MCC1S Synchronization Output UIO (Plug-in) Module

Manufacture: kidde
Product code: MCC1S

✅ Synchronization Output Modules is intelligent analog addressable devices that form part of Kidde’s Signature line of products ⭐
✅ The actual operation of the GSA-CC1S is determined by the “personality code” selected by the installer, which is downloaded to the module the Signature loop controller during system configuration. Depending on their assigned personality, Synchronization Output Modules may be used as a signal power riser selector to provide synchronization of fire alarm signals across multiple zones, or for connecting, upon command 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.

Product information

Standard Features

• Provides UL 1971-compliant auto-sync output for visual signals Use for connecting a supervised output circuit to a supervised 24 Vdc riser input and synchronizing multiple notification appliance circuits.

• Functions as an audible signal riser selector Use as a synch module or for connecting supervised 24 Vdc Audible/Visible signal circuits, or 25 and 70 VRMS Audio Evacuation and Telephone circuits to their power inputs.

• Built-in ring-tone generator When configured for telephone circuits, the GSA-CC1S generates its own ring-tone signal, eliminating the need for a separate ring-tone circuit.

• 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 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.


The GSA-MCC1S is part of the UIO family of plug-in Signature Series modules. It functions identically to the GSA-CC1S, but takes 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.


GSA-MCC1S: mount the UIOxR motherboard inside a suitable Kidde enclosure with screws and washers provided. Plug the module 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). UIOxR motherboard terminals are suited for #12 to #18 AWG (2.5 mm2 to 0.75 mm2 ) wire size.
