What to do if the DoorKing 1812 Classic Intercom System keypad is dead?
First, check for 24 VAC input power, as the keypad might not be receiving any power. Also, verify that the keypad is correctly connected to the circuit board, ensuring that the cable on the plug points down when connected.
What to do if DoorKing 1812 Classic entry code will not work?
Make sure you are pressing # first before entering the code. Also, the entry code might be programmed under a time zone restricted location code and the entry code time zone is enabled. Turn the entry code time zone off, reprogram the time zone boundaries, or reprogram the entry code under a momentary activation location code. Finally, check if the entry code is programmed under a time zone restricted location code and an external time zone input (terminals 6 & 9) is shorted (activated). Remove the external time zone input or reprogram the entry code under a momentary activation location code.
Why won't phones in home ring with DoorKing 1812 Classic Intercom System?
Several factors could be at play. First, ensure the by-pass switch isn't set to by-pass mode. Another reason could be that the 'Do Not Disturb' time zone might be active; either disable it or adjust the time zone settings. Similarly, check if the call forwarding feature or its associated time zone is enabled, and turn them off or modify the time zone boundaries. Also, check for voltage drops in the 24 VAC supply by examining the voltage at terminals 17 & 18. Lastly, disconnect the PHON OUT wires from terminals 4 & 5 and connect a test telephone to these terminals. If the test telephone rings, the issue lies with the phone out wiring; if it doesn't ring, the circuit board may be faulty.
Why is there a buzz or noise on the DoorKing Intercom System line?
Several factors can cause this issue. Check for a short to ground behind the circuit board, pinched wires near the door hinge, or a 24-volt power shorted to a conduit. Also, inspect for a phone line shorted to ground and ensure that the phone wires are twisted. Verify that all wires, including the speaker and keypad, are isolated from ground. Confirm that the cabinet is properly grounded, ensuring the case ground (terminal 3) isn't used as a low voltage common. Check for excessive voltage drop on the 24 VAC power and test the phone line with a telephone test set.
Why does my DoorKing 1812 Classic Intercom System emit a long tone and cancel programming?
This usually happens because you are waiting too long between pushing buttons during programming. It can also occur if you forget to press * first when programming.
How to fix buzz on telephone line with DoorKing 1812 Classic Intercom System?
To resolve this, first remove the PHON IN and PHON OUT wires from the 1812 terminal strip, then connect the PHON IN wires to the PHON OUT wires. If the noise persists, the PHON IN or PHON OUT wires are faulty. Additionally, remove the 24 VAC wires from the terminal strip and check the house phones. If the noise disappears, the 24 VAC wires are likely grounded, and you should replace them. Lastly, inspect the internal wires, switch wires, and battery wires for any pinches or shorts.
