Wireless water alarm 868.3 MHz
Wireless water alarm 868.3 MHz
WARNING!
CHEMICAL BURNS!
Keep batteries away from children.
The device contains a lithium button cell. If a new or drained button
cell is swallowed or enters the body it can lead to severe internal
chemical burns and can cause death within two hours of ingestion.
Always ensure that the battery compartment is securely shut. If the
battery compartment does not close correctly, stop using the device,
remove the battery and keep it away from children.
If you believe that a button cell has been swallowed or has
entered someone's body, seek immediate medical attention.
The batteries must be disposed of correctly, even if they have
been kept away from children.
Even used batteries can cause injuries.
Intended use
The wireless water detector is solely intended to detect the presence
of water in indoor areas and to notify the BrematicPRO Gateway of this.
Information about Wireless Operation
This device uses the 868.3 MHz proprietary wireless protocol. Wireless
transmission is implemented using a non-exclusive channel, interference
can therefore not be excluded.
The range in building may vary greatly from open areas. In addition to
the transmission power and the reception characteristics of the receivers,
ambient conditions, e.g. humidity in addition to the structural conditions
on site, are important factors.
The range can be significantly reduced in part due to:
• wood, gypsum, concrete, reinforced concrete walls
• proximity to metal and conductive objects
• broadband interference, e.g. in residential areas (DECT phones,
mobiles, wireless headphones, wireless speakers, wireless
weather stations, baby monitors)
• proximity to electric motors, transformers, mains adapters, computers
Duty cycle
Duty cycle refers to a transmission time limit regulated by law for devices
transmitting in the 868 MHz range. It is intended to ensure smooth
operation of devices operating in the 868 MHz range. The maximum
transmission time of each device is 1 % of an hour (corresponding to
36 seconds / hour). Once the 1 % limit has been reached it cannot transmit
until the time limit of the duty cycle has ended, so after one hour.
