1. DESCRIPTION AND OPERATION PRINCIPLE
The device is built into the housing of the smoke sensor ИП212-50М manufactured by LLC
"BORDER" (http://td.rubezh.ru/products/detail.php?ID=1694) and is designed to record the
change of smoke sensor state and to initialize the communication session with the transmission
of the alarm event when switching to the "Fire" mode.
The switching device can be used in industrial enterprises, infrastructure of housing and
communal facilities, in hard-to-reach places (wells, basements).
DATA COLLECTION AND TRANSMISSION ALGORITHM
The device monitors the current state of the smoke sensor and transmits data according
to predetermined frequency communication session in LoRaWAN network.
The transmission period of the current state can be set from 1 minute. By default, the
manufacturer sets the data transmission frequency to 1time a day.
If the Request Confirmation parameter is enabled, the switching device will send the next
package only after receiving delivery confirmation of the previous package. If you do not receive
such an acknowledgement after three replays, the switching device ends the session until the
next scheduled session. At the same time, the switching device stores the untransmitted data to
the memory. Non-transmitted packages remain in the switching device memory and are sent
during the next communication session.
If the Request Confirmation parameter is disabled, the switching device sends the current data
to the network with the specified frequency. There is no package delivery check in this mode.
Untransferred packages do not remain in the switching device memory.
The communication time of the switching device is controlled by the LoRaWAN network server
and can be adjusted by command.
The smoke detector ИП212-50М is powered by 9 V Krona power supply and the switching
device is powered by 3.6V power supply.
The switching device can be class A device (according to LoRaWAN classification) and
provides the following functionality:
• ADR (Adaptive Data Rate) support
• Wireless configurable LoRaWAN activation type in LoRaWAN network - OTAA, AVP;
