NEWLEC DALI OCCUPANCY DETECTOR FEEDBACK COLOURS AND FLASH STATUS
The Newlec DALI Occupancy Detector flashes several feedback colours via its LED to let you know what state it is in.
The following table indicates the states that it is showing after installation.
CALCULATING MAXIMUM RATIOS OF DALI OCCUPANCY DETECTORS TO BALLASTS IN A SINGLE NETWORK
Each Newlec DALI Occupancy Detector is capable of running 64 ballasts (although in reality that will not be sensible practice).
In order to calculate the maximum numbers of Occupancy Detectors and luminaires that can be on the same network, use the
following equation.
180 - (Lx2)
14
Where L = number of DALI luminaires
Worked Example 1
20 ballasts
For example 20 ballasts x 2 =40
180-40 = 140
140 = 10
14
Therefore maximum 10 detectors for 20 ballasts
POSITIONING OF THE DETECTOR
CAREFUL POSITIONING IS ESSENTIAL TO OBTAIN OPTIMUM PERFORMANCE
Use the detection range to determine a suitable location for the sensor. When locating the position of the units, ensure the sensor is
not subjected to bright or direct sunlight or in areas with high reflective surfaces. Do not site units on a vibrating surface, or near forced
air heating and ventilation. They should not be placed within 1 metre of the load. Sensors work when objects move across their field of
view. Position the sensor where people will be detected walking across the zones rather than towards the zones identified in diagram 1.
Adjust sensitivity to suit the area that the sensor has been installed in.
MODE
PIR COLOUR
STATE
PRESENCE
Lights OFF
No Flash
No flashes at the Occupancy Detector indicates no detection and lights will be OFF. There are no absence wall switches involved in this circuit.
PRESENCE
Lights ON
When operating in normal presence mode sensor LED blinks
BLUE
when there is presence detection and presence detected.
PRESENCE
OFF by Remote
In presence mode even if lights are switched off by Remote Control the sensor will flash
WHITE
(even if presence not detected i.e. no one is in
the room). This is to let you know the system has been switched off by remote control.
ABSENCE
Lights ON
If there are wall switches in this circuit wired into the A A position and the wall switch is operated, the LEDS on the sensor will blink
BLUE
then
RED
to indicate presence detected and absence mode is set.
ABSENCE
Lights OFF
Sensor continues to blink
RED
with lights off to indicate sensor is in absence mode (even if presence not detected. i.e. no one is in the room).
If lights are switched off by Remote control and are in absence mode the sensor will also flash
RED
(even if presence not detected).
CORRIDOR
Option
In corridor option a greenish
YELLOW
flash will indicate presence detected and in corridor option.
CORRIDOR Option
(Hibernation)
Occupancy Detector is in Corridor Option and two
WHITE
flashes indicates it has been switched off completely by remote (Hibernation).
When the remote ON/OFF button is re-pressed the Occupancy Detector will resume in corridor mode.
Remote Button
Press
When any button is pressed on the Remote Control a green flash confirms acceptance at the Occupancy Detector.
(Note
GREEN
flashes need to be counted when Selecting Room and Corridor Options- see Table X on the Remote Control Instructions).

IMPORTANT NOTICE
All wiring should be carried out by a competent person or a qualified electrician and should be fitted to IEE 17th Edition Wiring regulations
BS7671:2008. The circuit should be isolated before carrying out any work. Failure to adhere to the instructions will invalidate the warranty.

Worked Example 2
40 ballasts
40 ballasts x 2 =80
180-80 = 100
100 = 7 (rounded up)
14
Therefore maximum 7 detectors for 40 ballasts
