APPENDIX C
RELEASING APPLICATIONS
C-1 INTRODUCTION
The PEGAsys LV system can be used for agent release,
pre-action sprinkler and deluge sprinkler control applica-
tions. When used with UL Listed, compatible actuating and
initiating devices, the PEGAsys LV system meets the re-
quirements of the following standards:
NFPA 12 CO
2
Extinguishing Systems
(High Pressure)
NFPA 12A HALON 1301 Extinguishing Systems
NFPA 13 Sprinkler Systems
NFPA 15 Water Spray Systems
NFPA 16 Foam-Water Deluge and Foam-Water
Spray Systems
NFPA 17 Dry-Chemical Extinguishing Systems
NFPA 17A Wet-Chemical Extinguishing Systems
NFPA 2001 Clean-Agent Fire Extinguishing Systems
C-2 PROGRAMMING
The PEGAsys LV system can support one releasing out-
put which is used to control releasing functions. MP1 is
the CCM releasing output which is optionally programmable
to be a signal release output. The PCS program is used to
program the system for all functions, including releasing.
Table C-1. Abort Styles
Note: The abort function will not work if a time delay value is not entered in the EOC programming for the protected
area. Maximum allowable delay is 60 seconds as allowed by UL 864. The abort input is not intended to be used
for a service disconnect.

For complete details, refer to the PCS manual. The follow-
ing features are supported for releasing functions.
C-3 ABORT
The abort function is a feature which manually stops a dis-
charge time delay. The PEGAsys LV supports four styles
of aborts, as listed in Table C-1.
C-4 DELAY
The time-delay period is an installer programmable value
which begins to count down after the automatic release
criterion has be attained for a particular protected area.
The time-delay can be programmed for activation after one
or two alarm occurrences.
C-5 SOAK
The soak function is used to automatically shut off the re-
leasing solenoid at a pre-determined time after the mapped
inputs activate them. It may be programmed as a 10-minute
or 15-minute soak period. This soak function is for use in
NFPA 16 applications only.
C-6 SPECIAL MODULE TYPES
The PEGAsys LV provides specific styles of devices which
have special releasing functions. These devices are:
