Edwards EST SIGA-CT1 Single Input Monitor Module

Edwards EST SIGA-CT1 Single Input Monitor Module



The SIGA-CT1 Single Input Module and SIGA-CT2/SIGA-MCT2 Dual Input Modules are intelligent analogue 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 analogue information from the initiating devices connected to them and convert it into digital signals. The module’s onboard microprocessor analyzes the signal and decides whether or not to input an alarm.


The SIGA-CT1 and SIGA-CT2 mount to standard North Ameri- can 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 SIGA-MCT2 is part of the UIO family of plug-in Signature Series modules. It functions identically to the SIGA-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 Edwards enclosures.


Standard Features


  • Multiple applications

Including Alarm, Alarm with delayed latching (retard) for water- flow applications, Supervisory, and Monitor. The installer selects one of four “personality codes” to be downloaded to the module through the loop controller.


  • SIGA-CT1 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.
