The Edwards SIGA-CT1 Single Input Module is an addressable device used to connect a Class B initiating device circuit (IDC) to a Signature loop controller (ULC)

The module requires one address on the signaling line circuit (SLC). Addresses are assigned electronically. There are no address switches.

The Edwards SIGA-CT1 Single Input Module, SIGA-CT1HT High Temperature Single Input Module and SIGA-CT2/SIGA-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.

Edwards SIGA-CT1 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.

• 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.

• Ground fault detection by address

Detects ground faults right down to the device level
