Gas Detection System Alarm Controller Bus System Multi-channels Gas Detector Controller 4-20mA RS485 Output

>>Overview

This product is a 4/8/16/32-channel gas alarm control panel. It consists of a universal metal enclosure, switching power supply, main board, interface board, and alarm units. The display section features 0.8-inch digital tubes that ‌sequentially show‌ gas concentrations for each channel, delivering clear visibility adaptable to various lighting conditions while indicating channel status. The keypad incorporates multiple high-quality buttons offering comfortable tactile feedback to enhance user operation.

The programming implements a high-security trigger mechanism: key recognition initiates upon pressing and completes upon release. Key signals shorter than 20ms are invalid, those between 20ms–3s register as standard presses, and signals exceeding 3s trigger long-press detection. The system provides audible and visual alarms with multiple relay outputs.

>>Features

◆ ‌Power Supply‌: AC 220V ±20%, 50Hz; Output: DC 24V; Power consumption <2W.
◆ ‌Dual Display‌: Digital tubes and LEDs ensure long lifespan, high brightness, and low power consumption. Clear visibility adapts to varying lighting, displaying concentration, units, alarms, and faults intuitively.
◆ ‌Embedded MCU‌: Features ST’s 32-bit high-performance, low-power microcontroller for rapid signal processing from detectors and real-time concentration display.
◆ ‌Audio-Visual Alarms‌: Visual alarms (optional); distinct audible alerts for faults, low/high alarms.
◆ ‌Relay Outputs‌: Up to 4 dry-contact relays with customizable configurations for diverse applications.
◆ ‌Flexible Detector Signals‌: Supports 4-20mA or RS485 (default: 4-20mA; RS485 optional).
◆ ‌Mute Function‌: Silences false alarms triggered by misoperation or testing.
◆ ‌Channel Lock (16-ch)‌: Allows locked-channel switching for real-time monitoring/testing.
◆ ‌Ergonomic Keypad‌: Large, high-quality buttons with optimal tactile feedback for enhanced operation.
◆ ‌Robust Enclosure‌: Simple waterproofing between door and body; smooth-finished metal shell for touch comfort and pressure resistance.
◆ ‌Ingress Protection‌: Water/dust-proof cable glands secure wiring entries.
◆ ‌Wall-Mounted‌: Easy installation/removal; optional brackets available.
