77 EN EWR2 Wireless Signal Repeater v1.1
5. TEMPERATURE SENSORS
EWR2 allows user to add up to 8 temperature sensors, intended for temperature measurement in 8 different surrounding areas in real-time.
1 -Wire input requires only one port pin for communication with sensor. User may use a single temperature sensor or multiple temperature
sensors simultaneously – wire up one after another in parallel – until the number of 8 sensors is reached. Once the temperature sensor (-s) is
wired, it is necessary to enable it, using ELDES Configuration Tool software (after pairing EWR2 device with the system). This function is valid
for: ESIM364 v02.11.00 and up; EPIR3 v01.07.00 and up. For more details on how to configure and pair the device with the system, please refer
to ELDES Configuration Tool software’s HELP section or ESIM364 user manual.

EWR2 begins expanding the signal range for
wireless devices if the certain conditions are
met. In order for EWR2 to function properly,
the wireless signal level between EWR2 and
ELDES alarm system must be at least 18%
(see Fig. No 13 ).
