The quick release for security bars system automatically unlocks the security bars fitted on the exterior of a building in response to a signal from a fire detection device. On any window or other opening fitted with hinged security bars, one or more quick release latching mechanisms are attached to the side of the bars opposite the hinges. The quick release latching mechanism has an electric solenoid wherein the plunger of the solenoid is fitted with a male portion that engages with a fixed female portion. When a fire detection device, such as a heat detector, smoke detector, or gas sensor, triggers an alarm, power to the solenoid is interrupted and the plunger of the solenoid extends and disengages the male portion from the female portion and therefore disengages the security bars.
