from the xWatch. 2. Loosen the setscrew on the side of the xWatch module. See Figure 6. 1. Disassemble the enclosure by turning the housing cover counterclockwise. See Figure 7 for an illustration of the xWatch assembly. 3. Align the two notches on the face of the module so that they are level with the horizon or until the image on the monitor looks level. 2. Remove the existing camera module from the xWatch. 4. When proper orientation has been achieved, carefully tighten the setscrew. Do not overtighten. 3. Using the index pin as a guide, install the new xWatch camera module on the terminal block. TROUBLESHOOTING 4. Re-assemble the device housing. 5. Clean the camera lens if required. The xWatch camera is not designed to be repaired in the field. If it is determined that the problem is caused by an electronic defect, the device must be returned to the factory for repair. 2.2 6 95-8603 MAINTENANCE Replacement Parts cleaning Part Number Description The xWatch camera requires no periodic calibration or servicing.
