China CAATM CA-2100M Industrial 3-Channel Wall-Mounted Gas Alarm Controller from Reliable Suppliers and Factory
Product Description
The combustible gas alarm controller is wall mounted and used to connect combustible gas detectors, such as the CA228 series, ultimately forming a combustible gas detection and alarm system. This product has 3-channel external control ports, allowing users to freely choose the access port for attaching detectors and perform on-site detection and alarm through simple settings. This system is mainly used for detecting combustible gas and displaying the detected gas concentration (% LEL). When the concentration of a certain gas on site is higher than the set alarm value, the output contact is closed to drive a series of alarm actions, such as alarm, exhaust, disconnection switch, etc.
The power switch and circuit board of the host each carry a layer of protective circuit, providing dual protection and greater safety. The host comes with a backup power supply, which can ensure the continuous operation of the system when the power is cut off. In addition, the product is equipped with a black box, ensuring no data loss in case of power failure. The product can display the working status of the detector in real time, with a fault self-checking function. Once a fault or gas leak is detected, it will immediately prompt.
Features specialized protective circuits on both the power switch and circuit board for enhanced operational safety.
Equipped with a built-in backup power source to guarantee uninterrupted system operations during outages.
Integrates a dedicated black box module preventing critical system data loss during unexpected power failures.

Frequently Asked Questions (FAQ)
Q What is the purpose of the combustible gas alarm controller?
The combustible gas alarm controller is a wall-mounted unit used to connect compatible combustible gas detectors (such as the CA228 series) to form a complete detection and alarm system that monitors and displays gas concentration levels (% LEL) in real time.
Q How many external detectors can be connected to the controller?
The controller is equipped with 3-channel external control ports, allowing users to choose the access ports freely for attaching detectors and configuring the setup on-site.
Q What actions are triggered when gas levels exceed the safety threshold?
When the gas concentration exceeds the preset alarm value, the output contact closes automatically to trigger designated actions such as sounding the alarm, turning on exhaust ventilation, or activating a disconnection switch.
Q Does the system lose data or stop working during a power outage?
No. The host includes a backup battery power supply (DC3.7V/2200mAh*2) to ensure continuous operation, and it features a built-in black box system that prevents any data loss in the event of a power failure.
Q What safety and self-diagnostic features does this controller offer?
The controller features dual protective circuit layers on both the power switch and the circuit board. It also provides real-time status monitoring and a fault self-checking function that triggers immediate prompts if any faults or gas leaks are detected.
