To prevent shorts, be sure to cut unused lead wires at the bottom and insulate the ends.

[1]Video signal output: Video can be output to DVR, etc.

(NTSC, 1 Vp-p/75 Ω ) Wiring distance: 3 m

NOTES: When a video signal is output, the monitor station may produce a buzzing sound depending on the installation environment.

A video signal is only output during calling from a door station to the JK- 1MED/during communication between a door station and the JK-1MED/during monitoring from the JK-1MED (screen playing recorded pictures is not output).

[2]Options output

(AC/DC 24 V, 1.6 A N/O dry closure contact) (Minimum Contact : 100 mV DC, 0.1 mA)

[3] External sensor input settings are required.
