PIR Sensor
Detects movement within the detection range, allowing load control in response to changes in room occupancy.

The red LED flashes to indicate: Valid setting received (single flash of LED)
Identify active (LED flashes repeatedly)
DALI Connection
The DALI connection is made via DA+ and DA– terminals. The device is not polarity-sensitive.
IR Receiver and Remote Control
You can use the Helvar 303 Infrared Remote Control (available separately) to:
• recall lighting scenes 1–4;
• adjust light levels;
• store current level; and
• install preset levels for scenes 1–4.
Note: A different remote control unit (IR307) is used for 317 sensors of hardware rev. 1, and software version 5.40.
For instructions, see Installation Guide 7860287, issue 1.
High-Bay Presence/Absence Detector (317)
The 317 High-Bay PIR Presence/Absence Detector, in conjunction with a Helvar lighting control system, provides
automatic control of lighting loads in buildings and interior spaces with high ceilings. The 317 is typically installed in
warehouses and factories, and it is used in other applications where mounting heights are too high for standard sensors.
As with all the other Helvar ‘system’ sensors, the 317 is fully compatible with Helvar’s lighting systems and
configuration software, Designer and Toolbox. Once connected to a Helvar DALI network and lighting control system, the
software automatically detects the unit, which can then be programmed with the required functions.
Sensitivity
Adjust the sensitivity using Designer or Toolbox.
The factory default setting is 9 (maximum).
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.
The temperature difference between the detection target and the background must be at least 4°C.
Adjusting On, Exit and Transition Time-Outs
The default time-outs for On, Exit and Transition can be altered using Designer, or Toolbox.
Identify: Check Connection to DALI Network
To make sure that the sensor is correctly connected to the DALI network, use the Identify function in Designer or
Toolbox. The sensor’s status LED flashes repeatedly until Identify is cancelled.

Detection area
A lower mounting height
will decrease the overall
size of the detection zone.
Alignment marks
15 m
40 m
Alignment Marks
The sensor head has 4 alignment marks.
These marks correspond to the four outer passive
infrared sensors under the lens.
Use these marks to align with aisles and corridors to
ensure the best detection characteristics.

Detection Area Masking
Two adaptable clip-on shielding masks are supplied with the 317. Each can cover half of the sensor lens.
Lateral or radial strips can be cut out of the masks to customise the detection area.
Aisles/Corridors (lateral masks)
Cut the mask to make two lateral masks. This leaves a straight section of the lens uncovered.
The slots you cut out approximate to the levels of sensor coverage given in the following table:
Orientation and Sensitivity
If someone walks ‘across’ the detection area (not directly towards the centre of the sensor), the sensor range is greater
than if someone walks towards the centre of sensor (‘along’ the line between alignment marks).
Therefore, note the orientation of the sensor (as indicated by the alignment marks) when installing the sensors.
Small Areas (Radial Masks)
Cut semicircles out of the mask to make two radial masks. This leaves a circular section of the lens uncovered.
The ‘diameter numbers’ of the semicircles you cut out approximate to the levels of sensor coverage given in the table:

1. Connect the DALI connector to the socket located at the rear of the sensor.
2. Flush fixing: Insert the unit into the ceiling or wall (see Connection and Fixing: Flush Fixing); or
Surface mounting: Install the unit using the SBB-A surface back box (see Connection and Fixing: Surface Mounting).
3. Power the unit up.
4. Configure the unit using Designer or Toolbox.
5. If the load triggered by the sensor comes on, by default it will take 20 minutes (of no movement detected) for the
load to switch off.
Installation Notes
• Position the sensor so that the occupants of the room are normally inside the detection zone.
• Do not fix the sensor to an unstable or vibrating surface.
• Do not install the sensor within one metre of any lighting, forced air heating, or ventilation equipment.
• Consider the possible effects on infrared detector of layers of hot and cold air in large buildings.
Layers of cold or hot air can form in the upper part of large buildings, such as warehouses, due to a number of factors,
including the layout of the building, heating and ventilation systems, shelving system arrangements, roofing materials and
the weather. If the sensor is positioned in or above such a layer of air, the sensitivity of the sensor cannot be guaranteed.
