Scope:

These requirements cover electrically operated single and multiple station smoke alarms intended for open area protection in indoor locations and portable smoke alarms used as "travel" alarms in accordance with:

In Canada:

           a)    Installation of Smoke Alarms, CAN/ULC-S553;

           b)   National Building Code of Canada; and

           c)   National Fire Code of Canada.

In the United States:

  1. National Fire Alarm and Signaling Code, NFPA 72.

 

Project need:

CAN/ULC-S531 and ANSI/UL 217 are being merged into a single binational standard that can be used for Canada and the United States, Although the standards have mostly identical requirements, there are some that are unique to one country or the other – these requirements are denoted as country-specific. Highlights of this binational standard include harmonization of similar requirements between countries and the identification of national differences where harmonization is not possible. Enhanced marking requirements and clarifications are also included.
