EWS3 – Wireless Indoor Siren
4. EWS3 ZONE, PGM OUTPUT AND TAMPER
Upon successful EWS3 outdoor siren binding process,the system adds 1 wireless Instant zone and 1 wireless Siren PGM output. The
wireless zone is intended for EWS3 tamper control and ability to assign a partition (-s), while the wireless PGM output is intended for siren
speaker control.
In case of tamper violation, the alarm is caused regardless of system being armed or disarmed. There are 2 ways to detect tamper viola-
tion on EWS3:
• By tamper switch.
EWS3 comes equipped with 2 built-in tamper switches intended for enclosure supervision:
• one located on the front side of the PCB supervising the front cover in case it is illegally opened (see Fig. No. 1).
• the other one located on back of the PCB supervising the back side of the enclosure in case the EWS3 is illegally detached from the
wall (see Fig. No. 1).
Once the enclosure of EWS3 is tampered, the tamper switch will become triggered. This action will be followed by alarm, resulting in
sending an SMS text message and/or phone call to the user. The SMS text message contains the violated tamper number.
• By wireless connection loss.
The wireless connection loss between EWS3 and ELDES alarm system leads to alarm. The system
identifies this event as a tamper violation and sends an alarm by SMS text 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.
