Kidde | Addressable TC3/TC4 Temporal Pattern Generator for Intelligent Sounder Bases | GSA-T3T4

The GSA-T3T4 generates synchronized fire and CO temporal sound patterns through Kidde Intelligent sounder bases on the SLC loop. One addressable module handles both TC3 (fire, NFPA 72) and TC4 (CO, NFPA 720) signaling - no separate pattern drivers or dedicated NAC circuits needed at each base location.

Built for the commercial installer

The module takes two addresses on the Signature Series SLC and responds to synchronization and channel commands from the panel. Channel 1 drives TC3 fire temporal, Channel 2 drives TC4 CO temporal. It works with both the GSA-SBT standard sounder base and the SIGA-AB4G-LF low-frequency sounder base (520 Hz for sleeping areas per NFPA 72). Indoor rated, 32-120F operating range, UL/ULC/CSFM listed.

Key features

• Dual-channel fire and CO signaling from a single addressable SLC module
• TC3 and TC4 temporal patterns per NFPA 72 and NFPA 720
• Panel-synchronized output keeps all connected sounder bases on the same cadence
• Compatible with GSA-SBT and SIGA-AB4G-LF sounder bases for standard and low-frequency applications
• Two SLC addresses per module - one per channel, enrolled like any other Signature Series device
• UL, ULC, and CSFM listed for fire protective signaling

System requirements

Requires a Kidde Signature Series FACP with available SLC capacity and 24 VDC power-limited regulated supply. Each GSA-T3T4 consumes two SLC addresses. Compatible sounder bases (GSA-SBT or SIGA-AB4G-LF) mount Signature Series intelligent detectors directly above the base.
