Ceiling PIR Detector (311)
The 311 Ceiling PIR Detector is a compact unit that
provides energy-saving functions in a DALI system. It
contains these sensors:
• Passive infrared detector (PIR)
• Infrared receiver
As a presence detector, the unit can turn the lights on when
a room is occupied, and off when the room is unoccupied.
The 311 is fully compatible with Helvar’s lighting system
design and control software: Designer, and Toolbox.
Detection Pattern

range, allowing load control in response to changes in
room occupancy.
• IP55 and cold environment (–30 °C) versions available.

Key Features
Installation
All versions of the Detector can be mounted into a ceiling
or wall void, or onto a solid surface using a back box.
The standard version (311) can be mounted onto Helvar’s
SBB-A back box, whereas the 311P and 311M versions
need to be mounted onto Helvar’s fully sealed SBB-P
back box to maintain the IP rating.
When mounting the 311P and 311M versions, the supplied
silicone gasket must always be used.
