Takex PR-5B Instruction Manual

Thank you for purchasing the TAKEX product.
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.

PRODUCT DESCRIPTION
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.
infrared beam
Whenever this loop is interrupted (if any object should interrupt the
infrared beam), it is detected and an alarm is initiated.

INSTALLATION
4-1
Installation of sensor unit
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.

Installation of reflector
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.
