DESCRIPTION
The F2-220 is a dual detector employing both microwave (MW)
and passive infrared (PIR) motion sensors. The sensors are
combined through a microprocessor to provide intelligent motion
detection designed to eliminate single detector false alarms.
Significant technical features such as the PIR's Multi-Level Signal
Processing (MLSP), digital temperature compensation, a highly
reliable DRO microwave sensor and digital MW signal analysis
combine for a new level of detection sensitivity, stability and false
alarm immunity.
The PIR and MW systems are each designed as independent, high
quality motion detectors. When combined, the result is a detector
with unmatched performance.
The detector indicates an alarm when both sensors detect motion
within 10 seconds of each other. The first sensor, either the PIR or
MW, which detects motion will start the 10 second confirmation
period during which the other sensor must also detect motion. If
the first sensor’s detection is not confirmed within 10 seconds, the
unit disregards the alarm.

INSTALLATION
INSTRUCTIONS
LOCATING THE DETECTOR
Mount the detector in a dry indoor location which will force the
intruder to walk perpendicular to the beam, and allow the beam
pattern to adequately cover the area being protected. Survey the
mounting location and the area being protected for the following
potential problems.
MOUNTING HEIGHT
The Force2 is designed to provide optimum coverage when
mounted between 2.1m (7') to 2.4m (8’) from the floor. If the unit is
mounted above 2.4m (8’), the PIR will have a slightly longer range,
but the “dead” zone directly below the unit will be increased. If the
unit is mounted below 2.1m (7’) the PIR section will have a shorter
range and the “dead” zone directly below the detector will be
decreased.
NOTE: Optimum dual detector detection occurs when the
coverage patterns of the PIR and MW section are matched.
Differences between PIR and MW coverage patterns could
reduce its effectiveness.
REFLECTIVE / METALLIC SURFACES
Do not aim the detector at reflective surfaces or metallic surfaces
that could vibrate. Reflective surfaces could distort the PIR coverage
pattern; vibrating metallic surfaces or rotating fans could be seen
as motion by the MW sensor. Metallic surfaces close to the unit may
reduce MW sensitivity.
AIR FLOW
The Force2 is protected against air flow and airborne
contamination. However, do not locate the detector where it will
be subject to direct high air flow such as fans, hot air vents or open
windows.
CONTAMINATION
Do not locate the detector near a source of oil or water vapour,
such as a steaming kettle or cooking area in a kitchen.
SUNSHINE
The Force2 is resistant to white light but direct sunlight is a high
energy source. Do not locate the detector where it will receive
direct sunlight, particularly in the morning or evening when the sun
is low and may shine in through a window.
TEMPERATURE CHANGES
Do not aim the detector at objects that change temperature rapidly,
such as heaters or ovens.
OBSTRUCTIONS
Do not limit the desired area of protection by placing large objects
such as plants or filing cabinets, so as to obstruct the detector's
coverage pattern.
PETS
Do not aim the detector where pets may trigger either the microwave
or PIR motion sensors. If both sensors are tripped, an alarm will
result.
DISASSEMBLING THE DETECTOR
To open the detector, pull on the front of the detector while pressing
on the release at the bottom of the detector with a small screwdriver.
To remove the circuit board and sensor assembly from the detector
case, press gently on the top of the MW detector until the circuit
board unlocks and slides towards the bottom of the detector.
To replace the circuit board and sensor assembly, place the
circuit board assembly into the detector’s back so that the white
plastic frame fits into the two slots in the detector’s back. Press
gently on the bottom of the MW detector assembly to slide the
circuit board towards the top of the detector. The circuit board
assembly will snap firmly into place.
NOTE: To avoid damage to the detector, do not press against
any of the components on the circuit board when removing and
replacing the board.
