What is EWF1?
EWF1 is a wireless photoelectric-based smoke detector designed to detect smouldering fire before bursting into flame.
How EWF1 works?
EWF1 has to be bind to the alarm system by sending a corresponding SMS message or using software ELDES Configuration Tool.
Upon successful EWF1 binding process, the system adds one wireless zone. In case of smoke detection, EWF1 will indicate the alarm by built-in speaker and notify ELDES system about the event.
