General Information
The DS840LSN is a microprocessor-based TriTech
Passive Infrared/Microwave Intrusion Detector.
Patented Passive Infrared and Microwave signal
processing provides excellent catch performance with
freedom from false alarms.

Mounting
3.1
Mounting Considerations
•
Never install the detector in an environment that
causes a constant alarm in one technology; it
should never be left to operate with the LEDs in a
constant flashing green, yellow, or red condition. A
detector with one technology in constant alarm will
cause an alarm output whenever the other
technology alarms. Good installations start with the
LEDs OFF when there is no target motion.
•
Point the unit away from outside traffic (for
example, roads, alleys, and parking lots).
The DS840LSN can communicate and connect to all
LSN Bus Systems.

locations
•
Eliminate interference from nearby outside
sources.
•
Avoid installations where rotating machines (such
as ceiling fans) are normally in operation within
the coverage pattern (see Figure 2).
Changes or modifications not expressly approved by

During walk testing, the LEDs light for the first
technology (microwave or PIR) and then light red to
indicate a detector alarm. The LEDs will not indicate

If the detector experiences a Microwave or PIR self-test
failure, it is in need of replacement.

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 three colored LEDs. The
edge of the pattern is determined by the first green
PIR activation of the LEDs (or the first red
activation if the yellow microwave LED activates
first).
Walk test from the opposite direction to determine
both boundaries.
While standing 3 m to 6 m (10 ft. to 20 ft.) from
the detector, slowly bring your arm up and into the
pattern to mark the lower boundary on PIR alarm.
Repeat from above for the upper boundary.
Enable Walk Test via the keypad.
The LEDs 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 3
colored LEDs. The edge of the microwave pattern
is determined by the first yellow, microwave
activation of the LEDs (or the first red activation if
the LEDs show green 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.
Do not adjust the microwave range higher
than required. Doing so will enable the
detector to catch movement outside of the
intended coverage pattern.
Figure 7: Microwave Range Adjustment

Establishing Microwave Coverage
Wait one minute after removing/replacing
the cover so the microwave portion of the
detector can settle. Wait at least ten
seconds between the following walk testing
procedures.
Walk Test
During the warm-up period, the LEDs will
flash red, yellow and green until the unit
stabilizes (approximately one to two
minutes) and has not registered movement
for two seconds. When the LEDs stop
flashing, the detector is ready to be tested.
With no motion in the protection area, the
LEDs should not be flashing. If the LEDs
are flashing, recheck the protection area for
disturbances affecting the microwave
(yellow) or PIR (green) technologies.
7.1
7.2
If the desired coverage cannot be achieved, try
angling the coverage pattern up or down to assure
the pattern is not aimed too high or low.
Walk test the unit from all directions to determine
all the pattern boundaries.
Verify Detector Coverage
The LEDs should be OFF before walk testing.
1. Walk test the unit from all directions to determine
the detection boundaries. A detector alarm is
signaled by the first red activation of the 3 colored
LEDs after an initial green or yellow activation.

Supervision Features
Supervision Features
The supervision features function as follows:
•
•
9.
•
•
PIR/Microwave: The complete circuit operation
of these subsystems is checked approximately
every 12 hours. If the PIR or microwave subsystem
fails, this will be communicated to the control
panel.
Default: The detector will default to PIR
technology protection if the microwave subsystem
fails.
EN | 7
10. Using Pet Immunity
The DS840LSN detector provides reasonable
protection from nuisance alarms caused by the
following sources:
•
One dog up to 27 kg (100 lbs.)
•
Up to 10 cats
•
Multiple small rodents, such as rats
•
Random flying birds
The Pet Filter is not a mirror mask. Use only
the supplied filter for pet applications.
Other Information
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.
Pattern Masking: The PIR coverage pattern may
be masked using masking tape or electrical tape on
the inside of the mirror.
To take full advantage of the Pet Immunity feature, the
following steps should be followed:
1. Add the Pet Filter to the mirror (included in the
hardware bag). See Figure 8.
Figure 8: Applying the Pet Filter
Many adhesives will either destroy the
mirror surface or leave enough residue
behind to degrade the coverage
performance. Be sure to clean the mirror
surface with a mild window cleaning
solution after masking removal.
Masking only eliminates the PIR portion of
the coverage and has no affect on the
microwave pattern.
Add the Pet Filter for pet applications only.
1 - Pet Filter
2 - Mirror Assembly
2. Mount the detector 2 m (6.5 ft.) high and adjust the
Mirror angle as in Section 6. Mirror Alignment.
3. Mount where the animals can not come within
1.8 m (6 ft.) of the detector by climbing on
furniture or other objects.
4. Adjust the microwave range for the minimum
acceptable coverage for the room in which the
detector is installed.
Pet immunity is only available when using
the filter provided with the detector. This
pet nuisance protection has not been
verified by Underwriters Laboratories, Inc
