- If the device was in REPLI mode before changing the battery, press the button.
After this procedure the device will behave as during a first start (paragraph 5.7).
- If the device was not in REPLI mode when the battery was changed then it will au-
tomatically detect it after sending a few frames and erase the low battery indicators
(status and LED).
In order to be able to combine a dry contact sensor with the device and thus benefit from its Digital
Input 2, it is necessary to connect the sensor to the terminal block of the card.
Connection procedure for the wires:
1. Open the unit (paragraph 5.1)
2. Plug the two wires into each notch of the terminal block
3. Break the element of the casing so as to pass the wire onto the back of the casing
4. Configure the digital input 2 alarm (section 3.3.1.04)
5. Close the unit
6. Restart the device with the button as for a first start
After this procedure the device will behave as during a first start (paragraph 5.7)
E.g.:
The LoRaWAN SmartBuilding COMFORT device can easily be combined with a cabled door contact via
the terminal block (Digital Input 2). Thus, positioned next to the door of a secure room under control,
the device will be able to send an alarm every time the door is opened/closed and thus enable the se-
curity manager or the building manager to verify compliance with the security requirements on the site.
