WIRING
NOTE: All wiring must conform to applicable local codes, ordinances, and
regulations.
1. Install module wiring in accordance with the job drawings and appropri-
ate wiring diagrams.
2. All wiring to the SC-6 is done via terminal blocks. In order to properly
make electrical connections strip approximately 5 mm of insulation from
the end of wire, sliding the bare end of the wire under the clamping plate
screw.
3. Set the address on the modules per the job drawing. Use the rotary code
switches to set the address of the first module (between 01 and 94).
The remaining modules are automatically assigned to the next five higher
addresses. For example, if the base address switch is set to 28, the next five
modules will be addressed to 29, 30, 31, 32, and 33.
DO NOT set the lowest address above 94, as the other modules will
be assigned to nonexistent addresses.
4. A shunt is provided to disable a maximum of three unused modules
(see Figure 1). Modules are disabled from the highest address and work
downward. If two modules are disabled, the lowest four addresses will
be functional, while the highest two will be disabled. For example, if
the shunt for Address Disable is placed on "two" and the base address

SIDE VIEW:
switch is set to 28, the modules will be assigned to 28, 29, 30 and 31,
disabling the higher two positions.
5. There is a short circuit protection option for each address. The board
is shipped with short circuit protection disabled for each address rep-
resented by six large shunts on the "Disable Short Circuit Protection"
area. To enable short circuit protection for an address, remove the corre-
sponding shunts from the "Disable Short Circuit Protection" area. When
enabled, the module will not switch power supply if a short circuit condi-
tion exists on a Monitored Output Circuit.
NOTE: Short circuit protection may only be enabled if power supply monitor-
ing is enabled.
NOTE: The synchronization feature is currently not supported.
6. There is a power supply monitor that must be enabled to facilitate short
circuit protection (see Figure 1). The module is shipped with power sup-
ply monitoring enabled represented by six large shunts on the pins of the
"Enable Power Supply Monitor" area.
NOTE: Monitored Output Circuit (M.O.C) refers to Notification Appliance
(NAC) on the PCB Legend.
NOTE: Place unused shunts on single pin to store on board for future use.
NOTE: SLC wiring is the top terminal block, notification appliance/power sup-
ply is the bottom for terminal T0.
WIRING NOTES
• All wiring must conform to applicable local code, ordinances or regulations.
• For easier wiring, assign all power-limited wiring to one side of the en-
closure rather than alternating with non power-limited.
MONITORED OUTPUT CIRCUIT WIRING AND SUPERVISION
Typical applications (figures 2 and 3) connect the positive terminal of the
Monitored Output Circuit to the monitored output circuit+ terminal and the
negative device terminal to the adjacent monitored output circuit- terminal.
Connect one (for each monitored output circuit) of the supplied EOL resistors
across the monitored output circuit+ and monitored output circuit- wires, at

POWER SUPPLY WIRING AND SUPERVISION
Table 3 gives an overview of how the power connectors, T0–T5 and T10–T15,
are interconnected by the circuit board (PCB). The external supply connection
points, at T0–T5, are marked by PS– and PS+ on the PCB legend. Pin 1 is
indicated by a dot next to T10–T16. The odd pins, on T10–T16, always con-
nect to PS– pins (e.g. PS–, of the +0 monitored output circuit, is connected to
T10–1 and T11–1). The even pins always connect to PS+ pins (e.g. PS+, of
the +5 monitored output circuit, is connected to T15-4 and T16-2).

All power supplies, external to the cabinet (in which the SC-6 is housed),
should be connected to T0–T5 which are suitable connectors for field wiring.
The 1 x 4 terminal blocks, shown on page 1, should be used to make these
connections.
All Monitored Output Circuits can be wired to be powered by separate exter-
nal supplies (figure 2 is typical), or a single supply (figure 3 is typical) can be
shared among multiple monitored output circuits. If a supply is to be shared,
between Monitored Output Circuits wired to a common PCB, use the short
power supply jumpers shown on page 1. The jumpers can be used on T11–
T15. Refer to Table 4 for jumper functions.A supply can be wired to be shared

among multiple PCBs in the same cabinet (figure 4 is typical). To share among
multiple PCBs: use the long power supply jumpers (shown on page 1) to con-
nect either T10 or T16, of one PCB, to either T10 or T16 of the other PCB.
An EOL relay must be used for every external power supply (figures 2–3 are
typical). The EOL relay coil should always be connected at the external power
supply input of the module which is connected farthest away from the power
supply. The EOL relay contacts should always be connected in series with
the Monitored Output Circuit wiring of the same module. The EOL relay coil
should be connected across the PS+ (red wire) and PS- (black wire) if it is
connected at T0 – T5. The EOL relay coil should be connected across adjacent
pins (red – even pin#, black – odd pin#), of the same connector, if T10 – T16
are used.
All cabling must comply with local standards or codes of practice. All external
power supplies must be voltage regulated with battery back-up.
