Knowing that most fire dampers are installed in areas of the building that are not easily accessible; installed in penetrations of fire rated walls and floors as required by the building code and access to the damper itself is normally through an improperly sized access door.
In those cases, would it be acceptable to perform a simple visual inspection to make sure the dampers are installed properly with no obstructions?
or is there an alternate testing and maintenance procedure for note easily accessible fire dampers?
Also, I've seen on a manufacturer website, a solution for testing problems. Wireless Damper Inspector system. Utilizing radio frequency, this remote control system cycles actuators of all life safety motorized dampers especially those that are installed in hard to reach or even inaccessible locations. According to the manufacturer, the Wireless Damper Inspector satisfies NFPA requirements for both initial and periodic testing of life safety dampers.
Could this testing procedure be acceptable according to NFPA 80?
Thanking you in advance for your help in this.
