Each core component in the fire extinguishing system can be flexibly matched with each
other to create a system that meets the fire extinguishing requirements of different levels
in a single container or combined containers.
1.2 Components
Gas Extinguishing Controller
A gas extinguishing controller provides the following functions:

Detects and reports composite fire alarm signals in dual loops. It can be connected to the
emergency startup button, which ensures that the system operation is under control in
case of an emergency or during onsite equipment maintenance.

Restarts automatically after a fault is rectified.

Provides a port for the gas release confirmation signal (reporting pressure values).

Generates single and composite fire alarms, drives gas release indicators and audible and
visual alarms, and controls alarm bells.

Provides an independent output port for the solenoid valve driver and supports 3 A, 24 V
solenoid valve (electric detonator) startup current.

Detects the open circuit fault of the input loop and the short circuit and open circuit of
the output loop (in active output mode).

Provides the intelligent monitoring, and overcharge and overdischarge protection for
standby batteries.

Adopts the low-power consumption design, and supports at least 48-hour consecutive
operation for the backup power.

Provides password lock protection for the keypad to prevent misoperations.
Table 1-2 lists the specifications for the gas extinguishing controller.
