Armoured Unshielded SECUREX® II FAS Fire Alarm, Signal and Security System Cable FAS
Standards
National  CSA C22.2 N° 208, File No. LL23462
Description

 #20 to #12 AWG solid bare copper conductors (stranded conductors optional).  Multiconductors:  3-50 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.

Outer 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 Part 1 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.

Selling delivery information

CAUTION
In case of fire, well-maintained early warning smoke detectors will give an alarm long before non-metallic coverings become combustible.

However, in spite of the widespread and longstanding use of PVC in residential and commercial buildings, all purchasers of PVC insulated/jacketed products should be aware of the following:

Non-metallic coverings of electrical cables can burn and may transmit fire when ignited.
Burning non-metallic coverings may emit gases which are toxic and may generate dense smoke.
Emission of acid gases may corrode metal in the vicinity; e.g., sensitive instruments and reinforcing rods in cement.
