The DOORBIRD 429600977 is an IP intercom unit finished in RAL9002 (grey white), designed for building entry and access control applications. The D31TDH designation identifies the specific hardware configuration in the DoorBird product line. As a networked intercom device, it provides two-way audio and video communication between an entry point and interior stations or mobile devices. Installation is typically handled by low-voltage technicians or security system integrators working on residential or light commercial access control projects.
This IP intercom is suited for door station installations where a durable, network-connected entry unit is required. The RAL9002 grey white finish is commonly specified in architectural applications where a neutral, clean appearance is required at the entry point. It is sold as a single unit (each) and falls within the IP intercom product category.
Designed as an OEM-style IP intercom door station unit. Confirm compatibility with your existing network infrastructure and access control system before installation.
Installation should be performed by a qualified low-voltage technician or licensed security integrator familiar with IP network devices and access control systems. Power down or disconnect the network and any associated door strike or lock hardware before servicing. Follow local building codes and manufacturer wiring guidance for Cat5e or Cat6 network connections. Refer to the manufacturer documentation for mounting depth and back-box requirements specific to this unit.
