Before using, read this instruction manual thoroughly for proper installation procedures.
[!] CAUTION
BE CAREFUL NOT TO BE STRUCK BY THE DOOR
This product is a door activating non-contact sensor which is to be mounted to/into the transom of an automatic door or to
the ceiling. Do not use it for other applications.
D etection Area
The detection area refers to the space where the sensor b ody is receiving infrared rays.
D etection Method of O P-08C
This product outputs a signal when there is a difference in temperature between the floor surface of the detection area and
an entering person.
Actual D etection: D etection may be difficult in the following cases:
-When the floor temperature has increased to a point where there is little difference between the person and floor
surface.
-When someone approaches the door from a direction other than the front.
[!] ATTENTION
* Do not install the OP-08C beyond a distance of 4 m.
The sensor may not be able to detect a human body at distances greater than 4 meters.
* Be sure to use a beam switch in combination with the OP-08C to provide a back-up safety device.
Even if there is a person standing near the door, it may start closing.
* Affix the accessory area masking seal properly. If it is not affixed properly, sensitivity will be reduced dramatically
and an entering person may be struck by the door.

[!] ATTENTION
WATCH OUT FOR THE DOOR
Do not use the OP-08C to detect the objects (push cart, etc.) other than human bodies.
The OP-08C must recognize a temperature change to activate. A push cart may or may not have the required temperature
change to activate the sensor.
N ote: This p roduct d etects only changes in temperature and will not d etect a m otionless object!

< Caut ion >
This p roduct uses a m ethod of detecting the change in
temperature w hen a person enters the detection area.
A ccording to the background temperature, the detection
s ensitivity may b ecome higher or l ower.
Further, b ecause only changes in temperature are detected,
a person w ho is not moving will not be detected.

In this product, it is possible to change between the wide & deep d etection area
and standard detection area by inserting the lens. When shipped from the factory,
the product is set to the standard detection area.

INSTALLATION
Installing the main body
(1)Affix the mounting template to your desired position on the transom or ceiling
(mounting height within 4.0m).
(2)Drill mounting holes (Ø 3.4 mm) as indicated on the mounting template. If
concealed wiring is preferred, drill a wiring hole (Ø 8 mm.) After drilling holes,
remove the mounting template.
(5)Connect the connector for the main body to that of that wiring cord. To disconnect
them, press both knobs and pull them apart.
< Connecting the Connectors >
Insert the connectors deeply into each other. Otherwise, the OP-08C may
malfunction due to a contact failure.
(4)As shown in the left figure, remove the housing cover. Using the accessory
mounting template, affix the main body. Attach the main body to the transom,
leaving about 10 mm. of the screws's threads exposed.

< Precautions for M ounting >
- Do not place swaying objects, such as a potted plant, flag or banner in the
detection area. The sensor may not function properly.
-When using wiring knockout, be sure to install the OP-08C in a location
protected from rain. If exposed to rain, water may enter the housing and
damage the device.
(3)Connect a wiring cord to the door controller.
N ote that the wiring method differs depending on setting of the
r elay inversion switch.
< When the relay inversion switch is "Fail-Safe" >
Install the main body in such a manner that the connector can be connected easily.

Operation check
Check the operations in the following order.
( 1 ) Make sure that the power is turned on. (The power/operation indicator lamp is
illuminated).
( 2 ) After turning on the power, this product will not be activated for about 20 seconds
due to the required warm up time. (The power/operation indicator lamp is illuminated).
( 3 ) After the warm up time, enter the detection area to make sure that the sensor
functions properly. (When it functions, the power/operation indicator lamp is turned
off.)
Maintenance
- When the OP-08C becomes dirty, dip a cloth in neutral detergent and wipe it lightly.
Do not use any organic solvents such as thinner, benzine, because they may damage
the surface of the product.
Do not directly wash the sensor with water. Water may enter inside and damage the
device.
- Never disassemble or repair the equipment. There are no user servable parts.
- Handle carefully so that you do not damage the lens. If the lens is damaged, the sensor
may not function properly.
Problem Possible cause Solution
Does not function 1 . Disconnected or defective connection. 1 . Check the wiring and connector, and
correct the defect, if any.
Does not operate from 1 . Insufficient sensitivity. 1 . Set the sensitivity switch to a higher level
time to time
2 . Passing of a push cart, etc. 2 . The OP-08C may have difficulty detecting
objects other than human bodies.
Operates by itself 1. There is a moving object such as flag, banner, potted 1 . Move the object outside the detection area.
plant in the detection area.
2 . Passing of a dog or cat. 2 . The OP-08C detects its passage because
there is a change in temperature with
respect to the floor surface.
