Every room is supplied with one or more motion detectors and fire detectors. These transducers are connected to digital inputs on P-NET modules.
The fire detectors are monitored 24 hours a day, and any problem results in a periodic activation of the alarm bell.
When the alarm system is active, any abnormal signals from window and door switches, motion detectors, and fire detectors, or a possible breakdown in the PC network, and any exceeded criteria for maximum temperature and humidity levels, will cause the P-NET master performing the surveillance task, to send an alarm signal to the ATIM. This in turn passes on the signal to the security company.
