Aiphone KB-DAR-M Video Door Station with Remote Activation Contacts
The Aiphone KB-DAR-M is a tilt-controlled video door station designed for integration with motion detection systems and remote activation devices. This model extends the capabilities of the KB-3MRD video intercom system by allowing any standard motion detector or activation device with a normally open contact to interface directly with the door station. When triggered, the motion detector activates the camera and sounds a chime at inside monitor station(s), alerting occupants to activity at the entrance.
Overview
The KB-DAR-M combines essential video intercom functionality with flexible motion detection integration. The unit mounts directly to a wall or 1-gang electrical box, making it suitable for both retrofit and new installations. Communication is hands-free, allowing two-way voice interaction between the door station and master or sub-monitor handsets within the KB-3MRD system. The tilt-controlled camera and locator LED backlit call button ensure visibility and usability in varying lighting conditions, with LED illumination that automatically activates in low-light environments.
Key Features
- Motion Detector Interface: Accepts normally open contact signals from any standard motion detector or activation device, triggering camera activation and chime notification
- 1/4" CCD Camera: Captures video with a vertical view area of 3'8" to 7'1" and horizontal coverage of 2' at 20" distance
- Tilt-Controlled Camera: Adjustable camera angle for optimal positioning at the entrance
- Hands-Free Communication: Two-way voice intercom with master and sub-monitor stations in the KB-3MRD system
- Automatic LED Illumination: LED lights activate automatically in low-light conditions to ensure visibility
- Locator LED Backlit Call Button: Illuminated button improves usability and visibility
- Fire-Resistant ABS Plastic Housing: Durable material construction rated for operating temperatures from 14°F to 140°F (-10°C to 60°C)
- Surface Mount Design: Mounts directly to wall or standard 1-gang electrical box without requiring special frames
- Extended Communication Distance: Supports 330 feet of cable run using 22 AWG wire, or 650 feet using 18 AWG wire (requires Aiphone #871802 low-capacitance, non-shielded cabling)
Integration & Compatibility
The KB-DAR-M (often searched as KB DAR M) is specifically engineered for integration with Aiphone's KB-3MRD video system and compatible handsets including the KB-3HRD sub-monitor with handset and KB-3SD audio-only sub-handset. The motion detector interface accepts standard normally open contacts, providing flexibility for integrating third-party motion sensors and detection devices. Connection to master and sub-monitor stations utilizes two-conductor, low-capacitance, non-shielded cable, with maximum run distances dependent on wire gauge. The unit does not support IP network integration and operates as a standalone door station within the KB-3MRD analog intercom architecture.
Wiring and Installation
Proper cabling is critical for reliable operation. Use Aiphone #871802 cable for all door station to master station connections. Two-conductor configuration minimizes installation complexity while the low-capacitance specification maintains signal integrity over extended runs. Maximum distances of 330 feet (22 AWG) or 650 feet (18 AWG) ensure flexibility in building layout planning.
The Aiphone KB-DAR-M addresses a specific integration need: connecting motion detection to an existing or new KB-3MRD intercom system without requiring complex relay logic or external control modules. In my experience evaluating door station configurations, the motion detector contact interface eliminates unnecessary intermediary hardware and simplifies commissioning for security integrators.
Technical Highlights:
- Motion Detection Interface: Direct normally open contact acceptance allows rapid integration of passive infrared detectors, door/window sensors, or other contact-closure activation devices without additional controllers
- Camera Specifications: The 1/4" CCD sensor with defined view area (3'8"-7'1" vertical, 2' horizontal at 20") provides clear facial recognition capability at typical entrance distances, suitable for access verification and incident documentation
Deployment Considerations:
- Verify cable run distances before installation; the 330/650-foot limits with specified wire gauge are non-negotiable for signal integrity on analog systems. Plan cable routing and gauge selection during design phase
- The fire-resistant ABS housing and temperature rating (-10°C to 60°C) make this suitable for indoor and protected outdoor environments; verify mounting location exposure before deployment
The KB-DAR-M is a straightforward addition to KB-3MRD systems where motion-triggered video verification is required. Confirm system compatibility with your installed handsets and plan wiring infrastructure early in the project timeline.
