Installation Instructions
1. INTRODUCTION
The NEXT K9-85 MCW is a pet-immune 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 immunity to pets weighing up to 38 kg (85 lb).
NEXT is a registered mark of Visonic Ltd.
The
advanced True Motion Recognition™ algorithm (patented)
allows the NEXT K9-85 MCW to distinguish between the true
motion of an intruder and any other disturbances which may cause
false alarms. In addition, Target Specific Imaging™ (TSI)
technology is employed for distinction between human beings and
pets.
An on-board motion event jumper determines whether 1 or 2
consecutive motion events trigger an alarm.
The NEXT K9-85 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.
• An optional version provides better protection for systems
compliant with DD243. After initial detection, the detector is
capable of 7 additional detections for a period of 5 minutes.
Further detection is possible only if no movement occurs during
the following 2 minutes. The detector will revert to the initial
state if there is no movement for an additional 5 minutes.
• 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

Visual Indications:
LED Lights for about 3 seconds upon transmission of alarm &
tamper messages and upon motion detection in the walk test
mode.
LED Flashes during the power-up stabilization period, or after
restoring (pressing) the tamper switch.
LED Does not light upon transmission of supervision
messages.
