8 Coverage
•

360° by 60 ft. (18.3 m) diameter coverage when mounted on 8 to 18 ft
(2.4 to 5.5 m) high ceilings.

•

The coverage pattern consists of 64 zones grouped into 16 barriers,
with one additional zone looking straight down from the unit
(sabotage). Each barrier is 30 ft (9.2 m) long and 4.4 ft. (1.3 m) wide
at 30 ft (9.2 m).

•

The DS9382 comes with a choice of two optical modules. Refer to
Section 5.1 to determine the best module for on ceiling height.
F.01U.263.663 | 04 | 2013.04 | 11

If the time period selected has elapsed from the last alarm, the LED will
ﬂash two times and the Trouble Output will activate.

1 Overview

Setting the Motion Monitor timer to shorter periods can be used to force a
protection walk test of remotely located zones.
It is recommended that the 30 day timer be selected. This veriﬁes that
the unit is operational and avoids nuisance trouble conditions caused by
holidays, vacations, etc.

The DS938Z is a high performance passive infrared intrusion detector.
It is equipped with advanced PIR detection and supervision circuits and
is designed to provide an alarm condition upon detection of an intruder
passing through its area of coverage.
Employing balanced dual-opposed sensing elements, the DS938Z passive
infrared (PIR) detector makes use of the fact that all objects give off (emit)
infrared energy, and that the warmer an object is, the greater the amount
of infrared energy given off. The DS938Z uses PIR receiver technology
designed to detect the change in infrared energy caused when a target of a
different temperature from a stable background passes through its ﬁeld of
coverage.

7 Optical Module
7.1 Optical Module Masking
Peel-off masks are provided with the unit for each segment of the
optical module to allow for customized coverage, or to block out areas
of objects that may cause thermal disturbances. The mask is selfadhesive and pre-cut in the shape of the optical module.
The location of the zone to be masked depends on the position of the
detector. Therefore, determine the mirror surface to be masked before
removing the mirror from the detector.
To block out a particular zone or group of zones, peel off a section of
the mask that corresponds to the appropriate zone, and stick it on the
mirror segment. Before attempting any masking, be sure the chosen
mirror surface is the correct one. Refer to Figure 7.1 to identify mirror
segments and zones.

The coverage pattern consists of sensor zones arranged to form a circular
coverage pattern.
Using Motion Analyzer II circuitry, the detector must ﬁrst see a change
in infrared energy in one zone followed by a change of energy in the
remaining zone. Therefore, disturbances that occur in only one ﬁnger do
not constitute motion and are ignored. This “catch sensitivity” may be
changed in the ﬁeld by the installer to provide the degree of sensitivity
required by the installation.
Self-test and supervision circuits provide reliable operation in a variety of
installation environments. The result is a highly advanced detector offering
superior performance with freedom from false alarms.
Specifications

NOTICE!
When disabling the look-down segment, do not mask segment 5
directly as this will disable the entire detector. Instead, mask the
segment on the dome directly below segment 5.

2 Mounting

6.2 False Alarm Prevention

Select a location likely to intercept an intruder moving beneath and across
the coverage pattern. Refer to Figure 2.1. Recommended mounting height
range is 8 to 18 feet (2.4 to 5.5 m).

Turn on all heating and cooling sources that would normally be in
operation during times of protection. Stand away from the unit and
outside the coverage pattern, then monitor the background noise for at
least three minutes.

The surface should be solid and vibration-free. (i.e. Drop tiles should
be secured if the area above the tiles is used as an air return for HVAC
systems).

Optical module

The DS938Z performs several supervision features that, combined with
the advanced motion detection capabilities of the detector, provide
an extremely high level of security. A supervision trouble condition is
indicated at the detector by the Alarm/Test LED (see the Supervision
Display Chart).
•

The LED indicates the cause of the supervision trouble using coded
pulses. The supervision trouble signal activates the Trouble Output
available at terminal 8, which should be connected to a 24-hour zone.

The supervision features function as follows:

Figure 2.2: Opening cover

NOTICE!
Slightly rock the enclosure side-to-side during removal to overcome the
friction caused by the base-to-enclosure terminal pins.

2. Open the cover by turning counterclockwise.
3. Route wiring as necessary to the rear of the base and through the
center hole. Refer to Figure 2.3.

A minimum voltage change of 1.0 VDC from the reference level is required
in the wintertime when the background temperature is cool. This will make
up for summertime, when the background is warmer. If testing the unit in
the summertime, the minimum recommended voltage change is 0.75 VDC.

1. Remove the base from the enclosure by pressing the two enclosure
release tabs inward while lifting the enclosure away from the base.
Refer to Figure 2.2.

the Trouble Output will activate.
Motion Monitor Supervision: This feature veriﬁes that the detector has a
clear view of the detection area and has not been blocked. When selected
using switches S4 and S5, a supervision timer is activated. A trouble
condition will be indicated if the detector has not alarmed at least once
during the selected time period (this feature can be disabled by placing
both switches in the Off position). The time period selected should be
long enough to allow adequate time for holiday weekends.
Refer to Section 4.0 Feature Selection for proper switch settings.

NOTICE!
The use of a Sonalert type device (sounder) will provide an audible tone
during the time the unit is in alarm. Of the three available connector
pins, the center pin is positive (+) with respect to either outside pin
(outside pins are common (-)).
Use of the sounder is intended only as an aid for walk testing during
installation.

CAUTION!
Be sure all wiring is unpowered (de-energized) before routing.

NOTICE!
Walk testing should be done across the coverage pattern as shown.
Figure 2.3: Overview

6. The edge of the coverage pattern is determined when the Alarm/Test
LED indicator (and optional Sonalert®, if installed) ﬁrst turns on.
7. Walk test the unit from all directions to determine the boundaries.

4. Firmly mount the base. Depending on local regulations, the base may
be directly surface mounted using anchors, mollies, or wing-nuts, or
may be mounted to standard 4-inch octagonal or square electrical
boxes.

8. After completion of the walk tests, remove the Sonalert® (if installed).
NOTICE!
The DS938Z base will not completely cover a 4-inch square box. Where
aesthetics are important, a 4-inch octagonal box is recommended.

6 Final Tests
6.1 Noise Measurement

NOTICE!
Mounting to removable ceiling tiles is not recommended unless a
sandwich is made of the base, ceiling tile, and a back plate behind the
tile. Covers used for 4-inch octagonal and square boxes make a suitable
back plate (when used with bolts and wing nuts, as an example).

NOTICE!
Meter readings are very important in determining background
disturbance levels and catch margin sensitivity.

1. Connect a 20,000 ohm/volt (or greater) DC VOM to the Noise Voltage
connector using the TC6000 as shown. Set meter scale for about 3.0
VDC.
2. The base reference level for reading background noise or target
voltages is approximately 2.0 VDC. Installations in quiet environments,
therefore, will result in a steady meter reading between 1.9 and 2.1
VDC. Look for areas and sources of thermal disturbances if the meter
ﬂuctuates greatly.

3 Wiring
CAUTION!
Only apply power after all connections have been made and inspected.
Do not coil excess wiring inside detector. Use no smaller than #22
AWG (0.8 mm) wire in the terminal strip.

•

Standard Sensitivity: Tolerates environment extremes on this setting,
but requires the largest amount of intruder motion to achieve an alarm.

•

Intermediate Sensitivity: The recommended setting for most
installations. Use in locations where an intruder is expected to
cover only a small portion of the protected area. Tolerates normal
environments on this setting. The detector is shipped in Intermediate
Sensitivity mode.

•

High Sensitivity: The setting for fast response to intruder signals. For
use only in extremely quiet environments where ceiling drafts, and
thermal and illumination transients are not anticipated.

5 Setup and Walk Testing
1. Attach a TC6000 Test Cord to the Noise Voltage terminals. Since the
outside terminals are common, polarity is not important and the black
lead may be toward or away from the optical module.
2. Attach a Sonalert to the sounder pins at this time if one will be used
during walk testing.

4.2 Sensitivity Selection
Sensitivity modes depend on the type of coverage desired and the
installation environment.
