  • the detector measures and stores the basic signal, or near-alarms are registered or the hazard signal recorded in each case is saved.
  • the invention is now intended to wirelessly read the data or information mentioned from the detector without tampering with the detector, such as opening of its housing are required.
  • a hazard detector with a communication interface is known from EP-A-0 361 585, which receives the setting data when a corresponding signal from the control module is received of the detector to the control module. The transmission of those recorded by the detector Data is not provided for this hazard detector and the detector also points no light source for alarm display.
  • the hazard detector can, for example, be a passive infrared detector, which evaluates the infrared radiation received from a surveillance area and the Triggering of an alarm signal by the light source preferably formed by an LED displays.
  • the LED is controlled by the detector's microprocessor via a driver that it lights up for a few seconds, for example two, in the event of an alarm. It is also possible, integrate the driver into the microprocessor and the LED directly to the microprocessor to join.
  • the driver or the microprocessor is designed such that that the detector data is in a suitable format, e.g. LED brightness, duration and / or number of pulses and pulse gaps can be sent.
  • a suitable format e.g. LED brightness, duration and / or number of pulses and pulse gaps can be sent.
  • This variant is Particularly inexpensive because there are no additional components or elements on the detector itself requires.
  • the optical transmission of the detector data is absolutely potential-free and influences the detector with regard to electromagnetic compatibility in no way, which leads to the investigation of Problems in the practical use of the detector can be important.
  • the communication interface has a receiver for emitted from an external source Dates on.
  • the invention further relates to an operating module in combination with the hazard detector mentioned.
  • This is designed as a mobile unit and has Means for receiving the sent detector data.

  • the sensor generates a signal when the infrared energy changes Microprocessor for alarm release is processed.
  • the housing of the detector 1 consists of a base 2 and a base on this fixable cover 3, in which the pyro sensor, the infrared mirror and a circuit board 4 are integrated. Because the pyro sensor and the infrared mirror are known and also are not essential to the invention, they are not shown infrared-transparent window 5 is used, through which the infrared radiation from the individual zones of the surveillance area on and from the infrared mirror reaches the pyro sensor.
  • the cover 3 contains one serving to lock it with the base 2 Screw snap closure 6, in the head of which contains a light guide 7 Bore is arranged so that the light guide 7 in the head of the snap lock 6 is fixed and is moved with it when the closure 6 is rotated.

  • the light guide 7 is above one on the circuit board 4 arranged light source 8, which is preferably formed by an LED.
  • the light source 8 is either directly from the microprocessor or controlled by a driver so that it lasts for a few seconds shines. The light from the light source 8 passes through the light guide 7 from the interior of the housing to the outside and becomes visible from the outside.
  • the structure of the detector 1 described is only to be understood as an example. Essential the only thing is that the detector has evaluation electronics and one that is visible from the outside Light source for displaying alarms so that current detector signals for analysis and Verification purposes can be issued.
  • This memory can, for example, in a microprocessor, microcontroller or ASIC integrated, but it can also be formed by a RAM.
  • the detector can form part of a system and connected to a hazard alarm center or it can be installed autonomously and connected to an alarm device.

If the detector 1 is in operation and armed, the signal delivered by the pyro sensor becomes permanent evaluated, with this evaluation in addition to the rather rare event of alarms A large amount of information and data is generated, the further, especially statistical, Evaluation for the creator and / or the operator of the system or the detector can be of considerable interest.
  • detector data Data and information are then stored in detector 1 and are available for further use Evaluation available for what purpose they are sent from the detector to a suitable processing system which have to be transmitted, for example a portable computer, preferably a PC or a laptop.
  • the detector data is transmitted wirelessly, without any special manipulations on the detector, such as opening the detector housing, required are.
  • the reading is preferably carried out as part of service or maintenance work, the portable computer into which the data is read are part of the equipment of the service personnel.

  • the light source 8 is used by the for the purpose of sending out detector data Microprocessor, either directly or via the driver, so modulated in brightness, that the detector data can be transmitted to the outside in a suitable format.
  • a suitable format would be, for example, the duration and / or the number of pulses and / or pulse gaps. Under no circumstances can the detector data be transferred if when the detector is in the monitoring state, but it is also at Not armed detector not automatically and not constantly, but only in a special data transfer mode.
  • the detector In this data transfer mode, the detector is either remotely controlled or brought by hand.
  • the center can, for example, trigger the data transfer mode remotely the telegrams assigned to the two states "night" and "test” send the detectors, which usually do not make sense in this combination, because Tests cannot be carried out at night where the detectors are in surveillance mode are located.
  • the non-remote controlled triggering of the data transfer mode with simple Detectors without remote control inputs can be done, for example, in that the operating state of the detector is switched from the outside with a magnet that opens a reed contact located inside the detector.
  • Jumper is a switch for switching to different modes or operating states of the detector, can be arranged, but the detector is open for switching what would have to be, however, due to the wireless transmission of detector data should be avoided. In any case, it must be ensured that a possible alarm also has priority in data transfer mode, and that the non-remote controlled triggering of the data transfer mode can only be carried out by authorized persons, i.e. the detector is sabotage-proof in this regard.
  • an operating module that can be coupled to the detector 1 9 provided.
  • This has an adapted to the contour of the detector 1 Form and can be fixed in a defined position on detector 1.

  • the housing cover is used for data communication with the microprocessor of the detector removed and replaced by a "service cover" forming the operating module, which has an infrared transmitter and an infrared receiver, so that infrared radiation from the sender of the service cover to the receiver of the detector and from the sender of the detector can reach the recipient of the service cover. It is also possible that way As with the passive infrared detector described, the data between the detector and the control module exchange over a certain distance. In this case, the service cover not form the operating module, but would be the connection between enable the communication interface of the detector and the control module.
  • the tamper switch would trigger an alarm when the housing cover was opened, but this is not a problem because the opening is done by an authorized service person who can turn off the alarm. On the other hand, it is impossible for an unauthorized person tries to communicate with the detector's microprocessor, without the alarm being triggered by the tamper switch.
