Listed below are the most frequently asked questions for the JO Series. If you are unable to find the information you are looking for please contact our Technical Support team.
For that information you need to call the manufacturer of the door strike or magnetic lock. Aiphone cannot answer that question and cannot provide you with an acceptable alternative.
- If the lock opens: The contacts of the master station may be compromised. Contact Aiphone Technical Support if you suspect the unit needs to be seen for repair.
- If the lock does not open: The lock, it’s power supply, or the wire may be the issue and additional troubleshooting may be needed outside of the Aiphone equipment.
The same test may be done if the RY-18L relay is used by shorting the BROWN and ORANGE wires on the RY-18L.For more information about the RY-18L, click here to view its installation manual.
- Bring the door station to the JO-1MD(or JO-1FD) and connect the A1/A2 terminals on the door station to the A1/A2 connections on the master station. This test will help verify the integrity of the wire, the wiring distance and the hardware.
- Ensure wiring distance between door and master station is within 330′(100m) and is without outside eletrical interference caused by high voltage wires ran in parallel with the intercom wires, or environmental interference such as exposed wire or standing water in a conduit.
- Meter the power supply of the JO-1MD (or JO-1FD), checking for ~18v DC. Also verify that this power supply is not being shared with 3rd party devices, such as a door lock. For more information about the power requirements of the JO Series, click here to view its installation manual.
- Use the “push-to-talk” answering method, by pressing and holding the “talk” button for about 2 seconds when answering an incoming call. Doing this will enable a “walkie talkie” method of communication, where the person at the master station must press the talk button down in order to speak. The person at the door station will not have to press anything to reply, however, they cannot speak when the master station is transmitting audio.
If communication is regained or improved, the environment may be too loud for this series of door station.
