An audible warning cue is smoke alarm system. A sound energy produces a resonating wave to a closest molecule within the selected material. We know that dense materials produce a better sound than less dense materials. Smoke alarm system is an integrated equipment, consist of the audible signals, rings, sirens customized voice and intense flashing lights. Maintenance of this system must be done regularly as per the schedule. Generally, the quarterly check and test are recommended. It has a switch as a test button. This switch must be checked and tested at least once in a month to certify that alarm is working in a right condition. Bursting of the fire nozzle is recommended at least once in a year. The purpose of this system is when building caught fire, quickly apartment would be filled by the smoke and the toxic gases. It would be a far before the flame and the heat can spread. Major incidents happen in fire by the toxic gas only. Research evident that many victims are never even burnt by flames. This smoke alarm system is the most trusted protection in regards to this life threating events. At very initial stage it can sense the tiny presence of smoke and initiate the sounds alarm. It provides the escape window much before the smoke could capture.
a) An accurately scaled draft Reflected Ceiling Plan (RCP) for this room AND one section view of the ceiling void.
b) The issues to be considered in the laying out, installation and maintenance of the services.
c) Technologies incorporated in the design
d) Essential Fire safety cardinals

Proposed
Remarks
Building in a flood area
BP 1. 4
only applies to buildings in which people are likely to sleep that are located in a flood hazard area, i.e. a Class 2
Spread of fire
CF2(c)
in Class 2 parts used as sole-occupancy units that provide sleeping
accommodation to allow sufficient time for the occupants to safely evacuate;
Spread of fire
CP2(a)(ii)
aims to minimise the risk of people in Class 2 buildings, for example, if they were sleeping and consequently having difficulty escaping a fire. For this reason, CP2(a)(ii) requires that sole-occupancy units and corridors used for escaping be provided, to the degree necessary, with protection to avoid the spread of fire.
Type of construction required
C1.1(a)
sets out the minimum type of fire-resisting construction required by the Deemed-to-Satisfy Provisions for all Class
2 buildings.
C1.1(b)
requires building elements to comply with Specification C1.1 for the appropriate type of construction.
Class and height (rise in storeys)
Table C1.1
explains that the required type of construction of a building depends on risk levels as indicated by the Class of
building and the building’s height as indicated by the rise in storeys. Note that there could be other factors that need to be
considered. For example, C2.2 and Table C2.2 examine the maximum permissible size of fire compartments or atriums in
buildings for specific types of construction.
Class 4 parts of buildings
C1.6
The reason for requiring the same FRL for a Class 4 as a Class 2 building is because the two different classifications have similar fire loads. It should be noted that the Type of construction required for a Class 4 part is determined in accordance with C1.3.
Public corridors in Class 2 buildings
C2.14
In a Class 2 building there is a very high risk that building occupants will be asleep when a fire occurs. It is important that they be able to safely evacuate the building. To assist in the safe evacuation, long public corridors should not become smoke logged.
Bounding construction: Class 2
To maintain the fire performance of walls surrounding a sole-occupancy unit and corridors used as egress routes in Class 2 buildings, C3.11(a) and (b) requires the...
