Visonic DUET-AM C/O Installer's Manual

DUET-AM C/O
Dual-Technology Microwave/PIR Intrusion Detector
1. FEATURES
 Combined Fresnel and cylindrical optics improves detection range
and false alarm immunity.
 Normally closed and normally open alarm outputs.
 Look-down "creep zone" lens.
 True Motion Recognition™ (TMR) algorithm (patented) for
recognition of true motion of a human body.
 DRO-stabilized MW microstrip technology.
 MW Motion Simulator simulates the effect of a human body moving
in the MW field (patent pending for MW self-test).
 Range control for adjusting the MW coverage.
 PIR self-test by applying a short heat pulse.
 Temperature compensation for the PIR section.
 Unique tamper protection mechanism.
2. SPECIFICATIONS
Input Voltage: 9 to 16 VDC
Note: For UL listed application, 4 hours of standby power must be
provided by the listed control unit or Listed burglar power supply. For
UL Listed application use only a Listed limited-power source.
Current Drain @ 12 VDC: 21 mA standby, 29 mA max.
PIR SECTION
Sensor: Low noise dual-element pyroelectric type
Tripping Indication: LED flashes green for up to 5 seconds
Motion Event Verification Counter: Selectable, 1 or 2 events
Front Lens Data (see Figure 2)
Beams: 32 in two layers (10 curtain beams in bottom layer)
Max. Coverage: 20 x 20 m (60 x 60 ft) / 90° field of view
Optional Long Range Lens 34D (see figure 2)
Beams: 16
Max. Coverage: 25x3m (82x10 ft.) / 6° field of view
Vertical Adjustment: FAR, MID and NEAR, by sliding the circuit
board along a 3-position scale.
MW SECTION
Oscillator: Microstrip DRO-stabilized Doppler sensor
Frequency: 10.687 GHz (in the UK only) or 10.525 GHz (10.525 GHz
for movement detector is prohibited or restricted from use in Austria,
Czech Republic, Estonia, Finland, French, Germany, Portugal, Slovak
Republic, Turkey, UK, Spain and Sweden).
Detection Range Control: Adjustable from 25% to 100%
Tripping Indication: LED lights green for up to 5 seconds
ALARM, TAMPER & TROUBLE DATA
Alarm Indication: LED lights red for 1.5 to 5 seconds if both sensors

internal resistance. If DIP switch 3 is in OFF position the contact is
normally open type. The contact closes in case of alarm (1.5 - 5
seconds). If DIP switch 3 is in ON position the contact is normally
closed type. The contact opens in case of mask detection or in case
of internal circuit failure. The contact closes constantly in case of
power failure regardless of DIP switch 3 position.
Alarm Duration: 1.5 to 5 seconds
Tamper Switch: N.C., rated at 50 mA resistive / 30 VDC
Masking Detection Delay: About 60 seconds
Trouble/ Masking Indication: LED alternately flashes green and red
and if DIP switch 3 is in ON position, NO/TRB relay opens until the
detector is reset.
