The Kidde GSA-CT1 connects normally open dry contact initiating device circuits (IDCs) to the SLC loop of Kidde FX Series fire alarm control panels. Class A wiring provides redundant circuit paths so a single wire break won't take the zone offline - critical in high-rise, healthcare, and institutional occupancies where code requires Class A circuit operation.
Built for the commercial fire alarm installer
Rotary-switch addressing keeps commissioning simple - set the TENS and ONES dials, mount the module in a standard 4-inch electrical box, and register it from the panel. Four selectable personality codes (alarm latching, alarm delayed latching, non-latching monitor, and latching supervisory) let you match the module to the specific device type right at the module, without returning to panel programming. Ground fault detection pinpoints the exact module with a wiring problem, cutting troubleshooting time on large SLC loops.
Key features
- Class A (Style D) circuit operation for code-compliant redundant IDC monitoring
- Four selectable personality codes configurable at the module - alarm latching, alarm delayed latching, non-latching monitor, and latching supervisory
- Rotary-switch addressing from 01 to 127 - no programming tool needed
- Ground fault detection pinpoints the specific module with a wiring fault
- Bicolor LED status - flashing green (normal), flashing red (active) - visible during walkthroughs
- Mounts in standard 4-inch electrical boxes - 2-gang or single-gang, no special hardware
System requirements
Connects to the SLC (Signaling Line Circuit) of any Kidde FX Series intelligent fire alarm control panel. Supports 64 device addresses on a 64-point panel or up to 127 on a 1000-point panel. Wire with 12-18 AWG (16 and 18 AWG preferred).
