What to do if my DKS Intercom System keypad is dead?
If the keypad is dead, there might be no power. Check for 24 VAC input power. Also, ensure the keypad is properly connected to the circuit board, making sure the cable on the plug points down when connected.
How to fix buzz or noise on the DKS Intercom System line?
To address a buzz or noise on the line, try the following: * Check for a short to ground behind the circuit board. * Check for pinched wires near the door hinge. * Check for 24-volt power shorted to a conduit. * Check for a phone line shorted to ground. * Make sure the phone wires are twisted. * Ensure all wires, including the speaker and keypad, are isolated from ground. * Verify the cabinet is properly grounded, ensuring the case ground (terminal 3) is not used as a low voltage common. * Check for excessive voltage drop on the 24 VAC power. * Check the phone line with a telephone test set.
Why can't I get into programming mode on my DKS Intercom System?
If you're unable to enter programming mode, it could be due to several reasons. You might have entered the wrong master code, so try starting over.

What to do if phones in home will not ring with DKS Intercom System?
If the phones in your home aren't ringing, verify that the by-pass switch is not set to by-pass mode. Also, check if the 'Do Not Disturb' time zone is enabled; if so, turn it off or change the time zone boundaries. Additionally, see if the call forwarding feature or call forwarding time zone is turned on; disable them or adjust the time zone boundaries. Check for voltage drop in the 24 VAC supply at terminals 17 & 18. Finally, disconnect PHON OUT wires from terminals 4 & 5. Connect test telephone to terminals 4 & 5. If test telephone rings, problem is with phone out wiring. If test phone does not ring, circuit board may be at fault.
What to do if the DKS Intercom System emits a long tone and cancels programming?
If the system emits a long tone and cancels programming, it could be that you are waiting too long between pushing buttons. Try to enter the information more quickly. Also, make sure you are pressing * first when programming.
Why does my DKS Intercom System generate a tone when granting access to a visitor, but will not work on regular phone line?
If your system generates a tone when granting access to a visitor but doesn't work on a regular phone line, try switching the wires on the PHON IN terminals.
What to do if phones in home ring, but no communication occurs with DKS Intercom System?
If phones in the home ring, but no communication occurs, check the telephone company demarcation (interface) device placement. The 1812 must be wired so that the C.O. wires exiting the demarcation device are connected to the C.O. terminals on the bypass switch, according to the wiring diagram. Also, disconnect the PHON OUT wires and connect a test telephone to the PHON OUT terminals (4 & 5). If the 1812 cannot communicate with the test phone, PHON IN and PHON OUT wires may be connected backwards. Check wiring and reconnect.
Why won't my DKS Intercom System answer when called from a remote location?
If the system isn't answering when called from a remote location, the auto-answer feature might be turned off. Turn the auto-answer feature on. Alternatively, the number of rings to answer may be programmed too high, so reprogram the number of rings to answer.
Why won't my DKS Intercom System answer when called from the residents phone?
If the system will not answer when called from the resident's phone, you might be using the wrong attention number. Try re-programming the attention number.
What causes a dial tone to be heard on the DKS Intercom System 1812 speaker?
If a dial tone is heard on the 1812 speaker, the system is not wired in series with the resident phone line. Check the PHON IN terminals (1 & 2) and the PHON OUT terminals (4 & 5).
