Takex PR-5B User manual

This sensor is only suitable for indoor application.
This sensor consists of a transmitter that emits infrared beam and a
receiver that receives it.
As illustrated below, the infrared beam emitted from the transmitter
is reected in the direction of incidence and then enters the receiver.
A protection loop is formed in the route of the transmitter
reector receiver.
Whenever this loop is interrupted (if any object should interrupt the
infrared beam), it is detected and an alarm is initiated.

This sensor will provide long and dependable service when properly installed.
Please read this Instruction Manual carefully for correct and effective use.
Please note : This sensor is designed to detect intrusion and to initiate an alarm ; it is not a burglary-preventing device.

INSTALLATION
2PARTS DESCRIPTION
Detection activation of this sensor is off-delay (detection time + approx. 1.5 sec.).
For that reason, check protection coverage as the following procedure.
1. Hold the reector against the wall over the "X" mark previously made and check the operation LED on the PR-5B.
2. If the operation LED lights up, check the position where it goes off while moving reector slowly vertically and horizontally by sliding for positioning
tentative center of coverage. * (Fig 1 .) Move the reector as slowly as possible because it takes approx. 1.5 sec at least till operation LED goes off
though the reector comes in coverage. If moving is too fast, the PR-5B will not have time to rest and operation LED will not go off.
3. Check 4 positions (in every directions) where operation LED lights up while moving reector slowly outward from the center.
The center of these 4 positions is an actual
coverage center where reector should be
installed. * (Fig 2.) LED lights up at real time
when reector moves out of coverage (When an
alarm triggers.)
Important : A common mistake is made by holding
the reector in the hand in the air, when
trying to make the PR-5B set up.
This is extremely difcult to achieve.
PLEASE DO NOT ATTEMPT TO DO
THIS.
The following instructions will ensure a successful set up.
1. Select appropriate installation position and determine the best mounting height for application. (PR-5B shall face the direction to be protected.)
2.
Measure the distance from the oor to where the center of the PR-5B main unit will be located. Mark a small "X" on the wall at that point. (Measure and
mark the same distance from the oor on the opposite wall where the reector will be mounted. Ensure that both wallsare reasonably parallel to each other.)
3. Connect the 10.5-26VDC power input and alarm output wires to the appropriate terminal connectors at the rear of the PR-5B.
4. Fix the PR-5B securely to the wall using the "X" mark already made as the center reference on the wall.

Symptom
No alarm condition
Continuous alarm
Frequent alarm
with no intrusion.
Possible cause Remedy
①Breaker of control panel is
cut off.
(No voltage on power
terminals for sensor)
②Either sensor or reector is
not set in a correct direction.
③Disconnection or separation
of wiring between sensor
and control panel.
Infrared beam lter of the
sensor or the reector is
stained with water drops,
dust, or the like. (Alarm may
be given continuously in
severe cases.)
Moving objects in the protected
area. (like curtain, animal, etc.)
Clean the lter or the
reector with soft cloth.
Remove the moving objects
from the protected area.
Recover the breaker.
(Search the cause of cut-off
of breaker)
Correct the direction of the
sensor or reector with
reference to 4.
Installation of reector.
Repair the disconnection or
separation.
Reflector Reflector
Sensor Sensor
Where the sensor is installed on a
rough or irregular surface like
concrete, use a steel plate of about
2mm in thickness as foundation to
prevent misalignment of the optical
system.
Angle of incidence should be within 15 degrees.

Note: Install the reector within the range of 2'
(0.6m) to 15' (5m) from the sensor.
Note that the installation angle as well as
the position of the reector. (Fig. 5)
The reector has the function of
reecting infrared beam in the direction
of incidence within + / -15 degree of the
incidence angle.
When the reector is tilted, be sure to
use it within the above range.

Supply power to the sensor.
If the sensor faces the reector properly, the
operation LED does not light up.
If the LED lights up, refer to "4. INSTALLA-
TION" and re-adjust.
Next, interrupt the path of infrared beam
between the sensor and the reector with
beam shielding objects (human body or the
other objects which interrupts infrared
beam), and conrm that an alarm is given
and the operation LED lights up.
If the alarm stops when this object is
removed (LED off), the system is working
correctly.
Regular maintenance and inspection by
installer and frequent testing by user are
vital to continuous satisfactory operation of
any alarm system.
