Kidde GSA-CC2 Dual Input (Riser) Module

Key Features:

  • Single and Dual input (riser) select
  • Connects supervised 24 Vdc Audible/Visible signal circuits to their power inputs.
  • Connects 25 and 70 VRMS Audio Evacuation and Telephone circuits to their power inputs
  • Plug-in (UIO) or standard 2-gang mount for quick installation of multiple modules
  • The 2-gang mount is ideal for remote locations with a single module
  • Transmits information to the controller regarding their locations with respect to other devices on the loop
  • Programmable addresses are downloaded from the loop con­troller, a PC, or the SIGA-PRO Signature Program/Service Tool
  • All decisions are made at the module to for lower com­munication speed with improved control panel response time
  • Less sensitive to line noise and loop wiring properties
  • Detects ground faults right down to the device level.

Kidde’s GSA-CC2 Dual Input Riser Module is part of Kidde’s Signature Series system. It is an intelligent analog addressable device used for connecting, upon command from the loop controller, supervised Class B signal or telephone circuits to their respective power inputs. The power inputs may be polarized 24 Vdc to oper­ate audible and visible signal appliances or 25 and 70 VRMS to operate audio evacuation speakers and firefighter’s telephones.

The actual operation of the GSA-CC2 device is determined by the “personality code” selected by the installer. It is downloaded to the module from the Signature loop controller during system configuration.


The GSA-CC2 Dual Input Riser mounts to standard North Ameri­can 2-1/2 inch (64 mm) deep two-gang boxes and 1-1/2 inch (38 mm) deep 4-inch square boxes with two-gang covers and GSA-MP mounting plates. The terminals are suited for #12 to #18 AWG (2.5 mm2 to 0.75 mm2) wire size. The device is ideal for locations where only one module is required. Separate I/O and data loop connections are made to each module.

Electronic Addressing

The loop controller electronically ad­dresses each module saving valuable time during system com­missioning. Setting complicated switches or dials is not required. Each GSA-CC2 module has its own unique serial number stored in its on-board memory. The loop controller identifies each device on the loop and assigns a “soft” address to each serial number. If desired, the modules can be addressed using the SIGA-PRO Signature Program/Service Tool.


The operation of Kidde’s GSA-CC2/MCC2 Dual Input Riser is determined by its sub-type code or “Personality Code”. The code is selected by the installer depending upon the desired ap­plication and is downloaded from the loop controller. Personality Code 7 is assigned to the GSA-CC2 and automatically applies to both circuits (A and B). It is factory assigned and no user configuration is required.

Personality Code 7: SIGNAL POWER or AUDIO EVACUA­TION (DUAL RISER). Con­figures the module for use as a two circuit Class B Audible/Visible Signal power (24 Vdc polarized) or Audio Evacuation (25 or 70 VRMS) power selector. The single output circuit is monitored for open or shorted wiring. If a short exists, the control panel inhibits the activation of the audible/visible signal circuit to prevent con­nection to the power circuit.


The GSA-CC2 Dual Input Riser module is compatible only with Kidde’s Signature Loop Controller.

Testing & Maintenance

The GSA-CC2 module’s automatic self-diagnosis identifies when it is defec­tive and causes a trouble message. The user-friendly maintenance program shows the current state of each module and other perti­nent messages. Single modules may be turned off (de-activated) temporarily, from the control panel.

Typical Wiring (GSA-CC2)

Modules will accept #18 AWG (0.75mm2), #16 (1.0mm2), #14 AWG (1.50mm2) and #12 AWG (2.5mm2) wire sizes.

Note: Sizes #16 AWG (1.0mm2) and #18 AWG (0.75mm2) are preferred for ease of installation.
