Information About SIGA-OSD-IN
The SIGA-OSD-IN is part of the Edwards Signature Optica family of addressable detectors, designed for intelligent fire alarm systems. Unlike the standard SIGA-OSD, this model integrates an isolator, allowing it to automatically separate shorted sections of the loop while maintaining communication with other devices. It employs dual-angle, multi-wavelength optical sensing technology for accurate smoke identification, filtering out nuisance particles such as dust or steam. The detector supports multiple sensitivity settings, environmental compensation, and self-diagnostics, making it suitable for a wide range of commercial and industrial fire protection applications.
Key Features:
- Built-in Isolator: Provides automatic circuit isolation during short-circuit conditions.
- Advanced Optical Sensing: Dual wavelengths and multiple detection angles for accurate smoke detection.
- False Alarm Resistance: Intelligent algorithms reduce nuisance alarms from non-smoke particulates.
- Environmental Compensation: Adjusts sensitivity over time to maintain stable performance.
- Service Alerts: Two levels of dirty detector warnings for timely maintenance.
- Flexible Programming: Five sensitivity levels and twenty pre-alarm thresholds for customization.
- Loop Compatibility: Operates on Signature addressable circuits with up to 250 devices per loop.
- Automatic Device Mapping: Panel identifies and supervises device locations automatically.
- On-board Microprocessor: Enables distributed intelligence and faster decision-making.
- Diagnostic Functions: Self-testing with non-volatile memory for history and status retention.
- LED Status Indicators: Bicolor LEDs provide clear visual feedback for normal, alarm, and fault states.
The SIGA-OSD-IN delivers precise detection, built-in fault isolation, and system reliability for demanding fire safety applications.
