How does the By-me SAI burglar alarm system work?

The devices are all connected in parallel to a dedicated 29V powered BUS line which is filtered by a backup unit that doubles as an indoor siren. In the control unit, you can associate the devices and group them into 31 different zones (even with multiple devices per zone). One such area could for example be associated with a room and when you arm the system, you can decide zone-by-zone whether the devices must trigger an alarm or not. Such partitioning can be differentiated according to which transponder key is activating the SAI burglar alarm, or according to different activation points around the house (associating different activation zones to different Transponder readers, RF Interfaces for remote controls, or the main control unit). It is possible to change specific relay states according to various alarm classes: Tamper, Technical, Panic, etc.
