u Up to 6.1 m (20 ft) mounting height

u Fully adjustable optics for coverage integrity and

customization

u Hinged chassis and base plate for easy installation

The ceiling mount DS939 PIR Detectors provide up to

16.4 m (54 ft) panoramic coverage pattern and can be
mounted on ceilings as high as 6.1 m (20 ft). With
three separate PIR sections that are fully adjustable,
the DS939 detectors provide coverage integrity at all
mounting heights, plus the ability to customize the
coverage for specific areas. The DS939 detectors use
several patented processing techniques to provide
excellent catch performance with freedom from false
alarms.

Functions

Signal Processing

The DS939 detectors use passive infrared
technologies to provide an alarm condition when the
field of protection is activated. Alarm signals must
meet the signaling requirements to activate an alarm.

u High efficiency LED and light pipe system for easy

walk testing

u First Step Processing (FSP)

Test Features

• High efficiency LED and light-pipe system provide
walk test indication that is easily viewable from any
angle and at any mounting height.

• Alarm memory feature allows detector to latch the
alarm LED to aid in response.

• Remote LED walk-test control allows the LED to be
enabled or disabled using a switched input without
accessing the detector.

First Step Processing

First Step Processing (FSP) allows virtually instant
response to human targets without sacrificing false
alarm immunity to other sources. By adjusting its
sensitivity based upon signal amplitude, polarity, slope
and timing, FSP eliminates the need for the installer to
select the sensitivity level for the application. Each
sensor is processed individually and both must agree
there is an alarm before the alarm relay is activated.

Installation/configuration notes

The maximum range of the detector depends on the
mounting height and the vertical adjustment of the PIR
coverage pattern. In areas where part of the area
needs a targeted coverage, the optical modules can be
adjusted for the correct coverage.
A masking kit containing two 120° and two 90° masks
is included to allow masking unwanted areas. Apply
the masks to the outside of the detector. With the
supplied masks, you can mask 90°, 120°, 180°, 210°,
240°, or 330°.

Coverage Information

For UL, ULC applications, provides up to 7.0 m (23 ft)
radius, 14.0 m (46 ft) diameter 360° coverage when
mounted up to 6.1 m (20 ft).
For EN50131 applications, provides up to 7.0 m (23 ft)
radius, 14.0 m (46 ft) diameter 360° coverage when
mounted up to 5.2 m (17 ft).
For CCC applications, provides up to 8.2 m (27 ft)
radius, 16.4 m (54 ft) diameter 360° coverage when
mounted up to 4.9 m (16 ft).
Pattern consists of 69 zones in 21 barriers. The
barriers are grouped into three groups of seven
barriers each. Each group has vertical adjustment for
customized coverage.

Mounting Considerations

The mounting height range is from 2.4 m to 6.1 m (8 ft
to 20 ft).
These detectors can be mounted directly on the
ceiling or on a standard 9 cm (3.5 in.) rectangular
electrical box.
