MCT 427 is a fully supervised wireless heat and photoelectric smoke detector that is compatible with the PowerMax home security systems and other Visonic PowerCode™ wireless receivers. With a streamlined design that fits any residential or commercial application. This heat smoke alarm has a significantly longer battery life of up to eight years, enabling easy and low-cost maintenance. By sensing rapid temperature changes in areas where they may occur, such as kitchens or attics, the 427 activates an alarm when the temperature reaches 60°C (140°F) and starts increasing rapidly. The detector also achieves superior smoke detection sensitivity levels by providing early warning of a developing fire. When smoke is detected, MCT 427 issues a transmission with a loud-sounding alarm, making it impossible to miss any event. The detector also transmits supervisory reports, including battery condition, to the wireless control panel or receiver at regular intervals – ensuring system integrity and functionality at all times. The MCT 427 is very easy to install with a simple wall or ceiling mount bracket.
