EWF1 is a wireless photoelctric type smoke detector intended to use with ELDES wireless alarm systems. Photoelectric smoke detectors

are generally more eective at detecting smouldering res which smoulder for hours before bursting into ame. An optical method

is used for the detection of visible smoke. When the concentration of smoke in the optical chamber exceeds a given threshold, EWF1

sounds the alarm and sends out a signal to the ESIM264 alarm system using the wireless connection and the system triggers the alarm.

By default, when more than one EWF1 device is used, the system will automatically activate the interconnection feature (see 32.9.4.

In terconnection). ESIM264 system support up to 16 EWF1 devices, The maximum wireless connection range is 150 meters (in open

areas).
