Bell Unit RB-I -- The RB-1 is a self powered bell unit which generates signaling sound in greater
volume (80dB). Hooked up to the communication line in the same manner as the phone unit, it can be
utilized under severe noise conditions, or when using the phones across a long distance.
Master Switching Unit MP -- Up to 30 units of F/AL or TLP97 can be connected to the master
switching unit, so that communication can be made between the master unit and the slave phones, or
between slave phones, as selected on the master unit. Types MP-5, MP-10, MP-20, MP-30 are
available, each designation indicating the maximum number of phones to be connected.
Connecting Box -- A ruggedly constructed line-connector box which may be used even under
explosive atmospheres. With the use of special connector, TLP97 could be plugged or unplugged
instantly at the connecting box, which may be mounted on a wall, etc. for permanent installation, in a
designated site along the communication line.
Shock-absorbing Hanger -- A sturdy wall-mounting hanger with spring/rubber hook ideal for
installation in vehicles, ships, etc.
