• The FX-NAC is used to supervise the 24 VDC riser only. When using the FX-NAC as a
riser supervision module, it cannot be used for notification appliances or included in a
correlation group.
• The following procedure must be done using the Configuration Utility (CU).
To program the sounder base for T3T4 Fire/CO:
1. Configure the detectors as follows:
Message Line 1: Description of the installed detector location
Device Type: Primary sensor type + CO alarm
Base Type: Sounder
Follow: None, Head, Alarm, Alm + Vrfy, or Alm + PreAlm
Follow CO: No or Yes (only displays if Follow is set to Alarm, Alm + Vrfy, or Alm + PreAlm)
2. Configure the FX-NAC module as follows:
Device type: Supervised Output
Message Line 1: 24VDC_RISER
Message Line 2: SOUNDER_CKT_1
3. Configure Correlation Group 001 as follows:
Add/Remove Zone: As required
Add/Remove NAC: As required
Add/Remove Device: Add all alarm signal initiating devices corresponding T3T4 device
Channels as described below
To create correlations for T3T4:
1. Channel 1 must be correlated with proper sounder base as output to any primary alarming
type inputs.
2. Channel 2 can be correlated with proper sounder base as output to secondary element
(CO) of detectors.
3. If both Channel 1 and Channel 2 are correlated as outputs to a sounder base, then
Channel 1 pattern overwrites the Channel 2 pattern.
Notes
• Channel 1: T3T4-TC3 (fire): The device at address visible on T3T4 device.
• Channel 2: T3T4-TC4 (CO): The device at address above plus one.
• CO alarm signals are required to activate TC4 CO evacuation signals. CO supervisory or
CO monitor signals are not allowed to activate CO evacuation signals.
