2.0 Installation Considerations
NOTE: The DS950 is not recommended for installations containing
pets or small animals. Use the DS820 or DS835 for such
installations.
• Never install the detector in an environment that causes an alarm
condition in one technology. Good installations start with the LED
OFF when there is no target motion. It should never be left to
operate with the tri-color LED in a constant or intermittent green,
yellow, or red condition.
• Point the unit away from outside traffic (roads/alleys).
NOTE: Microwave energy will pass through glass and most
common non-metallic construction walls.
• Avoid installations where rotating machines (e.g. ceiling fans)
are normally in operation within the coverage pattern. Point the
unit away from glass exposed to the outdoors and objects that
may change temperature rapidly.
NOTE: The PIR detector will react to objects rapidly changing
temperature within its field-of-view.
• Eliminate interference from nearby outside sources.
3.0 Mounting
• Select a location likely to intercept an intruder moving across the
coverage pattern. The surface should be solid and vibration-
free. Mounting height range is 6 to 8 feet (1.8 to 2.4 m).
Recommended mounting height is 7.5 feet (2.3 m).
• Remove the cover. Insert a flathead screwdriver into the locking
tab hole at the bottom front of the detector. Pull the cover up and
forward.

• Terminals 1 (–) & 2 (+): Voltage limits are 9 to 15 VDC. Use no
smaller than #22 AWG (0.8mm) wire pair between the detector
and the power source.
• Terminals 3, 4, & 5: Alarm relay (reed) contacts rated 3 W,
125 mA, 28 VDC maximum for DC resistive loads and protected
by a 4.7 Ω, 0.5 W resistor in the common "C" leg of the relay. Use
Terminals 4 and 5 for Normally Closed circuits.
NOTE: Do not use with capacitive or inductive loads.
• Terminals 6 & 7: Tamper contacts rated at 28 VDC, 125 mA.
• Terminal 8: Memory. Refer to Section 6.0 Feature Selection.
• Terminal 9: Trouble. Solid State output.
NOTE: Plug the wire entrance hole with the foam plug provided
after all wiring connections have been made.
5.0 LED Operation
The chart below shows tri-color LEDs the detector uses to indicate
the alarm and supervision trouble conditions.
LED CAUSE
Steady red Unit alarm
Steady yellow Microwave activation (walk test)
Steady green PIR activation (walk test)
Flashing red Warm-up period after power-up
Flashing red (2 pulse sequence) Motion monitor time-out
Flashing red (3 pulse sequence) Anti-mask detection
Flashing red (4 pulse sequence) MW or PIR self-test failure
Flashing red 2 - 4 = The LED flashes 2-4 times a cycle.
NOTE: During walk testing, the LED will light for the first technology
(microwave or PIR) and then light red to indicate a detector
alarm. The LED will not indicate activation of the second
technology by lighting its color.
6.0 Feature Selection
6.1 LEDOn/Off Pins
The ON position allows operation of the tri-color LED. If
LED indication is not desired after setup and walk tests are completed,
place in the OFF position. The OFF position does not prevent the LED
from indicating supervision trouble conditions.
6.2 Memory Operation and Microwave Inhibit
To use the alarm memory function, cut the Memory Jumper (after
walk testing). When this jumper is cut, the Microwave Inhibit function
is also activated. This eliminates microwave transmissions during
disarmed periods.
To supply voltage, connect a switch between Terminals 2 and 8 on
the detector’s T-strip as shown here:
12345678 9
NOTE: If switched voltage (between 9 and 15 volts) is supplied
from another source, such as an alarm panel, then wiring
must also be provided from Terminal 1 of the detector to the
negative (-) side of the alternate source.
When voltage is applied to Terminal 8, any stored alarm is cleared
from memory and it is ready to store the next alarm.
When voltage is removed from Terminal 8 (disarmed condition), the
tri-color LED is enabled, and a stored alarm will cause the tri-color
LED to turn ON red continuously. If there is no stored alarm, the tri-
color LED and relay will respond to PIR only; they will activate only
during a present alarm.
NOTE: The Motion Monitor and Anti-Mask pins must
be in the OFF position in order for the
Microwave Inhibit feature to work.
6.3 PIR Sensitivity Selection Pins
For selection, place the plug across the pins marked STD for Standard
or INT for Intermediate mode.
• Standard Sensitivity: The recommended setting for maximum
false alarm immunity. Tolerates environmental extremes on this
setting.
•Intermediate Sensitivity: The recommended setting for any
location where an intruder is expected to cover only a small portion
of the protected area. Tolerates normal environments on this
setting. This setting will improve
your intruder catch performance.
6.4 Motion Monitor/Anti-Mask
Pins
By enabling Motion Monitor and the Anti-Mask feature with the selection
pins, a choice of Off or 1 day or 30 days may be chosen for Motion
Monitor.
IMPORTANT
If 1-day Motion Monitor is selected, the memory
feature must be enabled by cutting the memory
jumper. The Motion monitor timer will be suspended
when the detector is in night (armed) mode.
To suspend the 1-day motion monitor timer when the control panel is
armed, apply a switched voltage to Terminal 8 as shown in the
beginning of Section 6. This will prevent the motion monitor from
timing out when no movement is anticipated. When the switched
voltage is removed from Terminal 8, the motion monitor timer will
continue to count down until motion is detected.

If the time period selected has elapsed from the last detector alarm,
a supervision trouble condition will be signaled. Refer to the
Supervision Features section for more information.
NOTE: If this feature has been enabled, and you wish to use the
Memory feature, the Microwave Inhibit feature will be disabled.
6.5 Trouble Memory
Short the Trouble Memory contacts with a flathead screwdriver. The
LED will indicate the last trouble condition that occurred.
7.0 Setup and Walk Tests
Select the vertical starting angle from the following chart:

-5°-6°
-9° -7°
DS950
To adjust the vertical starting angle for the desired mounting height
and range, loosen the vertical adjust screw and slide the board up, to
point the angle down. Note the settings on the vertical adjust scale.
• Place the LED plug in the ON position and replace the cover.
7.1 Establishing PIR Pattern Coverage
• Turn the Microwave range adjust to minimum.
• Replace the cover and snap it into place. This will close the
tamper switch.
•Wait two minutes minimum after applying power to start walk
tests.
NOTE: During the warm-up period, the tri-color LED will flash red
until the unit has stabilized (approximately 1 to 2 minutes)
and has seen no movement for two seconds. When the tri-
color LED stops flashing, the detector is ready to be tested.
With no motion in the protection area, the tri-color LED should
be OFF. If the LED is on, re-check the protection area for
disturbances affecting the microwave or PIR technologies.
• Walk test across the pattern at its farthest edge, then several
times closer to the detector. Start walking from outside of the
intended protection area, and observe the tri-color LED. The edge
of the pattern is determined by the first green, PIR activation of
the LED (or the first red activation if the yellow microwave LED
activates first).
• Walk test from the opposite direction to determine both
boundaries. The center of the pattern should be pointed toward
the center of the intended protection area.
NOTE: The pattern may be moved ±10° horizontally by rotating the
lens window left or right.
• Slowly bring your arm up and into the pattern to mark the lower
boundary on PIR alarm. Perform this task at 10 to 20 ft. (3 to 6 m)
from the unit. Repeat from above for the upper boundary. The
center of the pattern should not be tilted upward.
NOTE: If desired coverage cannot be achieved, try angling the
coverage pattern up or down to assure the pattern is not
aimed too high or low. The angle of the PIR pattern may be
vertically positioned between -10° and +2° by loosening the
Vertical Adjust screw and sliding the circuit board up or down.
Moving the board up will angle the pattern downward.
• Tighten the screw snug when positioning is completed.
7.2 Establishing Microwave Coverage
NOTE: It is important to wait one minute after removing/replacing
the cover so the microwave portion of the detector can settle,
and to wait at least ten seconds between the following walk
testing procedures.
• The tri-color LED should be OFF before walk testing.
• Walk test across the pattern at the intended coverage’s farthest
end. Start walking from outside the intended protection area and
observe the tri-color LED. The edge of the microwave pattern is
determined by the first yellow, microwave activation of the LED
(or the first red activation if the green PIR LED activates first).
• If adequate range can not be reached, increase the Microwave
Range Adjust slightly. Continue walk testing (waiting one minute
after removing/replacing the cover) and adjusting the range until
the farthest edge of desired coverage has been accurately placed.
NOTE: Do not adjust the microwave range higher than required.
Doing so will enable the detector to catch movement outside
of the intended coverage pattern.
• Walk test the unit from all directions to determine all the Microwave
pattern boundaries. Wait at least ten seconds between walk
tests.
7.3 Establishing Detector Coverage
• The tri-color LED should be OFF before walk testing.
• Walk test the unit from all directions to determine the detection
boundaries. A detector alarm is signaled by the first red activation
of the tri-color LED after an initial green or yellow activation.
8.0 Meter Tests
A 20,000 Ω/V (or greater) analog DC VOM is recommended. Set the
meter scale for 5 VDC (Use of the TC6000 is recommended, but is
not essential for meter use. Either outside connector pin of the TC6000
may be used for common.).
8.1 PIR Meter Readings
• Connect the meter to the PIR Noise Voltage Pins.
• With no target motion in the pattern, read the voltage.
NOTE: The base reference level for PIR background noise is
approximately 1 VDC. Installations in quiet environments,
therefore, should result in a steady meter reading between
0.9 VDC and 1.1 VDC.
• Walk test across the farthest edge of the coverage pattern. Make
sure the detector’s cover is on.
NOTE: Voltage changes greater than +0.75 VDC from the reference
level during walk tests are desirable. If changes are less
than 0.75 VDC, the detector may fail to respond at this far of
a distance if the temperature difference between the intruder
and the background is minimal. Try adjusting the unit up
and down to maximize the voltage change during walk tests.
• Turn on all heating/cooling sources that will be in operation during
times of protection. Stand away from the unit and outside the
protection pattern, then monitor background noise for at least
three minutes.
NOTE: Readings should not deviate more than 0.15 VDC from the
reference level. If they do, eliminate the cause or reposition
the pattern (observe readings while turning on and turning
off these sources as well as during the three minute interval).

8.2 Microwave Meter Readings
• Connect the meter to the Microwave (μw) Noise Voltage Pins.
• With no target motion in the pattern, read the voltage. The
background noise voltage should be steady, and should not
exceed 0.75 VDC. If it does, the cause of the disturbance should
be found and eliminated.
NOTE: Remember that microwaves penetrate non-metallic
surfaces. Movement on the other side of walls and doors
viewed by the detector could cause unexpected background
noise readings.
9.0 Supervision Features
The supervision features function as follows:
•PIR / Microwave: The complete circuit operation of these
subsystems is checked approximately every 12 hours. If the PIR
or microwave subsystems fail, the tri-color LED will flash red
four times per cycle and the unit should be replaced.
•Default: If the microwave subsystem fails, the detector will default
to PIR technology protection. The PIR signal sensitivity will
automatically change from INT to STD.
•Trouble Clear: An intrusion alarm will reset most existing
supervision trouble conditions. There must be at least ten
seconds of no activity (no alarm) prior to the detector alarm. Self
Test failures will not be cleared; the detector must be replaced.
•Anti-masking: When enabled, the detector will indicate an Anti-
mask supervision trouble condition if a microwave reflective
material (e.g. metal, most plastics, etc.) is placed within one foot
of the detector. This feature can be used to prevent intentional
and accidental masking of the face of the detector. It is enabled
or disabled using the Motion Monitor and Anti-mask Pins.
NOTE: The anti-masking feature may interpret removal and/or
replacement of the cover as an attempt to mask the detector
and may signal a supervision trouble condition. If this should
occur, reset the detector by removing and then re-applying
its power. The trouble condition will also be reset by the next
detector alarm after a 10 second period of no alarms from
either technology.
•Motion Monitor Supervision: This feature verifies that each
technology has a clear view of the detection area. When selected,
a supervision timer is activated which gives the detector the ability
to indicate a supervision trouble condition if the time selected by
the pins has elapsed since the last detector alarm.
If the detector does not see a detector alarm within the selected
time period, the tri-color LED will flash red two times to indicate
a supervision trouble condition and the Trouble output will
activate.
If the detector is set for 1-day motion monitor supervision, the motion
monitor timer is only active when there is no voltage applied to
terminal 8 of the detector. See Section 7.0.
10.0 Maintenance
At least once a year, the range and coverage should be verified. To
ensure continual daily operation, the end user should be instructed
to walk through the far end of the coverage pattern. This ensures an
alarm output prior to arming the system.
11.0 Coverage Pattern
The DS950 has a standard broad coverage pattern or an optional
long-range coverage pattern. The protected coverage area is where
the microwave and PIR patterns overlap.
An optional Look Down lens is located under the detector. This
lens must be unmasked before it is operational. Use caution to
remove the black mask only. Do not attempt to remove the white
lens assembly. The Look Down lens is not recommended for
installations containing pets or small animals. The Look Down
zone is shown in black on the Coverage Pattern drawings.
