360° Anti-Interference Infrared Sensor

Features

Intelligent Logic Detection

Equipped with sophisticated intelligent logic detection algorithms, the sensor effectively filters out false positives caused by non-human movements, such as pets, wind-blown debris, or temperature fluctuations. This ensures that only genuine intrusions trigger alerts, reducing unnecessary disruptions and enhancing system reliability.

True Temperature Compensation Technology

The integrated true temperature compensation technology allows the sensor to adapt to extreme temperature changes in its operating environment. Whether in freezing cold or scorching heat, the device maintains consistent detection sensitivity, eliminating performance gaps that could compromise security.

Anti-Interference Capabilities

Boasting dual anti-interference features—anti-white light interference and anti-radio frequency interference—the PA-618 remains unaffected by strong external light sources or radio signals. This makes it suitable for both indoor and semi-outdoor installations where environmental interference is common.

Fresnel Optical Lens

The sensor is fitted with a high-quality Fresnel optical lens that expands the detection range and improves signal focus. This lens design ensures comprehensive coverage of the protected area, capturing even subtle movements within the detection zone.

Flexible Installation & Output Options

Designed for ceiling installation, the PA-618 offers versatile placement to suit different space layouts. Additionally, it features selectable NC/NO alarm output, allowing seamless compatibility with a wide range of security control hosts and third-party monitoring systems.

SMT Process Manufacturing

Crafted using advanced SMT process manufacturing, the sensor boasts superior build quality, enhanced durability, and resistance to wear and tear. This manufacturing technique also contributes to its compact design, making it unobtrusive in any setting.

Bipolar Pulse Count Adjustment

Users can customize the bipolar pulse count to match specific security needs, adjusting the sensor’s responsiveness to movement. This flexibility ensures optimal performance in high-traffic areas or quiet spaces requiring heightened sensitivity.

Technical Parameters

Power Supply

The sensor operates on a standard low-voltage power supply, ensuring safe and energy-efficient performance. Its low power consumption design makes it suitable for long-term use without frequent battery replacements or high energy costs.

Detection Mechanism

Powered by a dual element pyro-infrared sensor, the device detects dynamic human movements by sensing changes in infrared radiation. This mechanism ensures precise identification of intruders while ignoring non-living objects or static heat sources.

Installation Specifications

Optimized for ceiling installation, the sensor features a compact, lightweight design that simplifies mounting. It can be installed in various ceiling types, with adjustable positioning to achieve maximum coverage of the protected area.

Environmental Adaptability

Engineered to withstand a wide range of environmental conditions, the sensor offers strong adaptability to humidity and temperature variations. Its robust construction ensures reliable operation in both dry and moderately humid environments.

Output Configuration

The selectable NC/NO alarm output provides flexibility for integration with security systems, allowing users to choose between normally closed or normally open connections based on their system requirements.

Self-Test Function

A built-in self-test function enables the sensor to perform automatic checks during startup, ensuring all components are functioning correctly. This feature provides users with confidence in the device’s reliability and reduces the need for manual testing.

Applications

Residential Security

Ideal for family residential areas and real estate villas, the PA-618 protects homes from unauthorized entry. Its discrete design blends with home decor, while its reliable detection ensures homeowners feel secure day and night.

Commercial Buildings

Suitable for shopping malls, office buildings, and retail spaces, the sensor safeguards valuable assets and ensures the safety of employees and customers. Its anti-interference features make it effective in busy, high-traffic environments.

Industrial & Warehouse Protection

Perfect for factories and warehouses, the sensor monitors large, open spaces where intrusions could result in theft or damage to equipment. Its 360-degree coverage and adjustable sensitivity adapt to the unique needs of industrial settings.

Public Facilities

Can be used in libraries, community centers, and other public facilities to prevent vandalism and unauthorized access after hours. Its low maintenance design makes it a cost-effective security solution for public spaces.

FAQ

How does the Passive Infrared Sensor PA-618 detect intruders?

The sensor uses a dual element pyro-infrared sensor to detect changes in infrared radiation emitted by human bodies. When an intruder moves within the detection zone, the sensor identifies the dynamic heat signature and sends an alarm signal to the control host.

Can the sensor be installed in outdoor areas?

While the sensor is primarily designed for indoor use, it can be installed in covered outdoor areas (such as porches or gazebos) as long as it is protected from direct rain, snow, and extreme weather conditions. Its anti-white light and anti-radio frequency interference features enhance performance in semi-outdoor settings.

What is the benefit of selectable NC/NO alarm output?

Selectable NC/NO (normally closed/normally open) output allows the sensor to integrate with virtually any security control system or third-party monitoring platform. This flexibility ensures compatibility with existing infrastructure, eliminating the need for costly system upgrades.

How does the sensor avoid false alarms from pets?

The intelligent logic detection algorithm is programmed to distinguish between human movements and smaller animals (such as cats or dogs). By analyzing the size and movement pattern of heat sources, the sensor filters out pet-related false positives.

Is professional installation required for the PA-618?

No, the sensor features a user-friendly ceiling installation design that can be completed by DIY enthusiasts. The package includes a mounting base and instructions, making installation quick and straightforward. For large-scale commercial installations, professional assistance is recommended for optimal coverage.
