TELEPHONELINECONNECTION
1. Single Telephone Socket Operation
TLMcanbeconnectedtoANYTelephoneSocketontheTelephoneLine.
If another Telephone Device is to be used on the same Telephone
Socket,thenitcanbeconnectedusingaDoubleTelephoneAdaptor(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
Telephonesockets onthe TelephoneLine.
c)ThisinstallationprocedureMUSTbecarriedoutbyasuitablyqualified
telephonetechnician.
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.
POWERCONNECTION
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.
OPERATIONWITHADSL
TLM canoperateonaTelephoneLinewhichalsohasanADSLservice.
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
Theincoming TelephoneLine MUSTconnect tothe LINEIN portof TLM.
AlltelephonesandtelephonedevicesMUSTconnecttotheLINEOUTport
ofTLM.
This is extremely important because Telephone Devices connected in
Parallel to the same Telephone Line as TLM will activate the TLM Relay
whenevertheyareused.
2. Accessory Device Connection
(Light, Loud Siren or other device)
If you are connecting a NATCOMM Accessory, refer to pages 5-11.
IfyouareconnectingaTHIRDPARTYELECTRICALAccessory, refer
to pages 12 - 15.
Aninterfacebox with2 screwterminalsis suppliedto provideaconvenient
meansofconnectingyour3rdPartyElectricalDevicetotheRelaycontacts
located within TLM.
A short connection lead is also supplied to connect the connection box to
TLM.
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.
3. Power Adaptor Connection
CONNECT the supplied 12VAC Power Supply (or alternative 12V source)
and switch it ON.

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.

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.

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’.
