Description

Technical Field

[0001] This utility model relates to the field of intelligent access control and fire protection linkage technology, specifically to an intelligent access control and fire protection linkage device. Background Technology

[0002] In the event of an emergency such as a fire, the fire protection system will send a signal. Upon receiving this signal, the intelligent access control fire linkage device will immediately and automatically unlock the access control system to allow for rapid evacuation. Simultaneously, this device can also work in conjunction with other fire protection equipment such as fire alarm systems and fire broadcast systems to ensure timely and effective protection of people's lives and property in emergency situations.

[0003] Chinese Patent 202322685931.7 discloses a fire-fighting linkage device for an access control system, comprising a housing, a sleeve, an access control fire-fighting linkage control component, a dustproof and heat dissipation device, and a wiring mechanism. The sleeve is disposed on the side wall of the housing, the access control fire-fighting linkage control component is disposed inside the housing, the dustproof and heat dissipation device is disposed on the side wall of the housing, and the wiring mechanism is disposed inside the housing. This utility model belongs to the field of access control system fire-fighting linkage technology, specifically referring to an access control system fire-fighting linkage device that can provide timely heat dissipation and dust prevention for the linkage control component inside the housing, while also maintaining good wiring connection with the linkage control component.

[0004] The aforementioned access control system fire alarm linkage device utilizes a fan to dissipate heat from the internal components of the linkage device housing. However, in the absence of a fire, the intelligent access control fire alarm linkage device typically consists of electronic control modules, sensors, and communication modules. These components have relatively low power consumption and generate limited heat during normal operation, usually not producing a large amount of heat. In the event of a fire, the external temperature becomes excessively high, and this heat is drawn into the linkage device. Under high temperatures, this may damage the linkage device, affecting the opening and closing of the intelligent access control system. Furthermore, due to the fan design, this linkage device must protrude from the wall or door panel during installation, making it susceptible to scratches and collisions, which can easily damage its internal electronic components, affecting the accuracy of its intelligent linkage and leading to safety hazards.

[0005] To address the aforementioned issues, an intelligent access control and fire protection linkage device is proposed. Utility Model Content
