Mixed Hardwired Interconnect and Wireless Interconnect (Hybrid) System
Ei3000 Series Alarms are also equipped to work in a hybrid system. A hybrid system is a
combination of hardwired interconnected and RF interconnected Alarms and devices. Hybrid
systems can be very flexible and allow extended fire and/or CO protection with minimum
installation disruption.
Hybrid Systems should be not be installed where specific alarm type (Fire or CO) indication
is critical - for example, if required to trigger switching equipment depending on the alarm
type detected. This is because the hardwire interconnect line does not communicate the
alarm type, whereas the RF interconnection does. Therefore, we recommend using RF only
interconnected Ei3000 series Alarms where specific alarm type indication is required.
