The Kidde GSA-IM2 Intelligent SLC Fault Isolator Module prevents a single wire-to-wire short from taking down an entire Class A Signaling Line Circuit. Install one between SLC segments and the module automatically isolates the fault - keeping the rest of the loop operational while you locate and fix the problem.
Built for the commercial installer
Rotary-addressed with dual rotary switches (TENS and ONES), the GSA-IM2 uses the same familiar addressing method as every other Kidde intelligent device on the loop. It draws just 175 µA in standby, mounts in a standard 4-inch square electrical box, and works with all KIR detectors and FX modules. Standard 12-18 AWG wiring - no twisted or shielded cable required.
Key features
- Automatic fault isolation: monitors SLC line voltage and opens the circuit when a wire-to-wire short is detected, isolating the fault between the two nearest isolator modules
- Protects Class A loop integrity: keeps the rest of the SLC operational during a wiring fault so other devices continue reporting to the FACP
- Precise ground fault detection: pinpoints the specific module location where the wiring problem occurred, cutting troubleshooting time
- Low SLC current draw: 175 µA standby, 200 µA activated - minimal impact on loop loading calculations
- Standard mounting: fits North American 4-inch square x 2-1/2 in. deep 2-gang box or standard 4 in. square box 1-1/2 in. deep
- Compatible with all KIR detectors and FX modules on Kidde intelligent fire alarm systems
System requirements
Requires a Kidde FX Series intelligent fire alarm control panel with an available SLC device address. Supports both 64-point (addresses 01-64) and 1000-point (addresses 01-127) panel configurations.
