These ceiling mount, 18 m (60 ft) panoramic PIR
Detectors use Motion Analyzer II processing to reduce
false alarms. The series consists of the:
• DS938Z Panoramic Detector
• ZX938Z Panoramic Detector with POPIT
Several unique self-test features, including Motion
Monitor, provide coverage integrity. Field replaceable
mirrored optics allow them to be mounted on ceilings
from 2.5 m to 6 m (8 ft to 18 ft) in height.
Functions
Motion Analyzer II Processing
Motion Analyzer II uses multiple thresholds and timing
windows to analyze timing, amplitude, duration, and
polarity of signals to make an alarm decision. It will
not alarm on extreme levels of thermal and
illumination disturbances caused by heaters and air
conditioners, hot and cold drafts, sunlight, lightning,
and moving headlights. Provides three sensitivity
settings.
PIR Supervision
PIR supervision provides trouble output in the event
that PIR circuitry fails.
Motion Monitor
Switch-selectable four or thirty day Motion Monitor
supervision timers provide the detector with the ability
to verify that there is a clear view of the protection
area and that it has not been blocked.
Test Features
Three externally visible high output alarm LEDs visible
from any angle, flash to indicate trouble condition.
Internal noise voltage test pins provide precise pattern
location and background disturbance evaluation using
a standard analog meter.
Certifications and approvals
These detectors have also been designed to meet the requirements of:
Europe
