Overview
SIGA-CC2A and SIGA-MCC2A Single/Dual Input Signal Modules
are part of EST'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.
Module power inputs may carry polarized 24 Vdc current to oper-
ate audible and visible signal appliances, or 25 and 70 V
RMS
to
operate audio evacuation speakers and firefighter’s telephones.
The SIGA-CC2A/MCC2A may be configured as a three-state or
four-state telephone riser selector.
The loop controller assigns an address to the module automati-
cally. No addressing switches are used. A custom address can be
assigned using a laptop computer.
Diagnostic LEDs provide visible indication of the status of the
module when the cover plate is removed:
• Normal — green LED flashes
• Alarm/active — red LED flashes
The CC2A mounts in a two-gang electrical box. The MCC2A
plugs into a UIO motherboard. Both modules provide the same
functionality.
The actual operation of the module is determined by the “person-
ality code” selected by the installer. It is downloaded to the module
from the Signature loop controller during system configuration.
Standard Features
• 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/MC-
C2A 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 con-
troller 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.
