When to install the fire suppression system
Once you've selected a system and created a design, you're ready to install. Installation is done by authorized resellers, application engineers or trained end users. The time to install a fire suppression system depends on the complexity of the system and the equipment being protected. The installation of the pneumatic system usually takes about 4 hours, and the installation of the electrical system usually takes 16 hours. Time varies depending on the complexity of the installation, the components used, and the type of system being installed. Electrical systems have longer installation times due to electrical wiring and wiring, unlike pneumatic-only detection systems that do not require a power source or backup battery to activate. We will review the installation of a typical pneumatic fire suppression system.
