OCCUPANCY DETECTOR
INTRODUCTION
electra e3.1 is a 360 degree flush mount occupancy
detector that uses a passive infrared sensor to detect
changes in temperature emitted by persons or objects
passing through its detecting area.
electra e3.1 is a slave detector that can only be
installed in a “master/slave” connection.

SAFETY PRECAUTIONS
Avoid installing the unit in storming weather.
Be sure to isolate or switch off power source
before installing or maintenance.
DO ensure that the power supply circuit is
protected by a 16 amp circuit breaker or suitable
equivalent fuse.
IMPORTANT
Installation must be performed by skilled
technicians who are informed about the standards
and technical requirements of the appliance and its
proper installation.
Check your local codes as they apply to your
situation. If the house wiring is of aluminum,
consult with an electrician about proper wiring
methods.
Before proceeding with the installation, TURN OFF
THE POWER TO THE LIGHTING CIRCUIT AT
THE CIRCUIT BREAKER OR FUSE BOX TO
AVOID ELECTRICAL SHOCK.
CHOOSING A MOUNTING LOCATION
When deciding a proper location to install the unit,
please take the following points into consideration:
The unit is designed for indoor ceiling flush mount
and is not suitable for wall mount.
The occupancy detector is more sensitive to an
object moving across its field of view. It is less
sensitive to an object moving directly towards the
sensor head. (FIGURE 1)
FIGURE 1
The unit has a sensing angle of 360° and can
detect up to 3 meters radius for micro motion and
up to 5 meters radius for walk across motion at
the mounting height of 2.5 meters. (FIGURE 2)

INSTALLATION
(1) Switch off the power source or wall switch before
installing.
(2) In order to install the sensor, drill a round hole of
about 70mm in diameter on the drop ceiling.
Turn both spring clips upward so they can fit into
the hole. (FIGURE 3)
