- Page 17 Installation of the Dräger Flame Detector 5000 It is not necessary for the DC power cable to be a twisted pair or individually screened, a 2-core stranded cable with an overall screen is suffi cient. The minimum conductor size is determined by the cable length, the number of Flame Detectors on each loop, and the maximum allowed voltage drop at the last detector.
- Page 18 Installation of the Dräger Flame Detector 5000 Equation 2: Characteristic Impedence Calculation = Cable Impedance (mH) = Cable Capacitance ( F) = Characteristic Impedance (Ohms) The RS485 communications cabling should be a twisted pair stranded cable with an overall screen. Where multi- core cables are used then individual screened twisted pairs are recommended.

Page 20: Operation
Operation Operation Detector Start-up procedure When the power is initially turned on there is a delay of approximately thirty seconds. The system performs an internal test and system initialisation. Detector Signals The Flame detector generates a 0-20mA signal to indicate its status, or provides relay outputs. This should be checked during the installation of the detector. -
Page 21: Maintenance
Maintenance Maintenance Detector Maintenance WARNING Repair of all equipment should be only performed in a safe area and by trained personnel. Once installed there are no user serviceable parts within the detector. The only servicing requirements are to ensure that the detector is fully functional and to ensure that the lenses are clean. The terminal compartment cover and front cover threads must be lightly lubricated with non-setting grease prior to re-assembly. - Page 22 Fault Finding • Check the ‘O’ ring seal on the enclosure cover to ensure that it is not damaged or perished; replace as required. NOTE: That the ingress protection is compromised if the seal is not correct. • Clean the enclosure faceplate (inside) with a mild detergent solution and a soft cloth until the window is clear of all contamination.
