**************************************************************************
Addressable and control modules shall be installed in the outlet box or
adjacent to the device they are controlling. If a supplementary
suppression releasing panel is provided, then the monitor modules shall he
mounted in a common enclosure adjacent to the suppression releasing panel
and both this enclosure and the suppression releasing panel shall be in the
same room as the releasing devices. All interconnecting wires shall be
supervised unless an open circuit or short circuit abnormal condition does
not affect the required operation of the fire alarm system. If control
modules are used as interfaces to other systems, such as HVAC or elevator
control, they shall be within the control panel or immediately adjacent to
it. Control modules that control a group of notification appliances shall
be adjacent to the first notification appliance in the notification
appliance circuits. Control modules that connect to devices shall
supervise the notification appliance circuits. Control modules that
connect to auxiliary systems or interface with other systems (non-life
safety systems) and where not required by NFPA 72, shall not require the
secondary circuits to be supervised. Contacts in suppression systems and
other fire protection subsystems shall be connected to the fire alarm
system to perform required alarm functions as specified in [Section [13930A
WET PIPE SPRINKLER SYSTEM, FIRE PROTECTION] [13935A DRY PIPE SPRINKLER
SYSTEM, FIRE PROTECTION] [13945A PREACTION AND DELUGE SPRINKLER SYSTEMS,
FIRE PROTECTION]] [_____] [NFPA 72], as indicated on the drawings and as
specified herein.
3.2
OVERVOLTAGE AND SURGE PROTECTION
3.2.1
Power Line Surge Protection
All equipment connected to alternating current circuits shall be protected
from surges per IEEE C62.41 B3 combination waveform and NFPA 70. Fuses
shall not be used for surge protection. The surge protector shall be rated
for a maximum let thru voltage of 350 Volts ac (line-to-neutral) and 350
Volt ac (neutral-to-ground).
3.2.2
Low Voltage DC Circuits Surge Protection
All [IDC] [IDC, NAC, and communication cables/conductors], except fiber
optics, shall have surge protection installed at each point where it exits
or enters a building. Equipment shall be protected from surges per IEEE
C62.41 B3 combination waveform and NFPA 70. The surge protector shall be
rated to protect the 24 Volt dc equipment. The maximum dc clamping
voltages shall be 36 V (line-to-ground) and 72 Volt dc (line-to-line).
3.2.3
Signal Line Circuit Surge Protection
All SLC cables/conductors, except fiber optics, shall have surge
protection/isolation circuits installed at each point where it exits or
enters a building. The circuit shall be protected from surges per IEEE
C62.41 B3 combination waveform and NFPA 70. The surge protector/isolator
shall be rated to protect the equipment.
3.3
GROUNDING
Grounding shall be provided by connecting to building ground system.
