Dual Tech Wall-mount Vacancy Sensor
Power Up
All EchoConnect terminations in the system must be made before
applying power to the system and sensor. When the sensor is powered,
the PIR and acoustic detection LEDs illuminate for one minute for
calibration and warm-up, and then return to normal operation according
to the configuration.
Both the PIR and acoustic detection features of the sensor will
automatically adjust the sensitivity threshold to eliminate nuisance
tripping. During this time, configuration is not allowed and no events are
triggered.

Operation

Dual Technology
When both PIR and acoustic detection are used, the following logic is
used:
• When the space is vacant, only manual control can switch the state
to occupied.
• When the space is occupied, PIR, acoustic detection, and manual
control can reset the vacancy timeout.
• When the vacancy timeout in the space has only been reset by
acoustic detection for 60 minutes, acoustic detection is disabled
until the next PIR detection event.
PIR (only) Detection
When acoustic detection is disabled (DIP switch 6 set to On), the
following logic is used:
• When the space is vacant, only manual control can switch the state
to occupied.
• When the space is occupied, PIR detection and manual control can
reset the vacancy timeout.
Configuration
Basic
When the sensor is in Basic configuration mode (DIP switch 2 set to Off),
the sensor will activate a Space Off command when vacancy is detected.
