Telephone Line Monitor
USER GUIDE
For Technical Assistance
Please Phone: (07) 5596 5128
DESCRIPTION
Our Telephone Line Monitor (TLM) device is designed to activate whenever
the Telephone Line that it is connected to has been disconnected or cut.
The incoming Telephone Line MUST connect to the LINE IN port of TLM.
All telephones and telephone devices MUST connect to the LINE OUT port of
TLM.
This is extremely important because Telephone Devices connected in Parallel
to the same Telephone Line as TLM will activate the TLM Relay whenever they
are used.
TLM is totally ‘Transparent’ in operation and will not affect the use of the
Telephone Line in any way.
TELEPHONE LINE DISCONNECTION
TLM’s function is to constantly monitor the Telephone Line that it is connected
to and only respond when the telephone line connected to it has been
disconnected or cut.
In the event that this happens, after 6 seconds TLM will automatically CLOSE
the contacts of an Internal Relay, which in turn can be used to trigger other
external equipment to advise of the loss of Telephone Line. The contact of the
Internal Relay will remain closed until the telephone line service has been
restored.
TLM’s Internally Relay has Dry Relay Contacts, rated at 12V/1A.
Three Optional low cost Accessories are available from Natcomm for use with
TLM, to alert the user that the Telephone Line has been lost. These Accessory
Devices are all designed for Easy User Installation. See page 5 for further details.
The Relay Output of TLM can alternatively be used to Control a 3rd Party
Electrical Device (not supplied). An Accessory Device Connection box (with 2
screw terminals) is supplied for this purpose and connects to TLM via a short
supplied cable.
Important Note : TLM waits 6 seconds before activating the internal relay,
should it detect that a telephone line connected to it has been disconnected or
cut This period is designed to overcome false alarms should a very brief
interruption to the telephone line service occur.

TELEPHONE LINE CONNECTION
1. Single Telephone Socket Operation
TLM can be connected to ANY Telephone Socket on the Telephone Line.
If another Telephone Device is to be used on the same Telephone
Socket, then it can be connected using a Double Telephone Adaptor (not
supplied) to the LINE OUTPUT Port of TLM.
2. Multiple Telephone Socket Operation
a) The LINE IN port of TLM MUST be connected to the Incoming
Telephone Line (which connects to the first socket on your line).
b) The LINE OUT port of TLM MUST be then be connected to all
Telephone sockets on the Telephone Line.
c) This installation procedure MUST be carried out by a suitably qualified
telephone technician.
d) This will ensure that there are NO Parallel connected Telephone
Devices used on the same line, which would cause TLM to respond as
if the Telephone Line was Cut or Disconnected.
POWER CONNECTION
A 12VAC Power Adaptor is supplied with TLM. It can also be operated
from a 12VDC source, with a minimum capacity of 300mA. If an
alternative 12VDC source is used, polarity is not important.
OPERATION WITH ADSL
TLM can operate on a Telephone Line which also has an ADSL service.
TLM will not affect the ADSL operation.
ADSL will not affect the operation of TLM.
If used, the ADSL FILTER should be fitted ahead of the TLM device.

INSTALLATION INSTRUCTIONS
1. Telephone Line Connection
The incoming Telephone Line MUST connect to the LINE IN port of TLM.
All telephones and telephone devices MUST connect to the LINE OUT port
of TLM.
This is extremely important because Telephone Devices connected in
Parallel to the same Telephone Line as TLM will activate the TLM Relay
whenever they are used.
2. Accessory Device Connection
(Light, Loud Siren or other device)
If you are connecting a NATCOMM Accessory, refer to pages 5-11.
If you are connecting a THIRD PARTY ELECTRICAL Accessory, refer
to pages 12 - 15.
An interface box with 2 screw terminals is supplied to provide a convenient
means of connecting your 3rd Party Electrical Device to the Relay contacts
located within TLM.
A short connection lead is also supplied to connect the connection box to

you maintain polarity of the wires.
The Red wire from the Connection Box must connect to Red wire
connected to the Strobe Accessory only.
The Black/Red wire (Red wire with Black stripe) from the Connection Box
must connect to Black wire connected to the Strobe Accessory only.
Polarity is important. Failure to maintain polarity
will cause fatal damage to the Strobe Accessory.

POWER CONTROL UNIT
AS/NZS3260 Approval Number Q00217
Our POWER CONTROL UNIT (PCU-2) accessory will allow you to use
a 120VAC to 240VAC Electrical Device ( such as a Light, Horn or a Loud
Siren) to INDICATE when your telephone line is Cut or Disconnected.
It is designed for quick and easy USER INSTALLATION.
It has a standard AC Male Power Plug connected to a short cable. This
AC Male Power Plug should connect to a Wall Power Socket.
It also has a standard AC Female Power Socket connected to a short
cable. This AC Female Power Socket should connect to the AC Male
Power Plug of your Electrical Device.
Your can connect TWO or more devices to POWER CONTROL UNIT if
required. It is designed to operate up to 10Amps in total.
A short cable with RJ 4 pin connectors is supplied with your POWER
CONTROL UNIT. One end of this cable plugs into POWER CONTROL
UNIT and the other end plugs into the RELAY OUTPUT port of your TLM.
Our Alternative Model PCU2 is set up in a NORMALLY OFF configuration,
which means that the electrical equipment connected to this device will
be SWITCHED OFF at all times, until your TLM provides a relay closure.
TLM will then provide the relay closure whenever the telephone line is
Cut or Disconnected.

UNPOWERED 3RD PARTY
DEVICE CONNECTION
The relay output from TLM can also be used to advise an external 3rd
party electrical device that the telephone line has been cut or
disconnected.
The relay output from TLM is Dry Contact (Rated at 1A at 12V).
TLM’s relay contacts connect to the centre 2 pins of the 4P4C RJ
socket of TLM.
This output is ideal for many devices where a simple ‘unpowered’
relay closure is required.
A Connection Box with a short cable to connect it to TLM is provided
to allow for quick and easy connection to the external 3rd part device.
The Connection Box has 2 screw terminals for cable connection to the
external 3rd part device.
The Connection Box screw terminals also connect to the centre 2
pins of the 4P4C RJ socket of TLM.
See the diagram on page 12 for further detail.
If your 3rd party electrical device requires powered output from the
TLM relay contacts, please refer to pages 14-15.
Important Note : The Dry Contact Relay within TLM is rated at
12V and 1Amp. If you exceed either of these parameters,
permanent damage will result.

DEVICE CONNECTION
The relay output from TLM can also be used to advise an external 3rd
party electrical device that the telephone line has been cut or
disconnected.
The relay output from TLM is Dry Contact (Rated at 1A at 12V).
You can connect a power source AC or DC up to 12V and 1Amp to the
relay contacts if required.
In this situation 1 leg of the wires connecting to the TLM relay should
come from an external power source (not supplied).
A Connection Box with a short cable to connect it to TLM is provided
to allow for quick and easy connection of this power source.
The Connection Box screw terminals will then connect the power
source to one of the centre 2 pins of the 4P4C RJ socket of TLM.
When the TLM relay closes, power will then output through the other
centre pin of the 4P4C RJ socket of TLM to the remote electrical
device.
When the relay opens, this power flow will be removed.
See the diagram on page 14 for further detail.
Important Notes :
1) The Dry Contact Relay within TLM is rated at 12V and 1Amp.
If you exceed either of these parameters, permanent damage
will result.
2) Do NOT use the 12V power adaptor supplied with TLM as a
power source for the connection box or 3rd part accessory.
Doing so can cause TLM to not function correctly due to power
‘brown out’.
