Japanese Quality Expansion Monitor for the JO Series Video Gate Intercoms

Two Gate/Door Buttons 

A lock button on the monitor releases an electric lock on a pedestrian gate or front door. A second button on the monitor can open an automatic driveway gate or garage door.

Chime Volume Adjustment

The chime volume can be adjusted for the space its in or muted in case no-one wants to be disturbed. 

Power Requirements 

No extra Power supply (transformer) is required as the one that comes with the JO Intercom Kit is enough to power two monitors.

The Lock Outputs

The lock outputs from this intercom are on the monitor so an extra two wires are required from the monitor to each gate or door. The outputs maybe wired to activate an electric lock for a pedestrian gate requiring a separate power source to match the electric lock or can be directly connect to a gate or garage door operator. See wiring diagram below and our page on installing intercoms for more information on how this works. 

Wire Type Size verses Distance 

The wire between the Outdoor Camera and Indoor Monitor, between monitors or between the monitor and extension chime should have 2 solid cores (not stranded), should not be a twisted pairs and should have a weather proof polythene sheath. The size of the wire verses distance is:

0.65mm dia. to 50m - 0.8mm to 100m 

The wire between the Power Supply (transformer) and the Monitor should be the same as above but the size verse distances are:

0.65mm dia. to 5m - 0.8mm dai. to 10m.
