Optex FTN-ST Compact Outdoor Dual PIR Detector User Manual

1. Introduction and Overview

The Optex FTN-ST is a compact outdoor dual Passive Infrared (PIR) detector designed for reliable motion detection in various outdoor environments. This detector utilizes advanced technology to minimize false alarms while providing accurate detection over specified ranges. It is suitable for applications such as monitoring driveways, garages, and gardens.

2. Safety Information

Please read and understand all safety instructions before installing or operating this device. Failure to follow these instructions may result in injury or damage to the product.

• Electrical Safety: This device operates on a corded electric power source. Ensure all wiring is performed by a qualified professional and complies with local electrical codes. Disconnect power before installation or servicing.
• Mounting: Mount the detector securely to a stable surface to prevent it from falling. Ensure the mounting location does not obstruct the detection area.
• Environmental Conditions: While designed for outdoor use, avoid installing the detector in locations subject to extreme temperatures, direct sunlight, or heavy vibrations that could affect performance.
• Maintenance: Do not attempt to open or repair the device yourself. Refer all servicing to qualified personnel.

3. Package Contents

Verify that all items are present in the package before proceeding with installation:

• Optex FTN-ST Dual PIR Detector Unit
• Mounting Hardware (screws, anchors)
• Instruction Manual (this document)

4. Setup and Installation

The FTN-ST detector is designed for wall mounting and requires a corded electric power source.

4.1 Choosing a Mounting Location

Select a location that provides an unobstructed view of the desired detection area, such as a driveway, garage entrance, or garden path. Consider the maximum detection range of 16.4 feet (5 meters) and the adjustable detection patterns (16.5' x 3.3' or 6.7' x 3.3'). Avoid aiming the detector directly at moving foliage, reflective surfaces, or heat sources that could cause false activations.

4.2 Mounting the Detector

1. Carefully open the detector casing to access the mounting holes.
2. Position the detector on the chosen wall and mark the drilling points for the mounting screws.
3. Drill pilot holes and insert wall anchors if necessary.
4. Secure the detector to the wall using the provided mounting screws. Ensure it is firmly attached.

4.3 Wiring and Power Connection

Connect the detector to a suitable corded electric power source. Refer to the internal wiring diagram (if present within the unit) for specific terminal connections. Ensure proper polarity and secure all connections. It is recommended to have this step performed by a qualified electrician.

4.4 Adjusting Detection Area

The FTN-ST features dual PIR elements and adjustable detection patterns. Consult the internal adjustment mechanisms (often small dials or switches) to set the desired detection range and pattern (e.g., 16.5 feet long by 3.3 feet wide, or 6.7 feet long by 3.3 feet wide). Test the detection area by walking through it to confirm coverage and sensitivity.

5. Operating Instructions

Once installed and powered, the Optex FTN-ST detector will continuously monitor its configured detection area. When motion is detected by both PIR elements simultaneously within the set pattern, the detector will activate its output, typically signaling to a connected alarm system or device.

• Power-Up: Upon initial power-up, the detector may undergo a brief stabilization period (e.g., 30-60 seconds) during which it may not detect or may show a constant activation. This is normal.
• Detection Indicator: Many detectors include an LED indicator that illuminates upon detection. Observe this LED during testing to verify proper operation.
• Sensitivity: If the detector is too sensitive (false alarms) or not sensitive enough (missed detections), refer to the adjustment section in the installation guide to fine-tune the sensitivity and detection pattern.

6. Maintenance

Regular maintenance helps ensure the long-term reliability and performance of your Optex FTN-ST detector.

• Cleaning: Periodically clean the detector's lens and casing with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the lens is free from dirt, dust, spiderwebs, or insect nests that could obstruct detection.
• Inspection: Annually inspect the mounting hardware and wiring connections for any signs of wear, corrosion, or loosening. Tighten screws as needed.
• Environmental Check: Ensure that no new obstructions (e.g., growing plants, parked vehicles) have entered the detection area that could cause false alarms or block legitimate detections.

7. Troubleshooting

If you experience issues with your FTN-ST detector, refer to the following common problems and solutions:

If the problem persists after attempting these solutions, contact Optex customer support or a qualified technician.
