8.6 EWS1 – Wireless Indoor Siren
EWS1 is a wireless device with built-in siren speaker and operates with ELDES wireless alarm systems. EWS1 has to be bind to the
alarm system by sending a corresponding SMS message or using software ELDES Conguration Tool. Upon successful EWS1 binding,
the system adds one wireless zone and one wireless PGM output. The wireless zone is used to monitor the device (tamper - when the
batteries are being removed) and the wireless PGM output is used to control the speaker. In case of alarm, the siren provides a sound
alarm for one minute. The conguration of this parameter is disabled for EWS1 in order to save the battery power.
It is possible to connect up to 16 EWS1 devices to the alarm system at a time. The maximum wireless connection range is 150 meters
(in open areas).
