GSA-CC1/MCC1 Single Input Signal Modules and GSA-CC2/ MCC2 Dual Input Signal Modules are part of Kidde's Signature Series system. They are intelligent analog addressable devices 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-CC1/MCC1 and GSA-CC2/ MCC2 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-CC1 and GSA-CC2 mount to standard North American two-gang electrical boxes, making them ideal for locations where only one module is required. Separate I/O and data loop connections are made to each module.

The GSA-MCC1 and GSA-MCC2 are part of the UIO family of plug-in Signature Series modules. They function identically to the GSA-CC1 and GSA-CC2, but take advantage of the modular flexibility and easy installation that characterize all UIO modules. Two- and six-module UIO motherboards are available. These can accommodate individual risers for each on-board module, or risers that are shared by any combination of its UIO modules. All wiring connections are made to terminal blocks on the motherboard. UIO assemblies may be mounted in Kidde enclosures.

Standard Features

Single and Dual input (riser) select
Use for connecting supervised 24 Vdc Audible/Visible signal circuits, or 25 and 70 VRMS Audio Evacuation and Telephone circuits to their power inputs.

Ring-tone generator
When configured for telephone circuits, the GSA-CC1 generates its own ring-tone signal eliminating the need for a separate ring-tone circuit.

Plug-in (UIO) or standard 2-gang mount
UIO versions allow quick installation where multiple modules are required. The 2-gang mount version is ideal for remote locations that require a single module.

Automatic device mapping
Signature modules transmit information to the loop controller regarding their circuit locations with respect to other Signature devices on the wire loop.

Electronic addressing
Programmable addresses are downloaded from the loop controller, a PC, or the SIGA-PRO Signature Program/Service Tool; there are no switches or dials to set.

Intelligent device with microprocessor
All decisions are made at the module to allow lower communication speed with substantially improved control panel response time and less sensitivity to line noise and loop wiring properties; twisted or shielded wire is not required.

Ground fault detection by address
Detects ground faults right down to the device level.

Installation

The GSA-CC1 and GSA-CC2: mount to 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.

GSA-MCC1 and GSA-MCC2: mount the UIO motherboard inside a suitable Kidde enclosure with screws and washers provided. Plug the GSA-MCC1 or GSA-MCC2 into any available position on the motherboard and secure the module to the motherboard with the captive screws. Wiring connections are made to the terminals on the motherboard (see wiring diagram). UIO motherboard terminals are suited for #12 to #18 AWG (2.5 mm2 to 0.75 mm2 ) wire size.
