Read the complete user manual before carrying out the installation and activating the system.
1. DESCRIPTION
The presence detector for ceiling mounting uses Passive Infrared Technology (PIR) and is suitable for indoor use. Lighting
control through motion detection is useful for small and large offices, rest rooms, changing rooms and larger storage areas.
The 1-channel presence detector (350-20054) controls only interior lighting. The 2-channel presence detector
(350-20055) has an additional potential-free relay contact to control interior lighting as well as ventilation.
2. INSTALLATION
2.1. Positioning
The presence detector reacts to motion and heat in its environment.
Installation tips:
- Position the presence detector with the light opening towards the incident light to obtain the ideal amount of daylight (fig. 1.A).
- Use the opening distance of 105 mm when the presence detector is mounted directly on the ceiling. The cable entry should
be rotated 45° relative to the mounting holes (fig. 1.B).
- If the presence detector is fitted to a flush-mounting box, use the provided holes and punch out the base cap (fig. 1.C). Carefully
and correctly install the cable according to the instructions for a fixed installation.
- Do not install the presence detector in locations where it is exposed to direct sunlight or near heat sources or air currents
(such as air conditioning).
- The recommended mounting height is 2.5 to 3 m.
- When placed over a desk, install the presence detector approximately 1 m from the seating area. The sensor has an optics
with two detection zones: a zone for small distances (A + B) to record small body movements and a zone for larger distances
(C + D) to record general body movements. This combination ensures excellent lighting control and optimal energy savings
(fig. 2).
Attention: Disconnect all power before installing the presence detector. Do not connect the device to the mains voltage until
installation is completed.
2.2. Mounting
Mounting the sensor (fig. 3)
- Insert the sensor into the terminal strip in the bottom layer of the base portion and install the safety screw
(Pozidriv (PZ) 0/Philips (PH) 1).
- Adjust the presence detector settings as described in section 3.2.
The detection area can also be limited as described in section 3.2.4.
- Install the cover on the sensor.
