350-20081
Read the complete manual before carrying out the installation and activating the system. Keep the
manual for future reference.
1. DESCRIPTION
The presence or absence detector 360° (secondary) for surface mounting on high ceilings consists
of an integral unit with on-off control of one channel and a motion sensor (PIR or passive infrared technology).
You will use this device in combination with a master (350-20080) to increase the detection area (see section
4.2.).
The secondary detector will control the lighting according to the parameters set on the master. For more
information, please refer to the manual supplied with the master.
2. INSTALLATION
2.1. Connection
Danger: Disconnect all power before installing the detector. Do not connect the device to the mains voltage
until installation has been completed.
Refer to the wiring diagram (fig. 1).
2.2. Mounting
Tip: Do not install the detector in the vicinity of heat sources such as stoves or electric heaters, air currents
(ventilation systems) or any moving objects (fig. 2). This can activate the device unnecessarily as it reacts to
motion and heat in its surroundings. If the detector is installed in warehouses where closed trucks are used,
its operation may be less than optimal due to temperature differences that are too small.
Tip: The recommended mounting height is 4 to 8 m. At this height, the detector has a range with a diameter
of 16 to 32 m on the ground (fig. 3).
The detector is suited for direct mounting on high ceilings (fig. 4).
At delivery, the cover mask is mounted on the detector (see also section 4.2.).
3. SETTINGS

3.1. DIP switches

Using the two DIP switches you set the sensitivity of the motion sensor. You can choose from the following
options: minimum, low, high or maximum. Refer to figure 5 for the position of the DIP switches depending on
the desired sensitivity.
At delivery the motion sensor of this detector is set at the high sensitivity mode.
3.2. Potentiometer
Contrary to the master, the housing of the secondary detector includes only one potentiometer with one single
function, i.e. activating the walking test (fig. 6).
The detection area is tested by activating the integrated motion sensor for the walking test:
1. Set the potentiometer to the minimum value.
The blue indication LED lights up when you activate the test mode.
The lighting is switched on for five seconds and the red indication LED lights up each time the sensor
detects activity. If no activity is detected and the sensor is still in test mode, the blue indication LED lights
up.
2. Set the potentiometer back to the middle value as soon as the walking test is completed.
If you forget to close the test mode, the detector will return to the selected settings after five minutes.
4. OPERATION AND USE
4.1. Activation
The detector should not be powered until all cables are connected. After powering the device, the detector will
be ready for use after approximately 40 seconds (warm-up time).
The red indication LED flashes during warm-up time. After the device has warmed up, the green indication
LED will flash briefly twice.

4.2. Detection range

The detection area can be increased by adding an extra detector (secondary) (350-20081). A maximum of ten
secondary detectors can be connected to one master (350-20080). The lighting is operated in accordance
with the settings on the master. Both the master and the secondary detector have the same detection
range (a circle with a diameter of 16 to 32 m). When covering a complete area using several detectors, it is
recommended to take into account an overlap of approximately 30% (fig. 7).
If you would like to exclude motion detection in a portion of the detection area or if the detection area is too
large, you cover the sensor lens using the cover mask supplied. This allows you to reduce the maximum range
to 32 m. The 360° detection angle can be reduced in steps of 30°.
5. MAINTENANCE
Dirt may prevent the detector from functioning properly. Therefore, always keep the lens clean and dry. Use a
damp cloth and water with some detergent to clean the lens. Never exert pressure to wipe the lens clean. If
the lens or other parts of the detector are defective, please contact an authorised installer.
