1.5m
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.

3.5 The code way of detector and the control panel.
Code setting:
Install the battery insulation slice, the LED gives indication..
Please do code program to the alarm control panel at this time. After the
setting of the control panel tamper, press the dismantling switch, Then
the detector will generate deep to indicate successful operation.
Press this switch for code setting
3.6 How to change battery
When the detector batlery is weak, it will send out single
to the control panel, at the same time, the detector
flashes indicating at you need to change battery for the
detector. Draw the PCB board; follow the steps as below to change 4
new battery. ( as right picture ).
3.7 Setting of detection angle
When installing with a swivel bracket
(optional) .please refer to the right
diagram, to ensure the desired
(overage and feature).
At this angle, detection
angle is smallest, sensi-
tivity is highest. Loss pet
immunity function.
At this angle, detection angle is
largest, Lower section sensitivity
is low. Pet immunity up to 20Kg
At this angle, sensitivity
is in middle. Pet immun-
ity up to 10Kg
3.4 Instruction of code switches
1. NO .1switch is for event mode, when set “OFF”, the detector will
alarm when detecting any movement follow input the enacted
directed ;when set “ON”, when it detect movement following the
enacted directon, ut won’t alarm at once, until detect continuous
and keeping on movement, it will alarm (fit for room without passage)
2. NO .2 switch is LED switch, LED light when setting “ON”,during
working
3. NO .3 switch is for direction distinguish, when set “ON”, this funtion
available; when “OFF” ,any movement from any direction will trigger
alarm
4. NO .4 switch is for direction choose, left/right fit for different
surrounding
1.event mode switch
2.LED switch
3.Direction distinguish switch
4.Direction choose switch
1. Start the test at least 2 minutes after connecting power supply
3 .Testing in different direction to confirm the two boundaries of the
coverage, ensure the detector is appoint to the central desired area.
4. At 6m away from diliclor , raise slowly your arm and reach
into the detection zone, mark the lower limit of PIR detection. Do
the same step to confirm the upper limit.
5.the center of detection zone should not uphill incline. To obtain a
good detection range , please adjust the vertical detection range, en-
sure the detector is in a correct position.
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.
6. After MW sensitivity or detection angle are adjusted, walking test
must be performed according to the above steps.
: after charge or the temper proof switch been pressed, the detector do self checking for 30 seconds then it get a period time
of 6 minutes for test. Within the test period, the human body moves according to the set direction until the system alarms, then
the indicating light lights and sends out the wireless alarm signal.
: after the testing period of 6minutes, it is the working period. Within this period, the human body moves according to the set
direction (such as enter into the room), if the LED ON is opened, then the indicating light lights and sends out the wireless
alarm signal. Then close the alarm, and test to see if any body is moving, until to the set alarm start up time, the system does
not detect the body movement, and confirmed to be away, then the detector can be started again.
When the human body moves against to the set direction (such as leave the room), the system does not alarm, Then close the
alarm, and test to see if any body is moving, until to the set alarm start up time, the system does not detect the body movement,
and confirmed to be away, then the detector can be started again.
After the reposition of the dismantle proof and magnetic switch on the detector, you will then get a period time6 minute for test. Within this time,
after the finish of automatic test, you can arrange the walking test. 6 minute later, the system enters into the working period. After one time alarm
within the working period, the system will check if there is any non-human activity for 140 seconds. Only after confirming that there is no human
activity for 140 seconds continuously, the detector will then start up the detecting model.

Special notice:

Working period
3.10 Perform walking test to the detection area: install the cover and close the fasten part
(refer to the right diagram)
Important mention: Motion test shall be performed at least one time each
week in order to guarantee that each detector can keep excellent function.
Even the most sophisticated detcetors can sometimes be defeated or may fail to warn due to :DC power failure/improper connection, malicious mask-
ing of the lens,tampering with the optical system, decreased sensitivity in ambient temperatures near that of the human body and unexpected fail-
ure of a component part.The above list includes the most common reasons for failure recommended that the detector and the entire alarm system be ch-
ecked weekly, to ensure proper performance.An alarm system should not be regarded as a substitute for insurance. Home & property owners or renters sh-
ouldbe prudent enough to continue insuring their lives & property, even though they are protected by an alarm system.
