GENERAL OPERATION
The LH-MT is the world’s first wall switch replacement
occupancy sensor to combine both ultrasonic (US) and
passive infrared (PIR) sensing. Hubbell Building Automation’s
self-adapting LH-MT addresses areas with complex environments that are difficult to control with single technology
sensors. The internal microprocessor analyzes the information
from both the US and PIR technologies and determines the
optimum setting to use in order to properly cover the space.
The “Intelligent software” algorithm determines, for example,
if the lights are staying on due to adjacent hallway traffic and
responds by adapting its program to compensate for the false
trigger and turns out the lights. The LH-MT is the ideal wall
switch replacement combining both superior minor motion
detection of US with excellent long-range major motion
detection of PIR.
Occupancy sensors have two tasks keeping the lights on while
the room is occupied and keeping the lights off when unoccu-
pied. Hubbell Building Automation’s continuously adapting
sensor technology eliminates manual sensitivity and timer
adjustments during installation and over the life of the
product. The self-adapting microprocessor constantly assures
maintenance free “Install and Forget” operation.
In addition, the LH-MT has its own built-in photocell, which
increases Energy Savings when engaged by preventing the
lights from turning on when there is sufficient natural light.
This feature is factory disabled and may be activated by the
installer.
Designed specifically to meet the challenges found in rooms
where tasks entails minor motion for long periods of time,
Hubbell Building Automation’s intelligent software reads the
environment and adapts to meet those specific challenges.
Should the room suddenly be reallocated into a copy room
with high traffic patterns, the intelligent software will adapt as
needed to provide the correct time out for the lights. Using
PIR sensing (high error immunity) with US (high sensitivity)
provides good performance. Conventional ceiling mounted
dual tech sensors use a simple formula for operation: BOTH
for ON, EITHER for KEEP ON. This method requires that
both sensors receive fixed-strength signals for ON or a single
fixed-level signal for KEEP ON. The LH-MT uses a more
sophisticated method called a composite signal where the

signal strengths are added together to form a composite sum.
The advantage of this method is that a weak PIR signal plus a
strong US signal will turn the lights on because the sum is
enough. The installer need not worry that the signal level be
balanced for reliable lights on. This technology eliminates
time consuming adjustments and callbacks.
