KD-GSA-CT2

The GSA-CT2 adds two independently monitored input circuits to any Kidde FX Series intelligent fire alarm panel, letting installers bring normally open contact devices - waterflow switches, pull stations, tamper switches, supervisory contacts - onto the SLC without running a separate module for each zone.

Built for the commercial fire installer

Class B circuit operation with rotary addressing keeps setup fast and familiar. Two rotary switches on the front set the device address, no laptop required. The module uses two consecutive SLC addresses (the second auto-assigns one higher than the set value), so plan your address map accordingly. Four selectable personality codes per circuit let you configure each input independently for alarm latching, alarm delayed latching, non-latching monitor, or latching supervisory operation - either from the on-board slide switch or through panel programming.

Key features

  • Two independent input circuits on a single module - reduces device count and wiring runs on multi-zone jobs
  • Ground fault detection pinpoints the specific module where a wiring fault has occurred, cutting troubleshooting time
  • Four personality codes per circuit: alarm latching, alarm delayed latching, non-latching monitor, or latching supervisory
  • Rotary switch addressing - no programming tool needed at initial install
  • Distributed intelligence - on-board microprocessor handles command decisions locally, keeping panel response times fast
  • Standard wiring compatible - no twisted or shielded cable required, reuse existing runs when upgrading from conventional to intelligent

System requirements

How many SLC addresses does this module use?
Two consecutive addresses. The second address auto-assigns one number higher than the value set on the rotary switches. Plan your address map to leave room for both.
Does this support Class A circuit operation?
No. The GSA-CT2 (FX-IDC2B) is Class B only. For Class A single-input operation, see the GSA-CT1A (FX-IDC1A).
What electrical box does this mount in?
Standard North American 4-inch square box. Either a 2-1/2 in. deep 2-gang box or a standard 1-1/2 in. deep box. Includes a wall plate cover.
Can I configure each input circuit independently?
Yes. Four personality codes are available on each circuit: alarm latching, alarm delayed latching, non-latching monitor, and latching supervisory. Set via the on-board slide switch or through panel programming.
Does this require twisted or shielded cable?
No. Kidde intelligent modules work with standard 12-18 AWG wiring. When upgrading from a conventional panel to FX Series, you can typically reuse existing wire runs.
What end-of-line resistor does this module use?
47 kĪ© (Kidde P/N: EOL-47). One required per input circuit.
