Mark-III AM & FM Rebroadcast System


The IBMS is a monitor component of the Mark-III AM & FM Radio Rebroadcast operation in tunnels. The IBMS is a AM & FM tuner based system with external control.

It allows monitoring of multi-zone systems (1, 2 or more tunnel bores or tubes, depending on configuration). The IBMS offers a practical option for hearing what is actually being rebroadcasted in the tunnel. This allows tunnel personnel and operators to assess that the emergency messages are being heard by the commuters inside the tunnel.
