SYSTEM INTRODUCTION
This kit will enable a caller at an entrance point to signal an occupant in the dwelling by
pressing a call button which will send an electronic call tone to an audio telephone. A
Yellow ‘SPEAK’ LED will indicate the call has been answered and a two way conversation
can take place, the occupant can release an electric lock release by pressing a button on
the telephone base unit. The kit does not include the electric lock release. A 12V AC
release should be used with this kit (The output for the lock is a dry contact relay so any
other type of lock can be used with an appropriate PSU). If this kit is to be used with a
gate, the dry contact output can be used to trigger the gate control board. DDA features
such as a ‘SPEAK’ LED, ‘DOOR OPEN’ LED and reassurance tones are standard on this
kit.
A two code, two relay codelock unit is also incorporated into the door panel to allow users
to gain access using an access code.
SYSTEM COMPONENTS
This kit comprises of a flush or surface vandal resistant door panel, audio telephone and
PSU. Up to a maximum of three telephones can be used on the system to call in parallel.
DOOR PANEL
The vandal resistant door panel will consist of an amplifier module, codelock module,
button, vandal resistant plate, frame and back box.

Maximum acceptable resistance for above cables = 3Ω
TESTING THE INSTALLATION
- Check all the connections have been made correctly and dip-switches have been set
and then power up the system.
- Call the apartments. Check for call to the apartment, speech in both directions and lock
release and correct operation of the SPEAK & DOOR OPEN LED’s.
- If the volume of speech needs to be adjusted, this can be done by adjusting the presets
on the rear of the amplifier at the door panel.
- Program a code into the codelock and check it releases the door for the programmed
time.
PANEL CARE
The door panel is manufactured from 12 Gauge 304 grade stainless steel. It is important
that the facia is cleaned on regular occasions to prevent dirt build up and tarnishing of the
metal. A general household metal polish can be used but care should be taken to follow
the grain of the metal when polishing and also avoid any polish build up around the call
button which may prevent the button from operating correctly.
ACCESSORIES CONNECTION GUIDE

VR4KCLM-1 CODELOCK
The VR4KCLM-1 includes two relays (5A contacts), two push to exit inputs (Switched
negative) and can have up to two 4 to 8 digit access codes programmed (One per relay).
The relay times can be programmed from 01 second up to 99 seconds or by setting the
relay time to 00, latch the relay (To latch, enter the code followed by enter and to unlatch
enter the code followed by clear).
INITIAL PROGRAMMING
All programming is carried out using the codelock keypad. The programming menu is
protected by an engineer’s code. The factory default engineers code is 111111 (6x1). This
code can be changed to any four to eight digit code during the program but must be
different to the codes used to gain entry. Follow the flow chart to setup the system:-
Enter the engineer’s
code.
111111
Then press enter
The red LED will illuminate to acknowledge programming mode. If the red
LED does not illuminate check the master code is correct. If the master
code may have been changed from the factory default and you do not
know what it is then follow the factory default procedure on the following
page.
Enter a new engineers
code or enter the same
engineers code again
followed b
y
enter
This code can be from 4 – 8 digits and will not activate a relay. It can only
be used to enter programming mode.
Note this new code in the box provided on the next page. It will be needed
to re-program the codes in the future.
Enter the access code
for relay 1 and then
press enter
This code will be used to open the door/gate (Relay 1). The code can be
from 4 – 8 digits long and must be different from the engineer’s code.
Enter a two digit relay 1
time from 00 – 99 and
then
p
ress enter
This is the time the relay 1 will energise for. 00 will latch the relay when
the code is entered and require the code followed by clear to unlatch.
Enter the access code
for relay 2 and then
press enter
This code will be used to open the door/gate (Relay 2). The code can be
from 4 – 8 digits long and must be different from the engineer’s code.
Enter a two digit relay 2
time from 00 – 99 and
then
p
ress enter
This is the time the relay 2 will energise for. 00 will latch the relay when
the code is entered and require the code followed by clear to unlatch.

TROUBLE SHOOTING
SYMPTOM TEST
No speech from the door panel to the
telephone.
Check terminal 2 on the amplifier for continuity to
terminal 2 on the telephone.
Check the voltage drops to approx. 1Vdc after the
handset is lifted. (If not try another telephone)
If all else fails try another amplifier at the door station
No speech from the telephone to the door
panel.
Check terminal 1 on the door panel amplifier for
continuity back to terminal 1 on the telephone.
Check the voltage drops to approx. 4Vdc after the
handset is lifted. (If not try another telephone)
If all else fails try another amplifier at the door station
No speech in either direction Check the 315mA fuse in the power supply
Check for 12Vdc across terminals + & - on the door
panel amplifier. This should be there all the time and
comes directly from the PSU.
Lock will not operate from telephone Check terminal 5 on the telephone. This terminal
shorts to terminal 3 of the telephone when pressed
(Becomes 0V) and sends a 0V to terminal 5 on the
VX136 amplifier at the door panel which in turn
triggers the relay
Check the relay on the VX136 is energising. Use a
continuity meter to check the switching.
Nothing happens when call button is
pressed
Check the common of the button is connected to T
on the VX136
Check continuity from the other side of the call
button to terminal 4 on the handset
Hum on the speech lines Ensure all intercom cables do not run close to higher
voltage cables
Try another amplifier at the door panel.
Codelock not operating Check power on terminals 1 & 2 on the codelock is
12V. If this voltage is lower it may not operate the
relays correctly.
Check the keys beep when pressed. This will not
happen if the codelock is faulty or has the incorrect
power connected to terminals 1 & 2
Try re-programming the codelock
