[0012] The present invention will be further described below in conjunction with the accompanying drawings and embodiments: Figure 1 It is a schematic diagram of the fire alarm device outside the fire-fighting elevator floor door of the present invention. DETAILED DESCRIPTION
[0013] like Figure 1 As shown, a fire alarm device outside a fire-fighting elevator floor door proposed by the present invention includes the following components.
[0014] The switching power supply inputs AC220V alternating current and outputs DC24V direct current voltage to supply power to various components. The switching power supply inputs AC220V alternating current and is connected in series with a power supply switch QF.
[0015] Control main board, receive fire signal through 301 and X5 terminals; The function board is connected to the control main board, receives the control signal from the control main board, and then controls the fire alarms A1, A2, A3...An, and the fire lights L1, L2, L3...Ln; The control contactor includes a coil KM and a normally open contact KM1 and a normally open contact KM2. The coil KM is connected to the function board to control power on. One end of the coil KM of the control contactor is connected to the 24V output terminal of the switching power supply, and the other end is connected to the output control terminal D1 of the function board. The function board is also provided with a data negative signal terminal DM, which is connected to the COM negative terminal of the switching power supply.
[0016] Fire alarms A1, A2, A3...An are all connected and controlled by the normally open contact KM1; fire lights L1, L2, L3...Ln are all connected and controlled by the normally open contact KM2; the fire alarms A1, A2, A3...An are connected in parallel to form an alarm group, one end of the alarm group is connected to the COM negative terminal of the switching power supply, and the other end is connected to the 24V output terminal of the switching power supply through the series normally open contact KM1; the fire lights L1, L2, L3...Ln are connected in parallel to form an alarm group and a fire light group, one end of the fire light group is connected to the COM negative terminal of the switching power supply, and the other end is connected to the 24V output terminal of the switching power supply through the series normally open contact KM2.
[0017] The fire alarms A1, A2, A3...An and the fire lamps L1, L2, L3...Ln are installed outside the door of each elevator floor. One fire alarm and one fire lamp are installed outside the door of each elevator floor.
[0018] The power supply switch QF, the switching power supply, the control main board, the function board and the control contactor are installed in the control cabinet of the elevator.
[0019] In this embodiment, an AC220V power supply switch QF, a function board, a control contactor KM, and a switch power supply are added to the control cabinet; fire alarms A1, A2, A3...An and fire lights L1, L2, L3...Ln are added outside the door of each floor. The AC220V power supply switch QF supplies power to the switch power supply, and the switch power supply outputs DC24V to directly provide power to the control main board and the function board. The switch power supply outputs DC24V to output the voltage of the control contactor coil KM through the function board. The switch power supply outputs DC24V to control the fire alarm A1, A2, A3...An on each floor through the control contactor normally open contact KM1, and the switch power supply outputs DC24V to control the fire lights L1, L2, L3...Ln on each floor through the control contactor normally open contact KM2. When the fire elevator is in normal use, the building fire protection system does not send a signal to the control main board, the function board outputs no signal, and the fire alarm and fire light are in a non-working state.
