22 Gemini C-Series GEMC-NAC Extender Installation Instructions
Operating Humidity Range:
10% to 90% relative hu-
midity, from 32°F to 104°F (0°C to 40°C) non-
condensing.
Housing
The GEMC-NACXX comes complete with 7A power sup-
ply, enclosure and ample room for standby batteries. Two
models are available, as determined by the size of the en-
closure:
Enclosure Dimensions (W x H x D, Inches):
•
The
GEMC-NAC7S
uses the small housing with suffi-
cient room for two pair of 12V standby batteries
(model
GEMC-HSKIT1416
, size 14.25" x 16" x 5.25")
•
The
GEMC-NAC7L
uses the large housing with room
for four pairs of 12V standby batteries (model
GEMC-
HSKIT1425
, size 14.25" x 24" x 5.25")

JUMPERS
When used with a FACP, the jumpers on the GEMC-
NACXX circuit board are used as follows:
NAC ADDR
: Must be set to "zero" for this configuration
(no shunts across any of the jumpers)
NAC OPTIONS:
See chart on page 24. Each option is
detailed as follows:
•
Option "Zero"
allows any synchronized "Smart" for-
mat to be passed through Input 1 to NAC's 1 & 2 di-
rectly and Inputs 2 to NAC's 3 & 4 directly
•
Option 1
allows Input 1 to be a strobe input and al-
lows Input 2 to be a bell input where the bell causes
NAC's 1 & 3 to give a Temporal output and 3 & 4 to
be a latched (strobe) output
•
Option 2
allows Input 1 to be a strobe input and al-
lows Input 2 to be a bell input all NAC's 1 -4 will output
the Wheelock synchronized horn/strobe format.
•
Option 3
allows Input 1 to be a strobe input and al-
lows Input 2 to be a bell input with all NAC's 1 -4 will
output the System Sensor synchronized horn/strobe
format.
NAC OPTIONS
Jumper 4 "
Offset
" must be shunted
when more than total combined 4A output is required for
synchronized outputs. Shunting Jumper 4 offsets
NAC's 3 and 4 from NAC's 1 and 2 by .5 seconds to al-
low instantaneous current for the synchronized devices.
However, note that when shunted, the strobes and
horns must not be seen or heard from within the same
area.
NAC OPTIONS
Jumper 5 "
AUX PWR
" may be shunted
when a single constant 24 auxiliary output is required.
When shunted, NAC 4 will be on all the time, thus allow-
ing auxiliary devices to be powered from the NAC 4 ter-
minal.
Note:
Only one output may be used for Auxiliary
power when using NAC configuration jumper option
"zero" and wiring a constant power limited 12 or 24V to
one or both inputs. Aux power outputs are 2A maxi-
mum in alarm. Maximum 1.1A standby. When config-
ured for 24V Auxiliary Power, it is a Special Application
output only listed with the GEMC-24VR. See battery
charts for battery requirements.
EZM ADDR
: Use to configure the integral 4-Zone EZM
to send the status of a device (AC ON/OFF, BATTERY
GOOD/TBL, GROUND FAULT and TAMPER) to the C-
Series control panel.

*
Indicates trouble condition. When trouble (open, short or ground) occurs on a specific output, the corresponding red output LED, (NAC 1 - NAC 4) will
blink. Loop trouble will de-energize the normally energized trouble relay (
OUT RELAY 7
) within 30 seconds.
**
Indicates trouble condition memory. When a trouble condition restores, the units red output LED, (NAC 1 - NAC 4) will blink with a shorter and distinctly
different duration. The green input LED(s) will be off (normal condition). To reset the memory, press and hold the "
CLEAR
" button (momentary-on) for
two seconds. The LED(s) will extinguish.
Note: If indicating circuits have been restored, memory reset is not required for normal operation of the unit.
