Which of the following is NOT a function of a sprinkler system?

A sprinkler system is primarily designed to automatically suppress flames and control the growth and spread of fire. Its main function is to discharge water in response to heat generated by a fire, effectively extinguishing or controlling the fire's intensity.

Controlling smoke spread is also a key aspect, as the water discharged can help mitigate the temperature and aid in preventing smoke from accumulating and spreading throughout a structure. Additionally, many sprinkler systems are connected to fire alarm systems, which automatically activate alarms when certain conditions are met (e.g., water flow or heat detection), thus alerting occupants and emergency services.

However, providing manual fire extinguishing options is not a direct function of a sprinkler system. Instead, manual fire extinguishing typically involves portable fire extinguishers that occupants or staff can use. The sprinkler system operates automatically without the need for manual intervention, which distinguishes its role from that of manual firefighting equipment.
