6. Upon the successful binding process, EWS2 device icon becomes visible in Wireless Device section as well as Battery Level and
Signal Level. If attempt to bind is unsuccessful, try to move EWS2 closer to the alarm system device and bind anew.
7. EWS2 siren is ready for use.
NOTE: If you are unable to bind the wireless device, please, restore the parameters of the wireless device to default and try again.
See chapter 6. Restoring Default Parameters for more details.
4. EWS2 Zone, PGM Output & Tamper
Upon successful EWS2 outdoor siren binding process,the system adds 1 wireless Instant zone and 1 wireless Siren PGM output. The
wireless zone is intended for EWS2 tamper control and the wireless PGM output is for siren control.
In case of tamper violation, the alarm is caused regardless of system being armed or disarmed. There are 2 ways to detect tamper
violation on EWS2:
• By tamper button. EWS2 has a built-in tamper button intended for monitoring the enclosure status. Once the enclosure
of EWS2 is illegally opened, the tamper button becomes unpressed. This action is followed by alarm which is sent by SMS
message and phone call to the user (-s) by default. The SMS message contains the violated tamper number.
• By wireless connection loss. The wireless connection loss between EWS2 and ELDES alarm system leads to alarm. The sys-
tem identies this event as a tamper violation and sends alarm by SMS message and phone call to the user (-s) by default.
The SMS message contains the violated tamper number and a star * character indicating wireless connection loss as a tamper
alarm cause.
ATTENTION: The tamper will not operate if the wireless zone is disabled.
5. Battery Replacement
