The number of smoke alarms that can be interconnected depends on the method of interconnection and the specific model of the smoke alarms.
For hardwired interconnection, it is usually possible to connect up to 12 smoke alarms. This method involves using an additional wire laid alongside the 240v wiring at the time of installation.For wireless (RF) interconnection, up to 40 smoke alarms can be interconnected depending on the model1. These smoke alarms use wireless radio frequency (RF) transmissions to interconnect.
