Operation
5.2.3 INX Mode with Redundant Input
The system continuously monitors the SLC loop. If there is no activity for a notable time (80
seconds typical), an SLC trouble will be generated. While SLC trouble is active, if either of the
Sync Inputs are activated then all NAC outputs follow.
5.2.4 Independent Mode - Driving Signals and Strobes
The INX-10A can drive Signals and Strobes on separate NAC circuits.
To enabled Independent Mode set SW4 Bit 4-6 to 010, 110, 001, 101, or 011 and set SW5 Bit
1-3 to 100, 110, 001 or 101. When using a Two stage application SW4 bits 1-3 are required to
set the alert rate. For a comprehensive description of Independent Mode options see 6.5
Independent Mode Configuration Options on page 62.
5.3 Power Supply Modes
In addition to the operation modes above, some or all of the NAC outputs can be configured as
power supply outputs. The circuit ratings are same as the NAC circuits. Three types of power
output can be configured as described below:
5.3.1 NAC Outputs as Power Supply Outputs
Any NAC output can be configured as a power supply. SLC and Sync Inputs are ignored for
the power supply outputs.
For configuration information see Chapter 6.2.4 Setting Alert Rates, Evacuation Rates, NAC 5
Output Functions on page 36 and Chapter 6.2.5 Setting Strobe Types, NAC 1-3 Supply
Settings, NAC 4 Output Function on page 37.
5.3.2 NAC Outputs for Door Release
Only NAC 4 and/or 5 can configured for this option, NAC 4 or 5 are turned off (cut supply)
when any alarm input is active. This is used for devices which must be un-powered during
alarm like door releases.
For configuration information see Chapter 6.2.4 Setting Alert Rates, Evacuation Rates, NAC 5
Output Functions on page 36 and Chapter 6.2.5 Setting Strobe Types, NAC 1-3 Supply
Settings, NAC 4 Output Function on page 37.
5.3.3 NAC Outputs for 4 Wire Smoke Supply
Only NAC 4 and/or 5 can configured for this option, NAC 4 and 5 can be selected to turn-off for
2 seconds when an alarm ends (inputs inactive for more than five seconds). This is typically
used to reset four wires detectors.
For configuration information see Chapter 6.2.5 Setting Strobe Types, NAC 1-3 Supply
Settings, NAC 4 Output Function on page 37.
