Kidde | Analog Addressable Dual Input IDC Monitor Module, Class A-B, SLC Loop | GSA-MCC2

The Kidde GSA-MCC2 connects two initiating device circuits to a Kidde intelligent fire alarm control panel over a single SLC loop - no dedicated wire runs back to the panel for each zone. Two rotary-addressed IDC inputs fit into one compact module, cutting install time on mid-size commercial jobs where zone count stacks up fast.

Built for the commercial fire alarm installer

Class A (Style Z) and Class B (Style Y) circuit operation covers both riser and branch wiring topologies. Each module consumes two consecutive SLC addresses starting with an even number, and the panel auto-maps both zones on enrollment. The module ships configured as alarm-latching from factory - supervisory and monitor types are field-selectable at the panel.

Key features

• Two IDC zones per module: cuts device count and SLC address consumption on multi-zone jobs
• Class A and Class B wiring support: matches the riser topology already on the job, no adapter modules needed
• SLC loop powered: no separate power supply required at the module location
• Rotary address switches: set addresses in the field without a laptop or programming tool
• Standard electrical box mounting: fits 4" square x 2-1/2" deep 2-gang or standard 4" square 1-1/2" deep boxes
• Compatible with Kidde FX Series panels: works with both 64-point and 1000-point intelligent fire alarm control panels

System requirements

Requires a Kidde FX Series intelligent fire alarm control panel with available SLC capacity. Two consecutive addresses (starting even) per module. 47 kΩ EOL resistor (P/N: EOL-47) required at the end of each IDC zone. Preferred wire sizes: 16 and 18 AWG.
