Module - Class-B Input (CT1 / CT2)

The GSA-CT1 Single Input Module and GSA-CT2/GSA-MCT2 Dual Input Modules are intelligent analog addressable devices used to connect one or two Class B normally-open Alarm, Supervisory, or Monitor type dry contact Initiating Device Circuits (IDC).  The actual function of these modules is determined by the “personality code” selected by the installer. This code is downloaded to the module from the Signature loop controller during system configuration.  The input modules gather analog information from the initiating devices connected to them and convert it into digital signals. The module’s on-board microprocessor analyzes the signal and decides whether or not to input an alarm. 

The GSA-CT1 and GSA-CT2 mount to standard North American 1-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-MCT2 is part of the UIO family of plug-in Signature Series modules. It functions identically to the GSA-CT2, but takes advantage of the modular flexibility and easy installation that characterizes all UIO modules. Two- and six-module UIO motherboards are available. All wiring connections are made to terminal blocks on the motherboard. UIO assemblies may be mounted in Listed enclosures.

Standard Features

  • Multiple applications - Including Alarm, Alarm with delayed latching (retard) for waterflow applications, Supervisory, and Monitor. The installer selects one of four “personality codes” to be downloaded to the module through the loop controller
  • GSA-CT1HT is rated for high temperature environments - Suitable for attic installation and monitoring high temperature heat detectors.
  • Plug-in (UIO) or standard 1-gang mount - UIO versions allow quick installation where multiple modules are required. The 1-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
  • Stand-alone operation - The module makes decisions and inputs an alarm from initiating devices connected to it even if the loop controller’s polling interrogation stops. (Function availability dependent upon control panel)
  • Ground fault detection by address - Detects ground faults right down to the device level
  • The GSA-CTxx operate at a temperature range of 32 °F to 120 °F (0 °C to 49 °C)
  • The GSA-CT1HT operates at an expanded temperature range of 32 °F to 158 °F (0 °C to 70 °C)
  • Agency Listings: UL, ULC, CE, FM, CSFM, MEA
