determine their performance under conditions of high and low tempera- lure corrosive and high humidity environments conditions of unusual vibration and other treatment which may con ceivably affect their normal response or sensitivity Similarly the test programme for a smoke detector begins with determination of its normal operating characteristics and continue with jn examination of the effects on these operating characteristics of subjecting the detector to unusual conditions and environments will be itieal of our discussion that one of the munis thai are examined is thai of sensitivity characteristics Although both the ionization or products of combustion type smoke detector and the pholo- lype smoke detector respond to an aerosol signature Ihe different principles involved in their operation have ihus far necessitated different approach in the assess ment of this feature in regard to respective types The level of combustion products type dclector is related lo the panicle density obtained a lime interval in the burning of four different materials while the level of photoelectric deleclor is related to degree of obscuration of a light beam These relation ships aie brought together by establishing comparative sensitivity levels and a range of sellings in the common environment of a laboratory smoke box with the smoke in this case produced by smoldering cellulose materials such as cotton wick or the punk slicks used in lighting fireworks Each type of smoke is to stability tests which examine the change in sensitivity of the device when exposed to such environments as rapid changes of tempera- lure humidity air and air pressure or the effect of of supply The sensitivity of he units is required to be such thai Ihey will not false alarm when subjected this treatment the present time ionization lype detectors are subjected lo die tests involving four different types of materials the combustion of which results in a range of particle types and sizes The materials burned are shredded newsprint poly styrene type packing material regular leaded gasoline and kiln dried fir strips The fire are conducted in a lest room with dimensions of some feet with a ceiling height of approximately Id feel The dclectors are required respond with an alarm to the lest fire condition within two minutes when spaced on a foot grid which places at feci from a point over the lop of the lest fire As is the case wnh testing programmes on alt classes of types lests and methods are under con- linual scrutiny or further refinement and in the case of smoke the possibility of fire tests as well as lor uniformity in the application of fire tests to both of detectors is currently under study Consideration is also being given to the inclusion of a variable flow sensitivity and a directionality test to evaluate the ability detectors respond to smoldering I ires where little heal is produced and con slow smoke movements are involved Other pans of the current testing procedure arc intended to he effect on the operation of the smoke detector of dust or their performance in potentially or after the simulation of effects abuse during handling or Iransit Each

incorporated in the sell contained units is also examined Detector Maintenance and Other Consideration Once we have decided upon the level of protection made our selection devices and selected their

equipment supplier Where economically feasible a maintenance contract mid be considered Further tests and by the manufacturer should From our discussion it will be appreciated that Ihere arc a number of considerations which need to be taken inlo account if we are to achieve a measure of ire safety in the home Apart from the selection of devices which have demonstrated an acceptable level of performance as well as their appropriate installation and regular maintenance No recommends the potential fire hazards in the home be minimized these hazards can be related to the statistics referred to earlier in this arliclel and lhat each household adopt a family escape plan The Standard warning offered by detectors may be wasted unless the family has planned in advance for rapid from their residence It recommends that drills be held so that all family members know what to do and that each person plan lor the possibility ol an exit out of the bed room window The Standard also nates that an exit from Ihe residence without requiring the opening of a bedroom door is essential To sum up No reasonable lire safely can be produced through a programme of 1 Minimizing fire hazards Providing a
