SIGA-CC2A, SIGA-MCC2A EST modules.
SIGA-CC2A and SIGA-MCC2A Single/Dual Input Signal Modules are part of EDWARDS's Signature Series system. They are intelligent analog addressable devices used for connecting, upon command from the loop controller, supervised Class A or Class B signal or telephone circuits to their respective power inputs.

SIGA-CC2A, SIGA-MCC2A EST modules

• Class A or B Operation • Supports three- and four-state telephones • Dual input (riser) select Use for connecting supervised 24 Vdc Audible/Visible signal circuits, or 25 and 70 VRMS Audio Evacuation and Telephone circuits to their power inputs. • Ring-tone generator When configured for telephone circuits, the SIGA-CC2A/ MCC2A generates its own ring-tone signal eliminating the need for a separate ring-tone circuit. • Plug-in (UIO) or standard 2-gang mount UIO versions allow quick installation where multiple modules are required. The 2-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 or a laptop PC; there are no switches or dials to set. • Ground fault detection by address Detects ground faults right down to the device level.
