The NEXT MCW is a microprocessor-controlled wireless digital 
PIR detector, designed for easy installation, free of vertical 
adjustment. It features a cylindrical lens with uniform detection 
sensitivity throughout its operating range, up to 12 meters (40 ft), 
with wall creep zone protection.  
The advanced 

algorithm 

(patented)

 

allows the NEXT MCW to distinguish between the true 

motion of an intruder and any other disturbances which may 
cause false alarms. 
An on-board motion event jumper determines whether 1 or 2 
consecutive motion events triggers an alarm. 
The NEXT MCW includes the following features: 

• 

Incorporates a fully supervised PowerCode transmitter 

• 

Patented sophisticated motion analysis algorithm - True Motion 
Recognition (TMR™) 

• 

Sophisticated frequency domain digital signal processing 

• 

No vertical adjustment is needed 

• 

Programmable motion event counter 

• 

After detection, the detector disarms itself to save battery 
power. It rearms (reverts to the ready state) if there is no 
subsequent detection throughout the following 2-minute period 

• 

Very low current consumption 

• 

Microprocessor-controlled temperature compensation 

• 

Sealed chamber protects the optical system 

• 

Front cover tamper switch. 

• 

Back tamper switch (option) 

• 

White light protection 

• 

Elegantly styled, sturdy case
