TABLE 1: SHORT CIRCUIT PROTECTION - UL 864 9TH EDITION REQUIREMENTS
NOTICE TO USERS, INSTALLERS, AUTHORITIES HAVING JURISDICTION, AND OTHER INVOLVED PARTIES
This product incorporates field-programmable software. In order for the product to comply with requirements in the Standard for Control Units and
Accessories for Fire Alarm Systems, UL 864, certain programming features or options must be limited to specific values or not used at all as indicated below.
PROGRAM FEATURE OR OPTION
Disabling short circuit protection
when a single power supply is shared
by multiple NACs
BEFORE INSTALLING
This information is included as a quick reference installation guide. Refer to
the appropriate control panel installation manual for detailed system infor-
mation. If the modules will be installed in an existing operational system,
inform the operator and local authority that the system will be temporarily
out of service. Disconnect the power to the control panel before installing the
modules. This system contains static sensitive components. Always ground
yourself with a proper wrist strap before handling any circuits so that static
charges are removed from the body. The housing cabinet should be metallic
and suitably grounded.
NOTICE: This manual should be left with the owner/user of this equipment.
GENERAL DESCRIPTION
The SC-6 Six Supervised Control Module is intended for use in an intelligent
alarm system. Each module is intended for switching applications involving
AC, DC, or audio, which require wiring supervision. A common SLC input is
used for all modules. Each module has its own address. A pair of rotary code
switches is used to set the address of the first module from 01 to 94. The re-
maining modules are automatically assigned to the next five higher addresses.

SETTINGS PERMITTED IN UL 864
Enable short circuit protection when a single power supply is
shared by multiple NACs. Short circuit protection can be disabled
only when a power supply is not shared by multiple NACs.
Provisions are included for disabling a maximum of three unused modules
to release the addresses to be used elsewhere. Each module also has panel
controlled green LED indicators. The panel can cause the LEDs to blink, latch
on, or latch off.
In order to synchronize strobes, horn/strobes, and speaker/strobes, a SYNC-1
accessory card (sold separately) must be used with the SC-6. See the SYNC-1
installation manual for details on how to install.
Each module has terminals for connection to an external supply circuit for
powering devices on its NAC.
Each supply must be power limited and its voltage/current limits must be at
or below those specified.
There is a short circuit protection monitor for each module. This is provided to
protect the external power supply against short circuit conditions on the NAC.
