Dual Tech Wall-mount Occupancy 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, PIR detection and 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 occupancy in the space has only been triggered 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, PIR detection and 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
A sensor that is set for Basic configuration mode (DIP switch 2 set to Off)
can be further configured locally using the other available DIP switch
settings, and the [MODE] and Auxiliary [A] buttons and their associated
LEDs. See
Program Mode on the facing page
Custom
A sensor that is set for Custom configuration mode (DIP switch 2 set to
On, the default setting) can be customized using the EchoAccess App. For
more detailed information about custom configuration options available,
see the EchoAccess App integrated help system.
