PGST PA-92R - User Manual

This document describes a wireless Passive Infrared (PIR) detector designed for indoor use, featuring low power consumption. The device utilizes a digital fuzzy logic infrared control system and an intelligent analysis algorithm to distinguish between interference signals and human movement, thereby preventing false alarms. It also incorporates temperature compensation and airflow technology to adapt to environmental changes. The detector is designed to be environmentally friendly, safe, and easy to install, automatically signaling low voltage to a connected GSM alarm system. It is suitable for various applications, including housing estates, villas, factories, warehouses, and office buildings.

Function Description

The PIR detector operates on a CMOS low-power consumption microprocessor, ensuring extended battery life. It includes built-in millions of codes and transmits digital wireless signals. A low voltage alert function is integrated to notify users when the battery needs replacement. The device features all-around automatic temperature compensation and intelligent logic analysis to minimize false alarms. It also offers protection against white light and high-frequency interference.

Usage Features

The device's LED indicator provides visual feedback on its status. A frequently flashing LED indicates that the device is in a self-checking state. A single flash signifies an alarm, while two flashes indicate that the device has completed its self-check and entered working mode. Three flashes signal a low battery voltage, prompting a low voltage alert message if connected to a GSM alarm system. The working mode can be configured as either "test mode" or "sleeping mode" via a jumper (J4).

The infrared sensor detects human body radiation; users should avoid touching the lens and keep it clean. Data bits can be set via jumper J2 to match the requirements of the alarm panel. Jumper J3 allows disabling the LED to enhance the detector's elusiveness. Jumper J4 determines the working mode: inserting J4 sets it to sleeping mode, while removing J4 sets it to test mode.

Upon pulling out the insulated tape, the device immediately transmits a 2-second wireless signal and then enters a 30-second self-checking period. After this, the working mode can be set via jumper J4.

In test mode, the detector detects movement every 2.5 seconds and transmits a wireless alarm signal upon detecting human infrared signals, preventing missed alarms. This mode also allows users to verify the installation height and angle, making adjustments as needed.

In sleeping mode, if the detector triggers four alerts within three minutes, it enters a dormant state to conserve battery power. It reactivates after three minutes of no alerts.

For coding, the alarm panel should be set to coding state. After installing the battery, the detector sends a wireless signal to the alarm panel. Moving a hand to trigger the device after self-testing will also send a wireless signal to the alarm panel.

Installation Guidelines

To ensure optimal performance, the detector should be installed away from areas with frequent temperature changes or fast airflow, such as windows, air conditioners, fluorescent lamps, heating apparatuses, refrigerators, ovens, stoves, or direct sunlight. To prevent interference and false alarms, avoid installing two detectors in the same zone.

The suggested installation height is between 1.8 and 2.2 meters above the ground, with the detection angle and distance adjusted by fastening the detector on its mounting bracket. The PIR detector is highly sensitive to lateral human movement but less sensitive to longitudinal movement. Therefore, it should be installed vertically to the human's walking direction.

Product Testing

After battery installation, the device undergoes a 30-second self-check and then enters test mode. Users should walk around the detection zone (from left to right or right to left) and observe the LED flashes to confirm normal operation. The LED indicator flashes once when human body movement is detected. The height and angle of the device should be adjusted to achieve the best detection range.

Maintenance Features

Troubleshooting steps are provided for common issues. If the LED fails to light up, users should check if the battery is installed correctly or if its power has run out. Additionally, they should verify if jumper J3 is inserted. If the LED flashes three times periodically, it indicates low voltage, and the battery should be replaced. If the wireless distance becomes shorter, it suggests that the battery is running out. If there is no response from the detector, users should check if the jumper cap J4 is set to sleeping mode.

The device is designed to comply with part 15 of the FCC Rules, ensuring that it does not cause harmful interference and accepts any interference received. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. If the equipment causes harmful interference to radio or television reception, users are advised to reorient or relocate the receiving antenna, increase the separation between the equipment and receiver, connect the equipment to a different circuit, or consult a dealer or an experienced radio/TV technician for assistance.
