The Deafgard fire alarm vibrating fire alarm warning system is an ideal product to help hotels and other residential facilities comply with the DDA.


Deafgard is a stand alone, wirefree fire alarm listening device for deaf and hard of hearing people.

 

Deafgard consists of a wire-free, battery powered, acoustically triggered bedside unit with a high intensity strobe, and a vibrating pillow pad. The connected vibrator pad is placed under the pillow. When the Deafgard unit hears the fire alarm the under-pillow pad vibrates waking the sleeper, whilst the activated flashing strobe and LCD provides a complementary visual indicator in case the guest is in the room but not in bed. The result is an immediate and effective motion and visual trigger, which signals that the fire alarm is sounding, allowing the individual to leave the building to a place of safety.

 

The fundamental principal is based on the requirement for fire alarms in residential accommodation to generate a minimum volume of sound at the bedhead. It is this required continuous level of sound which the Deafgard responds to. 

 

As no installation is required, units may be held at reception and issued upon request. The Receptionist should shows the guest how to operate the system before guest takes the Deafgard to their room.

 

A secondary but rather useful feature of the Deafgard is a vibrating alarm clock facility.

 

A Deafgard may certainly be used at home, but as it does not itself include a smoke/fire detector the house would require an appropriate fire alarm system with adequate volume at the bedhead.

So how does a DeafGard work?

The operation of a DeafGard relies on the installation of a building fire alarm to BS5839-1:2002, (Clause 16.2).

‘’The sound pressure level of alarm signals should be generally, throughout all accessible areas of the building not less than 65dB(A) . . . . . where the sound pressure level of background noise is greater than 60dB(A), the sound pressure level of the fire alarm signal should be 5dB above the sound pressure level of thebackground noise.’’

It also states:The sound pressure level of alarm signals ‘’should be not less than75dB(A) at the bed head within rooms in which the fire alarm system is intended to rouse people from sleep’’.

The DeafGard itself knows nothing about smoke or fire, it is the continuing sound of the building fire alarm which the DeafGard responds to. For those with a technical interest the DeafGard trigger level is 65dB SPL with a 4 second sampling rate. If the DeafGard detects 65dB 4 times in a row a fire alert will be activated.
