Visonic DUET-AM Installation Instructions

DUET-AM, DUET-AM G3
Dual-Technology Microwave/PIR Intrusion Detector
1. FEATURES
• Combined Fresnel and cylindrical optics improves detection
range and false alarm immunity.
• 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.
• Programmable motion event counter (1 or 2 events).

:
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: Adjustable from 25% to 100% (5 m to 20 m)
Tripping Indication: LED lights green for up to 5 seconds
ALARM, TAMPER & TROUBLE DATA
Alarm Indication: LED lights red for 1.3 to 5 seconds if both
sensors trip
Alarm output: Solid State Relay. NC, 100 mA / 30 VDC, 35 ohm
maximum internal resistance. "Open" for 2 – 3 sec. in case of
alarm, masking event (applicable for DUET-AM G3 only) or
complete power failure.
Alarm Duration: 1.3 to 5 seconds
Tamper Switch: N.C., rated at 50 mA resistive / 30 VDC
Trouble output: Solid State Relay. NC, 100 mA / 30 VDC, 35
ohm maximum internal resistance. "Open" in case of auto-
diagnostic failure, Anti-Mask event, low voltage (applicable for
DUET-AM G3 only) or complete power failure.
Masking Detection Delay: About 60 seconds
Trouble/ Masking Indication: LED alternately flashes green and
red and TRB relay opens until the detector is reset.
3. INSTALLATION

3.1 Installation Tips

To minimize false alarms:
Do not aim at heat sources
DE1812
Mount on solid, stable surfaces

Installation Instructions

• Simple-to-use, three-position
vertical adjustment.
• TEST input to enable/disable
the walk test LED remotely
(per new European standard).
• Relay output for trouble.
• Anti-masking protection.
• White light protection.
• Optional swivel brackets for
wall or ceiling installation.
• DUET-AM
G3 has back
tamper switch and low-
voltage detection.
MOUNTING
Form: Surface or corner (no
brackets); surface, corner and
ceiling with brackets
Height: 2 - 2.6 m (6.5 - 8.5 ft)
without bracket, 2 - 3.6 m (6.5 -
12 ft) with bracket.
Note: Mounting heights
greater than 2.6m (8.5 ft) may
reduce the detector's coverage
range.
Caution: with brackets in use,
effective detection ranges may
differ from those indicated in
Figures 2 and 8.
Optional Brackets: BR-1
(surface), BR-2 (corner) and
BR-3 (ceiling).
