Definitions

  • the present invention relates to an intrusion detector, with a voltage regulator for the Input voltage, detector electronics and an alarm display.
  • intrusion detectors of this type that is formed, for example, by a light-emitting diode Alarm display arranged parallel to the detector electronics, so that two circuits in the detector are formed.
  • the voltage regulator must supply additional current, which is based on negatively affects the power consumption of the detector.
  • bus detectors are detectors that with two wires are connected directly to a central unit, whereby supply and data transmission done over the same wires.
  • the invention is now intended to provide an intrusion detector which is particularly suitable for bus operation specified, which is characterized by a reduced power consumption. In doing so but the use for bus operation should not be understood as restrictive.
  • the inventive solution to the problem is characterized in that the Alarm display is arranged in series with the detector electronics and is operated with electricity, that the detector electronics need.
  • a second preferred embodiment of the intrusion detector according to the invention is characterized by means of a switch for bridging arranged parallel to the alarm display the alarm display.
  • a third preferred embodiment is characterized in that the switch in normal operating state of the detector is closed and only in the event of an alarm or for test purposes is opened.
  • This switch is preferably from the detector electronics or from a control center actuated.
  • this Intrusion detectors for example, is a common passive infrared detector, such as that from Siemens Building Technologies AG, Cerberus Division and is distributed by Alarmcom AG.
  • Detectors contain a pyro sensor, an infrared mirror or a Fresnel lens arrangement to focus the incident infrared radiation on the pyro sensor and a circuit to evaluate the signals from the pyro sensor.
  • the detector can, for example named bus detector, which is directly connected to a control center with two wires, whereby supply and data transmission take place over the same wires.
  • the detector can, however also wired to the control center in another way or it can be a radio detector or not a control center for so-called stand-alone detectors.
  • the reference numeral 1 denotes the input of the circuit, the reference numeral 2 one Voltage regulator, the reference number 3 the detector electronics and the reference number 4 one Alarm display, which by a light emitting diode (LED) or by an acoustic signal transmitter is formed.
  • At input 1 there is, for example, a voltage of 12 V, that in the voltage regulator 2 is regulated down to 5 V, for example.
  • the voltage regulator 2 can by a single Component formed, but it can also be a voltage stabilization from several Trade components.
  • the heart of the detector electronics 3 is a microprocessor, one Microcontroller, an ASIC or an evaluation unit without a microprocessor, microcontroller or ASIC.
  • the alarm display 4, which is connected in parallel to the detector electronics 3, is in the normal operating state, if no alarm state is detected, switched off.
  • the alarm display 4 is activated by the detector electronics 3 switched on and emits an alarm signal for a few seconds so that the The alarm is not only reported to the control center but is also displayed directly on the detector. always when the alarm indicator 4 is turned on, the voltage regulator 2 needs additional current deliver.
  • the alarm display can be operated with current pulses to reduce power consumption and then does not enter continuously for, for example, 3 seconds Alarm signal, but only three short alarm signals every second. This intermittent However, operation can have a negative impact on detection tests.
  • a frequently performed detection test is the so-called walking test, in which the detector is remotely controlled or by acting on a reed contact arranged inside the detector Magnet is switched into a test mode and one person monitors the detector Crosses space.
  • the alarm display 4 In this walking test, the alarm display 4 must also have an alarm signal as soon as the two criteria alarm and test mode are fulfilled.
  • the alarm display 4 is not arranged parallel to the detector electronics 3, but in series with it, and is between input 1 and the voltage regulator 2.
  • a switch 5 is arranged parallel to the alarm display 4. With switch 5 open the current flows from the input 1 to the voltage regulator 3 through the alarm display 4, when closed Switch 5 is bypassed the alarm display 4 and the current does not flow through this.
  • the switch 5 is controlled by the detector electronics 3 or via the control center. Switch 5 is normally closed and alarm indicator 4 is switched off. Just In the event of an alarm and for a walk test, switch 5 is opened.
  • the Alarm display 4 is formed by a light emitting diode or by an acoustic signal generator his. Although a light-emitting diode to indicate an alarm is already operated with approx. 0.5 to 1 mA the total power consumption of the detector is when using an LED as an alarm display 4 below 1 mA.
