Box
a. Footprint
b. Fastening
The ACW-THX is fixed to a wall with two screws that fit into the two fixing holes at the back of the case.
The holes of the cover must be on the right, in the same direction as the picture below.
c. Installation
For best results, it is recommended to install the box without environmental obstruction and to place it at a height of
about 1.5m. For information, the antenna is integrated in the box. It should be mounted on a vertical support, or fixed
to a wall.

d. Identification
The Sigfox or LoRaWAN identifier of the product is visible on the external label on the back of the product, inside on
the electronic board, and in the status bar of the ACW configurator. For LoRaWAN modems, the communication keys
are automatically given by the network (pairing by "Over The Air Activation", or OTAA).

Operation
a. Mode of operation
To find out the status of the product, you just need to pass a magnet briefly (<2 sec) against the QRCODE label,
which causes the LED to light up. The color of the LED indicates the operating mode of the product as
described:
Storage mode : When you take the product out of its packaging, it is by default in this storage mode,
which optimizes the life of the batteries by avoiding their oxidation. The product does not emit and waits
patiently for you to wake it up.
Network pairing mode : This mode is active as soon as the product leaves the storage mode and allows the
pairing to a network (automatic in case of battery change).
Configuration mode : This mode is active 5 minutes after the exit of the storage mode and authorizes the
configuration of the product in Bluetooth thanks to the PC configurator or to the mobile application ATIM. During
these 5 minutes messages are sent by radio every minute (5 "radio frames"), that allows you to check that the product
works well, for example after having placed it under a cast iron manhole. After this period, the product goes into
operation mode and the Bluetooth is deactivated (possibility to reactivate it via Downlink).
Operating mode : This is the default mode after the product start-up phase. In this mode, the module periodically
sends measurements according to the configuration applied (if the product has never been configured, the
factory configuration applies, see Factory Configuration).
Internal fault mode : This mode allows the normal operation of the module to be interrupted when a critical
event occurs. The nature of the event can be multiple:
- Battery empty (Battery voltage < 2.2V)
- Internal error of the radio module
- System error
The entry in this "Internal Fault" mode is signaled by a RED flashing of the product LED
If the error does not come from the radio module, the product will send a radio frame every 24 hours
containing the or the error codes (see chapter Frame format for error codes). In addition, the product will emit a
warning light depending on the nature of the event.
Once in this mode, the module must be restarted (by disconnecting and reconnecting the battery, by Downlink
command or with the magnet) to regain normal operation.
