Product Overview
The wireless transmission alarm system is composed of wireless transmit modules, detection instruments and receiving control cabinets. It realizes long-distance gas detection without field wiring at the detection side, bringing simple installation and operation. The receiving terminal uses a large touch screen to display gas concentration readings, and supports query of alarm records and trend curves.
Two wireless transmission modes are available: LoRa and 4G IoT to meet diverse application requirements. The LoRa solution delivers a transmission distance over 350 meters and incurs no network service charges. The 4G IoT option is suitable for ultra-long-distance transmission, available nationwide with no distance limit.
Product Features
The system adopts original imported sensors.
Equipped with an LCD screen, it delivers clear readings.
It supports intelligent temperature compensation, zero point compensation and fault alarm indication.
With wireless networking capability, detectors can connect to wireless controllers.
The smart solar charging system with built-in lithium battery removes the need for on-site wiring.
The product holds national explosion-proof certification.
The 4G IoT version integrates built-in GPS for real-time positioning.
Users can set up electronic geofences; an alarm will trigger once out of the predefined zone to prevent device loss.
Battery lifespan: rechargeable battery lasts 3 months on a single charge. Maintenance-free non-rechargeable batteries can operate for more than 3 years under normal conditions.
Total power consumption of the detector is less than 10 mW. It supports remote debugging, remote alarm mute and remote zero calibration.
The client platform enables users to check alarm records and historical trend curves.
Each gas detector of the 4G IoT version comes with 10 years of 4G data traffic. Customised packages are available upon request.
