DS720i Series Long-Range

TriTech

Detectors

The wall or ceiling mount DS720i Se-

ries TriTech detectors provide instal-

lation flexibility using field-

replaceable mirror arrays with three

different coverage patterns:

• 300 ft by 15 ft (91 m by 4.6 m),

• 120 ft by 25 ft (37 m by 8 m), or

• 90 ft by 70 ft (27 m by 21 m).

The combination of passive-infrared (PIR) detection, micro-

wave detection, and advanced signal processing techniques al-

lows TriTech detectors to rapidly respond to human targets

without triggering false alarms from other sources. Motion

monitor supervision and anti-masking protection ensure that

the detector's view of the coverage area remains clear and un-

obstructed.

Series Features

•Supervised microwave and PIR

• Anti-masking with spray detect

• Motion monitor supervision

• Motion Analyzer II

• Field-replaceable mirror arrays

Functions

Alarm memory

In multiple unit applications, the control panel switches volt-

age to the unit that first sent an alarm signal which latches the

alarm LED on that unit.

Signal processing

These detectors use passive infrared (PIR) and microwave

technologies to signal an alarm when the fields of protection of

both technologies are activated at the same time. The PIR and

microwave sensitivities are adjustable.

Motion Analyzer II PIR signal processing uses multiple

thresholds and timing windows to analyze timing, amplitude,

duration, and polarity of signals to make an alarm decision.

Extreme levels of thermal and illumination disturbances

caused by hot and cold drafts, sunlight, or lightning do not

cause an alarm. Two sensitivity settings are provided.

Microwave signal processing uses pattern recognition circuit-

ry to identify and ignore repetitive false alarm sources. Adap-

tive processing adjusts to background disturbances to reduce

false alarms without sacrificing the ability to respond to an in-

truder.

Test features

The LED flashes to indicate a trouble condition.

A standard analog meter connects to dual-channel test pins

within the detector to provide precise pattern location and to

measure noise voltage for background disturbance evaluation.

The walk test LED can be activated remotely by a control panel

command.

Supervised microwave and PIR

The microwave circuit is fully supervised. If the microwave

subsystem fails, the PIR subsystem provides single technology

Anti-masking with spray detect The PIR anti-masking feature detects objects placed to block the detector's field of view or materials sprayed on the detector's lens area. The size of the anti-mask feature's field of view can be selected as either standard or large.
