HONEYWELL DT900 DUAL TEC, 90' x 80', wide area with anti-mask

DT900

The use of two technologies—microwave and PIR—and features

like anti-masking, vandal-resistant housing, large coverage patterns

and three microcontroller-based sensitivity modes, make the powerful

DT900 DUAL TEC sensors ideal for the harshest commercial and

industrial environments.

specifications

• Microcontroller-Based Dual Technology
Microwave and passive infrared (PIR) technologies, combined with

microcontroller-based advanced signal processing, provide excellent

detection while virtually eliminating false alarms and costly service calls.

• Sensor Sabotage Prevention
The DT900 Series uses Active Infrared for anti-masking to detect attempts

to mask the sensor. The patented look-down lens catches saboteurs who

try to disable the unit from below, while three different tamper switches

deter would-be criminals from physically damaging the sensor. The patented

INFORMER® function, designed primarily as a diagnostic tool, monitors for

sensor blockage and can help identify a sabotage situation.

• Queue Logic Event Processing
The microcontroller in the DT900 converts all incoming microwave and

PIR signals from analog-to-digital format. If the signal is determined to

be valid it enters the Queue Logic Event Process. This process stores

the valid signals within a moving window of time, keeping up to eight

events for each signal type. Based on the First In First Out (FIFO) concept,

Queue Logic requires a sophisticated on-board microcontroller to make

advanced calculations for qualifying a sequence of events as an actual alarm.

• Self-Test and Continuous
Supervision for High Reliability This industrial-grade sensor performs

multiple levels of supervision. The INFORMER function checks each

technology continuously. The microcontroller conducts a self-test of the

sensor’s functions at regular intervals, and reports any trouble using the

on-board trouble relay.

• Designed for Harsh Environments
Vandal resistant housing combined with a zero clearance bug guard make

the DT-900 series ideal for commercial and industrial applications such as

warehouses, large retail facilities, manufacturing sites and schools.

• Self-Adjusting Thresholds
The on-board microcontroller automatically adjusts the microwave and PIR

thresholds to compensate for environmental disturbances not related to actual

intrusion events. True temperature compensation continually optimizes the

performance of the PIR to account for changes in room temperature.

Environmental noise compensation keeps common environmental disturbances

such as fluorescent lights from causing the microwave to false alarm.

• Technology

– PIR for intrusion detection

– Microwave for intrusion detection

– Active infrared for anti-masking (DT900 and DT906 

• Digital Fluorescent Light Filter
Digital filter virtually eliminates interference caused by fluorescent lighting.

• Three Microcontroller-based Sensitivity Modes
Sensor sensitivity can be set to high for fastest capture, to normal, or to low

for maximum false alarm immunity in harsh environments.

• Sensitivity
Two to four steps within field-of-view, depending on sensitivity setting selected.

• Zero Clearance Bug Guard
The bug guard provides zero clearance, protecting the pyro chamber from

insects that can cause false alarms.

• Small Animal Immunity
Immune to small animals commonly found in commercial conditions (birds, rodents, snakes).

Installer-Friendly Design
Designed with the installer in mind, the DT900 contains a large wiring

space, protective clear plastic covers over the circuit boards to prevent

damage, two end-of-line terminals, flashed over LEDs visible at great

distance, a fast-install wall mounting plate for the included swivel mounting

bracket and easy vertical and horizontal adjustment.

• Mirror Optics For Long Range
The DT900 series utilizes custom designed mirror optics to provide

effective capture at long range. Each model is easily selectable between two ranges.

• LED Diagnostics
The LEDs will display codes to indicate an anti-masking condition, INFORMER

condition, trouble condition, and recallable codes to indicate INFORMER results

and whether or not there was a self-test failure.

• Advanced Commercial/Industrial Features
In addition to anti-masking (DT900/DT906), the DT900 Series has command input

for initiating a self-test remotely, has CENELEC two wire input options and

has a remote LED enable input.
