37 – DTMF 2-Digit and Command
$32.95 – $82.95
DTMF (Dual Tone Multi-Frequency) Two-Digit and Command requires two digits to operate, one number to arm the device, and one number to fire. The numbers selected are hardcoded but can be changed by making edits to the code. There is no internal timer. The device, by default, fires for 5 seconds before resetting (including disarming). The default code is 3 to arm and 7 to fire. Again, these can be modified in the code.
