BASIC OPERATION
These units comprise a passive-infrared sensor and microwave sensor
housed in a single package. The unit will go into alarm when both PIR and
microwave sensors detect intrusion at the same time. The design is such that
small animals within the coverage area will not be detected.
The PIR section operates by detecting a rapid change in temperature when
an intruder crosses a protected area. When a beam experiences a change
in heat (projected back through the lens), a pulse is generated by the sensor
element. The microwave transmitter sends out short bursts of rf energy, and
the receiver detects changes in the returned signal caused by motion within
its coverage area.
The microwave section is unaffected by visible light, air drafts, or tempera-
ture changes (as from space heaters or air conditioners, for example), but is
sensitive to motion. Strong vibrationscan betroublesome. Microwave signals
may pass through non-metallic walls and windows. Infrared is virtually unaf-
fected by vibration, and will not penetrate walls or windows.
4

Thus the two complementary technologies provide an inherent immunity to
false alarms. Dual technology is ideal for use in hostile environments. Since
both must trip simultaneously to cause an alarm, installation is easier and
requires less discipline.
PIR ZONE DIMENSIONS
Regardless of the lens pattern selected, or the number of PIR beams
produced by the lens, the relative proportions of beam width, beam height,
beam separation, and zone width always remain the same and are illustrated
in Fig. 1. Note that beam and zone dimensions at any distance may be
calculated by the following formulas.
Beam Width “w” (in.) = Distance “d” (ft.) x 0.4
Beam Separation “s” (in.) = Distance “d” (ft.) x 0.4
Beam Height “h” = 2 x Beam Width “w”
Zone Width “z” = 3 x Beam Width “w”
Examples: At 10’, a zone is 8” high x 12” wide.; at 30’, it is 2’ high x 3’ wide.
DETECTION PATTERNS
Figure 2 illustrates maximum PIR and microwave detection patterns super-
imposed on each other. PIR detection patterns are adjustable, within limits,
both vertically and horizontally (see ADJUSTING THE COVERAGE AREA
for detailed adjustment procedures).
The microwave detection patterns shown are for free space. In practice,
when confined by walls and ceilings, reflected waves tend to flood the area,
providing volumetric coverage. Furthermore, when used in long, narrow
corridors, the effective range may be extended by as much as a factor of 2
due to the guiding effect that the corridor has on microwave energy. Micro-
wave detection range is adjustable. Reducing range, however, will reduce all
other dimensions proportionately.
Insensitive Areas
The insensitive area is that area directly beneath the unit within which an
intruder is undetectable. It is shown as a shaded area in the side-view
detection pattern that follows, and assumes that an intruder will be at least 5’
tall and that the protected area is not accessible by crawling or crouching.
Thesizeof theinsensitive areawill increase asthe mountingheight increases
(see Fig. 2b). Nevertheless, it may be necessary to increase the mounting
height in order to avoid an object that could obstruct the coverage pattern.

STANDARD LENS
This model uses a standard lens that yields the 18-zone, 40-beam pattern
illustrated in Fig. 2. The coverage pattern is adjustable, within limits, both
vertically and horizontally (see ADJUSTMENTS: Aiming the Beams for
detailed adjustment procedures). Stacked optical centers provide tall, dense
beam pairs, making beam aiming easier and less critical. Examples shown
herein are typical and will not apply to all cases. Always test the coverage
pattern after the unit is installed (see TESTING THE COVERAGE AREA).
The supplied lens will perform best in typical applications, thus it is factory
installed. Following are its specifications.
Number of Zones: 18 (3 layers: 9/5/4 zones)
Number of Beams: 40 (3 layers: 18/10/12)
Maximum Coverage: 30’ long x 35’ wide
Field of View: 85°
Mounting Height: 7 to 8’
Note: (1) If heavily soiled, clean lens using lukewarm water and a mild
detergent. Dry with soft lint-free cloth or allow to air dry. (2) If lens is not
suitable, select another (see ORDERING INFORMATION).

INSTALLATION
CHOOSING A SUITABLE LOCATION
The unit may be either wall mounted or corner mounted. Select a rigid
surface that is relatively free of vibration.
Positioned the sensor with respect to access doors or windows so that an
intruder will pass across its field of view, not directly toward or away from it.
Avoid areas containing devices that may pose a chronic problem to either
sensor. For the dual-technology feature to be truly effective in rendering the
unit free from false alarms, neither sensor should detect intrusion under
normal conditions. Note: The unit is shipped from the factory with Jumper J1
in the Alarm position.
Inselectingmounting height, aiming,and range,also considerthe following:
•(1) the size and shape of the area to be protected. In a large or irregularly-
shaped area, the use of two or more units may be advisable for volumetric
coverage;
•(2) the PIR lens installed (see ORDERING INFORMATION for available
optional lenses);
•(3) objects that may block detection;
•(4) animals in the protected area; and
•(5) an intruder’s likely path, usually determined by the location of a door
or window.
MOUNTING THE SENSOR
Open the case by inserting a small screwdriver in the slot at the bottom and
pushing up slightly. Remove the front cover.
An array of “push-thru” holes is provided in the rear case to simplify wall or
corner mounting. (If corner mounting, do not use the hole at the lower-left
corner, near the terminal strip.) A round push-thru hole permits cable entry at
the bottom (see Fig. 4). Cutaway notches in the rear case will accommodate
surface-mounted cables if the outer jacket is removed. Note: Any knockout
that has been removed but not used should be sealed with the caulking
material supplied to eliminate drafts and prevent entry by insects.
WARNING: This unit will not detect pets under 2’6" in height or under 40 lbs. in weight.
IMPORTANT! For optimum results in pet applications,
•Mount the unit at 7–8’, adjust the microwave gain control to the
minimum setting required to detect a intruder.
•Choose a location where the pet cannot get close to the unit.
•Adjust microwave for minimum range that gives desired detection.
•If protecting an area with a pet over 2’6" or 50 lbs., mount unit at a
height of approx. 5 to 6 feet and install lens (P/N: LENS817).

CHANGING THE LENS
The lens is “sandwiched” between the front
case and a Lens Support Insert, which also
servesto hold the LED jewelinplace. Toinstall
one of the accessory lenses, proceed as fol-
lows.
1. Push up on the lower edge of the Lens
Support (see Fig. 3) until it is clear of its retain-
ers, then pull out the Lens Support from the
bottom. Be careful not to dislodge the LED
jewel. Note: If the jewel pops out, re-insert it
with the small index key positioned at the top.
2. Slide out the lens and install the replace-
ment correctly oriented.
3. Replace the Lens Support: Slip the Lens Support under the top lens
guides with its two tabs straddling the LED jewel, then push in at the bottom
until the Lens Support snaps into place.
WIRING
Removethewireentryhole(seeMOUNTINGTHE SENSOR)to gainaccess
to the terminal strip. (Be sure to caulk around the wires where they exit the
case; see previous Note.) Route wires to the terminal strip as shown in Fig.
4 and connect as follows:
Power (Terminals 1 [+] & 2 [–]). Apply 12Vdc to Terminals 1 [+] and 2 [–].
The power source may be regulated or unregulated. Power should be
suppliedfromacontrolpanelorotherpowersourceequippedwitharecharge-
ablebatterybackuptomaintainoperationintheeventofapowerfailure.Refer
to SPECIFICATIONS for power-supply requirements.
Alarm Relay (Form A) Contacts (Terminals 3 & 4). These contacts are
rated at 100mA, 24Vdc and are normally closed. When the sensor is operat-
ing,eitherdetectionofan intruderorlossofpowerwillcausetherelaycontacts
to open. (This mode of operation is required in UL installations.)
Alarm Relay (Form C) Contacts (Terminals 3, 4 &5). These contacts are
ratedat 100mA, 24Vdc.Terminal 4is common. Terminal3 isnormallyclosed;
Terminal 5 is normally open. When the sensor is operating, either detection
of an intruder or loss of power will cause the relay to trip. (In UL installations,
normally-closed terminals (3 and 4) must be used.)
Status (Form-A Version only) and Trouble (Where equipped)
Wiring to Terminals 5 (Status) and 6 (Trouble) are only required if using the
specialfeaturesof thisunit. Refer toADVANCED FEATURES andthe Wiring
Diagrams at the back.
Status Input (Form-A Version only, Terminal 5). Connect to the Status
terminal (Arm Lug) of the control panel. A low at Terminal 5 tells the sensor
Fig. 3. Removing the

that the panel is armed.
Trouble (Terminal 6). This is an open-collector output that produces an
active low to signal a trouble condition.
ADJUSTING THE COVERAGE AREA
Self Test
Theself-test diagnostic simulatesmotion and tests thePIR sensor, amplifier
and related PIR circuitry, the microwave transmitter, receiver, andassociated
microwave circuitry. This test is initiated each time the unit is powered up and
randomly at 11- to 16-hour intervals after the last alarm to assure that the unit
is always in operating order. At power-up, the LED will come on and both the
alarm and trouble outputs will be held “safe”. If the unit is operating properly,
the LED will extinguish after about 1 minute. However, if it fails the self test,
the LED will flash rapidly, indicating a need for service. After the LED goes
out, indicating a successful self-test, proceed as follows.
Lateral Beam Adjustment
PIR beams may be shifted up to 6° in either direction (±1⁄2zone for the
Standard Wide-Angle lens). The left edge of the top lens guide acts as the
index for lens alignment. Figure 5 illustrates the relative positions of the index
and lens alignment notches. To align a lens, proceed as follows. (Caution:
To prevent soiling, handle the lens only with clean fingers.)
Fig. 4. Circuit board layout. 9

1. Check that lens is installed smooth side out, grooved side in.
2. To aim beams straight out, set Notch “B” to left edge of top lens guide.
3. To aim beams 6° to the right, set Notch “A” to left edge of top lens guide.
4. To aim beams 6° to the left, set Notch “C” left edge of top lens guide.
Jumper Block
TheJumper Block(see Fig.6) is used to select operatingmodes, asfollows:
LED. LED Disable. Install to disable LED Alarm
indication only.
PIR. PIR Walk-Test Mode. LED indicates PIR
trips only.
ALARM. Alarm. LED indicates simultaneous
PIR and Microwave trips.
MW. Microwave Walk-Test Mode. LED indicates
microwave trips only.
Important!Thealarmrelaywill operateonlywith
the LED jumper installed or the ALARM jumper
installed. Therefore, after testing, be sureto replacethe jumper inthe ALARM
position for normal LED operation, or in the LED position, which prevents the
LED from lighting on an alarm condition.
Four-Pulse Mode. This is the least-sensitive mode, recommended for
hostile environments or areas with pets larger than about 40 pounds, where

an intruder must cross several beam pairs to trip an alarm. To lock the unit
intothe4-PulseModewhilemaintainingadaptivemicrowaveoperation,install
both the PIR jumper and the MW jumper.
Microwave Range Adjustment
Important! The microwave RANGE ADJUST control should be set at the
minimum required to achieve the desired coverage. It is set so that the
Walk-TestLEDlightswhenmotion isdetectedatthe maximumdesiredrange,
but does not light (motion is not detected) beyond the maximum desired
range. All tests must be made with the front cover in place.
1. Remove the front cover and install the MW jumper.
2. Set the RANGE ADJUST control at mid position. Replace the cover and
walk-test the unit. (Note: Allow at least 5 seconds after trip for microwave to
reset.)
3. If the desired range was insufficient, advance the RANGE ADJUST
control slightly clockwise. Repeat the test as necessary, increasing the
RANGE ADJUST control each time until motion is detected at the desired
range, but not beyond. (If the desired range was excessive, reduce the
RANGE ADJUST control slightly (counterclockwise) and repeat this step.)
Note: Return the jumper to the ALARM or LED position after adjustment.
TESTING THE COVERAGE AREA
After the unit has been mounted and set up, its coverage should be tested
and, if necessary, altered to accommodate local environmental conditions
(within the coverage area). Satisfactory checks may be made using the
Walk-Test LED on the front of the unit. It is recommended that the coverage
area be tested at least once a year.
Testing the Unit
Complete connections to the terminal strip (see WIRING). The unit will
require a 1-minute “settling” time to adjust itself to the surrounding tempera-
ture. After sufficient time has been allowed, proceed as follows.
Move your hand slowly across the lens to verify sensor operation. With the
PIR jumper installed, the LED will light whenever a beam is disturbed. With
the MW jumper installed, the LED will light as long as motion is detected.
When the LED goes out, no motion is detected.
Test the range of the coverage. Install the PIR Walk-Test jumper and
replace the front cover. Walk out to the maximum determined coverage
distance, then walk across the field of coverage. The LED will remain lit as
longas motionisdetected. Repeat thistest withthemicrowaveMWWalk-Test
jumper installed. Repeat once again with the ALARM. jumper installed.
Confirm that the LED lights at the maximum desired range, but not beyond.
Test the width of the coverage. Install the PIR Walk-Test jumper (Fig. 6)
and replace the front cover. Walk across the coverage area and confirm LED
response. Repeat with the MW Walk-Test jumper installed, and once again
11

with the ALARM jumper installed.
Test for environmental disturbances.
Note: The following test is applicable to the PIR section only. There are no
provisions for testing the microwave section for environmental disturbances.
This test will determine if detection occurs with no human activity in the
protection area. Be sure to make this test with all potential disruptive devices
(heaters, air conditioners, etc.) in full operation. Note that blowing curtains
may be troublesome.
Install the PIR Walk-Test jumper. Leave the protection area. If an alarm
conditionoccurswith no oneinthecoverage area, temporarilyblocktheentire
lens with a sheet of cardboardor other opaque material. If thealarm condition
persists with the lens covered, it is not caused by an environmental distur-
bance, and the system requires attention. (Check for low supply voltage from
the control center, or for an intermittent connection.)
Remove the cardboard (or other material) from the front of the lens. If the
alarm condition reoccurs, turn off heaters, air conditioners, etc. one by one
and note the effects. If the offending device must remain in operation within
the coverage area, try to reposition the device and/or alter the aim of the
sensor slightly to effect a suitable compromise. Bear in mind, however, that
each time the coverage pattern is altered, the foregoing environmental test
must be repeated.
Zone Masking
If a workable solution cannot be achieved using the above technique,
selective zone masking will be required. This will deactivate a problem zone
in order to preserve reliable
system operation. Carefully
apply a piece of zone-mask-
ing foil (supplied) to the
grooved inside surface of the
lens segment representing
the problem zone to block
signal from the offending de-
vice (refer to Figs. 7 and 8).
Figure 8 illustrates the zone-masking foil supplied. Remove one or more
segments that most closely match the lens segment of the offending zone
and affix to the inside surface of the lens. Note that the foil must beaccurately
positionedsoasnot to affectadjacentzones.(Zonesegments maybelocated
by holding the lens up to the light.) Any oil or grease on the surface of the
lens(or onyour fingers) willreducethe adhesivequality ofthe foil. Important:
After the foil is properly applied, rub it down against the lens (using the tip of
a ball-point pen, for example) to improve surface contact.
If necessary, re-aim and retest the sensorafter masking one ormore zones.

COMPLETING THE INSTALLATION
The jumper must be in either the
ALARM position or the LED position for
the alarm relay to operate. (If the 4-pulse
mode is selected, both the PIR and MW
jumpers must be installed.) With the ALARM jumper (or PIR & MW numpers)
installed, the LED will indicate a condition that would cause an alarm if the
system were armed. To extinguish the Walk-Test LED after testing, place the
jumper across the LED terminals. In this position, the LED is disabled during
normal operation, but is enabled for diagnostic indications.

OPTIONAL LENSES
Pet Alley Lens (LENS817)
A pet alley is an insensitive area above floor level that will reduce the
possibility of pets (dogs, cats, etc.) or pests (mice, rats, etc.) from causing an
alarm. Note: Mount the unit at a height of 6’ for this application.

ADVANCED FEATURES (Where available)
Trouble Output
Terminal 6 is an open collector Trouble output; a trouble condition is
indicatedby anactivelow andis maintained.The trouble outputmay be wired
to an unused zone at the panel for local display at the keypad. (In UL
installations, connect only to a UL-listed Control Unit Accessory having LED
indication.) While troubles can report to a central station, local annunciation
may be preferable in order to reduce telephone congestion and operating
costs.
Quick Response Mode
If Terminal 5 is connected to the Status Terminal (Arm Lug) of the control
panel, the sensor will provide a quicker response time while the panel is
disarmed. Note: The control panel’s Status Terminal must provide a low
output when armed.
