Product Detail

Product Description

The combustible gas alarm controller is wall-mounted and designed to connect combustible gas detectors, such as the CA228 series, forming a highly reliable gas detection and alarm safety system.

This product features 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. The 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, and disconnection switches.

Dual Protection: The power switch and circuit board of the host each carry a layer of protective circuit, providing dual protection and greater safety.

Backup Power Supply: Comes with a built-in backup power supply to ensure continuous operation of the system when the main power is cut off.

Black Box Storage: Equipped with an integrated black box to ensure no data loss in the event of a sudden power failure.

Self-Diagnosis: Displays detector working status in real time and features a fault self-checking function with immediate prompts upon detecting faults or gas leaks.

Frequently Asked Questions

What detectors are compatible with this combustible gas alarm controller?

The controller is designed to connect to combustible gas detectors, specifically configured to pair seamlessly with models like the CA228 series to form a complete detection and alarm system.

How many detectors can be connected to the controller?

The controller features 3-channel external control ports, giving users the flexibility to choose and configure the access ports for attaching detectors.

What happens if the main power supply goes out?

The host is equipped with a built-in backup power supply (DC3.7V/2200mAh*2) that ensures the system continues to operate during a power outage. Additionally, the integrated black box prevents any data loss during power failures.

What external actions can the controller trigger upon an alarm?

When gas concentration exceeds the set alarm value, the output contact closes to trigger external safety actions, which can include alarms, starting exhaust fans, or activating disconnection switches.

What is the transmission distance and communication mode of this device?

The controller communicates via RS485 wired transmission, supporting a maximum transmission distance of up to 1500 meters.
