A

Standard Spray Head

81
Q

activated by a low level of heat and activate earlier because it requires less heat

A

Fast‐ response Sprinkler Head

82
Q

not typically intended to extinguish the fire, instead, it minimizes the heat buildup and the
production of carbon monoxide, which reduces the toxicity of the space while the occupants are exiting.

A

Residential Sprinkler Head

83
