DS484Q/DS486Q Installation Instructions EN Quad Beam Photoelectric Detectors
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.

DS484Q/DS486Q | Installation Instructions | 1.0 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 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. OR gate – Either the upper or lower pairs of beams must be blocked.
DS484Q/DS486Q | Installation Instructions | 2.0 Installation . 2.1.1 2.0 Installation 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 alarms.

Choose an appropriate mounting location for the system. Install poles with a clear line-ofsight between the transmitter and the receiver. 2. Loosen the transmitter’s cover mounting screw and remove the cover. Refer to Items 3 and 17 in Figure 1 on page 2. 3.

Back-to-Back Pole Mounting Make sure that the units are aimed so that the transmitter and the receiver in the same set are aligned with each other. 2.2.2 1. 2. With spacers between the two units, mount the transmitter and the receiver back-to-back. Refer to Figure 8. Use nuts and bolts to attach each unit firmly to the pole. Figure 9: Installation Wall Mounting Refer to Figure 9 for Steps 1 through 7. 1.

DS484Q/DS486Q | Installation Instructions | 4.0 Setup and Alignment . 4.2 Alignment 4.2.1 Description Precise, correct alignment is critical for these systems to operate effectively. 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.
DS484Q/DS486Q | Installation Instructions | 4.0 Setup and Alignment 4.2.2 Scope Alignment 1. Apply power to all transmitters and receivers in the installation. 2. Select a transmitter and receiver pair to align. 3. For coarse tuning, rotate the turntable on the upper or lower optical module of the transmitter horizontally to face the receiver. 4. Look into the left or right viewfinder of the optical module to see the image reflected through the scope aperture.
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.
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.
DS484Q/DS486Q | Installation Instructions | 6.0 Stacking Information . 6.0 Stacking Information When stacking two or more sets, use the group and channel settings shown in Figure 25. The correct DIP switch settings are shown for each transmitter and receiver.
DS484Q/DS486Q | Installation Instructions | 7.0 7.0 Troubleshooting Troubleshooting If the system does not operate as expected, check for the following conditions. The input voltage is between 10.5 VDC and 28 VDC at the terminal on the transmitter and on the receiver. The loop resistance of the alarm output is less than 100 Ω. The monitor LED on the transmitter is ON. The ALARM LED on the receiver is ON when both upper and lower beams are simultaneously adjusted for the beam interruption time.
