Important Notices FCC – United States This equipment has been tested and found to comply with the limits for a class A digital device, pursuant to Part 15 of the FCC Rules and Regulations. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
General Information • Prior to beginning the installation of the telephone entry system, we suggest that you become familiar with the instructions, illustrations, and wiring guidelines in this manual. This will help insure that you installation is performed in an efficient and professional manner. •...

SECTION 1 - INSTALLATION Installation of the 1812 Plus Telephone Entry System involves the installation of the hardware and by- pass switch, and the wiring of these components. If used to control a vehicular gate with an automatic gate operator, the...
Mount the By-Pass Switch The 1812’s by-pass switch provides a method to remove the 1812 from the telephone line and reconnect the homeowner’s telephone to the telephone system. The By-Pass switch IS NOT optional – it must be installed as part of the 1812 system. All telephone wiring for the 1812 must pass through the by-pass switch.
Telephone Line Wiring Be sure to observe electrical safety when working with phone lines. Phone lines carry electricity and the ring voltage can deliver a substantial jolt. The best policy is to disconnect the house phone from the phone company Network Interface Device (also known as ‘Demarcation Device’) before working on the wiring.
18 AWG 16 AWG The 1812 Plus system operates on 16.5 VAC. Do not power this device with 24 volt AC power. Use the supplied power transformer, 16 VAC, 20 VA (or U.L. listed equivalent) to power the telephone entry system. Do not power any other devices (electric strikes, magnetic locks, etc.) from this power transformer.

TELEPHONE: Using a touch-tone telephone, many of the programmable features can be programmed from the house or remotely from an off-site location. Programming Information The 1812 PLUS model is not PC programmable. Programming can only be completed by the two methods described below. 2.1.1 Programming from the Keypad Follow the programming instructions as described in each section of this manual.
System Parameter Programming 2.2.1 Phone / Intercom Mode Default setting is 1 (Phone Mode). The 1812 is normally connected in series with a resident’s incoming phone line, which supplies a constant source of DC voltage. When the 1812 is connected in this manner, program the unit for PHONE mode.
2.2.5 Number of Rings to Ring Residence Default setting is 05 (5 Rings). When the CALL button on the 1812 is pushed, this programming sequence sets the number of unanswered rings to the house before the 1812 hangs up. 1. Press * 6 4 and then enter the MASTER CODE. [ * 6 4 _ _ _ _ (beep)] 2.
2.2.8 Tone Open Numbers Default setting for Relay 1 is 9876. Default setting for Relay 2 is 5432. These steps will program the tone open number(s) for both relay 1 and relay 2 (each relay is programmed independently). You will need to enter a four-digit number (see chart below) to set each relay.
2.2.10 Hang Up Tone Default setting is 0. These steps set the number that will hang-up the 1812 after the conversation is completed. The hang up tone is used when a call from the 1812 has been forwarded to an outside number. Once the conversation has ended, the hang up tone number should be pressed;...
2.2.13 Set Call Forwarding Microphone Gain and Speaker Volume Default setting is 71. This adjustment is required only if call forwarding in the 1812 is being used. This step will adjust the microphone gain (the remote handset loudness) and the speaker volume (the 1812 loudness) during call forwarding operation.
Directory Codes 2.3.1 Directory Codes 24 – 50 Dial Phone Number The 1812 has the capability of operating as an auto-dialer system and can store up to 27 phone numbers in its memory. When a visitor enters a directory code on the system keypad, the 1812 will call the phone number programmed under the specific directory code number.
Devices 2.4.1 Simple Access Code Programming This programming sequence programs simple access codes into the system memory. Simple access codes cannot be time zone restricted; they can only be assigned to operate either relay 1 or relay 2 on a 24/7 basis. If you require access codes to be time zone restricted, use the programming sequence in 2.4.2.
2.4.4 Delete All Access Codes This programming sequence deletes all access codes. WARNING: Once started, all access codes will be erased. 1. Press * 7 2 and enter the MASTER CODE. [ * 7 2 _ _ _ _ (beep)] 2.
The calendar chip must be programmed if any of the time related features are going to be used. Note: The clock / calendar chip in the 1812 Plus will keep time for approximately 48 hours if power to the system is lost or removed. If power is off longer than this, the clock / calendar chip will have to be reprogrammed.
2.5.3 Call Forward Phone Number Programming These steps program the call forwarding telephone number into the 1812 memory. Call forwarding can only be used when the 1812 is programmed in phone mode (see 2.2.1). 1. Press * 1 0 and enter the MASTER CODE. [ * 1 0 _ _ _ _ (beep)] 2.
2.5.5 Relay Hold Schedule Default setting in step 3 is 0 (Hold schedules are OFF). This program sequence sets up schedules to automatically activate and deactivate relays 1 and 2 on the control board. Four schedules can be programmed, each of which can be assigned to the desired relay(s).
2.5.6 Time Zones Default setting in step 3 is 0 (Time Zones are OFF). This programming sequence sets up time zones (up to 4) that can be applied to the access codes programmed into the 1812. These time zones can be turned on or off once they have been programmed.
Miscellaneous 2.6.1 Restore Defaults This step will restore the factory set defaults for each of the programming parameters. WARNING: Once started, this sequence will program all values to factory default. 1. Press * 9 0 and enter the MASTER CODE. [ * 9 0 _ _ _ _ (beep)] 2.
SECTION 3 – ADJUSTMENTS Speaker Volume The speaker volume potentiometer is labeled SPEAKER VOL on the control board. The speaker volume should be adjusted for adequate sound. Adjusting the speaker volume too loud could cause feedback from the microphone. 1. Open the front of the telephone entry system and locate the speaker volume adjustment. 2.
SECTION 4 – USER INSTRUCTIONS Resident Operating Instructions 4.1.1 Granting or Denying a Guest Access To place a call from the 1812 to the resident’s house, the guest simply presses the PUSH TO CALL button located on the faceplate. Once the guest has been identified by voice communication, the resident may grant them access by pressing the appropriate tone open number, or they may deny access by simply hanging up.
4.1.3 Dial-Out Phone Numbers To use the dial-out phone number feature, the guest simply presses a two-digit directory code (24-50) on the system keypad. The 1812 will automatically dial out the phone number programmed under the directory code that was entered on the keypad (section 2.3.1). Once the call is answered, the person called may grant access by pressing the programmed tone open number or they can press the hang up number (2.2.10) to disconnect the call without granting access.
Remote Operation 4.2.1 Remote Programming The 1812 can be programmed and operated from a remote location using a touch-tone telephone. Be sure that the ability for the 1812 to answer an incoming call has not been disabled (see 2.2.9). Note: The 1812 master code cannot be programmed remotely – it can only be programmed from the system keypad –...
4.2.3 Relay Activation The 1812 system relays can be activated from the house. Refer to the tone open numbers that where programmed in section 2.2.8 to determine each of the activation numbers. • Momentary Activation (Relay activates for its programmed strike time) •...
SECTION 5 – MAINTENANCE The DoorKing 1812 telephone entry system is essentially a maintenance free device. When the unit is properly installed, it should provide years of trouble free service. Maintenance is limited to updating the access codes and temporary access codes on an as needed basis. The faceplate of the unit should be cleaned on a regular basis to keep contaminants in the air from sticking to the surface and possibly causing pitting.
