1. Introduction
DM-448R series is a viewfinder passive infrared detector which adopts digital
micro-processor with energy-pile up-logical process, random dynamic time
split technology. The PIR parts adopt precision column lens to upgrade
receiving effect, higher sensitivity but lower false alarm. With the buit in
battery and the exclusive electricity save up model, it can be used for a long
time of as twice as the other brand detectors.

Start the test at least 2 minutes after connecting power supply 2. Walking breadthwise at the remote and of the detection coverage at the speed of 0.75m/s within 3m, then will trigger the detector and the LED indications 2-3seconds.
- Page 4 5 Solution of usual problem Conduct walking test in detection coverage, but no alarm output Discomece the alarm output If trouble with control Remove the cover to LED indicates but no to check if shot circuit panel, contact suppliers check if the relay be on signal outputs existime Please clear the trouble of short-circuit...
