Freeze averted at Carlisle School
On a day with degrees hovering around 10 degrees a freeze prevention alarm sounded at Carlisle School. Building and Grounds Supervisor David Flannery received a call on February 7 that the alarm for the Spalding Building was activated. “The alarm sensors report to Lexington Alarm Systems,” explained Flannery in an email. “The space sensor reported a low temperature.” He said Custodian Daniel Flannery was at the school working on a special detail clean-up. He was sent to the Spalding Building, Flannery explained, and found that the large blower had shut down. “After checking and lubricating a sticky bearing he was able to restart the blower,” said Flannery.
Flannery had applied and received a $4,492 grant last year from the town’s insurance company, MIIA, to purchase the freeze prevention systems, which were installed in all buildings. “Temperature sensors were installed in two areas of each building in addition to sensors to report the failure of the burners to start,” explained Flannery. “So a freeze-up was prevented and the system paid for itself.” ∆
