A BASIC DESCRIPTION
GENERAL
The PIRAMID XL2 (Passive Infrared And
Microwave Intrusion Detector) is an outdoor dual
technology sensor designed to provide volumetric
protection in a wide variety of outdoor applications.
The sensor uses the unique combination of
“Stereo Doppler” Microwave and Passive Infrared
technologies.
PIRAMID XL2 is configured for “And Gate”
operation; i.e. both technology portions must activate
simultaneously for the sensor to alarm. e microwave
portion detects the motion of the intruder, whereas the
passive infrared portion detects a change in infrared
radiation. When both technologies activate at the
same time, the sensor initiates an alarm condition.
For optimum performance it is best to use the
PIRAMID XL2 as a motion sensor to protect specific
assets and strategic areas. Generally the sensor is not
used along a perimeter fence area like an outdoor P.E.
Beam unless in a proprietary system with “on-site”
response or with video verification.

“cable holders”. (pg. 4)
8. Slide electronic assembly into housing.
Tighten the four faceplate screws. (pg. 5)
9. Loosen swivel slightly so sensor is held in place,
but can be aimed upward, downward and side-to-side
without using the Allen Wrench each time. (pg. 5)
10. Install XL-Sounder audible tester accessory. (pg. 8)
11. Locate protection pattern by walk testing. (pg. 5)
Careful aiming of the sensor can optimize pattern
coverage. (pg. 5-6)
12. Once the desired protection pattern coverage is
obtained, tighten the swivel locking screw to
lock the sensor in place.
13. For best false-alarm-free performance, it is
critical that you reduce the Sensitivity Control
to the lowest possible setting while maintaining
acceptable walk-test performance. (pg. 6-8)
14. If possible, reduce the Range Control.
Note: the “Rule of umb” is to adjust the sensor’s
sensitivity and range to the lowest possible settings
to attain the desired coverage.

INSTALLATION
MOUNTING PIRAMID XL2
1. e PIRAMID XL2 comes equipped with a wall
mount bracket. Install the wall mount bracket
where the sensor will be located. Ensure that it is
firmly mounted and free from extreme vibration.
Avoid visual obstructions that may block the
sensor’s field of view.
UNIVERSAL POLE MOUNT
2. For a pole mount installation, PROTECH
offers two universal pole mounts as accessory
items. Model PH-4 is suitable for poles with a
diameter of 11/2” to 41/2”
(3.8cm to 11.4cm)
. Model
PH-4A is suitable for poles with a diameter of
41/2” to 81/2”
(11.4cm to 21.6cm
). e wall mount
bracket mounts to the PH-4/PH-4A Universal Pole
Mount.
BEST MOUNTING LOCATION
3. e sensor should be mounted so that the most likely
direction of travel by the intruder is toward or away
from the sensor.
4. PIRAMID XL2 provides good transverse detection
capability only when adjusted in the higher sensitivity
settings (10, 9 and 8). Operating the sensor in these
higher settings may increase nuisance alarms. erefore,
to enable effective detection in the lower sensitivity
settings (1, 2, 3, etc.), it is best to locate the sensor to
detect approaching and receding movement.
5. Remove the Microwave Electronic Assembly from
the Housing/Shroud Assembly by loosening the four
screws on the sensor’s faceplate. Attach the housing/
shroud assembly to the mounting bracket using the
hex head bolt provided.
MOUNTING HEIGHT
6. e optimum mounting height of the sensor can vary
considerably depending on the model’s lens module,
security requirement and environmental conditions.
Refer to the table below for recommended
mounting heights.

WIRING AND PRELIMINARY
SET-UP
MINIMUM WIRE SIZE:
1. With the housing/shroud assembly attached to the
mounting bracket, feed the wire through the conduit
connector into the sensor housing. For power
connections, PROTECH recommends a minimum 18
AWG wire for wire runs greater than 50 ft (15.5m).
2. Remove terminal strip from the microwave electronic
assembly and wire according to the diagram below.
REMOVABLE TERMINAL STRIP
3. Observe the correct polarity at the power terminals.
SHIELDED CABLE RECOMMENDED
4. For best shielding from Radio Frequency Interference
(RFI) and transients due to lightning or electrostatic
discharge, PROTECH highly recommends the use of
shielded cable. When shielded cable is used, the cable
shield (and/or drain wire) should be connected to
Terminal 1 (HOUS’G GND) at each sensor. Terminal
1 is connected by a spring contact to the housing, but
is not otherwise connected to the electronic circuitry.
e other end of the shield should be connected to
a common ground (generally the same ground used
for the power supply or control unit). Regardless of
the type of cable used, Terminal 1 (HOUS’G GND)
should always be connected to a good earth ground.
CABLE HOLDERS
5. After wiring the removable terminal strip, plug it
back into the Microwave Electronic Assembly. Route
cable under “cable holders” which are provided on
the circuit board.

6. Slide the Microwave Electronic Assembly back into
the housing, pulling the excess wire out of the rear
of the housing. Tighten the four-faceplate screws
uniformly to obtain a weather seal between the front
bezel and the housing gasket.
7. Make sure the
tamper switch actuator arm is fully
depressed when it contacts the rear of the housing
for a NORMALLY CLOSED contact on terminals
8 and 9.
8.
In most installations, it is best to aim the sensor at
a slightly downward angle as this minimizes the
small “dead zone” directly beneath the sensor. is
also helps to terminate the sensor’s protection
pattern within the protected area.
9. Apply power (8.5 to 20 VDC) to terminals 2(-)
and 3 (+) and allow at least 1 minute of
stabilization time before walk testing.
10. Check the LED On/Off Switch to verify that it is
in the “ON” position. e LED On/Off Switch
controls the “Walk Test” LED’s and the Voltage
OK LED.
11. Observe the Green Voltage OK LED on the
printed circuit board to verify that it is “ON”. e
Voltage OK LED will TURN ON continuously
when the input voltage reaches 10.5 VDC and will
TURN OFF when the input voltage drops below
9.5 VDC.

SENSOR ADJUSTMENTS
e key to success in many applications is the
proper adjustment of the sensor’s Range Control
Switch, Sensitivity Control Switch and Bird/Animal
Control Switch. Note: Refer to diagram on Pages
13 and 14 for detail.
RANGE CONTROL SWITCH
e Range Control Switch adjusts the overall
size of the sensor’s detection area. It may be necessary
to set the sensor at the higher settings (70, 80, 90
and 100 percent of maximum) to attain the desired
protection pattern coverage.
Note: Although the sensor can be set at
maximum range and operate properly, the “rule of
thumb” is to set at the lowest setting to attain the
desired range.
SENSITIVITY CONTROL SWITCH
The Sensitivity Control Switch adjusts the
amount of movement required for an alarm condition.
e Sensitivity Control Switch is very precise as the
PIRAMID XL2 can determine the exact “distance
in inches (cm.)” that an object must move to initiate
an alarm. e following table shows the amount of
movement required based on the switch setting.
WALK-TESTING
1. e Analytic Walk Test LED’s are very difficult
to see in bright sunlight. erefore, PROTECH
highly recommends that the XL-SOUNDER
Audible Tester be utilized for sensor walk-test.
e XL-SOUNDER will enable a single installer
to walk-test the sensor and will greatly reduce
installation time!
HELPFUL HINTS FOR WALK TESTING
2. It is best to start with range and sensitivity settings
at maximum. Loosen swivel locking screw just
enough so that the sensor will be held in place but
can be aimed slightly upward and downward in
approximately 1 degree increments. It is best to locate
the IR protection pattern first. e IR sensor portion
is most sensitive to movement across the pattern and
therefore walk testing should entail taking a few
steps across (transverse) the area at the maximum
desired range. Once the desired IR protection
pattern is located, tighten the swivel-locking
screw to lock the sensor in place. e microwave
protection pattern overlaps the passive infrared
pattern and should be present.
Now that the proper sensor alignment is locked
in place, try to reduce the sensitivity first. e lower
the setting, the better the false alarm rejection.
Next, try to reduce range. e “Rule of thumb” is to
adjust the sensor’s range and sensitivity to the lowest
possible settings to attain the desired coverage.
IMPORTANT: e most critical adjustment
for false alarm rejection is the SENSITIVITY
CONTROL. Settings of 1, 2, 3, and 4 are best
for false-alarm-free performance.

IN INCHES / CM
e PIRAMID XL2 provides good detection in
all ten sensitivity settings with respect to movement
toward or away from the sensor. Keep in mind that
in the lower sensitivity settings (1, 2, 3, 4, and 5)
transverse detection (“crosscatch”) is very sluggish.
erefore, it is important for the sensor to be located
so that the most likely point of travel is slightly
toward or slightly away from the sensor.
Proper mounting location of the PIRAMID
XL2 will enable lower sensitivity settings. Lower
sensitivity settings will enhance false-alarm-free
performance.
Note: Each sensor should be periodically
walk-tested to ensure that the required detection
is attained.

WALK-TEST PROCEDURE
FOR ANALYTIC WALK TEST LED’s
1. Remain motionless outside the protection area
until both Green LED’s are on steadily.
2. Walk into the surveillance area while observing
all LED’s.
3. Both Green LED’s turn off (responding to
motion and changes in infrared radiation)
followed by the Microwave Yellow LED and the
Passive Infrared Red LED turning on.
4. Master Alarm Red LED in the center of
the sensor faceplate turns on when both the
Microwave Yellow LED and Passive Infrared Red
LED are on simultaneously.

alarm rejection as well as good detection sensitivity
in the Standard Immunity Setting.
Enhanced Immunity Setting - Often used as
a last resort to eliminate nuisance alarms caused by
an abundance of birds and animals in the protected
area. e use of a Pet Alley Lens Module (Lens
A-Pet, Lens B-Pet and Lens C-Pet) in conjunction
with the Enhanced Immunity Setting would also be
highly recommended in animal prone applications.
In the Enhanced Immunity Setting, overall detection
sensitivity of the PIRAMID XL2 sensor will be
reduced approximately 20%.
Caution: In the Enhanced Immunity Setting the
speed of detection is significantly reduced. erefore,
the PIRAMID XL2 may not detect an intruder or a
vehicle traveling at a rate of speed above 3
