SRDT-15 FEATURES
A new generation of professional
movement spread spectrum analyzing PIR
& MW detectors
• Dual element PYRO sensor and hard lens for
outstanding detection performance and
elimination of false alarms
• Microwave detection based on Doppler concept
• Unique Microwave Motion Sensor Module with
microstrip patch antenna
• VLSI based electronics with movement speed
spectrum analysis
• AND & OR alarm signal selection
• Height installation calibrations free
• User-friendly installation with or w/o swivel
bracket
• 2-way Microwave sensitivity adjustment
• 2-way PIR sensitivity adjustment
• BI directional temperature compensation
• Environmental immunity
The SRDT-15 is a combination of PIR & MW
detectors, providing protection from intruders by
PYRO sensor element and MW (based on Doppler
concept)
Using micro controller for PIR & MW signal
analyzing, with special ASIC technology for PIR
pulse processing, assure “false alarm free”
operation
MOUNTING THE DETECTOR
Choose a location most likely to intercept an
intruder (Our recommendation is a corner
installation) See detection pattern in Fig : 5, 6
The dual-element high quality sensor detects
motion crossing the beam; it is slightly less
sensitive detecting motion toward the detector
The SRDT-15 performs best when provided with
a constant and stable environment
NOTE: recommended installation height is 2 1m
(option: 1 5m to 3 0m)

FIG. 1 - REMOVAL OF FRONT COVER
1 To remove the front cover, insert a flat
screwdriver in the slot between the front and
the bottom above the holding screw hole and
push gently, until the front cover is
disengaged and the opening click is heard
(Fig 1)
2 Remove the printed circuit board by spread
out the two tabs, which are located on the
either side of the lower half of the board
3 Break out the desired holes for proper wiring
4 Insert the wire through the wire access hole,
and mount the detector base to the wall,
corner or ceiling with the necessary number of
screws and the suitable bracket
5 Reinstall the PC board by place it on the lower
stoppers and push the PCB toward the
bottom cover
6 Access for wiring connections is easy via the
terminal block located on the PCB (Fig 3)
7 Replace the cover by inserting it back in the
appropriate closing pin until the closing click is
heard

CONNECTIONS
Terminal 1 – Marked “ - ” ( GND )
Connect to ground of the control unit
Terminal 2 – Marked “ + ” ( +12V )
Connect to a positive Voltage output of 8 2 -16Vdc
source (usually from the alarm control unit)
Terminals 3 & 4 - Marked “ RELAY ”
These are the output relays contacts of the
detector Connect to a normally closed zone in the
control unit
Terminals 5 & 6 - Marked “ TAMPER ”
If a Tamper function is required connect these
Terminals to a 24-hour normally closed protective
zone in the control unit If the front cover of the
detector is opened, an immediate alarm signal will
be sent to the control unit

MW SENSITIVITY ADJUSTMENT
JUMPER “JP1” - provides sensitivity control of
MW (DOPPLER) according to the environment.
Position Up – “H” – High sensitivity
For normal operation – immediately detection
Position Down – “L” – Low sensitivity
For harsh environments
POTENTIOMETER “RV1” – adjustment
according to protected area range
The potentiometer at mid-scale is equivalent to a
distance of 15m, at min-scale – 7m and
max-scale - is used with LR lens only
Dimension change according to installation
location and room size
PIR SENSITIVITY ADJUSTMENT
JUMPER “JP4” - provides sensitivity control of
PIR according to the environment
Position Up – “H” – High sensitivity
For stable environments
Position Down – “L” – Low sensitivity
For harsh environments
POTENTIOMETER “RV2” – adjustment
according to protected area range
Use RV2 to adjust the detection range between
68% and 100% (factory set to 84%) Rotate the
potentiometer clockwise to increase range,
counter-clockwise to decrease range
ALARM MODE SETTING
JUMPER “JP2” OR - AND
Position Left “OR”
The alarm signal (relays activation) occurred when
one of the sensor’s signals - PIR OR MW - is
present
The effective detection range is the range of the
PIR pattern OR MW pattern correspondently
Position Right “AND” - The alarm signal
occurred only when both sensors (PIR AND MW)
are present at the same time
The effective detection range is the range of which
the PIR patterns AND MW lobe are intersected
You must reset the detector from
Control anel before the new
settings will take effect.

LED ENABLE/DISABLE SETTING -
JUMPER “JP3” (FIG.4)
Position On (right) - LED ENABLE
The RED LED will activate when the SRDT-15
Is in alarm condition
Position Off (left) - LED DISABLE
The LEDS are disabled
Note: the state of the Jumper “JP3” does not
affect the operation of the relay
When an intrusion is detected, the LED will
activate and the alarm relay will switch into alarm
condition for 1 6 sec
LED INDICATORS (Fig 4)
YELLOW LED - MW detection’s
GREEN LED - PIR detection’s
RED LED - Alarm
TEST PROCEDURES
Wait one-minute warm-up time after applying
12 Vdc power Conduct testing with the protected
area cleared of all people
Walk test
1 Remove front cover
Set LED to ON position
2 Reassemble the front cover
3 Start walking slowly across the detection zone
4 Observe that the red LED lights whenever
motion is detected
5 Allow 5 sec between each test for the detector
to stabilize
6 After the walk test is completed, you can set the
LED to OFF position
NOTE:
Walk tests should be conducted, at least once a
year, to confirm proper operation and coverage of
the detector

PATTERN SCALE CALIBRATION
To calibrate the MW pattern scale, You need the
size of the room (length and detection angle)
For Doppler pattern see fig 7 and table1 on
Page 18, where H – Doppler pattern max;
## - zone number;
a – angle;
X,Y – appropriate coordinates of
Doppler pattern
The potentiometer RV1(Fig 4) adjusts the
detection pattern scale between 30% and 100%
(factory set to 70%) Rotate the potentiometer
clockwise to increase pattern scale
Rotate the potentiometer counter-clockwise to
decrease pattern scale
The potentiometer at min “ – “ is equivalent to a
distance of 6m - 8m
