All critical mobilising systems require backups in the event of
primary landline; PSTN, ISDN, ADSL or radio link failure.
The 2A-SR receiver assures this backup by providing an
alternative trigger for most mobilising system encoders.
Using conventional wide area radio paging, (in the event of
normal link failure), a simple phone call or network paging request is all that
is needed to initiate mobilisation.
The 2A-SR’s design means that this product can be used as a
direct replacement to existing receivers carrying out this specific function.
