PRODUCT DESCRIPTION
Our intelligent and programmable Lock Control unit (LCU) is designed to
provideforTelephoneLinebasedDTMFcontrolledswitchingof1 or2internal
DryRelayContacts,whichcanbeusedtocontrol1ormoreexternaldevices.
TheyareidealforapplicationssuchasBasicAccessControl,LiftControlor
the Powering ON, OFF or RESET of One or More Electrical devices.
Model LCU1 - provides for control of 1 Dry Relay contact
ModelLCU2-providesforindependentcontrolof2DryRelaycontacts
Model LCU3 - provides Auto Answer operation with 2 Dry Relay contacts
TheRelayContactsarerated for 12volts, 1amp.
Our LCU units connect (in Parallel) to ANY Telephone Line and listen and
respondtoprogrammedDTMFTouchTonecommands.
EachLCUhasOne (LCU1)orTwo(LCU2)DryRelaycontacts thatcan be
independentlycontrolledbyDTMFTouchTonecommandsfromanIncoming
Telephone Call OR they can respond to Any Parallel telephone device
connected to the same line.
ModelLCU3also hasTwoDryRelay contactsandthisModelcan besetto

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.
LCUcanalsobesettorespondtoDMTFcommandsfromIncomingcalls
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
123456andthenhangup.

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.
LCUisprovidedwith aTwoYearFactory Warranty.

PROGRAMMING NOTES
LCU is programmed via DTMF commands entered from any telephone
connected to the same line.
You can only program LCU by entering ### during the first 30 seconds
after power is connected to the unit.
The following notes provide important information about the programming
procedure :
1) To enter PROGRAMMING MODE you must turn OFF POWER
to your unit and then switch POWER ON AGAIN.
2) UsingANY TELEPHONE connected to the TELEPHONE LINE,
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
LCU3 is programmed by calling in to it. When it answers, press
### to enter programming mode. Note it cannot be programmed if

PROGRAMMING OPTIONS ALL
LCU has internal flash memory which will retain your settings even if
power is disconnected. The following settings are provided :
1. SETTING DTMF RELAY CONTROL CODE
A 1 to 4 digit DTMF CONTROL CODE can be set to trigger the LCU
relay response. Model LCU2 and LCU3 provides for 2 relay output.
Each relay must use a separate Control Code.
Allowable Range : 1,2,3 or 4 digits
Default Setting Lock 1 is : *3
Default Setting Lock 2 is : *4
2. RELAY CLOSURE TIME
Upon detection of the correct DTMF Relay Control Code, LCU can
close for a period up to 99 seconds.
Allowable Range : 01 – 99 seconds
Default Setting is : 5 seconds
Model LCU2 and LCU3 provides for 2 relay output. Each relay can
have different closure times, or the same closure time.
3. INCOMING CALL and OUTGOING CALL operation
LCU is set by default to respond to DTMF commands from both
incoming calls and outgoing calls. You can also restrict it to respond
to incoming calls only.
Respond to : Incoming calls only OR Incoming and Outgoing calls
Default Setting is : Respond to Incoming and Outgoing calls
4. RESPOND TO PROGRAMMED DIGITS IN A SEQUENCE
LCU will normally only respond to the set DTMF Control Code
providing there are no other DTMF digits before or after it, within 3
seconds. It can however be set to respond to the exact set number
when there are other DTMF digits before or after it.
Default Setting is : Respond only when there are no digits
before or after the set code.

PROGRAMMING OPTIONS LCU3
LCU3 has the following additional Program capability :
LCU3 can ALSO be programmed by simply calling in to it OR it can
also be programmed in exactly the same manner as LCU1 and LCU2
with a telephone connected in parallel on the same line.
LCU3 has the following additional Program settings :
5. SETTING MAXIMUM AUTO ANSWER CALL TIME
This is the amount of time that LCU3 will hold a call waiting for
commands after answering. The default setting is 20 seconds, which
