Definitions

  • the invention relates to a manually operable alarm signaling device with a first switching element.
  • Alarm signaling devices are used in security networks and are used to generate an alarm in the event of an emergency, such as an emergency call. of a fire and can be roughly divided into automatic and non-automatic devices. For example, automatic fire detectors detect an emergency based on physical conditions such as Temperature, smoke, etc., while the non-automatic devices must be manually operated to generate an alarm
  • the manually operable alarm reporting devices must operate flawlessly, as any unnecessary false alarm can lead to expensive use by security forces such as police or fire departments.
  • security forces such as police or fire departments.
  • the manually operable alarm devices usually forward the alarm immediately. An unintentional operation of the alarm device thus leads directly to a false alarm.

  • a number of publications are known that correspond to the type of alarm alarm device according to the invention.
  • the alarm signaling device having the features of claim 1 is suitable and / or designed for a particular public or private safety network, such as e.g. a fire alarm system, surveillance system etc.
  • the alarm signaling device has a first and a second switching element which must be operated together to generate an alarm message.
  • the alarm message is generated by the emission of a signal, that is active.
  • a signal applied externally to the alarm signaling device is modified, in particular switched through or blocked. In the latter case, the alarm message from an external monitoring station "polled", that is fetched.
  • the joint operation of the two switching elements causes them to be in an activated switching position at the same time.
  • the alarm reporting device is designed such that the generation of the alarm message only and / or exclusively takes place when the switching elements are or are operated simultaneously.
  • False alarms which may be caused by accidental operation of the alarm signaling devices are reduced by the known mechanical protection devices.
  • other causes of false alarms are, for example, in the corrosion of switching contacts and a resulting opening or closing of the switching contacts or in a change in the switching position by brief shocks or by contact bounce. These causes can occur independently of mechanical protection of the alarm signaling device.
  • the alarm signaling device is preferably designed as a push-button or spring button detector and / or as a manual call point, in particular according to DIN 14 675 and / or EN 54-11.

  • the switching positions are preferably detected indirectly by the measurement of a flowing current and / or an applied voltage and / or an applied potential.
  • the evaluation device is designed to generate the alarm message and / or a maintenance message based on an evaluation of the switch positions.
  • a preferred Ausretelogik is that jointly activated and / or actuated switching elements an alarm message and only one activated and one non-activated switching element a maintenance message and / or a warning that the alarm device may have a defect is generated.
  • the evaluation device and / or logic is designed as an analog circuit or as programming on a computer or as a combination of analog circuit and programming on a computer. In particular, the realization as an integrated circuit (IC) on a chip is also possible.
  • the evaluation device is designed in terms of programming and / or circuitry, so that an alarm message is generated only if both switching elements are in a defined time window, e.g. be operated for up to 3 seconds, preferably up to 2 seconds, in particular up to 1 second.

  • a monitoring unit is provided which is designed to monitor a monitoring current conducted by the switching elements, in particular by the normally closed contacts and / or normally open contacts, in order to monitor the contacting of the normally closed and / or normally open contacts.
  • the monitoring unit is preferably designed to generate a fault and / or maintenance message at a below a predetermined rest value and thus too low or missing monitoring current. For example, a message is generated as soon as the monitoring current is in particular suddenly reduced by more than 50% compared to the quiescent value.
  • the monitoring unit is preferably as part of the evaluation device and / or as part of an external, e.g. central monitoring device and / or implemented as a separate module.
  • a pulsed monitoring current is used as the monitoring current, for the monitoring of which the monitoring unit is designed.
  • higher current values have a positive cleaning effect at e.g. corroded contacts.
  • the monitoring unit has a quiescent value tracking, wherein the monitoring unit to a slow, creeping and / or small change in the monitoring current does not respond and / or by tracking the rest value and a sudden, sudden and / or significant change in the monitoring current leads to the output of a fault and / or maintenance message.
  • a quiescent value tracking wherein the monitoring unit to a slow, creeping and / or small change in the monitoring current does not respond and / or by tracking the rest value and a sudden, sudden and / or significant change in the monitoring current leads to the output of a fault and / or maintenance message.
  • smaller changes than, for example, 50%, in particular 40% or 30%, of the monitoring current are ignored and / or contribute only to a tracking of the quiescent value.
  • the current value of the monitoring current is preferably set as the tracked quiescent value.
  • a fixed threshold and / or limit value is provided for the quiescent value which must not be undershot during the tracking of the quiescent value. If the threshold and / or limit value are undershot by the current monitoring current and / or by the quiescent value, the fault or maintenance message is generated by the monitoring unit.
  • alarm signaling device switching elements and / or evaluation and / or monitoring unit are arranged in a common housing.
