Attention!
ALARM DETECTED…
Nexo will send you an SMS the moment it detects a threat, such as flooding, burglary, fire, or the presence of sleep-inducing gas. It can even indicate the specific sensor and room where the alarm was triggered, allowing you to quickly locate the source and take appropriate action.
STAY IN THE LOOP…
Are you and your spouse away for a while and your child is taking care of the house?
Nexo can send you messages whenever the alarm system is armed or disarmed, letting you know exactly when your child leaves or returns home.


TALK TO YOUR HOME VIA SMS
The GSM card not only sends alerts but also receives user commands. By sending an empty SMS, you’ll get a list of commands the system recognizes. For example, sending: arm Home “password” will activate the alarm and confirm with a reply: Home partition armed.
You can also define custom SMS commands using Nexo logic. For instance, sending: Is the convertible in the driveway? could trigger a response like: The car is safely parked, based on sensor input.
IRON — ON OR OFF?
With the GSM card, you can ask: “Is the iron in the laundry room off?”
If the 230V socket is active, the system replies: “Yes. Should I turn it off?”
Replying “Yes” deactivates the socket and confirms: “Done.”


Everything in its place
NEXO DISTRIBUTION BOARD
To make it easier for the installer to mount the modules in the distribution board, each one is equipped with appropriate connectors that allow control wires to be connected outside the module and then plug the prepared wiring harness into the corresponding socket. This method of work ensures proper connection quality and reliable operation of the module for years.
An additional convenience is the system bus bar, which provides digital communication between devices. Thanks to its use, module startup is quick, and communication line connections are durable and dependable. The entire setup is also aesthetically pleasing and easy to understand for any engineer.
TEXT WITH YOUR HOME
- The GSM card also allows you to control the system. Sending a previously defined command will activate selected functions or circuits. This option is particularly useful when you’re away from home and don’t have internet access, but an action is required on your part (e.g., opening the gate for a courier).
- Would you like to receive an SMS every time the postman puts a parcel in your mailbox?
- To achieve this, simply equip the mailbox with a sensor and properly program the system. Nothing will escape your attention.
- Is it raining, and one of the windows is open?
- Nexo will send you an SMS with the relevant information so you have time to react before an unpleasant surprise occurs.
