Understanding the System The Dräger Flame Detector 1700 is an Ultraviolet detector (UV) The detector is an Ex d (Explosion proof) certied devices suitable for both indoor and outdoor applications. The detector is available in either an LM 25 grade aluminium or a 316 stainless steel housing. Principle of operation The Dräger Flame Detector 1700 model is a single spectrum optical detector. It is designed to sense a ame or re and subsequently trigger a warning system or activate some kind of extinguishing system. Status of the detector can be determined by a 0-20mA output (see ‘Current (Source) isolated signal Output’ section, page 16), relays, and also by an LED situated on the faceplate of the detector (see ‘LED status’, page 16). The detector operates by monitoring an area for the presence of radiation. The Dräger Flame 1700 monitors the ultraviolet spectrum. Detection level Detection of radiation in the UV channel will trigger an alarm. Detection Wavelengths The UV sensor uses wavelengths in the region of 0.185 to 0.26 microns. The sensor peak is at approximately 0.21 microns. Optical ame detectors respond to radiation emitted by aming res. The graphical representation below illustrates hydrocarbon re emissions. With reference to the UV detector mentioned before, the required frequency is labelled below. CO2 Q n WIR NIR UV P 0 4.4P Wavelength of interest are 0.21Pm (UV) 6 P 8 Intended Use Optical Test The detector employs test facilities to check window cleanliness and functionality of the electronics. This check is automatic with the option for manual operation via a manual 24V input terminal. See Detector Maintenance section. ! NOTICE The optical test r uns e very 3 0 minutes and t akes approximately 10 seconds during in which time flame detection is not functional. The Dräger Flame Detector 1700 performs a single sub test on the UV sensor. The UV section currently consists of a high voltage UV source. The test sequence is as follows: The UV source is activated; it is not modulated, as the UV sensor does not respond to rate of change of incident UV energy but on the absolute amount present. If the detector passes the UV test within 5 seconds the test is considered a pass and the detector returns to its detection mode. If the detector fails the UV test, this will be indicated by a yellow LED (see ‘LED Status’ section, page 16) Field of View The detectors have the following elds of view in the horizontal and vertical axis*.

The following are points to be considered: • A clear view of the area to be protected. • Mounting of detectors on vibration free structures to provide best performance. • Adequate number of detectors to cover the area to be protected. • Detectors positioned so that they operate within their recommended operating distance. • Type of re hazard presented. • Inuences that could absorb wavelengths i.e. certain gases. • Angle at which detector is positioned – This should always be downwards and at a minimum of 10° - 20°. In addition to the above, the following can aect the detector performance: The Dräger Flame Detector 1700 is an ultraviolet ame detector, and can be operationally aected by outside inuences. Oil, smoke, and solvent vapours in the atmosphere may cause attenuation; also Lightning, Arc Welding, and X-rays may cause false alarms. It is essential that the Dräger Flame Detector 1700 is situated in such a way that the above mentioned inuences do not disturb the functionality and correct operation. Detector mounting The mounting bracket should be secured to a structure free from vibration, and capable of holding the detector and bracket. It is essential that the points covered above are considered when mounting the detector. Dimesions in Millimetres (mm) 9 Installation of the Dräger Flame Detector 1700 Electrical Install Detector wiring Ensure that any power is switched o before connecting any cabling to the ame detector. The connections are made in the rear terminal compartment through suitably certied glands. To access the terminal connections release the terminal cover locking screw using a 2 mm hexagon key and unscrew the terminal compartment cover. The UV detector requires 24 Volts DC nominal supply voltage, also available are an isolated 4-20mA output and 3 relays. Refer to pages 11-13 for the correct terminal connections. When this equipment is installed within either: NEC 500 Class 1 Div 1 NEC 505 Class 1 Zone 1 Certied areas then it must be installed using type MC-HL cable (Metal Clad for Hazardous Locations). ! NOTICE Wiring must be in accordance with local regulations. No more than one conductor should be used in each terminal. Duplicate terminals are supplied to allow ‘daisy chaining’ of connections if required. Duplicate terminals are not supplied for 4-20mA connections, which cannot be ‘daisy-chained’. ! CAUTION Before replacing the terminal compartment cover ensure the threads are lightly lubricated using suitable non-setting silicone grease. Hand-tighten the terminal cover then tighten the locking screw with a 2mm hexagon key (see Technical Specification’ section). Finally the protective cover is tted over the housing, to do this: 1. Briey remove the detector from its mounting bracket by slackening the two M8 xing screws. 2. Fit the two sides of the cover around the detector itself before aligning together and tightening with the 4 securing screws. 3. Return the detector to its mounting bracket and secure into position by tightening the two M8 screws to the specied torque (see ‘Materials’ section). ENSURE THAT THE DEVICE IS COVERING THE CORRECT AREA Unused cable entries must be tted with appropriate certied stopping plugs before commissioning the detector. The detector is now ready for power on and set-up. 10 Installation of the Dräger Flame Detector 1700 Electrical Connections Each detector has a built in terminal block of 37 terminals providing for a number of output connections; • 4 terminals for 24v DC power • 2 terminals for 4 – 20mA output • 6 terminals for alarm relay • 6 terminals for fault relay • 6 terminals for spare relay • 2 terminals for manual test activation • 2 terminals for internal linking of cable screens (shields) • 2 terminals for passive components • 1 terminal for connection to the enclosure (housing) A 4-20mA current loop is provided along with an alarm relay and fault relay. A two input manual test input is provided which takes a 24V input (referenced to an external 0V, hence two inputs). This input allows the user to manually activate an optical test. There is also a pair of terminals (35 & 37) into which is connected a user dened passive component to allow for interfacing to a number of vendors re panels. ! NOTICE Where terminals 35 & 3 7 are not i nterfaced with a ny v endor pannels, but t he alarm is required, it is necessary to place a hard wired link between terminals 35 & 37. Each terminal is capable of accepting a suitably crimped/ferruled 2.5mm2 core wire. The detector also has an external earth (ground) connection capable of accepting 4mm2 wire.

These layouts are solely to provide a brief indication of typical setup strategies available for the Dräger Flame Detector 1700. Choice of strategy is the sole responsibility of the user. Diagram A The wiring in this example shows direct connections to achieve isolated 4-20 mA (current source). This setup provides a signal available for connection to an Analogue Control Card. An additional connection can be made by implementing a switch between 24V supply and pin 15 creating an optional Optics Check. Diagram B In similar fashion to ‘Diagram A’ the functionality here is also to provide a 4-20 mA output, however, this setup utilises a 3-wire operation. Notice by using this method pins 11 & 13 need to be linked together. As before, a switch can be linked between 24V and pin 15, thus providing an Optics Check. Diagram C This arrangement shows the setup available for connections to a re panel. It should be noticed that a link is required here between pins 7 & 31, but also a resistance is required between pins 20 & 22 and 35 & 37. (Please bear reference to ‘Terminal Connections’ section, page 13) Again, as before, an Optics Check switch can be added. For relay operation the resistors R.Fault and R.Alarm are selected in order to give a particular current value for the normal operation and alarm.

The system performs an internal test and system initialisation. An optical and hardware check is performed within the testing. If the device has correct functionality and displays a green LED, it is ready for re detection. However, if there is a hardware or optical failure within the device the yellow LED will illuminate to indicate a problem. This will stay illuminated until the problem has been addressed and remedied by the operator. Detector Signals The Flame detector generates a 0-20mA signal to indicate its status (see Maintenance section); this should be checked during the installation of the detector. Alternatively the status and operation of the device can be monitored by the colour of the LED illuminated. Status Indicators Each detector provides the following status indications: 1. Healthy, green steady 2. Fire, red steady. 3. Optical fault, system fault, yellow steady The ‘Status LED’ table describes the visual indications provided by the status LED. LED Status System Status LED Status Power On / Running Green LED indicates successfully running System Fault / Failed optical check Yellow LED indicates a system hardware fault or optical failure Flame / Radiation Detected Red LED indicates a hazard has been detected Current (Source) isolated signal output 16 Current Output Status of Dräger Flame Detector 1700 0 mA Fault 1.9 mA ± 0.15 mA Optical Fault 3.8 mA ± 0.23 mA Normal 15.6 mA ± 0.40 mA Warning 20.09 mA ± 0.45 mA Fire Visual Indicator Maintenance Maintenance Detector Maintenance Once installed there are no user serviceable parts within the detector. The only servicing requirements are to ensure that the detector is fully functional (see section ‘Current (Source) isolated signal outputs) and to ensure that the lenses are clean. As mentioned earlier the terminal compartment cover and front cover threads must be lightly lubricated with nonsetting grease prior to re-assembly. The detector outer cover (weather shield) is moulded polycarbonate/abs and is not antistatic. CLEAN ONLY WITH A DAMP CLOTH. When replacing the detector front cover assembly it is essential for the function of the detector that the calibration bar in front of the lens is HORIZONTAL when the cover is in place (see diagram below). To do this hand tighten the front cover and then back it o a maximum of half a turn until the two locking screws are aligned with the slots in the front face of the detector housing. Tighten both locking screws to the specied torque setting using a 2mm hexagon key (see ‘Materials’ for settings) Correct Horizontal Test Bar Orientation äger Flame Dr !
