PREINSTALLATION AND OPERATION TIPS AND PRECAUSTIONS

Installation;

Never connect any terminals on the units to an AC power line.
When mounting the MFH-UIMFH-UB units in place of existing bell or chime, be sure to disconnect all wires from the present transformer.
Do not open the front cover ofMFH-U/MFH-UB units, without first unplugging the power supply from the AC outlet. The high voltage is loaded on the monitor unit inside.
Do not drop or apply any undue shock to the unit which may damage the picture tube.
Avoid running the connecting wires through doors, windows or in areas that may cause pinching or disconnect.
The MFH-U/MFH-UB units must be installed in as dry and dust-free an environment as possible.
Installation location requirements;
Do not install MFH-U/MFH-UB video monitors in a place where they are directly exposed to; direct sunlight, water, air conditioner, heater, chemicals, frost, iron dust, vapor, etc.
Determine the installation height so that the center of the MFH-U/MFH-UB video monitors will be at the convenient eye level: adults’ average height minus 100 mm (4″).
Maintenance;
Clean your MFH-U/UB equipment with a soft cloth dampened with neutral household cleaner. Never use lacquer thinner, benzine, etc.

INSTALLATION

IE/MFH-U surface-mounting to MBW-A back box;”
SEE ET Se EET Cut a hole 95 mm (3-3/4) high by 215 mm (8-1/2) wide and 40 mm (1-9/16”) deep into the wall. Position the MBW-A box in the wall. with the V-cut in the upper position, so that line A crosses vertically with the fluor. To mount the MFH-U, remove the tup screw in the case. and separate [ront case from the chassis, pushing the bottom, right of front case upward, then the lett side of the case to the right. and removing the connector. Auch the chassis to MBW-A and reattach the front case. To mount IE intercom, attach mounting bracket to MBW-A and mount the unit onto the bracket.
LEF/MFH-U surface-mounting (on gang boxes); When mounting LEF master & MFH-U video monitor side by side, be sure to focate MFH-U to the teft of LEF master. keeping a space of 3 to 5 cm (1-3/16″ to 2″) for brightness and contrast adjustment.
First, separate each chassis from front case.
Mount the chassis with the supplied screws.
After wiring, reattach connectors and front case to chassis.
LEF-B/MFH-UB semi-flush mounting to wall;
To mount LEF-5B/10SB and MFH-UB units.
culand open a hole of H: 206 x W: 306 (mm) (H: 8-1/8″ x W: 12-1/16°), keeping a space of 3 to S cm (1-3/16* to 2”) on cach side. Before installation, join together both LEF-
B and MFH-UB chassis by attaching a Junction hardware with 3 screws (supplied).
Auach two chassises with 4 wood screws (supplied).
After wiring, remount front cases to each chassis.

WIRING DIAGRAMS

IE-2AD(U) SYSTEM w/VIDEO MONITORING CAPABILITY;
The MFW-CZ camera (No. 3) must correspond each with video input terminals IT] (for coaxial cable) and B3 (for video signal input) on MFW-P3.
Connect coaxial cable from MF-D thru MFW-P3 to terminal A on MFH-U.
In a system with more than one video monitor, remove impedance-matching plug on all video monitors, except on the farthest monitor.

IE-2AD(U) can accept max. 2 video door stations, one each for IE-1AD(U) and IE-lGD(U).

(2) LEF VIDEO SYSTEM WITH MONITORING CAPABILITY;

From each MF-DL, connect to either terminal DA, DB or DC on BGR-1 OA all call/BGM adaptor. By this connection, door station call-in can be signalled by chime tone at all the connected master stations.
