Gemini C-Series GEMC-NAC Extender Installation Instructions 7
WIRING
Notification Appliance Circuit Supervision
Install a 2.2K end-of-line (EOL) resistor across the last
notification appliance on each Notification Appliance Cir-
cuit to be supervised.
The Notification Appliance Circuits will not respond
unless zones or events are assigned to them.
The Gemini C-Series control panel monitors the Notifica-
tion Appliance Circuits wiring for open and short circuit
faults while the output is inactive. If these troubles occur,
a specific indication at the GEMC-FK1 keypad identifies
the NAC number; in addition, if programmed, the control
panel will send a report to the central station. These
NAC circuits also have the ability to be disabled, and
have their disabled status reported to the central station.
PROGRAMMING FOR CLASS A
The External Output Assignment screen provides the
ability to select Class A operation for NAC 1 / NAC 2
and/or Class A operation for NAC 3 / NAC 4. When se-
lected, the associated NAC's (1 & 2 or 3 & 4) must be
programmed to activate for identical events.
Each NAC circuit has a programmable 32 character de-
scription that can be associated with the circuit (displays
on the Fire keypad when the menu option "Output Di-
rectory" or "Outputs Disabled" is selected).
