The Aiphone LE-D and LE-DA are door stations designed to integrate seamlessly with Aiphone LEF Intercom System Models, including LEF-3, LEF-5/5W, LEF-10/10W, LEF-10S/10SW, LEF-3B, LEF-5B, and LEF-10SB. These door stations facilitate communication between an outdoor entry point and an indoor master station, enhancing security and convenience for homes, businesses, and industrial settings.
The primary function of these door stations is to enable hands-free communication with visitors at the door. When a visitor arrives, they simply press the CALL button on the LE-D or LE-DA unit. This action sends a call tone to the master station(s) inside, alerting the occupant to the visitor's presence. Once the master station replies, communication becomes hands-free from the door station's perspective, allowing the visitor to speak without needing to hold or operate the unit further. The occupant at the master station controls the conversation using a press-to-talk operation, ensuring clear and controlled communication. This hands-free capability is particularly useful for visitors who may have their hands full or for situations where quick and easy interaction is desired.
Installation of the LE-D and LE-DA units varies slightly based on their design. The LE-D model, which features a plastic cover and is surface-mounted, is designed for straightforward attachment to a SINGLE-GANG BOX using two supplied screws. For direct wall surface mounting, the cable can be routed from either the top or bottom of the back case. If routing the cable through the top, a designated outlet part of the case needs to be removed. This design prioritizes ease of installation for a surface-mounted application.
In contrast, the LE-DA model, characterized by its stainless steel cover and flush-mount design, requires a slightly different installation approach. To install the LE-DA, two screws must first be removed to separate the main unit from the front panel. Once separated, wires are connected to the terminals on the main unit. The main unit is then mounted into a TWO-GANG BOX using the two supplied screws. After the main unit is securely in place and wired, the front panel is reattached, completing the flush-mount installation. This method provides a more integrated and aesthetically pleasing finish, as the unit sits flush with the wall surface.
Wiring configurations for these door stations depend on the specific intercom system setup. For a single-master system, the LE-D or LE-DA units typically require two wires for connection, and a shorting link on the unit should remain attached. This simplified wiring is suitable for basic setups where one master station controls communication with the door station. For more complex intermixed systems, where multiple master and sub-stations might be involved, three wires are typically required, and the shorting link on the door station must be removed. This adaptability in wiring allows the LE-D and LE-DA to be integrated into various Aiphone LEF system configurations, from simple to more elaborate setups. The wiring distance is also a critical consideration, with specific guidelines provided for different wire gauges (AWG) to ensure optimal performance over varying distances. For instance, a 24AWG wire supports distances up to 400 feet (120 meters), while a 20AWG wire can extend up to 1000 feet (300 meters), offering flexibility in placement.
Maintenance of the LE-D and LE-DA door stations is designed to be simple and user-friendly, ensuring longevity and reliable operation. Users are advised to clean the door station with a soft cloth that has been dampened with a neutral household cleanser. This gentle cleaning method helps to remove dirt and grime without damaging the unit's finish or internal components. It is crucial to avoid using harsh chemicals such as lacquer thinner or benzine, as these can cause discoloration or damage to the unit's materials. Furthermore, users should take precautions to prevent water from splashing onto the door station, for example, by avoiding direct hosing. While the units are designed for outdoor use, excessive water exposure from sources like a hose could potentially compromise their integrity.
Safety precautions are paramount during installation and operation. It is strictly prohibited to connect any terminal on the door station or any other unit to AC power lines. This is a critical safety measure to prevent electrical hazards and damage to the equipment. When replacing an existing bell or chime with an Aiphone door station, it is essential to first disconnect the wires from the present transformer to avoid any electrical conflicts or short circuits. Adhering to these installation and maintenance guidelines ensures the safe and efficient operation of the LE-D and LE-DA door stations, providing a reliable communication link for years to come.
The operational sequence for the LE-D and LE-DA is straightforward. When a visitor presses the CALL button, a call tone is sent to the master station(s). The master station will then ring, indicating an incoming call from the door station. Once the master station replies, the communication becomes hands-free from the door station's side, allowing for a natural conversation. If multiple master stations are present in a system, momentarily depressing the CALL button will signal all master stations. After any master station replies, the communication from the door station remains hands-free. This simple and intuitive operation makes the LE-D and LE-DA accessible for all users, enhancing the overall visitor management experience.
