3.17 JSDB-906 Jump Seat Distribution Box
3.18 PS-900-xx Pump Panel Station
3.19 PS-900-30-2 Pump Panel Station
The JSDB-906 is a single enclosure that provides six
jumpseat intercom-access/radio-listen headset positions.
The enclosure has six 20ft. unterminated cables and one
20ft. cable terminated in a four-conductor twist-lock
connector that plugs into the “REMOTES” port of the IM-900
or the “INTERCOM” port of the IM-900E. Four Tip-Ring-
Sleeve (TRS) panel mount jacks are provided with this
component and allow the installer to mount the box in a
remote or hidden location and run the cabling to individual
jumpseat locations.
Note: Panel Mount Jacks must be isolated from chassis
ground
The weatherproof PS-900-xx Pump Panel Station allows the use of a
mobile cab-mounted radio by the Engineer while at the pump panel.
The 15ft. coil cord of a CSB-900 Series Radio Transmit Headset is
plugged directly into the PS-900-xx, providing a fast and simple
connection. Since the volume control and Radio PTT are located in the
headset cup, no additional patch cables are required. The jack
receptacle is protected with a spring-loaded, weatherproof, flip-up
cover. The xx designates the length of shielded cable provided with the
standard PS-900-xx and is terminated with a twist-lock weatherproof
connector. The connector is plugged into the IM-900 port labeled
"PUMP PANEL”. On the IM-900E it is used in the “AUXILIARY INPUT”
port. Special care need to be taken in mounting the PS-900-xx to
retain the weatherproof integrity of the enclosure.
The weatherproof PS-900-30-2 Pump Panel Station is identical to
the PS-900-xx with the exception of the cable termination. This
version terminates with a three-conductor phone plug which can
be plugged into any of the Headset Ports on an IM-900 or IM-
900E. This Pump Panel Station is normally used with an IM-900E
system where a second Pump Station or a Turntable Station is
required.
