Quick Response sprinklers in a building are due for testing. The building contains 800 concealed sprinklers, 300 upright sprinklers, and 200 pendant sprinklers, how many sprinklers need to be sent off for testing?

To determine how many Quick Response sprinklers need to be sent off for testing, it's important to consider the requirements and standards set for testing sprinklers in a system. Generally, the National Fire Protection Association (NFPA) provides guidelines for the frequency and quantity of sprinklers that should be tested.

In this situation, Quick Response sprinklers are typically tested by sampling a certain percentage of the total number of installed sprinklers. According to NFPA guidelines, the minimum number of sprinklers to be sampled for testing should ensure a representative assessment of the entire system.

Assuming that only a small subset of a large number of sprinklers needs to be tested, 16 would follow the typical sampling procedure for a larger number of total sprinklers in the building, which includes 800 concealed, 300 upright, and 200 pendant sprinklers, adding up to a total of 1300 sprinklers.

Testing 16 sprinklers from this total is in line with practices that advocate for a mixture of types and locations to assess the performance of all categories of sprinklers in the system. Such a sample size would be viable to ensure reliability without the need for exhaustive testing of each individual sprinkler installed. This approach effectively balances thoroughness and practicality in maintaining the fire protection
