The ISM-BLD1 TriTech® Detectors use a combination of
passive infrared (PIR) and microwave detection
technologies with advanced signal processing. These
unobtrusive detectors are simple to install and do not need
field adjustments.
These detectors are available in three frequencies:

Functions
Advanced Signal Processing
Adaptive processing adjusts to background disturbances,
reducing false alarms without sacrificing intruder detection.
First Step Processing (FSP) almost instantly responds to
human targets without producing false alarms from other
sources. FSP adjusts the detector's sensitivity based on
signal amplitude, polarity, slope, and timing. This eliminates
the need for the installer to select the sensitivity level. Each
sensor (PIR and microwave) processes signals individually,
and both sensors must agree there is an alarm before the
alarm relay activates.
Test Features
An externally-visible, tricolor (blue, yellow, green) alarm
LED (light-emitting diode) indicates each sensor's status.
Supervised Microwave
The microwave circuit is fully-supervised. If the microwave
subsystem fails, the PIR subsystem provides single
technology coverage.
Draft and Insect Immunity
The sealed optical chamber prevents drafts and insects
from affecting the detector.
Temperature Compensation
The detector adjusts its sensitivity to maintain its ability to
identify human intruders at critical temperatures.
