Additional notes about Releasing:
The only programmable options for zones 1
– 5 are the relay settings when releasing is selected.
The 4-zone HCA panel does not have the capability of supporting a disconnect switch because the
panel only has four zones; there is no zone 5. The 4-zone HCA may be used for applications where
a disconnect switch is not required.
ALWAYS confirm with your AHJ before installing the
system!
When the disconnect switch is operated it will result in two messages on the HCA control panel:
1. A Supervisory event on zone 5
2.
A “NAC CIRCUIT 1 Trouble” event
When these events are present on the panel ensure that the disconnect switch is in the intended position.
The disconnect switch should always be in the ENABLED position except when service or maintenance is
being performed
.
