Edwards SIGA-TCDR

The Edwards EST SIGA-TCDR is an intelligent addressable temporal pattern generator module for EST QuickConnect fire alarm systems. It provides separate audible alarm signals for fire and carbon monoxide detection by generating NFPA 72 temporal patterns (TC3 or TC4) from a single address. The module pairs with compatible AB4GT or AB4G-LF sounder bases to deliver code-compliant alarm notification.

Key Features

• Temporal pattern generation for fire and CO distinction on compatible sounder bases
• Two addressable channels for separate Fire (TC3) and CO (TC4) pattern control
• Supports AB4GT (CO-compatible) and AB4G-LF (520 Hz low-frequency) sounder bases
• SYNC signal synchronization for multi-device coordination
• Uses two SLC addresses (one per channel) on the signaling line circuit
• Powered by connected sounder base riser system
