Installation and operation
Installation
The housing is intended to be installed inside or outside a building but it must be protected from vertical water spray and direct sunlight.
Casing
Flammability rating: UL94HB
Ingress protection: IP55 or IP68 48 hours @1m
Radio propagation
In order for the sensor to operate correctly, the number of obstacles should be limited in order to avoid excessive radio wave attenuation. It is also important to place the sensor as high as possible. The cable gland should be positioned on left side.
Autonomy
The information in the table below represents how long the battery can last. It is based on the default configuration at ambient temperature (+25°C) within the optimal operating range of the sensor via a LoRaWAN network (one uplink frame), when the spreading factor used is SF12.
The disposable battery has a 3.6Ah capacity, of which 85% is used.
| Transmission periodicity | Repetition | Spreading Factor | Battery life | comments |
|---|---|---|---|---|
| 12h - standard report | 0% | SF12 | >10 years | only one value among all |
| 4h - standard report | 200% | SF12 | >10 years | only one value among all |
| 2h - standard report | 0% | SF12 | >10 years | only one value among all |
| 1h - standard report | 0% | SF12 | >8 years | only one value among all |
| 1h - standard report | 200% | SF12 | >3 years | only one value among all |
| 1h - standard report | 200% | SF9 | >10 years | only one value among all |
| 4h - batch report | 0% | SF12 | >10 years | 3 binary inputs counter 1 hour recording |
| 4h - standard report 1h - measure of 4-20mA | 0% | SF12 | >10 years | only one value of 4-20mA |
A value of 3µA of consumption is added per input connected (contact closed).
Human Machine Interface
There are Two LEDs on the Toran'O AtEX zone 1 device:
ASSN: blinking until the association with a network is done. Since release v3.5.2.5530, after 6 hours in association searching the led blinks all 1 minute.
CNF: blinking in configuration mode.
To start up the device, a magnet must be placed next to the sensor for one second (behind the "ILS" sticker). The red LED blinks quickly during this step. After one second, the red LED stops blinking and the green LED blinks slowly until the association is done.
To switch off the device, repeat the same operation by placing the magnet next to the sensor for 5 seconds. After those 5 seconds, the red LED blinks 5 times slowly.
A reed switch is available under the "ILS" sticker. A magnet can be used to activate it and perform specific actions on the sensor (switch off, switch on, reassociation…). When the reed switch is activated, the red LED blinks quickly.
- Configuration
| Way to trigger it | One passage of the magnet near the reed switch or specific ZCL command |
| Way to stop it | Another passage of the magnet or specific ZCL command |
| Effects on the sensor | The CONF led (red) blinks (3 sec. OFF, 3 sec. ON) and the sensor sends an uplink frame every minute. |
| Duration | The configuration mode lasts 10 minutes |
- A reassociation procedure can be requested if no downlink frame is received by the sensor during a given periodicity (4 days by default) or if a given number (100 by default) is reached or in case of failure (no acknowledgement received) by sending an applicative frame to the sensor or via the sensor’s IHM.
The sensor keeps the AppEUi and DevAddr configured, Confirmed/Unconfirmed configuration and all applicative configurations. However, LoRaWAN configurations (channel, data rate …) are lost.
| Way to trigger it | Three passages of the magnet near the reed switch or ZCL command from LoRaWAN cluster. |
| Effects on the sensor | The ASSN led (green) blinks as the “no commissioned sensor” LED is lit. |
- A factory reset is available on Watteco’s sensors. It deletes all the applicative settings saved in the flash memory (i.e. configured batches and reports will be deleted).
The sensor keeps the AppEUi and DevAddr configured. However, LoRaWAN configurations (channel, data rate…) and applicative configurations are lost.
| Way to trigger it | Two quick passages and a long passage of the magnet near the reed switch |
| Effects on the sensor | The CONF LED (red) and ASSN LED (green) blink at the same time briefly. All the applicative settings (for batches and reports) are deleted. The blinking is illustrated below this table. |

The Toran'O AtEx Zone 1 device implements “Binary Input” cluster associated to its Inputs. The link between the connectors and the EndPoint is given below:
| Connector C | End Point | Cluster | Fctrl |
|---|---|---|---|
| Input 1+/1- | 0 | Binary Input | 11 |
| Input 2+/2- | 1 | Binary Input | 31 |
| Input 3+/3- | 2 | Binary Input | 51 |
The Toran'O AtEx Zone 1 device implements “Analog Input” cluster associated to its 4-20mA and 0-5V Inputs. The link between the connectors and the EndPoint is given below:
| Connector A | End Point | Cluster | Pins |
|---|---|---|---|
| 4-20mA | 0 | Analog Input | Pin1: OUT V+ Pin2: GND Pin3: IN 4-20mA |
| Connector B | End Point | Cluster | Pins | comments |
|---|---|---|---|---|
| 0-5V [mV] | 1 | Analog Input | Pin1: OUT V+ Pin2: GND Pin3: IN-Measure-1 | |
| 0-5V [mV] | 2 | Analog Input | Pin1: OUT V+ Pin2: GND Pin6: IN-Measure-2 | |
| 0-5V [ratiometric %] | 3 | Analog Input | Pin1: OUT V+ Pin2: GND Pin3: IN-Measure-1 | % of OUT. EndPoint 3 & 4 are based on the same periodicity of measure and the same duration of alimentation. So the minimum configuration on Endpoint 3 or 4 set this periodicity. And the duration of alimentation is the maximum configured on Enpoint 3 or 4. |
| 0-5V [ratiometric %] | 4 | Analog Input | Pin1: OUT V+ Pin2: GND Pin6: IN-Measure-2 | % of OUT. EndPoint 3 & 4 are based on the same periodicity of measure and the same duration of alimentation. So the minimum configuration on Endpoint 3 or 4 set this periodicity. And the duration of alimentation is the maximum configured on Enpoint 3 or 4. |
Toran'O integrates the following clusters:
| Cluster | Cluster name | Managed attributes |
|---|---|---|
| 0x0000 | Basic | All |
| 0x0050 | Configuration | All |
| 0x000F | Binary Input | All |
| 0x8004 | LoRaWAN | All |
| 0x8005 | Multi Binary Inputs | All |
| 0x000C | Analog Inputs | All Threshold is available with 4 slots |
Default configuration
A default configuration is set:
- The device reports:
- the counter value associated with input 1+/1- (EndPoint 0 / Cluster Binary Input / Attribute Count), input 2+/2- (EndPoint 1 / Cluster Binary Input / Attribute Count), and input 3+/3- (EndPoint 2 / Cluster Binary Input / Attribute Count) each day in standard mode.
- the 4-20mA input each day in standard mode.
- the two 0-5V inputs each day in standard mode.
- the battery level each 7 days or on 100mV variation.
Every change made to the default configuration must comply with the legal duty cycle (for example, the most restrictive in the EU is 0.1%, which corresponds to approximately 1 frame per hour with SF12)

• Configure a batch report on connector input 2+/2- and connector input 3+/3-:
Timestamp and record Input 2+/2- every 200 pulses; and timestamp and record the level of Input 3+/3-. A report has to be sent at least every 24 hours:
→A counter on Input 2+/2- is the End Point 1, Cluster “Binary Input” is 0x000F, and Attribute “Count” is 0x0402.
A level on Input 3+/3- is End Point 2, Cluster “Binary Input” is 0x000F, and Attribute “Present Value” is 0x0055.
There are two different measurements to be recorded in the batch, use the default tag size 4. Label 1 can be used for counter and Label 5 for level.
For counter, the delta is 200 and resolution 1. For level, the delta is 1 and resolution 1. The maximum has to be configured for all to 0x850a.
Two frames must be sent to configure this batch.
| Label number | Tag label | Tag size |
|---|---|---|
| 1 or 2 | 0/1 | 1 |
| 3 or 4 | 00/01/11/10 | 2 |
| 5 or 6 or 7 or 8 | 000/001/010/011/100/101/110/111 | 3 |
| ... | ... | ... |
