There are many types of fire alarm signals, such as dry contact signals, RS485 signals, and AC / DC voltage signals. Different types of signals are used in different situations. However, existing communication modules only have a single signal interface, which cannot meet various usage requirements. They are inconvenient to use, and multiple communication modules are not only bulky and occupy a lot of space, but also expensive. Utility Model Content

[0005] This utility model integrates multiple signal interfaces and can be adapted to various commonly used communication methods on the market: dry contact signals, AC / DC voltage signals and RS485 signals. Therefore, only one communication module of this utility model is needed to meet various usage requirements and adapt to different occasions. It is convenient to use and can effectively reduce the size of the module, reduce the space occupied, and save costs.

[0006] The communication module of this utility model operates at AC220V, and the voltage interface is an AC / DC220V voltage interface. The voltage of the AC / DC220V voltage interface is taken from the ordinary lighting distribution box. When the ordinary lighting voltage is less than 110V, the microcontroller determines that the mains power is cut off and sends an emergency command to the emergency lighting centralized power supply main control unit to execute the fire linkage action.

[0007] The passive dry contact interface described in this invention takes its signal from a Fire Alarm System (FAS), which is an automatic fire-fighting facility capable of early fire detection, alarm, sending control signals to various fire-fighting equipment, and receiving feedback signals from the equipment. When the microcontroller receives the dry contact signal transmitted by the FAS, it sends an emergency command to the emergency lighting centralized power supply main control unit to execute fire-fighting linkage actions.

[0008] When the microcontroller of this invention receives a pre-defined RS485 message through the RS485 interface, it sends an emergency command to the emergency lighting centralized power supply main control unit to execute fire-fighting linkage actions.

[0009] The microcontroller described in this utility model is an STC8G1K08 microcontroller.

[0010] The microcontroller described in this invention draws power from the incoming line of the centralized power supply for emergency lighting.

[0011] The communication module described in this invention operates at a voltage of DC36V.

[0012] Compared with the prior art, the present invention has the following significant advantages:

[0013] This utility model integrates multiple signal interfaces and can be adapted to various commonly used communication methods on the market: dry contact signals, AC / DC voltage signals and RS485 signals. Therefore, only one communication module of this utility model is needed to meet various usage requirements and adapt to different occasions. It is convenient to use and can effectively reduce the size of the module, reduce the space occupied, and save costs. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] Figure 1 This is a schematic diagram of the composition structure of this utility model. Detailed Implementation

[0016] like Figure 1 As shown, this utility model discloses a multi-fire alarm linkage communication module for a centralized emergency lighting power supply. It includes a housing, within which is housed a microcontroller (STC8G1K08) for processing fire alarm linkage signals. The microcontroller draws power from the input line of the centralized emergency lighting power supply. The housing has a voltage interface, a passive dry contact interface, and an RS485 interface. The microcontroller is connected to these interfaces and is connected to the main control unit of the centralized emergency lighting power supply via the RS485 interface.

[0017] In this embodiment, the operating voltage of this communication module is AC220V, and the voltage interface is AC / DC220V voltage interface. The voltage of the AC / DC220V voltage interface is taken from the ordinary lighting distribution box. When the ordinary lighting voltage is less than 110V, the microcontroller determines that the mains power is cut off and sends an emergency command to the emergency lighting centralized power supply main control unit to execute the fire linkage action.

[0018] The passive dry contact interface takes the signal from the fire alarm system (FAS). When the microcontroller receives the dry contact signal transmitted by the FAS, it sends an emergency command to the emergency lighting centralized power supply main control unit to execute the fire linkage action.

[0019] There are at least two RS485 interfaces. When the microcontroller receives a pre-arranged RS485 message (sent by other devices, such as FAS) through one of the RS485 interfaces, it sends an emergency command to the emergency lighting centralized power supply main control unit through the other RS485 interface to execute the fire linkage action.

[0020] Therefore, this utility model only requires one communication module to meet various usage needs and adapt to different occasions. It is easy to use and can effectively reduce the size of the module, reduce the space occupied, and save costs.

[0021] In other embodiments, the operating voltage of this communication module is DC36V.
