Gas Alarm Controller 

l  Three-line signal transmission, 19” standard 3U disk-type metal-structure frame, installed in a cabinet (wall-mounted type

    may be custom-made), anti-FRI/FMI, capable of monitoring up to 1,000 points after being combined

l  Independent card insertion design, optional channel card, master control card, power card,

    and standby power supply

l  Master card and channel card can be set respectively but display synchronously. Master card

    has a large LCD screen (display in Chinese) and Chinese menu. Display and operation are

    more convenient and faster.

l  Channel card can work independently, with an independent menu. Thus even if the master control or other channel cards go

     wrong, this channel’s gas monitoring will not be affected.

l  Channel card has many types of output, good for interlinking external control equipment and integrating them to upper control

    system (e.g. DSC, PLC, etc.).

l  Automatic trouble monitoring

l  Note: for trouble A and B, the controller can indicate their location. For trouble C, D, and E, the controller can indicate their type.

l  Interlinked output

l  Capable of keeping alarm records, trouble records, and start/shutdown records respectively

l  RS485 communication function is available

l  Power supply shift function
