GN9000-S
Gas Alarm Controller, sample & deal with the signal
of 4¡«20mA or Mod-bus from detectors,transform the signal
to consistency of gas around detectors,display the value
of gas consistency & all kinds of system status on
LED,give out alarm signal of light & sound ,and output
linkage controlling signal if fault or alarm occur.
GN9000-S can work not only with GN8010-C, GN8010-E, GN8020-C,
GN8020-E detectors, but also with every kind of instruments,
which output standard 4-20mA current. So GN9000-S can
be applied to the large centralized monitor system and
our company can customize GN9000-S Gas Alarm Controller
according the requirements of customers. |
