Fog machines create a visible vapor commonly used for atmospheric effects in entertainment, photography, and industrial applications. These devices typically use either water-based fluids or glycol-based fluids to produce this effect. While the intent is visual, the resulting vapor can sometimes trigger devices designed to detect smoke. Water-based fog is less likely to cause an issue than denser glycol-based fog which can linger in the air and potentially scatter light particles similarly to smoke.
Understanding the potential interaction between vapor-producing devices and fire safety systems is crucial for both event organizers and homeowners. Unnecessary alarm activations can disrupt events, cause inconvenience, and potentially lead to costly false alarm fines. Furthermore, repeated false alarms can desensitize individuals to the sound of the alarm, increasing the risk of ignoring a genuine fire emergency. Historically, fire detection systems have relied on ionization and photoelectric sensors. While these technologies have saved countless lives, they are not always sophisticated enough to differentiate between theatrical fog and actual smoke.
