Definitions

  • the invention relates to a device for testing the function of smoke detectors the preamble of claim 1.
  • smoke detectors are generally known, they are used in fire alarm systems for the early detection of fires in the event of a fire detect smoke particles or aerosols and if necessary send a signal to manage a central process unit in which the signals are evaluated.
  • Optical smoke detectors based on the scattered light principle contain a radiation source and a radiation receiver arranged outside the direct radiation area of the radiation source, the presence of smoke or fire aerosol in the radiation area (Measuring chamber) is acted upon by scattered radiation and depending on the Strength of the scattered radiation emits electrical output signals that are in a smoke detector existing electronic circuit for alarm or evaluated to the central Process unit to be forwarded.
  • the light sources often work in pulses, cf. e.g. those in EP-B1-0'079'010 described smoke alarm system.
  • Fire alarm systems must be ready for operation over longer periods. During this Time the smoke detectors are the harmful effects of the surrounding atmosphere, e.g. Exposed to dust or corrosive fumes; in addition, the electronic Components, in particular the radiation source and the radiation receiver due to aging decrease in quality. It is therefore necessary to ensure the functionality of the Check smoke detectors at regular intervals.
  • halogenated hydrocarbons have proven to be the best (Propellants), which have a suitable boiling point and which from suitable, in so-called detector testers arranged storage containers directly into the smoke detectors are blown (see e.g. DE-B2-20'54'027). Due to the pressure loss when exiting A sufficient amount of aerosol is created to test the smoke detectors. By the The high vapor pressure of the halogenated hydrocarbons evaporates the blowing agent within a short time and the operational readiness of the detectors is not impaired.
  • a suitable for testing smoke detectors with halogenated hydrocarbons Detector tester consists of an open on one side that can be put over the smoke detector Housing whose volume is at least twice the volume of the smoke detector is, as well as by a container connected to the housing, which under pressure contains liquefied propellant and the one with the housing put on by hand or Automatically actuated spray valve, the nozzle of which leads into the interior of the housing.
