Module - Universal Class A/B (MAB)

The GSA-UM and GSA-MAB are Universal Class A/B Modules. They are intelligent analog Addressable devices that are part of the Signature Series system. The actual function of the module is determined by the “personality code” selected by the installer. This is downloaded to the module from the Signature loop controller during system configuration. The GSA-UM and GSA-MAB gather analog information from the slave devices connected to them and convert this into digital signals. Each module’s on-board microprocessor measures and analyzes the signal and decides whether or not to input an alarm.

The GSA-UM is installed to a standard North American 2-gang electrical box, making it ideal for locations where only one module is required.  Separate I/O and data loop connections are made to each module. The GSA-UM may be used to connect any one of the following:

• Two Class B or one Class A Initiating Device Circuits
• One Class A or B Notifi cation Appliance Circuit
• One Class A or B Circuit for 2-wire Smoke Detectors
• One Form “C” (NO/NC) Dry Output Contact Relay

The GSA-MAB is part of the UIO family of plug-in Signature Series modules. It takes advantage of the modular fl exibility and easy installation that characterizes all UIO modules. Two- and six-module UIO motherboards are available. These can accommodate individual risers for each on-board module, or shared risers in any combination with their UIO modules. All wiring connections are made to terminal blocks on the motherboard. UIO assemblies may be mounted in the multi-function fire cabinet or equipment cabinets. The GSA-MAB may be used to connect any one of the following:

• One Class B or one Class A Initiating Device Circuit
• One Class A or B circuit for 2-wire Smoke Detectors
• One Class A or B Notification Appliance Circuit

Standard Features

  • 15 modules in one
  • Multiple applications including Class A or B device circuit wiring, Class A or B 2-wire smoke detector circuits and delayed latching (retard) for waterflow alarm applications.
  • The installer selects one of up to 15 “personality codes” to be downloaded from the loop controller.
  • 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.
  • Agency Listings: UL, ULC, CSFM, MEA
