Definitions

  • a fire alarm device in particular a smoke alarm device, with a housing and a self-checking device for testing the permeability of openings in the housing of the fire alarm is described.
  • the openings are in particular the smoke inlet opening.
  • the invention relates to a method for checking its functionality.
  • Fire alarms are used in apartments or in apartment-like used rooms to warn people present at an early stage against fire or smoke so that they can respond to the risk event adapted.
  • the installation of trained as smoke detectors fire alarms in apartments in new buildings and in the housing stock is required by law.
  • smoke detectors According to standard DIN 14676 "Smoke Alarms for Residential Buildings, Apartments and Rooms with Residential Use - Installation, Operation and Maintenance", smoke detectors must be subjected at least once a year to a visual and functional test. These tests are usually carried out manually by qualified personnel at the installation site in the apartment, but can also be carried out by the apartment user himself. They usually consist of a visual inspection and a function or alarm check.
  • For the function or alarm check is for example from the DE 10 2004 015 039 A1 a fire alarm system with a separate test device, which simulates the fire by generating an artificial flue gas cloud and checks whether the fire alarm triggers.
  • an optically operating smoke detector with a self-diagnosis is known, with which it is checked whether the smoke detector system operates within its calibration limits.
  • a self-diagnostic circuit based on a microprocessor is provided, which periodically checks the sensitivity of the optical receiver electronics for smoke noise or smoke obscuration levels.
  • the additionally provided according to DIN regulation visual inspection can not yet be carried out automatically. During this visual inspection, it should be checked whether the smoke intrusion openings are free and there are no mechanical damages to the fire alarm. In case of contamination of the smoke intrusion opening then cleaning and mechanical damage replacement of the fire alarm is provided. In addition to these requirements of the DIN regulation, it makes sense to check that the installation conditions of the fire alarm were not changed so that the intended use is no longer guaranteed.
  • the visual inspection usually takes place during an inspection of the apartment.
  • a test substance for example a test aerosol, with which an automatic test using the test substance - even without inspecting the dwelling - is possible.
  • the visual inspection must be carried out by the dwelling user himself - with all its disadvantages, because the non-specially trained dwelling user often does not properly recognize possible damage to the fire alarm.
  • the manual visual inspection thus has the disadvantage that it must be performed at the installation of the fire alarm.
  • the examination by the home user involves the risk of improper implementation.
  • compliance with the prescribed by the standard maximum maintenance interval, especially in the latter case can not be ensured.
  • the effort associated with the manual visual inspection in most cases, also means that the prescribed maximum maintenance interval is usually largely exhausted. A more frequent than an annual function and visual inspection is practically impracticable from a cost point of view and thus the associated higher reliability of the fire alarm can not be achieved.
  • the purely manual visual inspection also has the disadvantage that from the outside, the smoke-penetrating openings are partially not (completely) visible and can be closed only indirectly on the degree of contamination of the entire device on the state of the smoke intrusion.
  • test substance The sometimes already automated functional tests using a test substance are very expensive because a separate test substance must be kept in the device. Since the test substance is consumed during the functional tests, the use of such test substances also does not allow reliable maintenance-free operation over the entire service life, especially not if regularly and possibly more often than prescribed functional tests are to be performed.
  • Another problem is that it is not determined by the absence of visual inspection, if the fire alarm is increasingly polluted, so that no preventive cleaning can be carried out in advance of the occurrence of a malfunction.
  • Object of the present invention is therefore to automate a visual and functional test in the smoke alarm.
  • a fire alarm with the features of claim 1 and a method for checking its functionality with the features of claim 13.
  • at least one sensor is provided for this purpose, which optically and / or acoustically scans the at least one opening of the fire alarm.
  • most malfunctions of fire alarms are due to non-permeable openings in the housing of the fire or smoke detector. This may be due to increasing contamination over time of the inlet openings or arranged in the inlet openings grid, a delivery of the fire alarm with furniture, masking of the openings with tape in the renovation of a dwelling or the like.
  • Such causes of malfunctions of the fire alarm can be particularly simple and inexpensive with the inventively proposed optical and / or acoustic sensors recognize, as these require, in contrast to a test using test aerosol no additional test materials that may need to be replaced in regular manual maintenance.
  • distance sensors and / or light sensors are suitable as inventively preferred sensors.
  • the light sensors measure the incident through the at least one opening of the housing of the fire alarm light intensity and check in this way the permeability of openings in the fire alarm by means of optical scanning.
  • Distance sensors measure the distance of an object to the sensor, which can be configured as an ultrasound, laser or particularly inexpensive as an infrared sensor. In this way, it is easily possible to check whether an opening in the fire alarm is permeable or clogged or covered.
  • the inserted sensor is preferably arranged such that the space is detected from the opening in the fire alarm to a fire detection sensor inside the fire alarm.
  • a fire detection sensors are working in particular according to the scattered light principle smoke detection sensors.
  • a suitable distance or light sensor for checking the openings can, for example, be integrated into or adjacent to the fire detection sensor and aligned directly with the opening in the housing of the fire alarm to be checked be. In this way, the space between the opening and the actual fire detection sensor is detected easily and reliably.
  • the senor may also be arranged such that the space is detected in front of the opening outside of the fire alarm. This makes sense to determine whether the fire alarm is delivered, for example, by immediately before the opening of the fire alarm furniture arranged or shielded so that the functionality of the smoke alarm is limited.
  • a minimum distance of an object detected in the region of the opening can be predetermined.
  • the sensor is arranged in such a way that its active sensor surface acts outwards through the opening to be detected.
  • the sensor may be arranged in the extension of a straight line extending substantially perpendicular to the opening line in the housing.
  • a reference sensor for measuring the ambient light of the fire alarm.
  • This can preferably be attached directly to the outside of the housing to be checked opening of the fire alarm on the housing or integrated into the housing wall.
  • the ratio of the light intensities of the reference sensor and the sensor for checking the permeability of the opening can be closed particularly reliably on the permeability of the opening.
  • the use of such a reference sensor also prevents false alarms in the event that the test measurement is made at night or in a darkened room.
  • the self-checking device may also be expedient for the self-checking device according to the invention to have a sensor-active mirror and / or a sensor-active diaphragm.
  • a sensor-active mirror and / or a sensor-active diaphragm In the case of light sensors this can be a simple optical mirror and a pinhole act.
  • other detection mechanisms for example ultrasound, infrared or the like, corresponding suitable deflection systems and diaphragms can be used.
  • the fire alarm can have a arranged at an opening of the housing of the fire alarm grille, which relative to the housing the fire alarm is movable.
  • constructions of permanently installed grids are usually provided on the openings, which usually serve as smoke inlet openings, which serve as protection against the penetration of foreign bodies and larger insects. According to the invention it is now proposed to install this grid, in particular within the housing in front of the openings and to move the housing and the grid relative to each other by means of a motor, a spring preload or other mechanical or electrical actuator.
  • a round trained fire alarm is provided with a trained at least as a pitch circle grid, which preferably on the inside of the wall of the housing of the fire alarm is arranged rotatable.
  • the round grid and the round trained fire alarm or its housing are preferably arranged concentrically.
  • a portion of the grid is in each case in front of the one or more openings of the fire alarm and can be rotated slightly further in case of pollution and / or at regular intervals, for example once a month or once a year, so that in each case a fresh, not polluted Grid section in front of the or the openings is located.
  • the opening angle of the opening in the housing of the fire alarm correspond to order a completely new grid area in front of the openings.
  • the grid and the housing are regularly moved against each other at shorter intervals, it may also be sufficient to provide the relative displacement between the grid and the housing opening such that only a part of the opening is covered by a new grid. In this case, the reliability of the fire alarm is also guaranteed, since at least this new grid area should not be more polluted.
  • a special mechanical, chemical, thermal, electrostatic and / or pneumatic, operated with compressed air cleaning device may be provided on the grid, which causes a cleaning of the grid in particular in a relative movement of the housing and fire alarm.
  • the cleaning device may consist of brushes preferably arranged on both sides of the grid, which brushes over the grid surface when the grid moves relative to the housing, thereby ridding it of impurities.
  • the brushes may also have an electrostatic effect to rid the grid particularly reliable even of small dust.
  • the grid and / or housing parts independently carried out a cleaning of the grid and / or the smoke inlet opening.
  • provided cleaning facilities can work with compressed air, chemical and / or thermal processes or the like to perform a cleaning of the grid or the smoke inlet openings, wherein for blowing through the openings of the fire alarm especially a directed from the inside out compressed air jet suitable.

  • This sensor can be an optionally optically and / or acoustically scannable sensor which may also be identical to the sensor for testing the permeability of an opening of the fire alarm.
  • the sensor has an optical waveguide, which is arranged on a wall of the housing inside and / or outside, preferably circulating on the housing wall.
  • the optical waveguide can be mounted directly on the outer wall of the fire alarm and be performed in one or more turns to the housing outer dimensions.
  • a light transmitter can feed a defined amount of light into the light guide, which is registered by a sensor after passing through the light guide. If the housing is damaged, and thus of the light conductor arranged in particular on the outside of the housing, the light intensity registered by the sensor changes. This is an indication of external damage to the fire alarm.

Alternatively or additionally, may be provided as sensors disassembly contacts, for example in the form of mechanical key switch and / or with position change sensors, for example in the form of mercury switches or magnetic switches. According to the invention, the disassembly detection can also be set up in such a way that an alarm is triggered in the event of a detected dismantling of the fire alarm. This ensures that the fire alarm is not unauthorized dismantled from the ceiling and re-attached in unsuitable locations.
  • the fire alarm can also be equipped with other sensors.
  • This can be, for example, integrated into the housing temperature and / or humidity sensors that are used for indoor climate monitoring and, for example, can work together with a higher-level home control for temperature control and / or heating costs.
