EWS2 is a wireless outdoor device with a built-in siren speaker, LED indicators and operates with ELDES wireless alarm systems. EWS2
has to be bind to the alarm system by sending a corresponding SMS message or using software ELDES Configuration Tool. Upon successful EWS2 binding process, the system adds one wireless zone and one wireless PGM output. In case of alarm, the siren provides
a sound alarm for one minute. The configuration of this parameter is disabled for EWS2 in order to save the battery power.
ESIM264, EPIR and EPIR2 alarm systems support up to 16 EWS2 devices, while ESIM364 - up to 32 EWS2 devices.. The maximum wireless connection range is 150 meters (in open areas).

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 system identifies 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
1. Open EWS2 enclosure.
2. Remove all 4 old batteries from the battery slots.
3. Postition the 4 new 1,5V alkaline AA type batteries according to the appropriate battery slot positive/negative terminals indicated
on the PCB (printed-circuit-board) of EWS2
4. Insert the batteries into the battery slots.
5. Batteries replaced.
