Information About SD-PH
The SD-PH is part of Edwards Signaling duct detection accessory solutions engineered to protect SuperDuct smoke detectors in ventilation systems. It is constructed as a rugged protective enclosure suitable for installation in HVAC ductwork exposed to moisture, temperature variation, and continuous airflow. The unit supports multiple operating voltage configurations, including 24 VAC, 24 VDC, 120 VAC, and 230 VAC, making it compatible with a wide range of fire alarm and building control systems. It is designed for use in air velocities from 100 ft/min to 4,000 ft/min, ensuring stable detector operation in both low and high airflow duct environments. RJ-45 wiring support simplifies integration with modern fire alarm communication and control networks.
Key Features:
- Duct Detector Protection: Shields compatible smoke detectors from dust, humidity, and airflow stress
- High Humidity Suitability: Designed for reliable operation in moisture-prone HVAC environments
- Wide Air Velocity Range: Supports stable performance from 100 to 4,000 ft/min duct airflow
- Multi-Voltage Compatibility: Accepts 24 VAC, 24 VDC, 120 VAC, and 230 VAC systems
- HVAC Integration Design: Optimized for SuperDuct detector installation in air handling units
- Extended Temperature Range: Operates reliably from -4°F to 158°F
- RJ-45 Connectivity: Simplifies wiring and system integration in fire alarm networks
The SD-PH delivers the reliability and precision required for duct smoke detection protection in HVAC and fire safety systems.
