It is important to understand the features and performance of the various fire safety equipment systems in order to properly address the objectives.

Sprinkler Example

If the objective is to have early warning in a building, sprinklers on their own may not be adequate. Sprinklers are generally heat activated and can only protect the area where they are installed. Smoke can migrate from one area to another, and a sprinkler head installed outside the compartment of fire origin may not activate. Unless the sprinkler system is designed to put out a fire, smoke can still migrate through windows or under doors into rooms making it unsafe for the occupants. In this case, smoke detectors/alarms may be considered as better tools to alert the occupants, or a sprinkler system connected to a fire alarm will be more appropriate for the situation. More information on Sprinkler Upgrades.

Fire Alarm Example

Another example is on orders written to improve the audibility of a fire alarm system. The objective to provide early warning may not be achieved if the residence have mobility problems (hence cannot vacate the building on their own even if alarm is sounded) or have health issues with loud sounds. Using visual aids in addition to providing off site monitoring for an earlier response time may be more beneficial. The Local Assistant needs to recognize the site specific factors to seek the best overall solution.
