INTRODUCTION


The work covered in this section is subject to all of the requirements in the General
Conditions of the Specifications. Contractor shall coordinate all of the work in this section
with all of the trades covered in othe
r sections of the specification to provide a complete
and operable system.


2.

EQUIPMENT QUALIFICATION


Products supplied shall be from a single manufacturer that has been continuously involved
in manufacturing of occupancy sensors for a minimum of five (5) y
ears. Mixing of
manufacturers shall not

be

allowed
.

Products shall be manufactured by an ISO 9002 certified manufacturing facility and shall
have defect rate of less than 1/3 of 1%.

IEC 60669

-
1 / CE / Rohs compliant

SYSTEM DESCRIPTION


The objective of
this section is to ensure the proper installation of the occupancy sensor
based lighting control system so that lighting is turned off
automatically if the daylight set
point level is reach, or after reasonable time delay when a room or

area is vacated by
the
last person to occupy said room or area.

The Occupancy Sensor system shall sense the presence of human activity within the
desired space and fully control the “On” / “Off” function of the lights.

Time Delay settings shall be factory set at 15 minutes a
nd the daylight set point 500 lux
for ceiling mount and 300 lux for wall corner

sensors
. This delay selection and the
brightness threshold are based on lamp life vs. energy savings and sensor performance.

To increase energy saving, in manual
-
on

mode t
he W
alk
-
Through mode is useful when a
room is momentarily occupied. If the person leaves the room within 30 seconds, the
sensor will turn the light off 3 minutes after the initial detection.



-

3

-

The Trigger Mode is another great feature available on
vacancy

sens
ors. This
technology

required to turn lights back on shortly after lights turned off

due to lack of motions. T
he
occupant has 30 seconds to be detected and re
-
trigger the sensor and
turn on

lights
automatically. If no detection
is

noticed within 30 sec, th
e occupant will need to manually
press the ON/OFF button to turn lights back ON.



Our sensors can provide audible alerts as a warning before the load turns OFF.


-

Audible
alert:

at 1 min, 30 sec, and 10 sec before time delay elapses the motion sensor
can

produce an audible sound for an extinction warning.

With

infrared

commissioning tool ,

lot of parameter

can be customized as t
he time delay,
t
he daylight set point,

sensor sensitivity,

daylight calibration,
t
he
walk
-
t
hrough

or
and the
re
-
trigger mode, the

audible a
lert
.



Installer, in accordance with manufacturer’s recommendation, shall determine final sensor
location. All sensors shall have adjustable factory calibrated sensitivity for maximum
performance.

The installing contractor shall be responsible
for a complete and functional system in
accordance with all applicable local and national codes.

The occupancy sensor based lighting control shall accommodate all conditions of space
utilization and all irregular work hours and habits.

Contractor shall war
rant all equipment furnished in accordance to this specification to be
undamaged, free of defects in materials and workmanship, and in conformance with
specifications. The supplier’s obligation shall include repair or replacement, and testing
without charg
e to the owner, all or any parts of equipment which are found to be
damaged, defective or non
-
conforming and returned to the supplier. The warranty shall
commence upon the owner's acceptance of the project. Warranty on labor shall be for a
minimum period o
f two (2) years.
