Overview

Built for commercial fire detection and security monitoring, the System Sensor 2W-B Photoelectric i3 smoke detector streamlines installation, reduces false alarms and simplifies ongoing maintenance. The i3 plug-in design lets technicians pre-wire bases and secure the head with the Stop-Drop N Lock attachment, accelerating installs on 2-wire, 24V systems. The photoelectric sensing chamber—backed by drift compensation and smoothing algorithms—minimizes nuisance alarms from dust or steam, improving reliability for surveillance and life-safety systems.

Serviceability is a priority: wide-angle red/green LEDs provide instant condition checks, an onboard test switch supports quick functional tests, and EZ Walk loop testing (with i3-capable panels or the 2W-MOD2 module) verifies loop wiring. Remote maintenance signaling and simplified sensitivity readout make compliance and monitoring easier for building managers and security integrators. UL 268 listing and multiple mounting options ensure code-compliant deployment in offices, schools, healthcare and retail environments.
