Assistance Alarms.

system, disabled refuge call system or as a combined system when both fire
telephones and disabled refuge points are required.

and multi story buildings by local codes of practice such as BS9999.
Disabled refuge systems are recommended in buildings where public or disabled
staff gain access to any floor other than the ground floor using lifts.

A VoCALL 5 line exchange unit comprises of 2 functional blocks, the VoCALL 5 line
exchange unit and the outstations, (Type A, Type B, Jack Points and Emergency

suit the application.
VoCALL 5 has been designed on a star topology consisting of spurs formed

MICC 200m per leg) to each outstation. Please follow local codes of practice for
cable types and wiring routes.
1.3 Retrofit compatibility

compatibility must be carried out on the outstations, and any units which do not
function as expected must be replaced with new units. This advice also applies to all
roaming handsets.
