GSA-CT2 Dual Input Module (One-gang standard mount)
The GSA-CT2 ⭐
✅ 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 the Signature loop controller during system configuration. The input modules gather analog information the initiating devices connected to them and convert it digital signals. The module’s on-board microprocessor analyzes the signal and decides whether or not to input an alarm.
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-CT2 rated for high temperature environments Suitable for attic installation and monitoring high temperature heat detectors.
• 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 Signature Program/Service Tool. There are no switches or dials to set.
• Ground fault detection by address Detects ground faults right down to the device level.

Application
The duty performed by the GSA-CT2 is determined by their sub-type code or “Personality Code”. The code is selected by the installer depending upon the desired application and is downloaded the loop controller.
Two personality codes can be assigned to the GSA-CT2. Codes 1, 2, 3 and 4 can be mixed on GSA-CT2 modules only. For example, personality code 1 can be assigned to the first address (circuit A) and code 4 can be assigned to the second address (circuit B).
Installation
GSA-CT2: modules mount to North American 2½ inch(64 mm) deep 1-gang boxes and 1½ inch (38 mm) deep 4 inch square boxes with 1-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
