The BT Consort 1 + 4 is a single line multi-feature telephone system (i.e. 1 exchange line plus up
to 4 units) comprising 1 main and up to 3 extension units into which standard telephones
are plugged to provide a plan 105/107 replacement with hold, enquiry, transfer, bell off,
buzz, intercom and paging facilities.
Made by Rathdown Industries Limited.
APPROVAL STATUS
Approved for plug in connection to the PSTN or extension of a PBX. A locking bar MUST be
fitted to the Line Jack Units into which the Consort system cords (6 wire) are plugged.
This requirement applies to both PSTN and PBX connection. Consort is approved for DIY
wiring and is exempt from the pre-connection inspection and approved maintainer
requirements.
Maximum Main to Extension Unit cabling (using cable 2503F) is limited to 80 ohms maximum,
star or serial wired (80 ohms approximates to 275 cable metres). Any telephone approved to
BS6317 may be connected to the main or extension unit.
The main unit provides an earth recall signal of 300 + 10 m secs. A modified main unit
with an early recall signal of 1.2 seconds is available for systems (e.g. PABX 4)
requiring a longer recall signal.
INSTALLATION
Ensure that the line voltage setting switches on the main unit are in the correct position
for DEL/PABX working - 50 volt (position A) or PABX working (older Mitel systems
and PMBX 1) - 25 volt (position B).
The main unit can be identified as it is the only unit to have a mains adapter and night service button.
Each extension unit must have it's own unique address and this is set on a bank of switches on the rear of each extension
unit. The address of the main unit is always 4 and does not need to be set.
Wiring
All 6 wires must be connected at every socket within the extension cabling. One of the LJU's must be a master.

ADDITIONAL INFORMATION
Consort is not suitable for C-Wire supervision recall. If earth recall is
needed then connect an earth to pin 4 on the master LJU. TBR is provided by the
telephone used.
Locking bars MUST be fitted to the Consort system LJU's (2/3A's). A locking bar is not
required on the DEL or PABX LJU. Locking bars are included in the Consort Kits.
The PSU reduces the supply voltage to 18v rms.
LD and MF telephones can both be used - dependant on the main exchange.
