What is the maximum throw for a horizontal sidewall sprinkler? Just looking for a typical extended coverage sprinkler, not a dry-type.

Light hazard/residential sleeping unit is what I'm looking to protect. Thanks David!

Depends on the listing of the sprinkler head, and how much water pressure you have available.

Tyco TY-FRB 5.6K EC head can cover 16'x22'. The 8.0K model can cover 16'x24'.

Viking VK460 residential heads are listed for 14'x26' - though you'll need calcs to prove you have 46 GPM at 63 PSI at the most remote head, which can be a deal breaker.

If you need longer widths (instead of distances), it's worth looking at "corridor" sprinklers like the VK638.

For a residential lodging, you can use a conventional sidewall or a residnetial sidewall sprinkler.

For the actual protection area, look at their datasheets. These data sheets will provide information on the gpm and pressure it will require. These numbers are provided for each protection area.

Examples of companies: Viking, Reliable, Globe, Tyco.
