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 VRMS 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.

Application
The operation of the SIGA-CC2A/MCC2A is determined by their sub-type code or “Personality Code”. The code is selected by the
installer depending upon the desired application and is downloaded from the loop controller. The following personality codes can be used
with the SIGA-CC2A/MCC2A:
When using the SIGA-CC2A/MCC2A as a single input module
Personality
code 5
Riser selector Class B, single input. The module operates as a single riser selector for signal power (24 VDC) or au-
dio evacuation (25 or 70 VAC). The output circuit is monitored for open or shorted wiring. If a short exists, the control
panel inhibits the activation of the audible or visible signal circuit, so that the riser is not connected to the wiring fault.
Personality
code 27 Riser selector Class A, single input. Operates the same as personality code 5, except wiring is Class A.
Personality
code 6
Riser selector Class B three-state, single input, ring tone. The module operates as a riser selector for a three-state
(open, normal, active) firefighter’s telephone. When a telephone handset is plugged into its jack or lifted from its
hook, the module generates its own ring-tone signal. A separate ring-tone riser is unnecessary. The module sends
this signal to the control panel to indicate the presence of an off-hook condition and waits for the system operator to
respond to the call. When the system operator responds, the ring-tone signal is disabled.
Personality
code 28
Riser selector Class A three-state, single input, ring tone. Operates the same as personality code 6, except wiring is
Class A.
Personality
code 26
Riser selector Class B four-state, single input, ring tone. The module operates as a riser selector for a four-state
(open, normal, active, trouble) firefighter’s telephone. Only one telephone can be used with the CC2A at any given
time. When a telephone handset is plugged into its jack or lifted from its hook, the module generates its own ring-
tone signal. A separate ring-tone riser is unnecessary. The module sends this signal to the control panel to indicate
the presence of an off-hook condition, and waits for the system operator to respond to the call. When the system
operator responds, the ring-tone signal is disabled.
Personality
code 29
Riser selector Class A four-state, single input, ring tone. Operates the same as personality code 26, except wiring is
Class A. Not compatible with Warden Phones.
Personality
code 25
Class B auto synchronization output. The module operates to provide synchronization of compatible fire alarm sig-
nals across multiple zones. The output wiring is monitored for opens and shorts. If a short exists, the module inhibits
the activation of the audible/visual signal circuit so that the riser is not connected to the wiring fault.
Note: You may use nonsynchronous fire alarm signals with or instead of compatible synchronized fire alarm signals, but the opera-
tion of these devices will not comply with UL 1971.
Personality
code 19 Class A auto synchronization output. Operates the same as personality code 25, except wiring is Class A.
When using the SIGA-CC2A/MCC2A as a dual input module:
Personality
code 7
Riser selector Class B, dual input. The module operates as a riser selector for dual signal power (24 Vdc) or dual
audio evacuation (25 V or 70 V) riser selector. The output circuit is monitored for open or shorted wiring. If a short
exists, the control panel inhibits the activation of the audible or visible signal circuit, so the riser is not connected to
the wiring fault.
Personality
code 30 Riser selector Class A, dual input. Operates the same as personality code 7, except wiring is Class A.

Installation
SIGA-MCC2A: mount the UIO motherboard inside a suitable
Edwards enclosure with screws and washers provided. Plug the
SIGA-MCC2A into any available position on the motherboard and
secure the module to the motherboard with the captive screws.
Wiring connections are made to the terminals on the motherboard
(see wiring diagram). UIO motherboard terminals are suited for
#12 to #18 AWG (2.5 mm2 to 0.75 mm2) wire size.

SIGA-CC2A: mount to North American 2-1/2 inch (64 mm) deep
two-gang boxes and 1-1/2 inch (38 mm) deep 4-inch square
boxes with two-gang covers and SIGA-MP mounting plates. The
terminals are suited for #12 to #18 AWG (2.5 mm2 to 0.75 mm2)
wire size.
Electronic Addressing - The loop controller electronically address-
es each module saving valuable time during system commissioning.
Setting complicated switches or dials is not required. Each module
has its own unique serial number stored in its on-board memory.
The loop controller identifies each device on the loop and assigns
a “soft” address to each serial number. If desired, the modules can
be addressed using a laptop computer. No addressing switches are
used.
Warnings & Cautions
These modules do not provide supervision of the riser. The fire
alarm panel must provide this function.
These modules do not support conventional 2-wire smoke detec-
tors.
These modules will not operate without electrical power. As fires
frequently cause power interruption, we suggest you discuss
further safeguards with your fire protection specialist.
Edwards recommends that this module be installed according to
latest recognized edition of national and local fire alarm codes.
Compatibility
These modules are compatible only with Edwards EST3 control
panels, the Signature Series Loop Controller, and Genesis and
Enhanced Integrity signals.
Testing & Maintenance
The module’s automatic self-diagnosis identifies when it is defec-
tive and causes a trouble message. The user-friendly maintenance
program shows the current state of each module and other perti-
nent messages. Single modules may be turned off (de-activated)
temporarily, from the control panel.
Scheduled maintenance (Regular or Selected) for proper system
operation should be planned to meet the requirements of the
Authority Having Jurisdiction (AHJ). Refer to current NFPA 72 and
ULC CAN/ULC 536 standards.

Meets UL1971 synchronization requirement. All signal-
ing devices signal within 0.01 seconds of each other for
a period of at least two hours while maintaining a one
hertz signal rate. (For a list of compatible devices, see
“Compatibility”).
Note: For synchronization, the maximum resistance
between any two devices is 20 Ω. See the voltage
