  • What's Included
  • The MCT-426 is a fully supervised wireless photoelectric smoke detector compatible with PowerMax and other Visonic PowerCode wireless systems. Achieving superior smoke detection sensitivity levels, the MCT-426 provides early warning of developing fire. When smoke is detected, it issues both sound and transmitted alarms and communicates it to connected systems. To ensure secure communication, transmissions use a PowerCode 24-bit ID command code, which is selected from 16 million possible combinations and is therefore unique and virtually impossible to accidentally reproduce. A smart anti-collision algorithm prevents signal jamming by simultaneous transmissions from multiple devices. Operates on one CR123A Lithium Battery for 5 years (typical).

    Battery doesn't last more than a year Review by SJC
    Battery doesn't last more than a year

    I have 4 of these and each has only lasted 1 year on the battery...not 5-8 years!
    I even replaced them with better batteries (energizer and duracel) different.
