The ZX-212 inflammable gas detection and alarm controller belongs to the variety of smart alarm controllers and can be used with the SC610 inflammable gas detector. Normally, the controller is installed in a safe place where observation and maintenance is easy to realize. Signals obtained by the detector are transmitted to the controller in the 485 bus mode. The controller can display the current channel No., channel concentration, the alarm or failure status. When the concentration exceeds the preset alarm value, the controller can give an acousto-optic alarm and send control signals to prompt operators, thus helping to avoid accidents.
The ZX-212 inflammable gas detection and alarm controller can be extensively useful on many leakage-easy-to-happen occasions, indoors or outdoors, such as production, storage and usage of inflammable gases in the industry of chemicals, petroleum, metallurgy, oil tank farms, liquefied gas stations, spray-painting works, and gas transmission and distribution.
The design and manufacture of the ZX-212 inflammable gas alarm controller is in compliance with GB16808-1997, Technical Requirements and Test Methods for Combustible Gas Alarm Control Units, and relevant China national standards and regulations.
Ø The controller is easy to operate. Its interface is simple and friendly, offering most convenient operation to users.
Ø Providing abundant amounts of information to help operators to hold a full knowledge of the controller’s operation states.
Ø Capable of recording latest alarm messages, making accident tracking possible.
Ø The controller cabinet is small and can be mounted on wall simply and easily.
Ø Gas concentration is displayed by liquid crystal digits, clearly and visually.
Ø With only four buttons necessary to complete all operations, the button mode simplifies the operation.
Ø The power of the controller can be switched over between the main and the standby to make sure the controller can work well in case of an accident.
