Embodiment Construction

[0024] figure 1 The hazard alarm 1 accommodated in the alarm socket 3 is shown by way of example of a fire alarm. The fire alarm 1 can be removably accommodated in the alarm socket 3 , for example in the sense of a bayonet connection. The fire alarm 1 is fastened by way of example to a ceiling (not shown further) for monitoring a room. The reference numeral 2 shows an alarm line, usually a two-wire line, via which the fire alarm 1 communicates with a hazard warning center (not shown in further detail) in signaling and / or in data technology via an alarm socket 3 . connected. In most cases, the fire alarm 1 is also supplied with power via the alarm line 2 .

[0025] figure 2 An exemplary horn socket 3 is shown with a housed two-terminal network R1 and with four contacts X1, X2, X3, XEA, and figure 2 An associated hazard indicator 1 is shown, which has four mating contacts Y1 , Y2 , Y3 , YEA, in particular for the electrical reading of the two-terminal network R1 according...

Abstract

A detector base (3) is used for releasably receiving a hazard detector (1), for setting two operating modes of hazard detector. The electrical characteristic value of two-terminal resistor (R1) in detector base is read out by an electronic controller (4) of hazard detector. The two-terminal resistor is connected to electrical contact (XEA) that is connected to electrical contact (YEA) of electronic controller. An external optical and / or acoustic alarm generator is connected with hazard detector, for reading the electrical characteristic value of two-terminal resistor. An independent claim is included for hazard detector.

Description

technical field [0001] The invention relates to the use of a two-terminal network arranged in an alarm socket for detachably receiving a hazard alarm, which two-terminal network can be read electrically by an electronic control unit of the hazard alarm . [0002] Furthermore, the present invention also relates to a hazard alarm designed to be detachably accommodated in a structurally matching alarm socket, wherein the hazard alarm is positioned on its side facing the alarm socket. On one side there is a row of first electrical contacts, which contact a second row of opposite contacts in the state of the hazard indicator when it is accommodated in the horn socket. Wherein, the first part is configured to be connected to the alarm line or the alarm line, at least for supplying power to the hazard alarm. Furthermore, wherein the second part is not configured for connection to an alarm line. Furthermore, the hazard alarm has an electronic control unit for controlling the hazard...
