68L steel cylinder is used to fill 45Kg of carbon dioxide per bottle.
Including: automatic fire extinguishing controller, CO2 cylinder assembly, release valve, backup power supply, remote release box, detector, safety valve, pressure signal transmitter, nozzle, check valve, CO2 jet warning light, temperature probe, etc.
Description: The bottle groups in each area are borrowed from each other to
achieve two fire extinguishing, and the rolling mill and the flue start at the same
Automatic fire extinguishing controller needs to meet：
lIt can receive fire signals and send out sound and light alarms to show the fire area.
lWith main alarm, zone alarm, de-sound switch and reset switch.
lSecondary alarm after manual release of sound and light alarm signal.
lThe sound intensity of the audible alarm must be higher than 85 decibels.
lUnder normal working conditions, the indicator light must be clearly visible from 3 meters away.
lThe delay device has a continuously adjustable delay function within 30
lIt has a switch key for primary and secondary fire extinguishing functions (the
primary and secondary fire extinguishing functions are exactly the same).v
lWith automatic and manual switching keys.
It can monitor and alarm power failures.
lEach zone has automatic, electrical buttons, manual mechanical start functions.
lWhen the main power is cut off, it can automatically switch to the backup power. When the main power is restored, it can automatically switch to the main power and charge the backup power.
lEquipped with voltmeter and power indicator (for standby power).
In the automatic fire extinguishing state, after any detector sends out a signal at a specified temperature, the controller should be able to send out fire alarm
signal, only after another group of detectors also send out the signal, the
controller can send out the fire extinguishing command.
21-2 Hand-operated electric fire extinguishing controller needs to meet
It can start the fire extinguishing system with the control panel by manual button.
lWith emergency braking function (within the delay range).
lWith power display function (equipped with power indicator).
lWith CO2 injection display function (equipped with injection indicator).
Mechanical emergency start needs to meet:
lIn the event of a power outage or a line failure, the CO2 remote control release box and release valve can be manually activated in a simple, reliable, flexible, and labor-saving manner.
lConcise and clear operating instructions are provided.
Standby power needs to meet:
lUse special battery pack (DC24V, 50Ah)
lAfter 24 hours of continuous work in the monitoring state, it can continue to work for 30 minutes under maximum load conditions.
