Scope:

This Standard sets forth the minimum requirements for the design, installation, inspection, testing and maintenance of residential fire warning systems for use within dwelling units and care occupancies not requiring fire alarm systems conforming to CAN/ULC-S524, Installation of Fire Alarm Systems. 

NOTE: This Standard is intended to apply to both required and voluntary residential fire warning system installations. 

This Standard specifies how such residential fire warning systems shall be installed to perform their intended function. 

This Standard is not intended to specify the type and extent of residential fire warning systems.

The installation of fire detection and alarm devices not covered by the requirements in this Standard shall be in accordance with good engineering practice and the manufacturer’s published installation instructions.

Project need:

Changes to CAN/ULC S540 are being proposed to address multiple topics: -Clarify the proper connection of fire detectors that require a separate connection to the auxiliary power supply; -Amend Ground Fault definition to align with CAN/ULC 524, and other terms such as Tamper Devices; -Power Supplies for RFWS, addressing that all power supplies for a RFWS must be hard-wired; -Installation height for manual stations to align with ULC 524, and; -Other editorial corrections
