Visible signal devices should be installed in a combination of regular suites and designated accessible suites in hotels and motels so that people who are deaf or hard of hearing can safely occupy either type of suite.
Visible signal devices are not required to be installed in all the rooms of the suite. The signal should be visible from any room in the suite, which can be accomplished by installing glazing panels between the rooms or additional visible signal devices.
In addition, CAN/ULC-S524, “Standard for Installation of Fire Alarm Systems,” requires that high-intensity strobes be used in sleeping rooms.
