II is a modern processor controlled combined push button loudspeaking telephone twin tape
answering / recording machine with remote interrogation. The instrument has a Liquid
Crystal Display (LCD) that displays the time of day when not set to answer calls, and
indicates the number of messages or calls received when set to answer. A voice announcer (synthesiser)
records the day, time and number of messages received on the message tape, and gives voice
prompts over the line as an aid to remote interrogation. Other uses of the voice
synthesiser are to announce the day and time, also the numbers stored in the telephones 32
memory stores if the secret inhibit facility has not been used when storing the numbers in
Falcon II can be used as a desk top or wall mounted telephone answering machine. To wall

Falcon II contains no on-site serviceable parts and therefore maintenance is limited to
functional testing, checking the facility switches are set to provide optimum performance
to line, the condition of both the tapes and that the tape heads are clean.
If the machine fails completely the output voltage of the Transformer 750A should be
checked. The Transformer output is marked 13 volts AC, but will measure about 16 volts
when tested with the output open circuit.
Falcon II uses the same tape deck as Kingfisher II. Since the introduction of Kingfisher
II several complaints have been received about the machines not answering calls, or
answering and then not playing the outgoing message. It is possible that on occasions
Falcon II could exhibit the same symptoms. Details and solution follow:-
The OGM tape is worn, damaged or the capstan, pressure roller, sensing switch and heads
are dirty which prevents the tape from driving / winding correctly.
The solution to the above is to change the tape and clean the capstan, pressure roller,
sensing switch and heads. The details are included below under Routine Maintenance.
The user guide recommends that the customer changes both tape cassettes at six monthly
intervals, and that the tape heads, pressure roller and the sensing switch are cleaned
every three months with a cotton bud dampened with a proprietary tape head cleaning fluid.
New units carry a 21 month warranty from the date of manufacture as shown on the year and
month marking on the base of the machine. The year and month marking forms part of the
machine serial number as follows:-
e.g. typical example. Serial No.9IAHA16058:-
9 is the year. 9 = 1989
0 1990, 1 = 1991 etc
I is the month I = Sep, L = Dec, A = Jan etc
A is days in month. A = 1 to 10, B = 11 to 20 and C = 21 to 31
HA16058 is the machine serial number

Normal test conditions when waiting to answer. After answering the telephone and answering
machine presents a loop resistance to line of approximately 325 ohms measured at 27.5ma.
Additionally, the instrument will draw about 2.5mA on hook, this may appear to give
apparent 'Low Loop' line test conditions. With the handset off-hook, Falcon II, like many
modern telephones may give high resistance telephone loop test conditions.
This facility causes the machine to release the line when a telephone connected to the
same line is taken off-hook. This facility is inhibited for up to 4 seconds after
answering to prevent false release of the machine from line due to line 'ringing' (current
surge to & fro) when answering.
CLEAR DETECT (Line Break stop)
Modern exchanges such as System X and Y, generate a 100 ms line break on the called
parties line when the calling party clears down, this is called a disconnect clear signal.
Shorter line breaks are generated by most other exchange types. Falcon II will detect a
disconnect clear signal and immediately release the line without waiting for network
Falcon II uses two (super) capacitors instead of batteries to retain memory information.
one capacitor is charged from both the line and the plug top transformer and protects the
32 telephone number stores and the programmable features of the instrument for up to 24
hours in the event of both supplies being disconnected. The second capacitor is charged
from the plug top transformer only and will keep the clock running for 30 minutes should
the mains supply be disconnected.
In the event of a mains failure, all mains dependent facilities cease to function. If the
machine was set to answer calls before the power failed, on restoration of the mains
supply, it will reset to answer and the LCD display will show a double bar (--)
indicating the machine has reset and the Answer LED will flash if any messages have been
received, but gives no indication of how many. Messages received before the power failed
are not lost and can be played back in the normal manner.
Mains failure for periods in excess of 30 minutes -
When the mains power is restored, the clock, not displayed will reset to 12 AM Sunday and
progress on from that point. When the instrument is reset to the HOME mode, the clock
display will be seen flashing, indicating that the clock is wrong. Messages received after
a power interruption of 30 minutes or more, or if the clock is not set, i.e. clock display
flashing, will have no time recorded onto the incoming message tape, just a
"beep" between messages.
During mains supply failure, if line power is present none of the memory stores should
corrupt or clear. Power and line disconnection for periods greater than 24 hours will
reset all memory locations to their default. i.e. Answer after two rings, unlimited
recording time and security code 111. Number stores will either clear completely or set to
Note:- The above times have been obtained from workshop testing and contain a factor to
allow for the possible difference in component tolerances and deterioration due to ageing,
longer times may be experienced in practice. The manufacturers only claim 30 minutes
protection if the mains fails before all memory locations clear and make no reference to
line power retaining memory information.
OUTGOING MESSAGE TAPE 30 Seconds
If a longer OGM tape were to be provided and the user only recorded a short OGM or a
caller were to clear down early without listening to all the OGM, an unacceptably long
period would elapse before the machine resets to the answer mode after a caller has
cleared. See Reset Time below.
When the machine answers the line, it checks whether paytone is present. If paytone is
detected, the OGM is delayed for up to 15 seconds. It is also possible that mains hum on
the line can be mistaken for paytone, this too can delay the sending of the OGM. Setting
the VOX switch to Low may overcome this problem.
Falcon II provides the facility for remote interrogation using a security code programmed
into the machine by the customer from the telephone keypad.
Remote interrogation is achieved by using a BT Remote Interrogator or MF4 telephone to
enter the security code during the OGM, further instructions may then be given over line
as per the user guide.
RESET AT THE END OF A CALL
Reset using 30 second Outgoing Message Tape is typically 20 - 40 seconds.
BT only recommended and supplied 30 second OGM tapes as longer tapes would extend the
reset period to an unacceptable time.
Falcon II will seize the line after the number of ringing cadences programmed into its
memory. The ringing circuit has been designed to recognise both PSTN and all internal
ringing cadences generated by BT PABXS.
By selecting the LONG position, Falcon II will respond to PMBX ringing, i.e. continuous
ringing of > 2 seconds.
VOICE/TONE DETECTION (Voice Operated Switch - VOX)
Falcon II is able to differentiate between voice and tone signals. It is required to hold
the line to voice signals, but release the line when a network tone or silence is present
after 5 seconds.
The VOX sensitivity has a High and Low sensitivity switch provided. The normal switch
position is High. In this position it is possible that line noise may be detected as
speech. If this happens the machine will record line noise up to its maximum message
length. If line noise causes persistent problems, switch to the low position.
