Low Profile Smoke Detector MCT-426
Supervised Wireless PowerCode Smoke Detector

MCT-426 is a fully supervised wireless photoelectric smoke detector that is compatible with PowerMax(R) and other Visonic PowerCode(TM) wireless home security systems. Designed for a wide range of residential and commercial applications, the easily installed Visonic MCT-426 has a streamlined design and a longer battery life for easy and low-cost maintenance.

Achieving superior smoke detection sensitivity levels, the MCT-426 provides early warning of developing fire. When smoke is detected, MCT-426 issues both sound and transmitted alarms. 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.

Visonic MCT-426 low profile smoke 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.

Available in various frequency bands according to international standards, MCT-426 complies with strict international certifications for safety products in Europe.
