NSTALLATION

3-1. NOTE

Detection range and installation
Distances between the Receiver and the Transmitter
It is not recommendable to install the units in this way (or direction). In case you do this installation, maximum detection range shall be half of the original detection range.
(This is to prevent the attenuation of beam by the edge of the cover.)
Alignment angle
Pole mounting
・Pole size should be 1 1/4”-1 7/8” (φ32-48mm). (Standard U.S. 1 1/4” or 1 1/2”pipe)

3-2. INSTALLATION METHOD

Detach the cover and the screw
Note When removing the cover, do not put your ﬁ ngers on the hood, whitch may cause damage.
1. Loosen the cover lock screw to detach the cover.
2. Turn the optical unit and open the waterproof plug.
3. Loosen the unit base lock screw and slide the mounting plate downward to detach the unit base.
Wiring
Use wires in compliance with the following conditions:

Wire diameter: φ4 – 7mm
When using any other wires than the above, seal the wiring port with a waterproof agent (silicon, etc.) to prevent water from coming in through the gap.
Number of wires: 3 (max.)
3 wires can be accommodated in a unit.
Lead-in wire should be as below.
*Wiring hole 2 needs to be punched with a screw driver, etc.

To have the wiring hole 3, wiring port needs to be cut with a cutter knife, etc. After inserting the wire, seal the wiring port with a waterproof material like silicon for leakage prevention.
Wiring guide should be as below.
Knockout needs to be opened with a nipper, etc.
1. Mount the unit base
  Connect the terminals with reference to “4. WIRE CONNECTION” and slide the unit base into the mounting plate from above, then fasten the unit base mounting screws to ﬁ x the unit base. Then, push in the waterproof plug up to the broken line shown in the ﬁ gure above.
2. Alignment and walk test
  Align the optical axis to the maximum receiving level according to “5-1.
  OPTICAL ALIGNMENT”. Then, check for the operation with reference to “6. WALK TEST”.
  Put the cover and tighten the cover lock screw.
  Make sure that the cover edge has reached the line prepared on the side of the unit base (See the ﬁ gure left)

WIRE CONNECTION

Connect respective wires to the terminals shown in the following ﬁ gure.

2. Wiring distance between power supply and detector
• Ensure that the wiring distance from the power supply is within the range shown in the table on the right.
• When using two or more units on one wire, the maximum length is obtained by dividing the wire length listed below by the number of units used.

Wire size	Power supply voltage
12VDC	24VDC

AWG22
(0.33mm2)| 1600ft.(500m)| 7800ft.(2400m)

“For UL Listed applications, the units shall be connected to a UL Listed control unit or Listed Burglar Power Supply capable of providing a minimum of 4 hours standby power.”

WARNING
Do not exceed the voltage or current rating speciﬁed for any of the terminals during installation, doing so might cause ﬁ re or damage to the devices.

ALIGNMENT

5-1 OPTICAL ALIGNMENT
The optical alignment is an important adjustment to increase reliability. In accordance with the procedure indicated in the items 1. and 2. in this chapter, make sure to align the monitor jack that monitor output nothing to attain the maximum level.

1. Rough alignment by viewﬁnder
• While looking through the viewﬁnder, turn the dial to make alignment in such a way that the other detector is at the center of the sights.

< Horizontal alignment >
| < Vertical alignment >

---|---
Turn the horizontal alignment dial by ﬁ ngers to make alignment| Turn the vertical alignment dial with a screwdriver to make alignment

For Horizontal/Vertical alignment, refer to the following illustration.

2. Checking of the illumination and Fine alignment Checking of the illumination of the Alarm Indicator
• After the rough alignment using the viewﬁ nder, check the light receiving status by the Alarm Indicator.

< Receiver >

Fine adjustment with monitor jack
• After checking the receiving level of optical axis by using the alarm indicator, make sure to make ﬁ ne alignment for both transmitter and receiver with voltmeter until it reaches maximum monitor output over “Good” level.

Set the voltmeter range to 5 The horizontal / Vertical alignment. to 10VDC and connect the voltmeter probes ⊕ and ⊖ to ⊕ and ⊖ of the monitor jack respectively.

Note When making the adjustment by the monitor jack, be careful not to intercept the optical unit with your hand, the tester pin cord, etc.

The relation between monitor output and receiving level of optical axis.

5-2 BEAM INTERRUPTION TIME
Initial setting is at 50ms for normal work.
According to the speed of a supposed target you select one speciﬁ c setting out of 4 steps.
Set the interruption time adjustment switches of the Receiver according to the speed of the human object to detect.

*5-3 4 SELECTABLE BEAM FREQUENCIES TF ONLY**

The selectable beam frequencies can be used to avoid unwanted crosstalk that can occur when using multiple photobeams for long distance or beam stacking applications.

To select between 4 separate beam frequencies, use the switch provided.
Make sure the receiver and transmitter that are facing each other are set to the same channel.
More than double stacked application is not possible.

Note Always switch the frequencies TWO channels apart when stacking units on top of one another (See following example) .
The upper unit is set on channel 1 while the lower is on channel 3.channels 2 and 4 could have also been used.

《EXAMPLE》

Long distance protection
Double stacked long distance protection
Perimeter protection
Double stacked long perimeter protection

WALK TEST

Make sure to check for the operation after installation.

Checking by the Alarm Indicator
< Receiver >
Make sure that the Alarm Indicator is OFF. If it is illuminated even when the beams are not blocked, make optical alignment again.
Walk test
Be sure to conduct a walk test (to block the infrared beam) at the following tree point:
A. In front of the Transmitter
B. In front of the Receiver
C. At the middle point between the
Transmitter and the Receiver If there are reﬂ ective things such as a fence, stop at the position C. once and make sure that the detector operates correctly.

Note If the Alarm Indicator is not turned on after beam interception, check for the operation with reference to “9. TROUBLE SHOOTING.”

SPECIAL FUNCTION * TF ONLY

7-1 ENVIRONMENTAL DISQUALIFICATION
D.Q. will send a trouble signal which indicates the adverse weather condition when the beam strength is being kept more than 40 seconds. adverse weather level > the beam strength > alarm output level

< Operating time chart >

< Example >
[D.Q. + Alarm]

Use the COM. terminal for both alarm output and D.Q. circuit.

[Alarm Output Cancellation]

By using external relay (N.O.), alarm output can be cancelled while D.Q. send signal.

*7-2 ALARM MEMORY TF ONLY**
This function is used to indicate which detector was activated with alarm memory LED while several detectors are installed in one site.
For ﬁ rst 5 minutes after the alarm output, the alarm memory indicator do not light up. Then the alarm memory indicator keep lighting up for 55 minutes. 5 minutes. Alarm memory record is cleared after alarm memory indicator is turned off.
