22、 have been available formany years, and are specified in BS EN 14604 (smoke alarms), BS 5446-2 (heatalarms) and BS EN 50291-1 (carbon monoxide alarms). These devices areintended to warn of the presence of a potentially dangerous condition byemitting a loud piercing sound. However, people with hearin
23、g loss might not beable to adequately hear such an alarm sound.There are recognized methods of alerting deaf and hard of hearing people,including the use of vibratory, visual alarm and low frequency audible devices.To provide a fire or carbon monoxide warning for those who are deaf or hardof hearing
24、, it has become common practice for such devices to be coupled todomestic alarms. For example, vibrating pads can be used to awaken deaf orhard of hearing people, and visual alarms to alert those already awake, in theevent of the associated alarm(s) activating. There is therefore an increasing needf
25、or standardization of such alarm systems. This part of BS 5446 addresses thatneed by specifying requirements for fire and carbon monoxide alarm systemsthat include fire and carbon monoxide alarms and associated warning devicesused in dwellings to warn deaf and hard of hearing people. This part of BS
26、 5446does not claim to provide an exclusive or definitive solution to the problem ofproviding reliable protection to people with impaired hearing. It is recognizedthat other techniques or products might be developed which would currentlyfall outside the scope of this part of BS 5446.This part of BS
27、5446 includes tests and requirements for vibratory, visual alarmand low frequency audible devices, for fire and/or carbon monoxide alarms byreference to BS EN 14604, BS 5446-2 and BS EN 50291-1, and for theinterconnections of these components. The tests specified in this part of BS 5446are type test
28、s and are not intended as manufacturers tests to maintainuniformity of quality in production, which is dealt with in the BS EN ISO 9000series. While the tests are intended to assess the most important features of thedesign and construction of the components of alarm systems for deaf and hardof heari
29、ng people, they cannot remove the necessity for regular inspection andmaintenance, which is essential for reliable operation.The sound from fire and carbon monoxide alarms is intended to alert peoplewhen they are either awake or asleep, but for a person with significant hearingloss, a combination of
30、 vibration, flashing light and sound is generally required inorder to provide an equivalent level of protection. Some medical conditionsmight require specialist medical advice as to appropriate alarm equipment.Since any fire or carbon monoxide alarm that forms part of a system for deafand hard of he
31、aring people is required to conform to BS EN 14604, BS 5446-2or BS EN 50291-1, it will incorporate a functioning sounder. BS 5446-3 specifiesrequirements for the additional vibration and flashing light functions and anylow frequency sounders.To assist in the selection of an alarm system appropriate
32、to an individuals needs,a grade system has been devised for guidance purposes. The grade system iscovered in more detail in the Commentary on Clause 4 and Annex A.BRITISH STANDARD BS 5446-3:2015 The British Standards Institution 2015 11 ScopeThis part of BS 5446 specifies requirements and test metho
33、ds for componentsand their means of interconnection (e.g. by electrical wiring or by radio links)intended to be assembled to create fire and/or carbon monoxide alarm systemsfor deaf and hard of hearing people, for the purpose of life safety in dwellings.NOTE 1 Although this part of BS 5446 provides
34、the specification for alarm systemsfor dwellings, it is recognized that these systems, or components thereof, might beused in other situations, where similar requirements could be anticipated.NOTE 2 Equipment conforming to this part of BS 5446 might not be suitable foruse in boats, due to the corros
35、ive atmosphere. It might however be suitable for usein other leisure accommodation vehicles (LAVs).NOTE 3 The systems specified in this part of BS 5446 are specifically intended togive warning in the event of fire, or carbon monoxide emissions. However, it isrecognized that systems might also incorp
36、orate devices to alert deaf and hard ofhearing people to other events, such as door bell, telephone, alarm clock, babyalarm, etc., that are outside the scope of this part of BS 5446.This part of BS 5446 does not cover medical vibrating devices as definedin BS EN ISO 9999; these are covered by BS EN
