• Answer incoming call feature is disabled. Enable answer incoming call feature (2.3.7).
• Number of rings to answer may be programmed too high. Reprogram number of rings to answer.
System will not answer
when called from a remote
location.
• Forgetting to press # first.
• Access code is time zone restricted and the access code time zone is enabled. Disable access code time
zone
(4.8), reprogram time zone boundaries (2.4.4) or reprogram access code for momentary activation
location code (2.6.1).
• Access code is programmed under a time zone restricted location code and external time zone input
(terminals 6 & 9) is shorted (activated). Remove external time zone input or reprogram access code
under a momentary activation location code (2.6.1).
Access code will not work.
• Switch the wires on the PHONE IN terminals.
System generates tone
when granting access to a
visitor, but will not work on
regular phone line.
• Check telephone company demarcation (interface) device placement. 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.
Check the wiring diagram.
• Disconnect the PHONE OUT wires and connect a test telephone to the PHONE OUT terminals (4 & 5).
If the 1812 cannot communicate with the test phone, PHONE IN and PHONE OUT wires may be
connected backwards. Check wiring and reconnect. Phones in home ring, but
no communication
occurs.
• Remove the PHONE IN and PHONE OUT wires from the 1812 terminal strip. Connect the PHONE IN
wires to the PHONE OUT wires. If the noise is still present, bad PHONE IN or PHONE OUT wires.
• Remove 24 VAC wires from the terminal strip. Check house phones. If noise goes away, 24 VAC
wires are probably grounded. Replace wires.
• Check internal wires, switch wires, battery wires for any pinches or shorts. Buzz on telephone line.
Symptom Possible Solution(s)
• 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.
• Check that the phone wires are twisted.
• Check that all wires, speaker, keypad, etc., are isolated from ground.
• Check that the cabinet is properly grounded. Be sure case ground (terminal 3) is not used as a low
voltage
common.

and call forwarding time zone. Change call forwarding time zone boundaries.
• Voltage drop in 24 VAC supply. Check voltage at terminals 17 & 18.
• Disconnect PHONE 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.
Phones in home will not
ring.
• Switch the wires on the PHONE OUT terminals (4 & 5).
• Switch wires on PHONE IN terminals (1 & 2) if using the call forward or preprogrammed dialing out features.

momentary activation location code (2.6.1).
• A hold command was sent to the relay from the homeowner's phone. Deactivate the relay using the
homeowner's phone (Tone open numbers, 4.13). Electric strike locks on or
gate operator holds open.
