Motion sensor
Motion sensors are passive infra-red (PIR) devices
that detect activity. The diagram shows the detection
pattern of motion sensors.
The motion sensor must have an uninterrupted view
directly in front and to the sides.
The preferred location of the motion sensor is in the
upper section or in header panel of the cooler to
ensure the best motion detection and to lower the
risk of the motion sensor being blocked by objects
such as packages.
For the controllers without integrated motion sensor, a remote motion sensor can be used.
The remote motion
sensor head is supplied
detached from the cable
to allow the cable to be
easily routed through
holes or foamed into
place as required by the
OEM or installer.
The motion sensor should be mounted vertically with the connector at the bottom for optimal
performance. Mounting horizontally with the connector at the side results in the motion sensor being less
sensitive. However, the motion sensor still works correctly.
The motion sensor must not be located behind any material such as glass or polycarbonate.
