SENSORS | DUAL TEC
DUAL TEC Family Features
Animal Immune to 100 lbs.: Sensor is immune to pets and other animals with combined weight of 100 lbs. when installation guidelines for animal immunity are followed
Coverage Pattern: Length by width of area protected
Signal Processing:
Analysis performed on PIR and microwave signals to determine alarm
conditions ■
DualCore – Signals are analyzed in multiple domains, including amplitude, time, frequency and duration. Supports functions including diagnostics and other advanced false alarm features.
■
C3 – Correlates data from both channels simultaneously, instead of independently processing each
■
MAP – Timing and sequence of signals are compared to settings for specific environments to qualify each channel individually
■
Queue Event Logic – Pulse counting while looking for specific sequences of events
■
Advanced – Pulse counting with timing relationships
■ Standard – Basic pulse counting
Optical Technology: Technology used to collect infrared
radiation for PIR processing ■
Uniform Sensitivity – Fresnel lens that provides the same sensitivity at the edge of the pattern as exists directly in front of the sensor
■
Split-Zone – Zones are split into two sub-zones where each sub-zone has half the sensitivity of a regular zone, requiring targets to be in both zones for an alarm
■ Standard – Basic Fresnel lens ■ Mirror – Basic mirror optics
Microwave Frequency Band: Frequency at which the microwave signal is radiated and received. Higher frequencies generally penetrate non-metallic objects
less than lower frequencies. ■
S-Band – 2.54 GHz
■ X-Band – 10.525 GHz ■ K-Band – 24.125 GHz
Call 1-800-467-5875 for more information.
Environmental Adaption: Microwave thresholds are adapted either in hardware or digitally to remove the effect of low level interference such as ceiling fans
Temperature Compensation: Sensor automatically adjusts PIR thresholds and/or other parameters to adapt to change in ambient temperature
relative to human body temperature ■
■
Standard – Compensates at ambient temperatures below body temperature
Advanced – Compensates at ambient temperatures both below and above body temperature
Digital Fluorescent Light Filter: Software algorithms provide infinite rejection of microwave interference due to fluorescent lights
Analog Fluorescent Light Filter: Hardware circuitry provides rejection of microwave interferences due to fluorescent lights.
Anti-Masking:
Detects intentional and accidental blocking of the PIR optics
Walk Test Mode:
Determines the coverage pattern and functionality for both the PIR and microwave channels, usually through LED indicators
PIR Sensitivity Adjustment: Selectable option to change the PIR process sensitivity, usually through a DIP switch or jumper link
Microwave Sensitivity Adjustment: Selectable option to change the microwave sensitivity and/or range, usually through a potentiometer
Vertical Adjustment: Capability to adjust the vertical PIR detector position relative to the optics, usually through a vertical shift in the PCB. Usually used to adjust range at different mounting heights, or accurately set the coverage pattern for different lenses or mirrors.
Horizontal Adjustment:
Capability to shift the PIR zones left or right by a few degrees. Usually used to locate potential false alarm sources, such as a heating vent between zones, or to aim the optics in a particular direction, such as a hallway.
Trouble Output:
Separate output used to indicate supervision failures and/or anti-mask detection to the control panel
Alarm Relay Forms: Type of output relay used to signal
panel when an intrusion is detected. ■
■
Form A – Two-terminal relay with Normally Closed output when energized
Form C – Three-terminal relay with both Normally Closed and Normally Open outputs when energized
LED Indicators:
Light Emitting Diodes used to provide visual feedback about alarm state, supervision, walk test and other modes
of operation ■
■ 1 LED – Single red LED
3 LEDs – Red, green, yellow LEDs, usually with PIR and microwave channels associated with a specific color
Microwave Supervision: Automatic self-test of microwave channel for proper operation
PIR Supervision:
Automatic self-test of microwave channel for proper operation
Recommended Mounting Height: Suggested height to mount processor for optimal performance. Usually important for animal immune applications.
Operating Temperature: Temperature range at which the sensor can be expected to provide adequate protection. UL certification may have a narrower range.
Input Voltage: Voltage range at the terminal strip at which the sensor will operate. UL may have certified for a slightly narrower range.
Swivel Bracket Options: Brackets used to mount sensors in installations that have special aiming or mounting heights
