Fire Sprinkler Monitoring

Fire Sprinkler Systems are intended to suppress or extinguish fires. Most municipalities and insurance companies require that fire sprinkler systems are monitored by a U.L. approved monitoring center such as ESI. We install the most technologically advanced fire sprinkler systems available complete with Flow Switches that can detect when there is water movement or a sudden drop in pressure which activates an alarm notification. Our Tamper Switches detect partial or fully closed sprinkler valves and also activates an alarm notification.

In addition to the notifying the fire department in the event of a sprinkler activation due to a fire, ESI’s monitoring of these sprinkler systems also provide notification in the event of the following issues:

Fire Pump Running - Most fire pumps when activated, will continue to run until manually shut down. If their activation is inadvertent or unknown, they can run until they destroy themselves.

Water is flowing due to a failure or break in the sprinkler system. This is extremely important during times when the building is unoccupied.

Low air in a "dry pipe" system. To prevent low temperature damage to the sprinkler systems pipes or other damage. Some systems have the water pipes filled with air until a fire is detected. If the air pressure part fails, the system can become "flooded" and cause damage.

Notifications in the event the supply water valves are turned off. The fire sprinkler system cannot function without water.
