Apartment Isolation

A common requirement of local

authority and housing association,

apartment isolation simplifies fault

finding while adding an extra layer

of protection to a system. In

the event of a fault

within an

apartment, or

the wiring to an

apartment

the line

isolation will

ensure

that only

one

apartment

is affected allowing the

remaining apartments on the

systems to function as normal.

The VX2200 uses optional 4

apartment audio isolation cards

and for video systems a piggy back

board serves to protect the

additional cables required for video,

both saving space and simplifying

connections.

Each card includes 10 LED’s

to assist an engineer

should a fault occur on

the system.

Channel in

use, voltage fault and bus

fault conditions are all signalled. To

further assist the engineer all

connections are plug type to allow

simple swap out while testing.

The cards are designed to be either

d

istributed around the building or

contained in a control cabinet in

one or more locations.

DDA (Disability

Discrimination Act)

The VX2200 has many DDA

features including:-

LCD displays - for the hard of

hearing. This can help guide them

through the call and inform them

when the door has been released.

Voice annunciation - a useful

feature for the visually impaired

which verbally announces the

message displayed on the LCD

display.

Induction coil - available for the

telephone handsets and the door

panels. They are used by hearing aid

wearers to inductively pick up the

sounds and conversation from the

system.

Strobe lights - used in an

apartment to visually signal that

the intercom telephone is ringing.

Telephone interface - enables a

conventional telephone in an

apartment to be used on the

intercom system.Very useful

especially when the conventional

telephone has already been

adapted to a user’s special needs.

High contrast buttons - standard

on the digital panels and optional

on all others.
