- Non-locking (Momentary ): Dial 1 (2/3/4 is the same), relay 1 "Open", relay close after 1 second delay Self-locking: Dial 1, relay 1 "Open", dial 1 again, relay 1 "off", and so on Inter-lock: Dial 1, relay 1 "Open", other relays "Off"; dial 2, relay 2 "Open", other relays "off", and so on "Delay": Dial 1, relay 1 "Open", relay 1 "Close" after a time
- As shown above, by phone remote control relay. You need two phones, one as a receiver (phone_1), the other one as a transmitter (phone_2); mobile phone_1 connected by DTMF audio cable 3.5MM audio controller (the controller to be powered), and then using phone_2 ( may be a fixed telephone) call the phone_1, phone_1 answered, so that two phone call each other; then dial 1/2/3/4 by phone_2 keypad to control four relays.
- As shown above, by phone remote control relay.

- DTMF audio controller must use stable work of DC 12V power supply (recommendations 1A or above the power adapter)
- Remote control the controller by a mobile phone, the receiver must be the phone with 3.5MM audio interface, the transmitter can be a cell phone or landline
- As a receiver of the phone or a computer installed the "DTMF Dial" software must output a sound (not muted), or they will not control relays.
- By default, The AD22B04 4 channel DTMF controller commands are saved in four numbers, ‘1,2, 3, 4.’ but you can also modify appropriately the coding instructions with arbitrary 1-4 four bits (0,1,2,3,4,5,6,7,8,9).
- The controller has two models, "operating mode" and "setting model". The default is "operating mode", but it will be changed into an "setting model" when you press its "key" button.
- Factory settings: If you forget the instructions you set before, you can reset it: Keeping pressing consistently the key button about 10 seconds until you see that the LED lights on again. After that, the product of operations will restore to its default commands, ‘1,2, 3, 4.’.
- The setup processes:
- First, the DTMF controller should work properly, guaranteeing its power supply and audio cable are connected correctly.
- Second, as pressing the key-button, the LED lights off, the product will go into the "setting model".
- Thirdly, begin to input commands with mobile phone or computer.
- Fourthly, when finished the third step, activating the product of key- button or powering it up again.

Its a very good DTMF decoder for putting it on your own tornado siren, it is very good for it.

Easy hookup but unfortunately 2 of the 4 relays were bad. They were getting power verified by a multimeter but did not function.

This works just as described. I am able to activate each of the relays with a user defined code.

The unit works well and is very sensitive and responds accurately. It requires full 12v in order for the relays to pick reliably.My complaint is, the total lack of operation, programming and hookup information. However I found good detailed information the internet. Without it this unit would have been of little use. Do not tie the ground of the DTMF cable to the Negative power. I am using several of these
