Edwards SIGA-SD Intelligent Duct Smoke Detector (NEW)
Edwards/EST SIGA-SD Intelligent Smoke Detector — Product Overview
The SIGA-SD is an intelligent photoelectric smoke detector designed for use with Edwards EST Signature Series control panels. Using advanced optical sensing technology, it delivers early warning of developing fires by detecting smoke particles in the air.
Key Features:
-
Intelligent Self-Diagnostics: The detector continuously monitors its own sensitivity and operational status, automatically adjusting for environmental conditions to minimize false alarms.
-
Drift Compensation: Automatically compensates for dust accumulation and aging, maintaining consistent performance over time without frequent recalibration.
-
Dual LED Status Indicators: Provides 360° visibility for normal operation, trouble, or alarm conditions.
-
Plug-In Mounting: Simplified installation using a twist-lock base; compatible with various Signature Series detector bases.
-
Electronic Addressing: Each detector has a unique, programmable address, ensuring precise identification and reporting to the control panel.
-
Optional Heat Detection: With some models, heat sensing is available to supplement smoke detection in challenging environments.
-
Field-Testable: Easily testable using a magnet without special tools.
-
