Visonic Ltd. released the MCT-427 wireless smoke and heat detector, which is compatible with Visonic’s PowerMax® family. With a streamlined design that fits any residential or commercial application, MCT-427 features a significantly extended battery life of up to eight years. The MCT-427 offers superior fire detection sensitivity, including the ability to sense rapid temperature changes and detect smoke. It monitors temperature changes and activates an alarm when the temperature reaches 50 deg. C (122 deg. F) and starts increasing rapidly. The MCT-427 is a fully supervised wireless detector, and issues alerts regarding low batteries, a dirty sensor that needs to be cleaned, and other malfunctions. It is part of Visonic’s Home Safety Series, which also includes CO, natural gas, temperature and water leak detectors.
