Overview

Provide dependable, low-maintenance fire protection for your facility with the System Sensor 4WT-B photoelectric i3 series combination detector. Engineered for commercial security and monitoring, this 4-wire detector combines a photoelectric smoke chamber with a 135°F fixed thermal sensor to quickly detect smoldering or fast-rising fires while reducing nuisance alarms. The plug-in i3 design and large wire entry port speed installations and service, and Stop‑Drop 'N Lock mounting lets technicians swap heads without rewiring. With built-in drift compensation, smoothing algorithms, and remote maintenance signaling, the 4WT-B minimizes false alarms and simplifies routine sensitivity testing—cutting maintenance time for security and facilities teams. The unit supports 24V DC input, includes a loud 85 dB sounder and a Form C relay for easy integration with fire panels, access control, and surveillance systems. Backed by a 3-year limited warranty, the System Sensor 4WT-B is a practical choice for buildings that require reliable detection and streamlined monitoring.
