Fire Alarm, Signal and Security System Cable FAS 105
STANDARDS
National : CSA C22.2 N°208, File No. LL23462
DESCRIPTION
20 to 12 AWG solid bare copper conductors (stranded conductors optional). Multiconductors: 3 to 50 armoured. Conductor #3 of multiconductor cables is coloured green, suitable for bonding purposes. Armoured constructions must have a minimum of 3 conductors, using the green conductor for bonding only.
Inner jacket is 105°C flame retardant red PVC. Optional aluminum/mylar shield with tinned copper drain wire. Rip cord under jacket for safe, easy jacket stripping.
Interlock aluminum or galvanized steel armour with or without overall jacket.
Application
SECUREX® II is a 300V 105°C cable specifically designed for the interconnection of security system elements: including fire protective signaling devices such as smoke and fire detectors, fire alarms, and two-way emergency communication systems.
Code Requirements
Although SECUREX® II cable is fire rated to CSA FT4 requirements, Section 32 of the Canadian Electrical Code requires the use of mechanical protection for fire alarm cable installations in non-combustible buildings.
RULE 32-102
Subrule (1)
All conductors of a fire alarm system shall be:
installed in metal raceway of the totally enclosed type; or
incorporated in cable having a metal armour or sheath; or
installed in rigid non-metallic conduit where embedded in at least 50mm of masonry or poured concrete, or installed underground; or
installed in electrical non-metallic tubing where embedded in at least 50mm of masonry or poured concrete.
Subrule (2)
Notwithstanding Subrule (1), conductors installed in buildings of combustible construction in accordance with the Rules of Section 12 shall be permitted to be:
nonmetallic sheathed cable; or
fire alarm and signal cable; or
installed in a totally enclosed nonmetallic raceway.
As a cost-effective alternate to metal raceway, SECUREX® II is now available in popular sizes and conductor counts with aluminum interlock armour.
