Attention for installation:
- Because this wall mounted fixed aerosol fire protection system device is need to install on the wall or on the top of ceiling, and each device will be several tens of kilograms in gross weight, so when install it take care and make sure to firmly fix the bracket and screws.
- Better to Install it at least 1/2 high of the room height.
- Make sure the left side discharging outlet and right side discharging outlet without any obstacles.
Why we recommend of wall mounted aerosol for market:
Wall mounted aerosol is mostly install in computer rooms, data processing rooms, telecommunication rooms and other buildings, and in china we have many cases to install it in underground Integrated Pipe Gallery, which is a national projects in china.
Also it is cover more spaces and space saving to install, some protection zone will need to require a device which is a space saving device.
And aerosol extinguishing device is with very high extinguishing ability.
Safety Warning!
User should set warning sigh in the following obvious locations, the words on the warning sign suggest like follow:
- inside the protection zone: “WARNINGS! This is S type aerosol fire extinguishing device protection zone, if you hear there is a fire alarm at site, please escape immediately”.
- At location of the manual call point: “WARNING, When press down the manual call point button, please make sure there is no people at site”.
- Outside the protection zone: ” This protection zone is protected by aerosol fire extinguishing systems”.
Device Maintenance
to ensure of the reliability of hot aerosol fire extinguishing device, we should establish a complete regulations for equipment inspection and maintenance, and make operation norm; the qualified inspector should inspect it and make a record regularly.
During the maintenance period, the inspector must do inspection job in accordance with relevant standards and specifications.
1. Daily Maintenance (When device is being in use)
a. make sure the protection zone and fire alarm system control rooms are clean, dry and well ventilated.
b. make sure the surface of aerosol device and fire alarm control panel is without dust.
c. check the nameplate of the aerosol device, warning sign are intact, and check outlet of aerosol device is not blocked.
d. check whether the fire alarm system is with fault or not, or check whether it have activation problem or not; if find out any of above problem, then please check and resolve it in time.
2. Yearly Maintenance
- Protection area opening situations,aim of the protection area, protection types, quantities and distribution of combustibles, these factors should in accordance with fire protection standards and specifications.
- Exam all aspects of the aerosol extinguishing devices, for example, to inspect whether all the components and parts are firmly fixed or not, and please clean up the device to make sure it will not have much dust.
- After the aerosol units put in use, its expiration date is about 7 to 10 years, after the expiration date, please try to contact the supplier for replacement.
Aerosol fire protection system is have common features, normally described as follow:
- The third aerosol technology, and refill with strontium nitrate and potassium nitrate of aerosol chemical powder, strontium nitrate take proportion of about 50%, and potassium nitrate take about 10% to 20% proportion, china aerosol based compound is with advance technology and innovative.
- it is non-toxic, non corrosive, non conductive, not have any residue after suppression.
- It is Eco-friendly with zero value in Ozone-layer Depletion, Zero value in Global Warming Potential, Low value in Atmospheric Life Time.
- Space saving and compact, and simple construction, easy to install, easy to do system design, debugging and installation.
- Low in system maintenance after sale, not require years inspection.
Also wall mounted type of aerosol device have its special characteristics, there are listed as follow:
- Round cylinder shape like a indoor air conditioner.
- Could be install on the top ceiling of the room or on the wall above the protection objective, it is space saving for the project.
- IP 67 in water proof and dust proof performance.
Remark: hereby IP is IP code, which means what is the grade of dust protection and water protection.
