This section provides an example of hardwiring a NACext to a host panel using two NAC inputs from
the host panel. Two NAC inputs from the host allows the host panel to separately control the
NACext’s A/Vs, turning off the audibles on signal silence and turning off the visuals when a system
reset occurs.
•
Wire the visual side of the A/Vs to NAC1. Wire the audible side to NAC3.
•
Configure host NAC connected to Input 1 as Off on Reset. Configure the host NAC connected to
Input 2 as Off on Silence
•
Set switches 1, 2, and 3 on SW2 to the OFF position. This configures the NACext so that NACext
NACs 1 & 2 (Visuals) are associated with host Input 1 and NACext NACs 3 & 4 (Audibles) are
associated with host Input 2.
•
Set Switch 7 on SW2 to the ON position. This causes the NACext NACs associated with Input 1
(i.e., NACs 1 & 2/Visuals) to track the state of the host Input.
•
Set Switch 6 on SW2 to the OFF position. This causes the NACext NACs associated with Input 2
(i.e., NACs 3 & 4/Audibles) to use the NACext’s locally generated signaling pattern. To set the
locally generated signaling pattern, set Switch 5 on SW2 to the appropriate setting (ON =
Marchtime; OFF = Temporal).
