Explain:

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.

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).
