SIGA-CC2 Dual Input Signal Module
Installation Guide

Description

The SIGA-CC2 Dual Input Signal Module is an addressable device that connects one of two risers to a Class B supervised output circuit.
When activated, the module connects the output circuit to the Riser 1 or Riser 2 input. The input can be either 24 VDC (to operate polarized audible and visible signal notification appliances), or 25 or 70 VRMS (to operate audio evacuation speakers). Typically, the Riser 1 input connects to the ALERT channel and the Riser 2 input connects to the EVAC channel. The module does not provide signal synchronization. To meet UL 864 requirements for horn and strobe signal synchronization, you must install a Genesis Signal Master module. This module does not provide supervision of the riser; the fire alarm panel provides this function. The SIGA-CC2 module requires two addresses on the signaling line circuit (SLC). Addresses are assigned electronically. There are no address switches. Diagnostic LEDs provide visible indication of the state of the module through the cover plate:

• Normal: Green LED flashes
• Alarm/active: Red LED flashes

Personality codes

Use the personality codes described below to configure the SIGA-CC2 module. See Table 1 for listing information.
Table 1: Personality codes

supervised output
(Class B)| | |

Personality code 7: Riser selector – supervised output (Class B). Configures the SIGA-CC2 module as a one – or two – input, signal power (24 VDC) or audio evacuation (25 or 70 VRMS) riser selector. The output circuit is monitored for open or shorted wiring. If a short exists, the control panel inhibits the activation of the signal circuit, so the riser is not connected to the wiring fault.

Installation

Install this device in accordance with applicable national and local codes, ordinances, and regulations.
Notes

• The module is shipped from the factory as an assembled unit; it contains no user-serviceable parts and should not be disassembled.
• This module does not operate without electrical power. As fires frequently cause power interruption, discuss further safeguards with the local fire protection specialist.

To install the module:

1. Write the address assigned to the module on the label provided, and then apply the label to the module. Remove the serial number label from the module, and then attach it to the project documentation.
2.  Wire in accordance with “Wiring” on page 2.
3.  Using the self-tapping screw provided, attach the wall plate to the module. See Figure 1.
4.  Using the four machine screws, attach the wall plate and module to the electrical box.

5. 4 × 1/2 self-tapping screw

Protection from transient spikes
For installations in which the output circuit connects to electromechanical bells or horns, install a bipolar transient protector (P/N 235196P) to protect the module from transient spikes caused by switching inductive loads. Locate bells and horns at least 6 ft. (1.8 m) from the module.
To install a bipolar transient protector:

1. Install the transient protector across the output circuit inside the electrical box with the module.

See Figure 2. Figure 2: Bell circuit showing bipolar transient protector placement

Wiring
Wire this device in accordance with applicable national and local codes, ordinances, and regulations.
General wiring notes

• Refer to the Signature loop controller installation sheet for SLC wiring specifications.
•  Each terminal on the module is limited to a single conductor.
• Test resistors are supplied with the SIGA-CC2 to prevent trouble signals on unused circuits during installation. When connecting field wires, remove the test resistors and install a UL/ULC Listed 47 kΩEOLR at the end of the circuit.
•  The module does not support conventional smoke detectors.

Riser wiring notes

• For maximum line impedance, refer to the installation manual for the fire alarm panel. Maximum circuit capacitance is 0.1 µF.
• If the riser is used for more than one notification zone, install in accordance with the survivability from attack by fire requirements in NFPA 72 National Fire Alarm and Signaling Code.
• The SIGA-CC2 module does not supervise the riser; the fire alarm control panel provides this function.

To wire the module:

1. Verify that all field wiring is free of opens, shorts, and ground faults.
2. Strip 1/4 in. (about 6 mm) from the ends of all wires that connect to the terminal block of the module. When stripping wire ends, exposing more wire may cause a ground fault; exposing less wire may result in a faulty connection.
3. Connect the field wires. See Figure 3 and Figure 4.

3.  Power-limited unless connected to a nonpower-limited source. If the source is nonpower-limited, eliminate the power-limited mark and maintain a minimum of 0.25 in. (6.4 mm) space from powerlimited wiring. For other mounting methods, see enclosure and bracket installation sheets to maintain separation of power limited and nonpower-limited wiring. The wire size must be capable of handling fault current from nonpower-limited source. — or — Use type FPL, FPLR, FPLP, or permitted substitute cables, provided these power-limited cable conductors extending beyond the jacket are separated by a minimum of 0.25 in. (6.4 mm) space or by a nonconductive sleeve or nonconductive barrier from all other conductors. Refer to the NFPA 70 National Electrical Code for more details.
4. If using a G1-P Genesis series horn while connected to a compatible fire alarm control panel, a CDR-3 Bell Coder must be used to comply with NFPA 72 standard alarm evacuation signal.
