Crow FW2-SMK Wireless Smoke & Heat Detector IP41 / IK02 Photoelectric Smoke

The Crow FW2-SMK is a two-way wireless photoelectric smoke and heat detector designed for professional security and life-safety installations where reliable early fire detection is essential. Employing photoelectric sensing technology, it is engineered to detect the presence of smoke with consistent sensitivity over time, making it well suited for commercial, light industrial, and residential environments that demand dependable performance without the maintenance burden of wired infrastructure. A key operational advantage of the FW2-SMK is its automatic drift compensation capability, which continuously adjusts for gradual environmental changes — such as dust accumulation or humidity variation — that would otherwise cause sensitivity to degrade or false alarms to increase. When the compensation mechanism reaches the boundary of its adjustment range, the detector transitions into a trouble state, providing installers and monitoring operators with a transparent, actionable alert rather than silent failure. As a two-way wireless device, the FW2-SMK participates in bidirectional communication with its host system, enabling supervisory polling, status confirmation, and remote diagnostics that elevate overall system integrity well beyond what one-way wireless devices can offer. Intended for integration into professional alarm and intrusion systems, it delivers the kind of self-monitoring intelligence and wireless flexibility that modern installers require when running new cable is impractical or cost-prohibitive.

Key features & benefits

• Photoelectric Smoke Detection — Utilizes photoelectric sensing technology to detect smoke particles associated with a wide range of fire types, providing reliable early warning suited to diverse installation environments.
• Automatic Drift Compensation — Continuously self-calibrates to account for long-term environmental changes such as dust and humidity, maintaining consistent smoke sensitivity throughout the detector's operational life without manual intervention.
• Transparent Trouble Reporting — When drift compensation reaches its adjustment limit, the detector enters a clearly defined trouble state, giving installers and central station operators an unambiguous signal to schedule inspection or maintenance.
• Two-Way Wireless Communication — Bidirectional radio communication enables the host control panel to actively poll the device and receive confirmed status responses, supporting superior supervisory oversight compared to one-way wireless alternatives.
• Low-Current Design — Engineered for efficient power consumption, extending battery service intervals and reducing the frequency of site visits for routine maintenance — a practical benefit in hard-to-access or high-density installations.
• Professional-Grade Reliability — Built to the standards expected of professional security integrators and alarm operators, the FW2-SMK is appropriate for commercial, light industrial, and high-end residential deployments where system integrity is non-negotiable.
• Wireless Installation Flexibility — Eliminates the need for dedicated detector cabling, making the FW2-SMK an effective solution for retrofit projects, heritage buildings, or any environment where cable routing is impractical or disruptive.
