Fact
The
Standard is referenced in the National Building Code and
National Fire Code
The National Building Code and the National Fire Code requires
that a fire signal receiving center and a fire protective
signaling system at a protected property meet the requirements
of CAN/ULC-S561, Installation and Services for
Fire Signal Receiving Centres and Systems.
In addition, the Standard for the installation of fire alarm
systems –CAN/ULC-S524-06, Installation of Fire Alarm Systems –
requires that the interconnection
between a fire alarm system control unit and a fire signal
receiving center comply with the same CAN/ULCS561. These two
Standards are not only separately referenced in the Code, but
are integral to each other in that conformance to CAN/ULC-S561
is directly linked to CAN/ULC-S524.
