Associated model number: DTKP

Description: The Delta-3 DTKP Keypad is one of Linear’s Series of wireless radio controls designed for use with automatic garage door and gate operators. The Delta-3 radio format provides 256 different codes. In operation, the user enters their unique code on the unit’s keypad and presses the START/STOP button to activate the door operator. For up to 30 seconds after the last activation, the DTKP can be re-triggered by simply pressing the START/STOP button again. This allows the user to re-enter their code. The DTKP has built-in keypad lighting for use at night or in dark areas. By pressing the START/STOP button first, before entering their new code (or pressing START/STOP twice at any time), the user can light up the keypad. The clear silicone keys are backlit with a pleasing green glow. Standard digital receivers are programmed by setting an 8-position dipswitch in the receiver. The DTKP will match the receiver’s code when the correct number keys are pressed before the START/STOP key. The correct code for the DTKP matches the “ON” positions of the receiver. The code must be entered in the descending order. Keys 0 and 9 are not used on the DTKP. A keypad lockout timer will disable the keypad after 3 code entry attempts. The keypad must remain idle for 30 seconds before new attempts can be made.

STEP 1: Check receiver’s code. Locate the coding dipswitch on the receiver. On some receivers (Model DR) the switch is hidden when the receiver is mounted on the door operator. Loosen the three terminal screws to remove the receiver and examine the coding switch. From 8 to 1, write down the numbers of all the “ON” switch positions.

STEP 2: Verify receiver installation. Be sure the receiver is reconnected (if removed) to the garage door operator as described in the receiver’s installation instructions.

STEP 3: Test Receiver. Be sure door area is clear. Try the keypad code. Enter a digit for each receiver switch “ON” position in descending order. The operator should activate when the START/STOP button is pressed after entering the valid keypad code.

STEP 4: Mount Keypad. Use the two screws and screw anchors provided to mount the keypad to the wall. Be sure the keypad is at least five feet above the ground. After mounting the keypad, cover the screw heads using the two plugs supplied.

INFO 1A: Opening battery compartment. The DTKP battery should last up to 5 years with normal use. To remove the battery door retaining screws and slide the battery door off.

INFO 1B: Replacing battery. Remove the low battery and replace it with a fresh 9-volt alkaline or lithium battery. Replace the battery door and retaining screws.

Linear radio controls provide a reliable communications link and fill an important need in portable wireless signaling. However, there are some limitations, which must be observed.

·          For U.S. installations only: The radios are required to comply with FCC Rules and Regulations as Part 15 devices. As such, they have limited transmitter power and therefore limited range.

·          A receiver cannot respond to more than one transmitted signal at a time and may be blocked by radio signals that occur on or near their operating frequencies, regardless of code settings.

·          Changes or modifications to the device may void FCC compliance.

·          Infrequently used radio links should be tested regularly to protect against undetected interference of fault.

A general knowledge of radio and it vagaries should be gained prior to acting as a wholesale distributor or dealer, and these facts should be communicated to the ultimate users.
