| NFPA-72 | 18.5.5.2 | Where low ceiling heights do not permit wall mounting at a minimum of 2.03 Meter wall mounted visual notification appliances shall be mounted within 150 mm of the below Ceiling. | |

| NFPA-72 | 18.5.5.4 | Visual notification appliances listed for mounting parallel to the floor shall be permitted to be located on the ceiling or suspended below the ceiling. | |

| NFPA-72 | 18.4.6.1 | Sleeping Area : Sound level at least 15 dBA above average ambient sound or 5 dBA above maximum sound level for duration of at least 60 sec or Sound level at least 75 dBA, which is greater measured at pillow level with door closed. Low-frequency 520 Hz preferred (better arousal) | |
| NFPA-72 | 18.4.4.1 | Industrial / high-noise / Mechanical rooms : Sound level at least 15 dBA above average ambient sound or 5 dBA above maximum sound level for durstion of at least 60 sec | |
