QB2000F single-point wall-mounted CO alarm detector (hereinafter referred to as detector) is a kind of fixed type detector that can be used continuously in operation environment to detect the density of combustion gas, oxygen, or poisonous gas.
The alarm detector adopt natural spreading method to detect the
density of the gas, and it use the imported electric chemical
sensor (flammable gas is catalytic combustion type) which has
excellent sensibility and receptivity; big liquid crystal screen
displays the density of the leaked gas real time and if the density
exceed the preset alarm point it will start the acoustic-optical
alarm or the exhaust system; international standard signal of
4-20mA can be directly connected into the factory DCS system, RS485
digital signal is connected with factory’s principle computer; the
device adopts embedded micro controlling technique, the Chinese
menu is easy to operate and the function is complete and reliable.
The performance of the whole device is among the best ones in
China.
Characteristics:
◆the device adopts advanced 16 digit ultra-low power consumption
embedded micro controller.
◆128*64 dot matrix ultra-large liquid-crystal display
◆user can set the alarm point by themselves
◆Chinese menu is easy to operate for domestic customers
◆displaying the time of fist alarm
◆real-time clock
◆modularized sensor can be changed
◆the automatic correcting function can decrease the measuring error.
◆500 pieces of alarm record can be stored automatically
◆standby battery can work more than 12 hours in the condition that
do not work (optional)
◆standard signal of 4-20mA can be directly connected into the
factory DCS system
◆RS485 digital signal is connected with factory’s principle
computer.
