MGC SGM-1004S 4 NAC Output Module
Module Mounting Locations
The SGM-1004S is a 4 NAC output module that provides synchronization and
various modes of operation including signal silence mode (silencing audible
signals but not visual signals), suite isolator mode, and bell cut mode. A
maximum of 3 SGM-1004S can be installed in each node. Each SGM-1004S can
provide its own audible and visual synchronization (the four outputs of one
SGM-1004S are synchronized).
Mount the SGM-1004S in the same locations as other adder modules. Refer to
Figure 1 below for mounting locations.
Note : Only the last circuit adder module should have a jumper plug on its continuity jumper; the continuity jumper on all the other adder modules must be open.

LEDs
There are four green LEDs (labeled I1, I2, I3, I4) on the board, one for each signal zone. The LED illuminates or flashes following the signal rate sent to its zone. It is off when the system is normal and it illuminates when a signal zone is activated. The LED does not reflect what is happening on the signal zone, just that it is receiving data to activate that signal zone.

Refer to the field wiring instructions for the SGM-1004A in the respective
fire alarm panel manual.

Note:
The terminal blocks are depluggable for ease of wiring.
The SGM-1004S NACs are either all power limited or all non-power limited. See
“Synchronization” on page 4.
All power limited circuits must use type FPL, FPLR, or FPLP power limited
cable.
See “NAC Ratings” on page 6 for the ratings.
Note:
FleX-Net™ FX-4000, MMX™-4000, FleX-Net™, MMX™, FX-2000: Maximum voltage drop
should not exceed 3.3 volts for Class A and 3.7 volts for Class B.
FX-6000MNS-CH: Maximum voltage drop should not exceed 3 volts.
FA-1000: Maximum voltage drop should not exceed 3.3 volts.
Synchronization
Use DIP Switch 1, SW1 to SW4, to set the SGM-1004S to no sync (the panel
provides synchronization) or to sync according to a manufacturer’s protocol.
If the panel is set to Temporal 3, and the DIP Switch 1 is set to No sync,
then the field wiring terminals are not power-limited. All the field wiring
terminals on each SGM-1004S must be either all power-limited or all non-power
limited.
If DIP Switch 1 is set to a manufacturer protocol, then the field wiring
terminals are power-limited.
! Attention:
If the field wiring terminals are power-limited, attach the included label
NP-8308 to the field wiring terminals.
If the field wiring terminals are not power-limited, discard the included
label NP-8308.
Maintain a separation of 1/4” (6.4 mm) minimum between power-limited and non-
power-limited wiring at all times. Reserve the left side of the enclosure for
all non-power-limited wiring.
Operation
There are four modes of operation for this module.
Basic Mode
The basic mode of operation does not involve any bell cut relay or suite isolators connected to the signal zones, and no signal silence. For this case, leave jumpers JW1, JW2, JW3 and JW4 off, leave SW5, SW6 and SW7 of DIP Switch 1 off, leave the switches of DIP Switch 2 off, and do not connect anything to terminal blocks TS1 or TS2.
Bell Cut Mode
This mode provides bell cut operation which allows the silencing of bells or horns.
- Connect TS1 to a bell cut relay (for details see LT-666 QRM-1001 Bell Cut Module Installation and Operating Instructions).
- Set SW7 of DIP Switch 1 ON.
- Use DIP Switch 2 to select which of the four NACs will silence its bells and horns when the bell cut relay is active. You can select more than one NAC.
Suite Isolator Mode
This mode is used when suite isolators are connected to the signal circuits.
- Connect TS1 to a common alarm relay. See Figure 3.
- Set SW7 of DIP Switch 1 OFF.
- Place a jumper according to the table below.
Place jumper on | JW1 | JW2 | JW3 | JW4 |
---|---|---|---|---|
If there is a suite isolator on | zone 4 | zone 3 | zone 2 | zone 1 |
! Attention : Discard jumpers on zones that are not configured for suite isolators.
Refer to LT-875 CSIS-202A Supervised Signal Isolator Module Installation Instructions or LT-879 CSIS-202A1 Supervised Signal Isolator Module Installation Instructions.
For further information on bell cut relays or suite isolators, please refer to the specific fire alarm panel manual or the isolator instruction manual.
Figure 3 Suite Isolator Mode Wiring
Signal Silence Mode
This mode is used if audible signals are required to be silenced but visual signals should continue to function when signal silence is activated on the panel.
- Connect TS2 to a NAC output that is configured as a continuous silenceable signal (not strobe). See Figure 4.
- Configure the NACs on the SGM-1004S that require horns to be silenced as non-silenceable strobes using the panel configurator.
- Set DIP switch 1 for the strobe manufacturer (see “DIP Switch 1”).
- Set SW5 of DIP Switch 1 ON.
When signal silence is active, the SGM-1004S changes its output signals from both horns and strobes active to only the strobes active.
