Introduction | The Problems With Conventional Doors  

Tested and Approved Installation | Significant Advantages to Building Owners

 

Installation is Easy and Economical

• Saves the cost of replacing an existing non-functional fire door.

• No ladders, tools or door technicians required to drop test & reset door.

• Controlled rate of descent during self-closing mode (6" per second)

• Automatically resets itself after being drop tested.

• Multiple fire doors may be drop tested and reset simultaneously.

• Operational safety edge during the self closing mode.

 

 

The Retrofit Option eliminates the need for through-the-wall sash chains to connect multiple fire doors together. This is particularly significant on Maximum Fire Loss (MFL) walls where two fire doors are installed back to back (same opening). In this case it is difficult to make the two doors drop test simultaneously when only one fusible link is cut.

 

The fire door operator solves this problem. If two or more fire door operators are installed on an MFL wall, they can be connected in series through low voltage wiring. If one fusible link is cut on one fire door operator, that in turn would cut power to all of the operators tied in series, causing all of the doors to self-close.

 

This means more reliability. If a fusible link is not functional due to dust, paint, improper installation, etc., and a single fusible link elsewhere is activated, it will cause all of the fire doors which are tied in series to close.

 

Low Cost / Easy Testing & Resetting

IMPORTANT! For Safety, Trip-Test Fire Doors Frequently!
McKeon recommends fire doors be trip tested monthly (or even weekly) to identify maintenance problems. With the Auto-Set, they can all be drop tested simultaneously & just cut the power to the operators!
