PANASONIC VL-MWD272 (01) PDF Document

To ensure safety and prevent fire, electric shock, or short circuits during the installation of the PANASONIC VL-MWD272, follow these guidelines:

1. Leave installation work to the dealer. Installation requires specific techniques and experience. Failure to observe this may cause fire, electric shock, injury, or damage to the product.

2. Electrical connection work should be performed by certified personnel only. Certification is required for performing electrical connection work.

3. Do not attempt to disassemble or modify this product. Contact an authorized service center for repairs.

4. Never install wiring during a lightning storm.

5. Do not connect non-specified devices.

6. When opening holes in walls for installation or wiring, or when securing the power cable, make sure you do not damage existing wiring and ductwork.

7. Do not make any wiring connections when the power supply is turned on.

8. Do not perform any actions that may damage the power cable, such as fabricating, twisting, stretching, bundling, forcibly bending, damaging, altering, exposing to heat sources, or placing heavy objects on it.

9. If existing chime wires are used, they may contain AC voltage. Contact an authorized service center.

Do not install the PANASONIC VL-MWD272 in the following places:

– Places where the monitor may be splashed with water or chemicals.

– Places where there is a high concentration of dust or high humidity.

– Places where vibration or any other kind of impact occurs.

– Places where echoing is frequent.

– Places near a high concentration of dust, hydrogen sulphide, ammonia, sulphur, or noxious fumes.

– Inside a wall.

– On a wall that is deeply recessed.

To avoid malfunction or communication disturbances with the PANASONIC VL-MWD272, adhere to the following precautions:

– Install the main monitor away from electronic appliances such as TVs, radios, personal computers, air conditioners, boiler control panels with intercom, home security equipment, wireless devices, or digital cordless phones.

– Do not install the monitor in places where it will be affected by extremely high-frequency radio waves, such as near broadcasting antennas, as this may cause the display to flicker or noise to occur.

– Leave at least 20 cm of space above, below, and to the left and right sides of the main monitor.

– Be sure to install the main monitor more than 5 m away from the doorphone.

– In areas surrounded by a high electrical field, disturbances may occur in the monitor image or sound.

The following accessories are included for the installation of the PANASONIC VL-MWD272:

– Mounting bracket x 1

– Screws (4 mm x 16 mm) x 2

The wire type used must be a single-pair cable with an outer sheath (jacket) and a solid copper conductor. The maximum lengths depend on the diameter of the wire used:

Note: When an extension monitor is used, the total wiring length from the doorphone to the main monitor and then to the extension monitor must be within about 100 m.

When using an electric lock with the PANASONIC VL-MWD272, select a device that meets the following guidelines for the electric lock connection terminals (S1/S2, S3/S4):

– Use an N/O (Normally Open) dry closure contact.

– The voltage and current must be 30 V AC (1 A) / 24 V DC (1 A) or lower.

For connection devices for option input (A contact) terminals (IN1/IN2/IN3/IN4) on the PANASONIC VL-MWD272, ensure the device meets these criteria:

– Input method: No-voltage contact.

– Open-circuit voltage between terminals: DC 7 V or less.

– Detection definite time: 0.1 second or more.

– Short-circuit between terminals: 5 mA or less.

– Resistance value: Make is 500 ohms or less; Break is 15 kilo-ohms or more.

Follow these steps to position the PANASONIC VL-MWD272 correctly:

1. Place the monitor in a location where your eyes are at the same height as the center of the display.

2. Leave at least 20 cm of space above, below, and to the left and right sides of the monitor. This prevents malfunction, sound cutting out, and ensures the reset button on the bottom of the unit is accessible.

3. For the mounting bracket, ensure it is installed on a vertical flat wall. The hole in the wall should be approximately 60 mm wide and 50 mm high, with a vertical distance of 83.5 mm between the mounting screw holes.

To make wiring connections to the PANASONIC VL-MWD272, follow these steps:

1. Prepare the wires from the doorphone or other devices by stripping the insulation to expose 9 mm of bare wire at the tip.

2. While pressing on the terminal button with a pointed object such as a screwdriver, insert the bare wire into the terminal connector.

3. Release the button to secure the wire. To disconnect a wire, press the button and pull the wire out.

4. Important: Do not connect the power cable during this process.

Once the bracket is secured and wires are connected, mount the PANASONIC VL-MWD272 as follows:

1. Line up the tab on the bottom of the mounting bracket with the groove on the bottom of the main monitor.

2. Line up the tab on the top of the bracket with the groove on the top of the main monitor.

3. Push the main monitor down firmly until it is secure against the bracket.

The PANASONIC VL-MWD272 features several terminals for different connections:

– D1, D2, D3, D4: Terminals for connecting Doorphone 1 and Doorphone 2.

– MI-1, MI-2: Terminals for connecting Extension Monitors.

– MO-1 through MO-6: Output terminals for Extension Monitors.

– IN1, IN2: Option input terminals for devices like emergency terminals.

– IN3, IN4: Option input terminals for devices like doorbells (Note: A doorbell and Doorphone 2 cannot be used together).

– P1, P2: Terminals for PBX connection.

– S1, S2, S3, S4: Terminals for connecting electric locks.

To connect the PANASONIC VL-MWD272 to a VL-V590 lobby station, follow these steps:

1. Connect terminal D1/D2 on the main monitor with terminal D1/D2 on the lobby station.

2. Connect terminal S1/S2 on the main monitor with terminal S1/S2 on the lobby station.

3. After connecting, you must change the [Lobby connection] setting to [Connected devices] using the main monitor interface as described in the Operating Instructions.
