Roll Block | PGST 433MHz Wireless Window & Door Sensor - Smart Security Magnetic Gap Detector

• 💥 Micro-Louver Magnetic Induction Matrix: Experience zero-latency separation detection. The integrated high-sensitivity internal reed switch tracks structural gaps within a 25mm to 35mm trigger threshold, instantly recognizing when the primary magnet separates from the sensor body.

• ⚡ Dedicated 433MHz Radio Protocol Grid: Reliable, interference-free transmission. Running on a dedicated 433MHz security radio frequency, this sensor circumvents congested 2.4GHz or 5GHz domestic Wi-Fi networks, ensuring stable line-of-sight signal transmission up to 120 meters.

• 🛡️ EV1527 Encoding & Universal System Sync: Seamless peripheral integration. Programmed with standard EV1527 wireless code variables and a 330K Ω resistance rating, the sensor pairs effortlessly with PGST security hosts like the PG103, PG106, PG107, or PG108 consoles.

• 🔋 Ultra-Low Power Consumption Architecture: Enjoy long-term standby intervals without maintenance anxiety. Drawing power from a DC 3V button cell battery, the internal board limits static standby current to a microscopic 10uA, triggering only during actual physical movement.

⚠️ Production & Quality Control Disclosures

To ensure total transparency and the absolute best network configuration, please review these key technical compatibility facts before adding this sensor to your layout:

• 📊 Standalone Host Interdependency Limits: This component is an accessory transmitter and cannot function as an independent, self-contained alarm. It requires connection to a compatible 433MHz security host receiver console to push smartphone application notifications or trigger active sirens.

• 🧩 Third-Party Host Compatibility Criteria: If pairing this sensor with a non-PGST 433MHz alarm host, ensure your receiver unit strictly matches the following technical parameters: an operating frequency of exactly 433MHz, an EV1527 integrated circuit format, and an internal resistance rating of 330K Ω.

• 🔌 Real-Time Battery Under-Voltage Tracking: The integrated firmware includes an active voltage safety monitor threshold set at 2.2V (±0.2V). When battery cell charge levels drop past this limit, the transmitter sends a low-battery status package to your central security console during system checks.

💡 Pro-Tip for Elite Gap Alignment Optimization: To guarantee a solid, error-free close seal and eliminate false alarms caused by minor wind vibrations, install the main sensor housing on your static window or door frame structure, and mount the smaller companion magnet directly onto the moving panel. Ensure the designated alignment notches on both housings face each other and sit less than 10mm apart when the entry point is fully closed!
