Information About SK-DUCT-W
The SK-DUCT-W is a photoelectric duct smoke detector engineered for installation in HVAC ductwork to detect smoke transported by air movement. It is designed to operate across a wide air velocity range from 100 to 4000 feet per minute, making it suitable for various airflow conditions. The unit supports a remote test function, allowing maintenance personnel to perform testing without direct access to the detector housing. Built for compatibility with Silent Knight addressable modules, it operates within a regulated 15–32 VDC range and meets environmental requirements for commercial fire alarm applications.
Key Features:
- Photoelectric Smoke Detection: Uses optical sensing technology for early smoke identification.
- Low-Flow Capability: Operates in air velocities from 100 to 4000 ft./min.
- Clear Cover Design: Allows visual inspection of chamber and status indicators.
- Remote Test Function: Supports remote functional testing for maintenance efficiency.
- Wide Voltage Range: Operates from 15 to 32 VDC.
- Low Standby Current: 200 µA @ 24 VDC with LED blink enabled.
- LED Alarm Indication: Maximum alarm current of 6.2 mA @ 24 VDC.
- Flexible Footprint Options: Available in rectangular and square mounting configurations.
The SK-DUCT-W delivers the reliability and precision required for HVAC duct smoke detection in commercial fire alarm systems.
