Change the phone number in the 1234,1,... command to your own. You can add 3 more numbers if you like by
using:-
1234,1,+447111111111, +447111111112, +447111111113, +447111111114,
Every minute the device will apply 5 volts to +V for each input (one at a time).
The device will send a text message once per day as a health check. To stop this change the ‘1439’ in the
1234,2, command to ‘0’.
The inputs are configured as voltage, scaled 0 to 100 so when the circuit is made the input is read as 50.
For each channel there are 2 thresholds shown – a LOW alarm at 20, so when the circuit opens and the
reading drops to 0 this alarm is breached and a text sent. There is also a HIGH alarm set at 40 so when the
circuit is made the reading increases to 50 and this alarm is breached and a text message sent.
Connect the volt free contact to +V and IN.
