Silent Knight SD505-PHOTO Smoke Detector
The Silent Knight SD505-PHOTO Smoke Detector offers reliable fire detection for a wide range of applications. Utilizing advanced photoelectric sensing technology, this device responds quickly to the presence of smoke from slow-burning, smoldering fires. Its intelligent design ensures precise performance while minimizing false alarms.
Key Features
Photoelectric Detection Technology
This smoke detector uses a sophisticated photoelectric sensing chamber that accurately detects visible particles produced during early fire stages. As a result, it offers faster and more dependable detection in various environments.
Addressable Capability
Engineered for addressable fire alarm systems, the SD505-PHOTO assigns a unique address to each unit. This feature enables the control panel to pinpoint the exact location of an alarm or fault, which greatly improves response time during emergencies.
LED Status Indicator
A bright LED provides visual feedback by indicating device status—green for normal operation, red for alarm, and amber for trouble. Therefore, technicians can quickly assess the unit’s condition during inspections.
