Vigilant GSA-CT2 Dual Input Module

The Vigilant GSA-CT2 is a commercial dual input module designed for compatible Vigilant Signature Series fire alarm systems. It connects one or two normally open dry-contact initiating device circuits to a Signature Loop Controller, allowing conventional alarm, supervisory, waterflow, and monitoring devices to report individually through the addressable fire alarm system.

Each input channel can be programmed independently using one of four personality codes. This allows the module to monitor different device types from the same installation, such as a waterflow switch on one circuit and a valve tamper switch on the second circuit. This product is intended exclusively for commercial fire alarm installations.

Product Functions

• Monitors up to two normally open dry-contact circuits
• Provides two supervised Class B initiating device circuits
• Supports alarm device monitoring
• Supports delayed waterflow alarm monitoring
• Supports supervisory device monitoring
• Supports non-latching equipment status monitoring
• Reports each input through a separate module address
• Provides continuous Signature loop communication
• Detects ground faults at the device level

Electrical & System Information

The GSA-CT2 operates from the compatible Signature Data Circuit at 15.2–19.95 VDC and uses two module addresses, one for each input channel. Electronic addressing is assigned through the Signature Loop Controller, compatible programming software, or a Signature service tool, eliminating mechanical address switches or rotary dials.

Each input is supervised with a 47 kΩ end-of-line resistor and supports normally open dry-contact initiating devices. The two channels can use different personality codes, allowing separate alarm, delayed alarm, supervisory, or monitor functions within the same module.

Features

• Commercial dual input module
• Two Class B dry-contact input circuits
• Electronic addressing
• Uses two Signature module addresses
• Four selectable personality codes
• Automatic device mapping
• Stand-alone alarm decision capability
• Ground-fault detection by address
• Onboard microprocessor
• Self-diagnostics and history logging

Mounting & Design

The GSA-CT2 mounts in a standard North American 2½-inch-deep single-gang electrical box or a 1½-inch-deep 4-inch square box equipped with a single-gang cover and compatible mounting plate.

The module includes removable terminal connections suitable for 12–18 AWG conductors. Its compact wall-plate design makes it suitable for remote locations where a single dual-input module is required.

Protection & Applications

Suitable for:

• Manual Pull Stations
• Waterflow Alarm Switches
• Valve Tamper Switches
• Conventional Heat Detectors
• Fan Status Contacts
• Damper Position Contacts
• Door Position Contacts
• Pressure Switches
• Commercial Fire Alarm Systems

Compatibility

Compatible with:

• Vigilant Signature Series Fire Alarm Systems
• Vigilant Signature Loop Controllers
• Signature Data Circuits
• Normally Open Dry-Contact Alarm Devices
• Normally Open Supervisory Devices
• Normally Open Monitor Contacts
• GSA-MP Series Mounting Plates
• Compatible Single-Gang Surface Boxes

Always verify compatibility with the installed Vigilant fire alarm control panel, Signature Loop Controller, firmware version, assigned personality codes, and connected initiating devices before installation. The module does not support conventional two-wire smoke detectors.
