This morning at approximately 5:15 a.m., the Montvale Fire Department was alerted to numerous fire alarm activations at multiple buildings throughout town. It was quickly established that these alarms were all related to sprinkler systems and water pressure. We were then notified that Veolia had been doing work on the water tank and pumps. This activated water flow alarms in 19 sprinklered buildings nearly simultaneously. After each building was initially triaged by PD or FD, the FD assisted with resetting the alarms. This is an extremely rare and unusual occurrence. Chief M10, Deputy M11, Captains M12 & M13, Lieutenants M14 & M15, Rescue Pumper M1 and Engines M2 and M3 responded to a total of 19 fire alarm activations. All units were back in service by 7:30 AM.
