Definitions

  • a preferred application of the invention is in the field of alarm transmission in fire alarm systems.
  • the automatic fire alarm transmission equipment used with which the alarm signal a fire alarm panel or a push button fire detector via a transmission network, such as ISDN, transmitted to a fire station and evaluated there by a receiving device.
  • the transmission device which is located in the area of the object to be protected, even then remain operational if the fire alarm system itself has been affected by a fire and therefore can not give an alarm to the transmission device.
  • a system for detecting a malfunction in which a sensor device for forwarding a signal for a malfunction is coupled to a telecommunication device. Also in this case, the sensor device has an independent of the building energy supply system power supply device in the form of a rechargeable battery.
  • US-A-5278888 discloses a hazard detection system corresponding to the preamble of claim 1.
  • the aim of the present invention is therefore to design a hazard detection system of the type mentioned so that the transmission device is not only completely independent of the supply network of the object to be monitored, but also requires virtually no maintenance.
  • this object is achieved by a hazard detection system according to claim 1.
  • the invention makes use of the fact that the usual communication networks, such as ISDN, offer the possibility for the power supply of connected terminals electrical power up to a predetermined Upper limit, for example 380 mW, to take.
  • a predetermined Upper limit for example 380 mW
  • the transmission device of the danger detection system according to the invention as well as a telephone without its own network connection draws its energy directly from the communication network.
  • this device not only optimally meets the requirements of the fire department regulations regarding the functional integrity of the transmission device in case of fire, but it is also as good as maintenance-free by the elimination of the battery.
  • Another advantage consists in the fact that the expense of a separate power supply including a cable from the 230 V network is saved with the required protection.
  • the circuit of the transmission device must be designed so that the permissible energy extraction from the communication network is not exceeded.
  • this is readily possible with correspondingly miniaturized components.
  • the transmission device including its power supply circuit is arranged in a common housing with a push-button fire alarm, which means an additional saving of space and installation effort.
  • the network termination unit of the communication network with, if the detector housing is adjusted as needed in size.
  • FIG. 1 shows a block diagram of a danger detection system, for example as a fire alarm system with a manually operated detector M1, a transmission device UE, a communication network KN and a reporting center FZ, which is a fire station in the present example.
  • a danger detection system for example as a fire alarm system with a manually operated detector M1, a transmission device UE, a communication network KN and a reporting center FZ, which is a fire station in the present example.
  • the communication network KN which is only indicated here, is provided at its illustrated ends each with a network termination unit NA, which allows the connection of terminals. If the network is, for example, an ISDN network, then the termination takes place in each case with the so-called NTBA device (Network Termination Basic Access).
  • NTBA device Network Termination Basic Access
  • the transmission device UE In the central FZ an alarm recognition device AE is connected to the communication network in this way, while at the other end the transmission device UE according to the invention is connected to the network termination unit NA.
  • the actual transmission circuit preferably a microcontroller MC, is designed so that it evaluates, for example, a message signal m1 from the detector M1 and in the form of an alarm signal AL on the communication network and addressed to the evaluation device AE in the central FZ.
  • control signals MS can also be transmitted from the center FZ via the communication network KN in the transmission device.
  • the transmission device UE further includes a power supply circuit EV, which essentially includes a transformer TR shown schematically. This is on the primary side connected to the network termination unit NA and this takes the supply current I v for the transmission device UE.
  • a power supply circuit EV which essentially includes a transformer TR shown schematically. This is on the primary side connected to the network termination unit NA and this takes the supply current I v for the transmission device UE.
  • the transmission device UE is connected together with its power supply circuit EV via the network termination unit to the communication network CN.
  • the Transmission device provided an interface SS, via which a fire alarm system BMA can be connected to a plurality of detectors.
  • a detector signal m2 of the fire alarm system BMA is thus converted via the interface SS and the microcontroller MC in an alarm signal AL and placed on the communication network CN. If the fire alarm system BMA fails, it is still possible to generate an alarm signal via the detector M1.
  • control signals can also be transmitted from the control center to the signaling system BMA or to its individual detectors.
