2. Fire hydrant equipment
(1) It consists of a water gun, a water hose, and a fire hydrant. The pressure stabilizing device is m*nly composed of a small imported *r pressure tank, a fire hydrant pump unit, a fully automatic sprinkler pump unit, pipe valve accessories and a control cabinet, among which the fire hydrant pump unit constitutes a fire hydrant sprinkler system.
(2) Water supply network, consisting of an inlet pipe fire m*n pipe, a fire riser and related valves and valve parts. The water supply network and related valve accessories are made of materials required by the fire system water supply specification to meet the pressure bearing capacity specified by the fire water supply system;
3. Power control panel (all st*nless structure)
provides AC power: three-phase AC 380V 50Hz, with overcurrent protection
4. Fire alarm controller (linkage type)
5. Fire display panel
6. Detector

7. Input module, control module Input module
M*nly used for signal detection such as pressure switches, and control module is m*nly used for linkage equipment such as water pumps.
8. Manual alarm button
When a fire occurs, press the organic glass sheet, the fire alarm light of the button will light up, and send a fire alarm signal to the controller at the same time;
9. Fire hydrant button
When a fire occurs, press the pressure controller to alarm, light up the fire alarm indicator light (red), and output a set of external control empty contacts at the same time. When starting the fire pump, connect the pump start answer signal, the pump start indicator light up (green), and when resetting, slide down the sliding cover and press the reset button.
10. Sound and light alarm, alarm bell
When a fire occurs on site, after receiving the control signal, a strong sound alarm signal is issued to remind the on-site personnel to pay attention.
11. Electronic encoder
Complete the encoding of on-site equipment, change of equipment type and sensitivity, etc.
12. Broadcast recording and playback unit
Fire broadcast recorder and player, broadcast ceiling speaker
13. Power amplifier unit
Fire constant voltage power amplifier, background sound source power amplifier
14. Fire telephone system
Bus telephone communication panel, telephone extension, telephone module, etc.
15. Gas fire extinguishing system
The gas fire extinguishing system model includes fire linkage equipment such as smoke detectors, manual alarm buttons, sound and light alarms, deflation display screens, manual and automatic conversion switches, etc., to realize the alarm function of communication linkage with the fire sprinkler alarm host.
16. Virtual simulation software for electrical installation of building buildings and intelligent buildings Based on unity3d design, users can choose different sizes of interactive interfaces according to computer configuration, and can choose six levels of image quality. The model in the software can be rotated 360°, enlarged, reduced, and translated. There are assistant prompts during the use of the software, as follows: A. Wet alarm system 1.
