British Telecom supplied on both rental and outright sale.
The Answer and Recording Machine No. 102A, sales name Falcon, came with a New Plan (PST) plug-ended cord and was only used in the following situations:-
  • Direct exchange lines.
  • Telephone extensions wired to New Plan plug and socket.
  • PBX extensions
    - PABX extensions must be switched through to an exchange line, i.e. on night service.
    - PABX extensions when on 'direct night service'.

The following procedure should be adopted before commencing a facility check:-

(a) Press the "Automatic Answer Off" button.

(b) Insert two new mini-cassettes. The 2 x 15 minute cassette into the "Announcement Tape" position and the 2 x 30 minute cassette into the "Message Tape" position.

(c) Press the "Automatic Answer ON" and "Message Rewind", buttons both tapes will now home and the machine is ready for testing.


a) To Record an Announcement
Press and hold the "Announcement Record" button. While this button is pressed record the announcement via the internal Electret microphone. Speak 100 to 150 mm (4 to 6 inch) from the left and side of the machine. On completion of the announcement release the button; the cassette will continue to record a few seconds of tone to mark the end of the announcement before rewinding automatically. The announcement can be up to one minute in duration.

A second announcement may be recorded on the reverse side of the cassette by turning it over then pressing the "Automatic Off" button to rewind the tape then follow the same procedure as for the first side.

b) To Check an Announcement
Press the "Announcement Check" button and the announcement will be played back through the internal loudspeaker. The volume should be adjusted for comfortable listening.

c) To Set Machine Ready to Answer Calls
Press the "Automatic Answer ON" button and the "In-use" indicator will glow for a few seconds before the "Ready" indicator glows showing the machine is ready to accept incoming calls.

d) Operation
When an incoming call is received ringing from the parent exchange will continue for approximately 10 seconds allowing time to answer the call if required. When the machine answers the call the "In use" indicator will glow and there will be a minimum of 3 seconds delay to detect paytone if the call is from a coin box. Transmission of the announcement will start:-

  1. At the end of the 3 seconds period if the line is quiet and there is no paytone on the line.
  2. At the end of paytone if paytone is present.
  3. After approximately 25 seconds if paytone or noise is continuous.

At the end of the announcement the incoming caller will hear a short tone signal after which a message of 30 seconds, one minute or 3 minutes duration can be recorded. The incoming message time is pre-selected by using the 3 position slide-switch at the rear of the machine - when viewed from the rear of machine the right-hand switch corresponds to 30 seconds - centre, one minute and the left-hand setting 3 minutes. At the end of the fixed message time the caller will hear a further short tone indicating that the time has elapsed and that the machine has disconnected from the telephone line. The "In use" indicator will go out and the "Ready to Accept" call indicator again glow.

NOTE: When the machine is connected to a parent exchange that gives a short disconnection when the caller clears - known as a "K" break - the machine may detect this signal and release the telephone line. In all other cases the machine will busy the line and record dial or park tone for the pre-selected message time. The machine will not stop to a continuous tone or quiet after 10 to 15 seconds as does the Answering and Recording Machines 1A and 101A.

To take over the call once the machine has answered lift the telephone hand- set and press the "Automatic Off" button and the machine will revert to the idle state. If the machine is not stopped it will record a two-way conversation for the duration of the pre-selected message time. However, it should be noted that if the machine is connected to a modern Call Connect system provided with a constant current transmission feed the low impedance of the machine may starve the telephone of transmission current. This is not a monitor facility and this information should not be given to the customer.

e) To Listen to Recorded Messages
If the machine has answered a call the "Call Taken" indicator will glow. To listen to the recorded messages press and release the "Rewind" button and wait until 1 the tape has fully rewound. Press and release the "Play" button to hear the recorded messages using the volume control as necessary.

Messages can be replayed singly by the skilful use of the "Play, Rewind" buttons.

f) To Erase Messages
Previous messages are erased as new messages are recorded, however should it be necessary to erase messages for security reasons press and hold both "Message Play and Rewind" buttons.

g) Machine Ready Lamp Flashes
This indicates the machine has answered or tried to answer at least one call and is caused by one or more of the following conditions.

  1. The announcement tape does not contain an announcement
  2. The announcement tape is jammed, broken or missing
  3. The message tape is full and unable to take any more messages
  4. The message tape is jammed, broken or missing

Most faults are due to worn tapes or dirty Record/Play heads. Both tapes should be changed before any maintenance is attempted to ensure these are not the cause of the fault.

1) Tape Heads It is not necessary to dismantle any part of the machine to clean the tape heads. The tape ejector key should be pressed and the cassette removed to expose the tape heads. Any good quality proprietary head cleaner or methylated spirit may be used. Dampen a soft piece of cloth with the fluid, wrap around the blunt end of a pencil and gently wipe the tape heads clean.

2) Base Cleaning Cleaning fluids such as petrol or carbon tetrachloride which might damage the plastic surfaces must not be used. A soft cloth dampened with water is quite adequate.

3) Lubrication All moving parts are lubricated during manufacture and need no further lubrication.

4) Machine Fails to Switch ON If the machine fails to switch on, indicated by the "POWER ON" LED not glowing, the mains plug should be withdrawn from the supply socket and the two mains fuses tested. A 3 amp fuse is located in the moulded mains plug and a 200 ma delayed action (Type 72/0.2 item code 314339) is located in the case of the mains lead transformer. If the fuses are not ruptured the machine base should be removed by unscrewing the base screws located in the corners and the input voltage measured at Pl BROWN and P2 BLUE. This should be 17 to 19 volts AC. No input indicates a faulty supply lead or transformer which should be changed separately. Do not change the complete machine. If the input voltage is correct, but the machine fails to switch on then a visual inspection should be made for any obvious defect. If the fault is not observed the machine should be changed for a maintenance replacement using the existing supply leads and transformer.

5) Machine Appears Serviceable, but will not Answer This could be caused by a faulty line jack or line cord. The line voltage, typically 50 volts should be measured at T2 RED and T5 WHITE. The Blue and Green wires are spare and connected to T2 and T4 respectively. If faulty the line cord - Cords Inst 4/502 should be changed and the machine re-tested.

6) Machine "Ready" LED Goes out If the mains supply is interrupted or the "Automatic Answer Off" button pressed the machine will revert to the idle state and will not answer calls.

The following pre-set adjustments are included within the machine and under normal circumstances they should not be touched apart from RV1 (Machine Volume Control). Two separate circuit boards are involved, they are:-

(i) Small Printed Circuit Board - Accessed when complete chassis is removed from machine.

RV1 Volume Control - Adjustable by customer

RV2 Announcement level to line

RV3 End of Announcement tone frequency - 1 kHz

(ii) Main Printed Circuit Board - Accessed with machine base removed.

RV1 Motor Speed - Announcement Tape

RV2 Motor Speed - Message Tape

RV3 Machine Answer Delay

RV4 Paytone Over-ride - Not provided on all machines.

Line terminals T4-T4A have a relay break contact connected to them and their intended use if for a 4 wire extension, i.e. 'C' wire control on 2/PMBX's.

Product Bulletin
Issued: 10/82


This bulletin introduces a range of telephone answering and telephone answering/recording machines into the range of products available to our customers. Two models will be introduced, both housed in Ambassador styled cases and supplied in three attractive colours:- Dark Brown, Mid Grey and Stone.

Announcements are pre-recorded on to a standard 15 minute mini-cassette using the integral electret microphone located on the lower left hand side of the machine fascia. The mini-cassette may be turned over allowing an alternative announcement to be recorded or additional mini-cassettes can be purchased from most office equipment shops so that a library of announcements can be built up to meet varying circumstances. Each announcement can last up to 60 seconds, the duration being limited by an electronic timer within the machine and may be checked by being played back though an integral loudspeaker.

In addition to the facilities provided by the Eagle the Falcon records incoming messages on to a standard 30 minute mini-cassette. Three message lengths can be set by the user so that incoming messages of 30 seconds,1 minute or 3 minutes duration can be recorded. Both announcements and messages can be played back through a loudspeaker incorporated within the machine.

It is planned to launch the range as follows:
Eagle - August 1982
Falcon - July 1982

Eagle - September 1982
Falcon - August 1982
