Product introduction
KB-2000B series alarm controller system for combustible gas detection is a new type design according to the national standard; this alarm controller is mainly applied to petroleum & chemical industry, medicine and city gas, pipeline of delivery for oil gas and the transfer station etc fields with the combustible gas.
This equipment applies digit technique with high IC smart instrument. It’s controlled by the computer from signal collection, alarm control to alarm display; in the system applies specified time clock chip so that the precise timing when cut of the power and save the alarm signal for 100 records, all the information including time, concentration, alarm setting point, time of alarm and records are displayed by 4 units LED screen.
This alarm controller can monitor the detector working condition from 1 to 10 circuits and can display the status of working, fault, low concentration alert and high concentration alert. It can sound different audible signals between fault and alarm so that reminder the operator to handle it by way of keyboard, adjustable time and alarm concentration and it has the functions of self-checking, erasure and resetting.
The standby battery is available and can still work more than 2 hours when cut off the power.
