Aiphone MK-1MD/A - Manual (Page 3)

WIRING ----------------------------------------------------
■ Cable requirements
• Use a parallel conductor cable.
Coaxial cable should not be used.
• When existing chime wires are used, it is possible that the wires
may contain AC voltage current. Locate and remove the bell
transformer before actually connecting MK-DS(/A).
• Extra pair(s) in the installed cable can affect image quality, and
must be terminated with a 120 ohm resistor at each end at both
MK-DS(/A) and MK-1 MD(/A). Otherwise, double up the wires
onto each terminal.
I Installation location
MK-DS(/A)
MK-DS(/A) employs CCD camera and the performance can be affected by
bright direct light, such as strong sunlight, gate light, or street or porch
light which comes directly into the camera lens.
MK-1MD(/A)
Mount the video monitor so that the center of the monitor screen comes to
the eye level of the user.
I When camera height is too low
MK-DS(/A) is equipped with a camera-angle adjuster on the back of the
unit. Pull the lever down to adjust the camera angle upward by 14°.

I When installing a second station
MK-1MD(/A) may have a sub station, either the same MK-1MD(/A)
monitor or MK-1SD(/A) handset. Locate the second station within
permitted distance of 100m, 330' from the camera. Wire second inside
station directly to first inside station.
• Video-impedance matching (on SW1): In dual monitor system only,
change initial A setting to B (HIGH) position on MK-1 MD(/A) main-
monitor.
I Call extension
To hear the chime in a remote location, install an IER-2 speaker with 2
wires(NP) from any inside station. One IER-2 per station.

I Door strike
MK-1 MD(/A) monitor provides a dry closure contact for door strike. Use
Aiphone's EL-9S, AC 12V, 0.35A, powered by AC transformer PT-1210N
in USA, or a strike appropriate for the door.
