For a sprinkler system with less than 300 sprinklers, how many spare stock sprinklers are required?

In sprinkler system design and installation, maintaining an adequate supply of spare sprinklers is crucial for efficient maintenance and repair. When the system has fewer than 300 sprinklers installed, the code typically recommends having at least 6 spare sprinklers on hand. This ensures that in case of accidental damage, maintenance, or replacement of malfunctioning units, there are sufficient spare sprinklers readily available to avoid prolonged downtime.

Having fewer than 6 spare sprinklers could lead to delays in repairs and potentially leave areas unprotected if a sprinkler needs to be replaced immediately. The requirement for 6 is established to promote safety and ensure that fire protection is not compromised. This recommendation is beneficial in maintaining the integrity of the fire protection system, which is a regulatory expectation in many standards governing sprinkler system installations.
