    Net Safety Monitoring Figure 6: DIP Switch Location ETECTOR ETUP YSTEM ENSITIVITY The UV/IRS fire detector can be adjusted to various sensitivity levels by setting the detector to respond at a predetermined detector count rate. The count rate is dependent upon the intensity of the ultraviolet/infrared radiation reaching the detector, which in turn depends on the type of fuel, temperature, flame size and distance of flame from the detector.

  • Page 22: Appendix A: Common Uv Absorbing Gases

    Net Safety Monitoring A: C UV A PPENDIX OMMON BSORBING ASES Since the UV/IR-A & UV/IR-AR fire detectors are designed to detect fires by responding to the ultra-violet (UV) and Infrared (IR) radiation they emit, it is very important to be aware of UV absorbing gases that may be present between the detector and the sources of potential fires. Small concentrations of these types of gases may not absorb enough UV radiation to cause a problem, but when higher concentrations of these gases are present the detectors may become blind as not enough ultra-violet radiation can reach them to activate an alarm.

    Net Safety Monitoring B: E (ESD) PPENDIX LECTROSTATIC ENSITIVE EVICE Electrostatic discharge (ESD) is the transfer, between bodies, of an electrostatic charge caused by direct contact or induced by an electrostatic field. —ESD The most common cause of ESD is physical contact. Touching an object can cause a discharge of electrostatic energy ! If the charge is sufficient and occurs near electronic components, it can damage or destroy those components.
