DS484Q/DS486Q | Installation Instructions | 1.0 Overview

1.0 Overview

1.1 Description

The DS484Q and DS486Q are photoelectric quad beam detectors that use four pulsed infrared beams to activate an alarm relay upon detection of an intruder. Both models contain a transmitter that emits an invisible infrared beam, and a receiver. If the beam is broken, the receiver signals an alarm. Multiple channel operation provides increased system flexibility by allowing multiple devices to be used near each other without cross-talk or other interference.

1.3 Features

1.3.1 100 Times Sensitivity Allowance

Stable operation is maintained even if 99% of beam energy is cut by environmental disturbances such as rain, fog, or frost.

1.3.2 Beam Power Control

Use this feature to select the appropriate beam intensity for the detection range. Controlling beam intensity minimizes the risk of reflection off nearby walls and cross detection with other detectors.

1.3.3 Beam Interruption Time Control

Use this feature to change the beam interruption time to best fit the application.

1.3.4 Using Multiple Transmitter-and-Receiver Sets

Up to four transmitter-and-receiver sets can be stacked.

1.3.5 Selectable Beams

The beams in the DS484Q and DS486Q are configurable into eight different combinations (two groups by four channels). These combinations can eliminate false alarms that can occur from cross-talk when multiple beams are stacked, or when the transmitter and receiver are separated by a long distance.

The diameter of the transmitted beam increases with increased distance between the transmitter and receiver. At distances that approach the maximum range, the beam might reach two or more receivers. Refer to Section 2.1.2 Beam Spread on page 5 for additional information.

DS484Q/DS486Q | Installation Instructions | 1.0 Overview

1.3.6 Selectable AND/OR Gate

The photoelectric intrusion detection system in the DS484Q and DS486Q provides alarm relay activation for different considerations. Use the DIP Switches to

Table 1: EDC BYPASS Switch States

Detector Status BYPASS Switch

select the required protection: AND gate – All four beams must be blocked

simultaneously to cause an alarm. This setting results in fewer false alarms caused by birds and other small animals.

Poor Environmental Condition*

OR gate – Either the upper or lower pairs of beams must be blocked. This setting can detect an intruder crawling on the ground.

1.3.7 Environmental Discrimination Circuit (EDC)

The Environmental Discrimination Circuit (EDC) sends a signal when maintaining stable operation becomes difficult due to environmental disturbances. The EDC detects the gradual loss of signal along the beam’s path because of dirt built up on the cover, or because of rain, fog, or snow. If the signal decreases by 95% over at least 4-seconds, the EDC activates the EDC LED (refer to Figure 3 on page 3) and relay. This indicates that something is partially blocking a beam, or that the covers need cleaning.

The EDC feature was not evaluated by Underwriters Laboratories (UL).

When either optical module is blocked for 3 or more seconds.

Figure 4: Receiver DIP Switches

When both optical modules are blocked for 3 seconds.

To use the EDC Bypass Switch, set the receiver’s DIP Switch 5 to ON or OFF (Figure 4). Refer to Table 1 for information about the functions and detector status.

∗ Poor environmental condition refers to difficulty in maintaining

stable operation due to environmental disturbances like fog or rain.

No alarm output is generated.

After the specified interruption time, the ALARM LED turns ON and alarm signal is generated.

If beams are blocked for more than 3 seconds, EDC LED turns ON, and EDC signal is generated.

BYPASS Switch ON

EDC LED turns on and EDC signal is provided through the normally-closed relay output at the receiver.

With the loss of beam energy, the ALARM LED lights but alarm signal is not generated (alarm relay is automatically shunted).

EDC LED turns on and EDC signal is provided.

If another optical module is blocked, the ALARM LED turns ON, but no alarm signal is generated.

After the specified interruption time, the ALARM LED turns ON, and alarm signal is generated.

EDC LED does not turn ON, and EDC signal is not provided.

Connect the EDC to a trouble circuit.

Check the system after the EDC relay activates.

2.1 Installation Considerations

Read the following information before installing, wiring, and performing regular maintenance on the equipment.

Do not install the detector:

• near trees and plants where falling leaves can block

the beam

• where intense sources of light and sunlight can

reflect directly into the receiver optics

A beam of light shining at a ±3-degree angle of each receiver can cause false

• on movable surfaces

• where subject to splashing water or sea spray

• beyond the maximum range of each model

• where strong electrical noise or radio frequency

interference occurs

• where strong vibration occurs

• in the presence of corrosive or explosive gas

Face upper and lower optical modules toward each other on the transmitter and the receiver.

alarms.

• Do not install or wire detectors during a

thunderstorm.

• Do not supply power until all wiring is

completed.

• Maintain power between 10.5 VDC and

28 VDC at all times.

• Do not disassemble or modify the base.

2.1.1 Beam Strength over Distance

The beam strength is best if used within the maximum range of the detectors. If used for shorter distances, excess beam energy reaches the receiver resulting in reflection off nearby walls and incorrect communication with other detectors.

2.1.2 Beam Spread

The beam spread is +0.7°. Refer to Figure 5 and Table 2

to determine the installation conditions.

4.1.3 Beam Group and Channel Setup

When installing only one transmitter and one receiver (a set), beam group and channel selection is not required. Leave the switches on the transmitter and receiver in the original (OFF) positions. Refer to Figure 17 on page 12.

The transmitter and the receiver have eight selectable beams. The beams are divided into two groups (Group A and Group B) of four beams each. The beams are referred to as channels (Channels M, 1, 2, and 3). Refer to Figure 16.

Figure 16: Beam Group and Channel

Organization

BEAM GROUP A CHANNEL M

CHANNEL 1 CHANNEL 2 CHANNEL 3

GROUP B CHANNEL M

CHANNEL 1 CHANNEL 2 CHANNEL 3

Channels 1, 2 or 3 can emit beams only when Channel M in the same group provides those channels with synchronized (synchro) wiring. Refer to Section

4.1.4 Synchronized Wiring on page 12. When installing two or more sets in the same group, set only the first set to Channel M. Set the remaining sets to Channel 1, 2, or 3.

One transmitter and one receiver facing each other are a set. In a set, each unit must have the same setting for group and for channel.

When installing two or more sets, use different settings for each set (transmitter and receiver) to avoid incorrect communication.

4.1.4 Synchronized Wiring

Synchronized (abbreviated “synchro”) wires are required when installing two or more sets in the same group by using the SYNCHRO terminal on each transmitter. Synchro wires are not required between the receivers.

The synchro wire should be more than 0.8 mm (22 AWG) in diameter, run no longer than 20 m (66 ft), and be wired only to the same group (Group A to Group A or Group B to Group B). Do not wire across groups (Group A to Group B).

Synchronized transmitters must use a common power supply.

The system does not activate when synchro wires are connected improperly, or if other unneeded wires are connected.

The POWER LED flashes when the required wires are not connected correctly.

When the POWER LED flashes, shut off the power and reconnect the wires correctly.

4.2 Alignment

4.2.1 Description

Precise, correct alignment is critical for these systems to operate effectively.

Aligning a paired transmitter and receiver requires a coarse, or visual, alignment followed by a fine alignment.

Coarse Alignment

In the coarse alignment, if the installed devices do not face each other directly, the upper optical module and the lower optical module on each device are manually turned toward the opposite device. Then the opposite device is viewed through the scopes on the upper and lower optical modules while the horizontal and vertical angles are adjusted, using the turntable and the adjustment screws. Refer to Section 4.2.2 Scope Alignment on page 14.

Fine Alignment

The detectors have three possible fine alignment methods: Voltmeter, Level LED, and Sound. Alignment interruption sheets (Figure 19) are used in all three procedures to cover all optical modules in the installation except the pair that are being aligned. Select a procedure based on the conditions and considerations of the specific installation. Refer to Table 9.

The first procedure (Section 4.2.2 Scope Alignment on page 14) is a visual alignment

and is not precise. Use one of the additional procedures to complete the alignment.

Table 9: Fine Alignment Considerations

Alignment Procedure Considerations

Voltmeter (Refer to Section

4.2.3 Voltmeter Alignment on

page 15.)

• Requires a voltmeter and a

screwdriver

• Works well at any distance

between the transmitter and receiver

• Requires repeated

observation of the voltmeter at the receiver

• Most accurate

• Might require two people

Level LED (Refer to Section

4.2.4 Level LED Alignment on

page 15.)

• Requires only a screwdriver

• More difficult to do when the

transmitter and receiver are installed far apart

• Requires repeated visual

observation of the level meter on the receiver

• Might require two people

Sound (Refer to Section 4.2.5

Sound Alignment on page 15.)

• Requires only a screwdriver

• Works well at any distance

between the transmitter and receiver

• Does not require visual

observation of the opposite device

• Difficult to do in a noisy

environment

DS484Q/DS486Q | Installation Instructions | 4.0 Setup and Alignment

For synchronized applications or stacked sets of transmitters and receivers, install

interruption sheets on all optical modules except the pair to be aligned.

10. Do one of the fine alignments. Refer to Table 9 on

page 13 to determine which procedure to use.

For the following procedures, make sure that all optical modules are covered with interruption sheets, except the pair to be aligned.

Remove the interruption sheets and close the covers when the alignment is complete.

4.2.3 Voltmeter Alignment

1. Insert voltmeter leads into the alignment check

terminals on the receiver panel. Refer to Figure 3 on page 3

2. Set the voltmeter scale to 10.0 VDC.

3. Use a screwdriver to adjust horizontal and vertical

adjustment screws on the transmitter and the receiver. Refer to Figure 21 on page 14.

4. Check the voltage reading and continue to adjust

the adjustment screws as necessary. In an ideal environment, the voltmeter value should be

3.0 VDC or higher. (The maximum voltage is 3.75 VDC.)

5. When the best voltage is achieved, the optical

modules are aligned.

6. Repeat the procedure for the other optical module

pair.

4.2.4 Level LED Alignment

1. Look at the Level Meter on the receiver. Refer to

Figure 23. When you begin this procedure the LEDs are off.

2. Use a screwdriver to adjust the optical modules.

Adjust the horizontal and vertical adjustment screws as necessary. Refer to Figure 21.

3. As more beam energy is received, each LED turns

on, flashes quickly, flashes slowly, and then turns off.

4. Continue fine tuning until the LEDs turn off.

• If outdoors, the alignment is complete when all

LEDs are off.

• If indoors, the alignment is complete when the

lower two LEDs are off.

5. Repeat the procedure for the other optical module

pair.

4.2.5 Sound Alignment

1. Set DIP Switch 6 on the receiver to ON. Refer to

Figure 23.

2. Use a screwdriver to adjust the optical modules.

Adjust the horizontal and vertical adjustment screws as necessary. Refer to Figure 21.

3. As more beam energy is received, the sound pitch

changes from low to high and from a continuous tone to a two beat sound.

4. Continue fine tuning until the buzzer is a two-beat

sound.

5. After the beams are aligned, set DIP Switch 6 to

OFF.

6. Repeat the procedure for the other optical module

pair.

DS484Q/DS486Q | Installation Instructions | 5.0 Walk Test

5.0 Walk Test

Walk across the beam path directly in front of one of the detectors. The ALARM LED should activate. If not, the beam interrupt time is set too low or the alignment is not correct.

Walk across the beam path in several locations between the detectors (Figure 24).Each time you cross the beam path, the ALARM LED should activate. If not, the beam interrupt time is set too low or the alignment is not correct.
