New Lenox, IL – Residents across New Lenox are being urged to remain alert after the New Lenox Fire District issued a public safety reminder warning that rapid temperature fluctuations can trigger fire alarms—even when there is no smoke or fire present.
According to the New Lenox Fire District, condensation can form inside homes as temperatures rise and fall, particularly in attics, basements, and near alarm sensors. That moisture buildup may cause smoke or fire alarms to activate unexpectedly, leading to emergency responses that appear to be false alarms but must still be treated seriously.
Fire officials stressed that any alarm activation should always be handled as a real emergency. Residents are advised to call 911 immediately and never assume an alarm was triggered by a malfunction or weather-related issue.
In addition to alarm concerns, the department is reminding homeowners that sudden cold snaps increase the risk of frozen pipes, which can burst and cause extensive water damage. This risk is higher in crawl spaces, garages, exterior walls, and unheated areas of homes.
To reduce the likelihood of issues during extreme cold, fire officials recommend keeping indoor temperatures steady—even overnight—properly maintaining smoke and fire alarms, and improving ventilation in bathrooms, kitchens, and basements. Insulating exposed pipes and allowing faucets to drip slightly during extreme cold can also help prevent freezing.
Residents are also encouraged to know the location of their main water shut-off valve in case a pipe bursts.
The advisory applies to New Lenox in Will County and surrounding southwest suburban areas of the Chicago metro, where winter temperature swings are common.
Fire officials say staying proactive during cold weather not only protects individual homes but helps reduce emergency risks across the community.
