BASIC OPERATION
This unit is a combination passive-infrared (PIR) sensor and
microwave sensor, both contained in a single package. The
unit will go into alarm when both sensors detect intrusion at
the same time. 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 temperature changes (as from space heaters or air
conditioners, for example), but is sensitive to motion. Strong
vibrations can be troublesome. Microwave signals may
pass through non-metallic walls and windows. Infrared is
virtually unaffected by vibration, and will not penetrate walls
or windows.
Thus the two technologies complement each other, and it is
the combination of the two that provides an inherent immun-
ity to false alarms. Dual technology is ideal for use in hostile
environments. Since both must trip to cause an alarm, in-
stallation is easier and requires less discipline.

STANDARD LENS
The supplied lens will perform best in typical applications,
thus it is factory installed. Following are its specifications.
Number of Zones: 18 zones, 40 beams, plus "Look-
down".
Maximum Coverage: 50ft. long x 40ft. wide
Field of View: 80°
Note: (1) Should the lens become heavily soiled, it
may be cleaned using lukewarm water and a mild deter-
gent. To dry, use a soft lint-free cloth or allow to air dry.
(2) If the standard lens does not suit the application, select
another available lens. Note: Non-standard lenses have
not been evaluated by UL.
INSTALLATION
CHOOSING A SUITABLE LOCATION
The unit may be either wall mounted or corner mounted.
Corner mounting is generally recommended as greater
coverage may be obtained. Select a rigid surface that is
relatively free of vibration.
Position the sensor with respect to access doors or win-
dows 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 ren-
dering the unit free from false alarms, neither sensor
should detect intrusion under normal conditions. Note:
The unit is shipped from the factory with jumper 4(A)
ALARM installed in Jumper Block J1 to allow the LED
to indicate simultaneous PIR and Microwave trips.
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. A round push-thru
hole permits cable entry at the bottom. Cutaway notches
in the rear case will accommodate surface-mounted ca-
bles if the outer jacket is removed. After the proper knock-
outs have been removed, the rear case may be used as a
template to mark drill holes. Note: Any unused knockout
must be sealed with thecaulking material supplied to
eliminate drafts and prevent entry by insects. If mounting
higher than 3 meters, it may be necessary to tilt the unit
downward slightly for proper microwave coverage, and to
reset the Height Scale slightly for proper PIR coverage.
WIRING
Complete the terminal connections as follows:
Power (Terminals 1 [S] & 2 [S]): Connect to the [S] and
[S] terminals on the GEMC-BSLC.
SETTING THE HEIGHT SCALE
The Height Scale must be set to obtain the maximum rec-
ommended coverage. Remove the front cover. Note that
the Height Scale is printed along the edge of the circuit
board in the upper-left corner (see Fig. 3). The scale cali-
brations represent sensor mounting height (6 feet to 9.8
feet or 2-3 meters maximum) for the standard wide-angle
lens only. To set, loosen the Lock Screw shown in the
illustration to slide the board up or down, and align the
Pointer Mark groove in the rear case with the index Height
Scale on the PC board representing the mounting height
of the unit. Then tighten the Lock Screw (do not over-
tighten!).
LOOK DOWN ZONE
Coverage sensitivity is extended to the "Look-down" zone,
located directly below the unit. To remove the Look-down
zone, simply remove the lens from the Look-down holder.
You may wish to remove the Look-down lens if there are
large pets that may get below the unit.
JUMPER BLOCK
The Jumper Block "J1" (see Fig. 4) is used to select oper-
ating modes, numbered 1-5 from left to right, as follows:
Jumper 1(S) SENSITIVITY. Install this jumper for high
sensitivity or when using in narrow areas or corridors.
Jumper 2(D) LED DISABLE. Install this jumper if you
want to disable the LED.
After testing, be sure to either install jumper 4(A) ALARM
for normal LED operation where the LED lights upon an
alarm condition, or install jumper 2(D) LED DISABLE to
prevent the LED from lighting upon an alarm condition.
Note: Regardless of theposition of this 2(D) LED DIS-
ABLE jumper, troubles will always bedisplayed on the
keypad.

Jumper 3(P) PIR. Install this jumper for PIR Walk-Test
Mode; LED indicates PIR trips only. The PIR coverage is
adjusted by resetting the Height Scale (see SETTING THE
HEIGHT SCALE).
Jumper 4(A) ALARM. Install this jumper for LED to
indicate simultaneous PIR and Microwave trips (the LED
will indicate a condition that would cause an alarm if the
system were armed).
Jumper 5(M) MWAVE. Install this jumper to enable Mi-
crowave Walk-Test Mode; LED indicates microwave trips
only.
RANGE ADJUSTMENT
The Microwave Range Adjust control (see Fig. 3) should be
set at the minimum required to achieve the desired cover-
age. It is set so that the LED lights when motion is detect-
ed at the maximum desired range.
All tests MUST be made with the front cover in place.
1. Remove the front cover and install jumper 5(M)
MWAVE to enable Microwave Walk-Test Mode (LED
will indicate microwave trips only).
2. Set the Microwave Range Adjust control at mid-position.
Replace the front cover and walk test the unit (turn knob
clockwise to increase range).
3. If the desired range is insufficient, increase the Micro-
wave Range Adjust slightly and repeat the test as
necessary, increasing the control each time, until motion
is detected at the desired range. (If the desired range
was excessive, decrease the control slightly and repeat
this step). Turn knob counter-clockwise to decrease
range.
4. Re-install jumper 4(A) ALARM for the LED to indicate
simultaneous PIR and Microwave trips.
NOTE: The proper setting of the Microwave Range
Adjust control is when motion is detected at the
desired range. Because the range of the microwave
detector is not limited by the confines of walls, windows
or doors, further advancement of the control may result
in detection of motion beyond the desired coverage ar-
ea.
TESTING THE COVERAGE AREA
After the unit has been mounted and set up, its coverage
should be tested and, if necessary, altered to accommo-
date local environmental conditions (within the coverage
area). Satisfactory checks may be made using the 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 temperature. After sufficient time has
been allowed, proceed as follows.
Test the range of the coverage
Install jumper 3(P) PIR to enable PIR Walk-Test Mode.
Replace the front cover. Walk out to the maximum deter-
mined coverage distance, then walk across the field of cov-
erage. The LED will remain lit as long as motion is detect-
ed.
Remove jumper 3(P) PIR and install jumper 5(M) MWAVE.
Replace the cover and repeat test.
Remove jumper 5(M) MWAVE, and install jumper 4(A)
ALARM. Replace the cover and repeat test. Confirm
that the LED lights at the maximum desired range.
Zone Masking
A problem zone may be deactivated in order to preserve
reliable system operation by zone masking the lens. Care-
fully apply a piece of zone masking foil (supplied) to the
inside grooved surface of the lens segment representing
the problem zone to block signal from the offending device
(refer to Fig. 5).
Fig. 5. Zone masking foil
(shaded area) applied to a
lens segment to deacti-
vate a problem zone.
COMPLETING THE INSTALLATION
When testing is finished, for proper operation, no jumpers
should be installed at 5(M) Microwave or 3(P) PIR Walk
Test positions.
 When jumper 4(A) ALARM is installed,theLED indi-
cates simultaneous PIR and Microwave trips (a condi-
tion that would cause an alarm if the system were
armed).
 When jumper 2(D) LED DISABLE is installed, the
LED is prevented from lighting upon simultaneous PIR
and Microwave trips (a condition that would cause an
alarm if the system were armed).
