Read the complete user manual before carrying out the installation and activating the system. Keep
the manual for future reference.
1. DESCRIPTION
Thanks to its elliptical detection range of up to 40 m, this flush-mounting motion detector is particularly suitable
for landings and corridors. The detector registers movement via a passive infrared sensor (PIR). It is most
sensitive to movements passing through the detection area. The sensitivity to movements directly towards the
sensor is about 50% less.
The detector only switches on once the set daylight condition (twilight level) is no longer reached. The duration
of activation is extended as long as movements of persons are detected and is switched off once motion is no
longer detected.
2. USE
The detector is suitable for controlling lighting in landings and corridors.
Be aware of the following during installation:
• Only mount the detector indoors and on stable ceilings.
• In order to ensure the correct detection radius, place the detector in such a manner that the sensors are
pointed lengthways down the corridor (see Fig. 1).
• Hide any moving objects in the detection area by shielding the lens.
• Do not place any lighting closer than 1 m from the sensor (see Fig 2).
• Do not mount the motion detector in the path of direct cold or hot air flow.
• This product needs to be installed in a flush-mounting box with dimensions according to the CEE7 standard
sheet XIII or XV and a minimum flush mounting depth of 40 mm.
3. MOUNTING
The detector is designed for mounting on the ceiling at a height of 2 to 8 m. The range of the detection area
depends on the mounting height (see Fig. 1):
Mounting:
1. Remove the lens of the detector
2. Connect the detector as shown in the wiring diagram in Fig. 5 (also see § 4).
3. Secure the detector in a standard 68 mm flush-mounting box.
4. Configure the detector (see § 6).
5. Mount the lens on the detector.
4. WIRING
Connect the detector as shown in the wiring diagram in Fig. 5.
You can switch the conductor to the R input on and off with an external push button. Use a N.O. push button
without indication LED and limit the length of the electrical wires.

Neutral conductor
Switched output relay
N.O. push button
Below several connection examples are shown:
• connection of a push button (to be purchased separately) for manually switching on and off (see Fig. 5)
• connection of several short-impulse function (SI) motion detectors for use with a time relay, staircase timer,
doorbell, ... (see Fig. 6)
• parallel connection of multiple motion detectors with extra switch for permanent lighting (see Fig. 7)
5. CONNECTING DEVICES
A high inrush current decreases the life span of the relay integrated into the detector. Respect the technical
specifications of the lighting manufacturers to prevent overloading the relay. We recommend connecting a
maximum of 3 to 4 detectors in parallel. This keeps the switching circuit organised. If the number of switching
cycles is higher than average or in case of an increased load, we recommend to run the load via an external
relay or an external fuse.
6. CONFIGURATION
The detector is ready for use approximately 1 minute after connection to the electricity grid. The settings can
only be changed while the detector is switched on. The settings can be changed using the rotary switches on the
device or using the remote control 351-25320 (to be purchased separately).
6.1. Switch-off delay
Using the TIME potentiometer, the switch-off delay after the final movement is set (see Fig. 3). When the
relay output is connected to a staircase timer, set the TIME switch to 'pulse'
351-25320 (to be purchased separately), the pulse function can be further set (approx. 1 s with approx. 20 s
or approx. 60 s break).
6.2. Light sensitivity
Using the LUX potentiometer, you can set the threshold value of the twilight switch continuously between ð
(daytime mode, 2000 lux) and ƒ (night mode, 5 lux) (see Fig. 3).
6.3. Detection range
Using the SENS potentiometer, you can set the sensitivity of the PIR sensor (see Fig. 3).
7. EXTERNAL PUSH BUTTON
When you use the detector as an absence detector, you need to connect an external push button with which
you can switch the light on (see Fig. 5).
When you use the detector as a presence detector, the external push button is optional. The light will automatically
switch on when movement is detected. The light can always be switched on or off manually using the external
push button. The duration of the switch position (on or off) is extended as long as movements are detected.
After the last detected movement the switch position is maintained for the period set.
Please note: if the TIME switch is set to 'pulse', the detector can not be switched on manually.
• Keep the external push button pressed for 0.1 to 2 s to activate or deactivate automatic operation.
• Keep the external push button pressed for 2 to 4 s to switch the detector on for 6h. To cancel this switch
position, briefly press the button again.
• Keep the external push button pressed for longer than 4 s to switch the detector off for 6h. To cancel this
switch position, briefly press the button again.

8. DISPLAY
The statuses pictured below are shown with the indication LED on the device. You can change the settings using
the potentiometers on the device or the remote control 351-25320 (to be purchased separately). If a setting is
changed, the relay output of the detector will switch off briefly.
