1. The phone must be located no more than 48" from the floor.
This requirement is designed to keep elevator phones within the reach of wheelchair
passengers.
2. If the telephone has a handset, the handset
cord must be at least 29" long.
This is to allow physically impaired passengers to operate the
phone from a wheelchair. If you were allowed to simply install
a longer coiled cord you would encounter two problems. First,
a long coiled cord is difficult to retain inside an elevator
phone cabinet–they fall out every time the cabinet door is
opened. Secondly, once they fall out, they are easily severed
by the sharp edges on the cabinet door. That means repeat-
ed replacement costs for you, and periods of noncompliance.
Also, in elevators and ARAs (Areas of Rescue Assistance),
coiled cords are an invitation to vandalism and total phone
destruction. For example, the standard procedure for attempt-
ing to vandal-proof a modular-ended coiled cord is to
remove the squeeze tab from the modular plug. This makes
theft difficult without a special removal tool. Unfortunately, it
also frustrates vandals and ultimately results in them ripping out the entire phone,
causing far more destruction to the phone, than if the modular clip were left intact.
An armored cable handset, the kind you find on many outdoor pay telephones, vast-
ly reduces the risk of handset theft and vandalism. A 29" armored cable is just about
impossible to store inside an elevator telephone cabinet. Armored cables cost far
more than standard coiled cords.
3. Emergency phones must be hearing aid compatible.
• They must be capable of a volume increase of at least 12 decibels with a
maximum increase of 18 decibels above normal.
• If a hearing aid compatible, volume-control handset is used, the volume increase
may exceed 18 decibels, provided that an automatic reset is provided to lower the
volume for the next use.
Hearing-aid compatible handsets with volume controls are available from most tele-
phone dealers. They are usually stocked in the "G" handset design (old style handset
with round earpiece and mouthpiece), and the "K" design (newer design with square
earpiece and mouthpiece). Unfortunately, they are rarely available in the dial-in-
handset design. Both the "G" and "K" series hearing-aid, volume-control handsets
are considerably more expensive than standard handsets. Lose one of these handsets
to vandals, and the replacement cost will exceed the phone's value.
