Description

Technical Field

[0001] This utility model relates to an alarm device, and more particularly to a fire protection module box. Background Technology

[0002] In existing technology, fire alarm module boxes, also known as fire alarm terminal boxes, are specifically designed for wiring and branching of fire alarm systems, enabling automatic alarm functions in the event of a fire. Traditional fire alarm module boxes are mostly assembled and fixed using screws, which are usually exposed on the casing, resulting in poor aesthetics. Furthermore, during installation, commissioning, and subsequent maintenance, auxiliary tools such as screwdrivers or wrenches are required to open the casing, making disassembly and assembly cumbersome and reducing worker efficiency.
