What building intercom brands are supported by your elevator access control products combined with the elevator building linkage board

Hello, currently our elevator board is combined with the elevator linkage board (FC-ED86), so far, it has been well connected: Anjubao's new DT485, Starlight Building, Guanlin, Jiaweishi, RL Roule, Shikongda, Lilin, Shidean and other brands. If we need to provide new brand access for free, you only need to provide the brand communication protocol. Thank you for your support
