<br />Application Notes - Canada <br />(Based in part on 1995 Canada National Building Code) <br /> <br />The fire alarm signal sound pressure level shall not exceed <br />110 dBA in any normally occupied area. The sound pressure <br />level from an audible signal in a floor area used for occupancies <br />other than residential occupancies shall not be less than 10 dBA <br />above ambient levels, and never less than 65 dBA. In sleeping <br />rooms the sound pressure level from an audible signal shall not <br />be less than 75dBA when any intervening doors between the <br />device and the sleeping room are closed. Audible signal devices <br />shall be installed not less than 1.8 m to the center of the device <br />above the floor (per CANtU LC S524). <br /> <br />Light Output Profiles <br /> <br />-Intensity (Cd) <br />-UL Umlt (Cd) <br /> <br />15 cd (horizontal) <br />o <br /> <br />c <br /> <br /> <br />lO <br /> <br />180 <br /> <br />15cd(vertical) <br />o <br /> <br /> <br />-90 <br /> <br />180 <br /> <br />c. <br /> <br />30 cd (horizontal) <br />o <br /> <br />75 <br /> <br /> <br />The fire alarm audible signal shall be supplemented by fire alarm <br />strobes in any floor area where the ambient noise level exceeds <br />87 dBA, or where the occupants of the floor area use ear protective <br />devices, are located within an audiometric booth, or are located <br />within sound insulating enclosures. This also applies to assembly <br />occupancies in which music and other sounds associated with <br />performances could exceed 100 dBA <br /> <br />Strobes shall be installed in a building so that the flash from one <br />device is visible throughout the floor area or portion thereof in <br />which they are installed. For maximum safety, EST recommends <br />that strobes be installed as per the guidelines shown here under <br />Strobe Spacing. <br /> <br />110 cd (horizontal) <br />o <br /> <br /> <br />-90 <br /> <br />180 <br /> <br />60 cd (horizontal) <br />o <br /> <br />90 <br /> <br /> <br />110 cd (vertical) <br />o <br /> <br />75 <br /> <br /> <br />90 <br /> <br />.go <br /> <br />-90 <br /> <br />180 <br /> <br />60 cd (vertical) <br />o <br /> <br />90 <br /> <br /> <br />90 <br /> <br />-90 <br /> <br />90 <br /> <br />105 <br /> <br />.105 <br /> <br />-90 <br /> <br />180 <br /> <br />105 <br /> <br />105 <br /> <br />180 <br /> <br />30 cd (vertical) <br />o <br /> <br />90 <br /> <br /> <br />180 <br /> <br />75 cd (horizontal) <br />o <br /> <br />75 <br /> <br /> <br />.75 <br /> <br />-90 <br /> <br />180 <br /> <br />75 <br /> <br />90 <br /> <br />-90 <br /> <br />90 <br /> <br />105 <br /> <br />105 <br /> <br />180 <br /> <br />75 cd (vertical) <br />o <br /> <br />90 <br /> <br /> <br />-90 <br /> <br />90 <br /> <br />180 <br /> <br />Issue 5 <br /> <br />EDWARDS SYSTEMS TECHNOLOGY <br /> <br />Utersture Sheet #85001 -0529 <br />Not to be used for installation purposes. <br /> <br />Page 3 of 6 <br />
