PRODUCT DESCRIPTION
Our intelligent and programmable Lock Control unit (LCU) is designed to
provide for Telephone Line based DTMF controlled switching of 1 or 2 internal
Dry Relay Contacts, which can be used to control 1 or more external devices.
They are ideal for applications such as Basic Access Control, Lift Control or
the Powering ON, OFF or RESET of One or More Electrical devices.
Model LCU1 - provides for control of 1 Dry Relay contact
Model LCU2 - provides for independent control of 2 Dry Relay contacts
Model LCU3 - provides Auto Answer operation with 2 Dry Relay contacts
The Relay Contacts are rated for 12volts, 1amp.
Our LCU units connect (in Parallel) to ANY Telephone Line and listen and
respond to programmed DTMF Touch Tone commands.
Each LCU has One (LCU1) or Two (LCU2) Dry Relay contacts that can be
independently controlled by DTMF Touch Tone commands from an Incoming
Telephone Call OR they can respond to Any Parallel telephone device
connected to the same line.
Model LCU3 also has Two Dry Relay contacts and this Model can be set to
Answer Incoming calls after a User Programmable number of rings (See page
5 for more details on LCU3).
One or More LCU units can be fitted to the same telephone line to provide
a simple and flexible Access Control or Power Control solution.
Each LCU Relay can be programmed with its own unique DTMF code (from
1-4 digits) and whenever the correct code is entered from Any telephone on
that line, or from an Incoming Telephone Call, the appropriate Relay will close
for a User Programmable period of time (programmable from 1-99 seconds).
LCU units connect to ANY telephone socket on a telephone line. Multiple
units can connect to the same socket, or they can be connected to different
sockets on the same line.
LCU is supplied with a 12VAC power adaptor. 12VDC can alternatively
be used to power LCU if required (min of 200mA).

PRODUCT DESCRIPTION
LCU is designed to connect in PARALLEL to a telephone line. It has a single
RJ11 (6 pin) Telephone Line input port.
Model LCU1 provides One 4 pin RJ port to connect to the internal relay.
Models LCU2 and LCU3 provides Two 4 pin RJ ports to connect to the internal
relays.
Connection Box(s) are supplied with short leads for easy connection to LCU.
Each Connection Box has 2 Screw Terminals to provide for connection of
your electrical equipment to the Internal Relays of LCU.
Once installed, LCU will automatically respond to any 1,2,3 or 4 digit DTMF
code that is programmed by the user. LCU responds to all DTMF commands,
ie: 0-9,*,#,A,B,C &D.
The closure time of the relay can also be set by the user for periods of 01
to 99 seconds. If a setting of 00 is entered, LCU will provide latching of the
relay on a toggle basis, so that equipment (such as a 12V light, Video
equipment etc) can be switched ON or OFF as required.
LCU can also be set to respond to DMTF commands from Incoming calls
only, or Incoming and Outgoing calls (default setting).
LCU's can also be programmed to respond to a set code within a dialed
sequence.
For example, a Door Phone could call a specific business within a Multi
Tenanted Office Building. The operator after answering could then Dial
123456 and then hang up.
One LCU relay set to respond to 12 could open the front door for 15 seconds.
A second LCU relay set to respond to 34 could alert the Elevators to allow
access to Floor 3. A third LCU relay set to respond to 56 could release the
Door Strike which allows access to offices on Floor 3.
LCU is provided with a Two Year Factory Warranty.

PRODUCT DESCRIPTION LCU3
LCU3 provides all of the features described on pages 3-4. Please read these
pages first.
Model LCU3 has the additional ability of being able to Answer an Incoming
call on a telephone line, after a user selectable number of rings (0-20 rings).
Setting 0 Rings, disable the Auto Answer facility.
The Default setting is that LCU3 will Answer incoming calls after 2 rings.
After Answering a telephone call, LCU3 will ‘listen’ for DTMF Commands. If
a programmed command is detected, LCU3 will close one or both of its
Internal relays, depending on User Programming, exactly the same as LCU1
and LCU2.
Our LCU1 and LCU2 models do not answer calls. They respond to DTMF
commands made during an outgoing call, or an incoming call answered by
another device on the line, such as LCU3, Answering Machine or other
suitable answering device.
Multiple LCU1 and LCU2 units can be used with LCU3 to provide for Basic
Access Control, Lift Control or the Powering ON, OFF or RESET of One or
More Electrical devices.
ADDITIONAL LCU3 PROGRAMMING FEATURES
1. LCU3 can be programmed by simply calling in to it. When it answers, press
### to enter programming mode. Note it cannot be programmed if the Auto
Answer facility is disabled.
2. LCU3 can have all of its program setting returned to default, by dialling into it,
entering ### (to enter program mode) and after hearing the confirmation ‘beep’,
pressing 13579.
3.LCU3 has an additional MAXIMUM CALL TIME Programming feature which
must be set during the programming procedure.This is the amount of time that
LCU3 will hold a call waiting for commands after answering. The default setting
is 20 seconds, which is the minimum setting. This can be increased up to 99
seconds if required. See pages 14-15 for full programming details.

PRESS ### within 30 SECONDS.
3) You will hear 3 short ‘beeps’ to confirm you are in programming
mode.
4) Individual Parameter Programming Entries are carried out by
pressing further keys on the attached telephone.
5) Your unit will generate 1 short ‘beep’ to confirm acceptance of
command.
6) Your unit will generate 1 long ‘beep’ to advise of an entry error.
7) If 1 long ‘beep’ is detected, your command should be repeated.
8) You can Program Lock 1 or Lock 2 (model LCU2 and LCU3
only) individually by pressing :
Press #1 for setting Lock 1 parameters
Press #2 for setting Lock 2 parameters
LCU3 PROGRAMMING
