The device operates with a DC12V power supply and consumes up to 5W of power. It features a red LED indication and emits a sound pressure level (SPL) of at least 90 dB at 3 meters. The alarm is indicated by a red light flash combined with voice broadcast. The device functions within an operating temperature range of 0°C to +40°C and can handle humidity levels up to 95% RH without condensation. It operates on an RF frequency of 433 MHz with modulation types OOK and FSK, and adheres to RF protocols 1527 and 330K. It supports NB-IoT bands 5 and 8 and uses CoAP and LWM2M protocols. A backup power source is provided by a Li-ion battery (103040/DC3.7V). The device supports up to 64 or 128 sub-devices, depending on user requirements, with 64 being the default, and can also support up to 64 signal repeaters.
