DUET-AM C/O 

Dual-Technology Microwave/PIR Intrusion Detector 

 

Installation Instructions

 

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. 

 Programmable motion event 

counter (1 or 2 events). 

 Simple-to-use,  three-position 

vertical adjustment. 

 TEST input to enable/disable 

the walk test LED remotely. 

  Relay output for trouble. 

  Anti-masking protection.  

 White light protection (not 

investigated by UL). 

 

Optional swivel brackets for wall 
or ceiling installation.

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 

trip 

Alarm Output (NC):

 Solid state,

 

N.C., 0.1 A resistive / 30 VDC; 35 

 

max. internal resistance. Contact opens (1.5 - 5 seconds) in case of 
alarm event or opens constantly in case of power failure. 

NO/TRB Output:

 Solid state,

 

0.1 A resistive / 30 VDC; 35 

 max. 

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.
