Automatic fire extinguishing controller
CO2 cylinder assembly
Remote release box
Pressure signal transmitters
CO2 injection warning lights
Temperature probes, etc.
The bottle groups in each area are borrowed from each other to achieve two fire extinguishing, and the rolling mill and the flue are started at the same time.
Automatic fire extinguishing controller needs to meet
It can receive fire signals and send out sound and light alarms to show the fire area.
With main alarm, zone alarm, de-sound switch and reset switch.
The sound and light alarm signal can be alarmed twice after manual release.
The sound intensity of the audible alarm must be higher than 85 decibels.
The indicator light must be clearly visible from 3 meters away under normal working conditions.
The delay device has a continuously adjustable delay function within 20 seconds.It has a switch key for primary and secondary fire extinguishing functions (the primary and secondary fire extinguishing functions are exactly the same)
With automatic and manual switching keys.
It can monitor and alarm for power failures.
Each zone has automatic, electrical buttons, manual mechanical start functions.
When 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. Equipped with a voltmeter and a power indicator (for the standby power supply). In the automatic fire extinguishing state, after any detector sends a signal at a specified temperature, the controller should be able to send a fire alarm signal, only when the other group detects The controller can send out the fire extinguishing command after the signal is sent out from the device page.
The manual electric fire extinguishing controller must meet:
The fire extinguishing system can be activated by manual button together with the control panel.
With emergency braking function (within the delay range).
With power display function (equipped with power indicator).
With CO2 injection display function (with injection indicator).
Mechanical emergency start must meet:
In the event of a power outage or line failure, the CO2 remote control release box and release valve can be manually activated in a simple, reliable, flexible, and labor-saving manner.
Concise and clear operating instructions are available.
The backup power supply must meet:
Use special battery pack (DC24V/50Ah)
After 24 hours of continuous work in the monitoring state, it can still continue to work for 30 minutes under the maximum load condition.
