Tunnel – Voice call alarm to change up to 8 digital inputs.
¿Buscas alguna otra cosa?
Scenario details:
- 8 dry contact sensors need to be monitored
- In the event of an activation in any of them, a voice call must be made to several phone numbers
- The phone numbers that will receive the SMS alerts are +34666123456, + 34666123457 and +346661234568
- To avoid making a large number of voice calls (in case of rapid changes in a certain entry), a timeout of 5 minutes should be established per entry, that is, no more than 1 call will be made in a 5-minute window by activating a certain input
Solution: MTX-Tunnel firmware + MTX-IOT-S [4-N]
Configuration example (config.txt file) for the indicated scenario:

Details:
- The configuration of the inputs as “call; 1; 300” indicates the following:
“call” > The input is configured to send alarm by voice call (the voice call will be made, but will not play any audio on the other end of the phone
“1” > The 2 indicates that the digital input is configured to make the voice call by activation of the input (when it closes taking it to ground)
“300” > Indicates the timeout of the digital input, in seconds. This means that, even if there are multiple changes in the digital input, there will never be more than 1 call in a 5-minute window (5 minutes = 300 seconds)
