Environmental recommendations

a. Explosive atmosphere

Except for the ACW-ATEX line specifically intended for this purpose, do not use ACW radio modems in the presence of

flammable gases or fumes. Using the equipment in such an environment constitutes a safety hazard.

b. Environment

Respect the temperature ranges for storage and operation of all products. Failing to respect these guidelines could

disrupt device operation or damage the equipment. ACW products in IP65 water- and dust-resistant housings may be

placed outdoors but must not be submerged under any circumstances.

Follow the instructions and warnings provided below to ensure your own safety and that of the environment and to

protect your device from any potential damage.

ATIM_ACW-WLL_UG_EN_V1.4

General hazard –Failure to follow the instructions presents a risk of equipment damage.

Electrical hazard –Failure to follow the instructions presents a risk of electrocution and

physical injury.

management service, or the business from which you purchased the product.

c. Radio

Modems in the ACW line are radio-communication modems that use the ISM (industrial, scientific, and medical) bands,

which may be used freely (at no cost and with no authorization required) for industrial, scientific, and medical

applications.

the product response time)

a. Mounting

ACW-WL(L) modems are fixed on a flat wall using the 4 fixing holes available at each

end of the case. For best results, it is recommended to install the case without

environmental obstruction and to place it at a minimum height of 2m. For

information, the antenna is integrated into the box. It must be mounted on a

vertical support or attached to a wall

b. Identification

The product identifier is visible on the outer label on the back of the product, on the inside of the electronic board and

in the status bar of the configuration software.

For LoRaWAN modems the communication keys are automatically given by the network ("Over The Air Activation", or

OTAA pairing).

Each product in the ATIM ACW range has a QR Code label visible either on the side or on the front of the product.

This QR code can be easily read with any 2D barcode reader application on a smartphone.

Reading this code indicates the following information:

Available versions

a. Electrodes only

In this version, the sensor can detect a leak just under itself like in this

picture.

It must be placed to get the electrodes right above the floor

REF: ACW-WL-I

b. Simple cable

In this version, the product is using a water sensible cable and therefore can detect the

presence of water all long the cable.

It’s available in different lengths (3m / 5m / 7m / 15m).

ATIM_ACW-WLL_UG_EN_V1.4

c. Localisation and detection cable

Using this cable, you can locate the leak by measuring the distance between the device

and the leak with a precision of +/- 1m.

This cable is available in different lengths: 5m / 7m / 10m / 15m and can be connected

to various accessories to monitor several rooms at the same time. Each segment features

a male and a female waterproof connector to be extended easily.

REF: CAB-WLL-3 / 5 / 7 / 15
