The SIGA-MCC2A combines two signal risers into a single supervised output circuit while providing UL 1971 strobe synchronization, so notification appliances on the output flash and sound in step without a separate sync module.

Built for the commercial fire installer

Built on the same addressable dual-input riser architecture as the SIGA-CC2A, with synchronized output added so compatible Genesis and Integrity strobes on the circuit meet UL 1971 timing requirements (within 10 ms over a two-hour period). The output circuit is monitored for opens and shorts, and the panel inhibits activation if a wiring fault exists so the riser is never connected to a faulted circuit. No addressing switches - the loop controller assigns the address automatically.

Key features

  • Dual riser, single output with built-in synchronization
  • Class A wiring for supervised circuit survivability
  • UL 1971 strobe sync for compatible Genesis and Integrity signals on the circuit
  • Onboard diagnostic LEDs - green flashes normal, red flashes alarm/active
  • No addressing switches - address is assigned automatically by the loop controller

System requirements

Mounts to a North American 2-1/2 in. deep 2-gang box or standard 4 in. square by 1-1/2 in. deep box. For electromechanical bells or horns on the output, install a bipolar transient protector (235196P).

FAQs

What does this module do differently from the SIGA-CC2A?
It provides the same dual-riser, single-output selection, with UL 1971 strobe synchronization built in for compatible signals on the output circuit.
Which strobes synchronize with this module?
Compatible Genesis and Enhanced Integrity strobes on the same output circuit synchronize within 10 milliseconds over a two-hour period, meeting UL 1971.
Does this module supervise the riser wiring itself?
No. The output circuit is monitored for opens and shorts, but riser supervision is provided by the fire alarm panel.
Is a transient protector required?
Yes, when the output drives electromechanical bells or horns - install a bipolar transient protector (235196P) on the output circuit.
