Features and Connections
DALI connection
The DALI connection is made via DA+ and DA– terminals.
The DALI input is not polarity sensitive (unless you are
using an external power supply).
Optional connection to external power
12 V to 24 V. See ‘External Power Supply (Optional)’ on page 3.

The Low-Profile Microwave Detector provides occupancy detection for the automatic control of DALI lighting loads.
The unit can also be controlled using a Helvar infrared remote handset, such as the 303 DIGIDIM Infrared Remote Control.
Helvar’s 313 detects movement using its highly sensitive microwave detector. It works by emitting low-power microwave
signals and measuring the reflections as the signals bounce off moving objects.
When an area is no longer occupied, the load will switch off after a certain time. This time-out period is configured using
Helvar’s lighting system design and control software: Designer, or Toolbox.

Microwave sensor
Detects movement within the detection range allowing load
control in response to changes in room occupancy.
IR Receiver
Receives control and programming commands from a Helvar
infrared remote handset (available separately).

WARNING
Take special care
when bending springs
to install the unit.
Note: Order the SBB-A or SBB-AB surface mount boxes separately.
• Position the sensor so that the occupants of the room are normally inside the detection zone.
• Do not install the sensor within 1 m of any lighting, forced air heating, or ventilation equipment.
• Do not fix the sensor to an unstable or vibrating surface.
• Install the unit as far away as possible from the surface of metal objects.
• The detection pattern illustrated (see ‘Detection Pattern’ on page 1) is based on a mounting height of 2.8 m.
A lower mounting height will decrease the overall size of the detection zone.
Installation Notes
Installation
All dimensions in millimetres.
1. Install the unit: see ‘Connection and Fixing’ on page 2.
2a. Connect the DALI terminal blocks to the sockets located at the rear of the sensor.
2b. If required, connect the optional power supply. See ‘External Power Supply (Optional)’ on page 3.
3. Power the unit up.
4. After the lighting load switches on, by default it will switch off after 20 minutes of no movement detected.

You can use a Helvar infrared remote handset,
such as the 303 DIGIDIM Infrared Remote Control,
to send signals to the 313 Detector to:
– Recall lighting scenes 1–4.
– Adjust light levels.
– Store current level.
– Install preset levels for scenes 1–4.
Remote Control
Other Functions
Sensitivity
Adjust the sensitivity using Designer, or Toolbox (Helvar’s lighting system design and control software).
Note: On maximum sensitivity, the detector unit is extremely sensitive to movement and may detect through glass, thin walls or
partitions. If this causes a problem, reduce its sensitivity.
Adjusting On, Exit and Transition Time-Outs
The default time-outs for On, Exit and Transition can be altered using Designer, or Toolbox.
Check Connection to DALI Network
To make sure that the sensor is correctly connected the DALI network, use the Identify function in Designer, or Toolbox.
Using Designer and Toolbox Software
When using Designer, connect the PC to the lighting network via a Helvar router.
When using Toolbox, connect the PC to the lighting network via a Helvar serial or USB interface.
For information about Designer and Toolbox, visit www.helvar.com.

User Guide.
External Power Supply (Optional)
The following table gives the various 12 V to 24 V external power supply units that can be used,
as well as the sensor hardware revision needed for each of them. With some models, you must
make a wire link between the DALI negative terminal and the negative terminal of the external
power supply, as shown in the figure.
