SAE SSU-SL-2000-P Duct Smoke Detectors, Photoelectric Detection

Protect building occupants and assets with reliable, early duct smoke detection. The Space Age Electronics SSU-SL-2000-P photoelectric duct smoke detector is engineered to detect smoke in HVAC supply and return air streams—stopping smoke spread and enabling automatic HVAC shutdowns to limit damage and downtime. Using photoelectric sensing optimized for low-flow conditions (100–4000 ft/min), the SL-2000 delivers fast, dependable detection without nuisance alarms common in duct applications.

Designed for commercial and industrial security and fire monitoring, the SL-2000 supports multiple power inputs (24VDC/24VAC and 120–230VAC), provides generous wiring space for easy integration, and can interconnect up to 30 units for centralized surveillance and alarm coordination. Service-friendly features — including patent-pending no-tools sample tube removal and a Test Port Valve for aerosol testing — cut maintenance time and lower lifecycle costs. UL-listed and code-compliant, it’s ideal for data centers, hospitals, office buildings, and any facility requiring HVAC-linked fire protection.
