Signal Modules with Class A Operation

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.
