TELEPHONE LINE MONITOR

 

 


Will warn you if your Telephone Line is Cut or Disconnected

 

Details

  • Our Telephone Line Monitor (TLM) is designed to let you know when your Telephone Line has been cut or disconnected by closing an Internal Relay. The Relay will open whenever the Telephone Line is present.

  • The internal relay is designed to directly control a choice of Strobe light, Siren or our Power Control Unit accessories (see below).

  • The dry contact relay output from TLM can also control any 3rd Party Electrical Device that accepts a relay input.

 

Operation

 

TLM constantly monitors the Telephone Line that it is connected to warn if the Telephone Line has been Disconnected or Cut for a period of 6 seconds or longer.

In the event that this happens, 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 below 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.LINE VOLTAGE of the attached telephone line.

 

Installation

TLM has 4 ports :

1) The incoming telephone line should be connected to the TELEPHONE LINE IN port of TLM

2) The TELEPHONE LINE OUT port of TLM should connect to all of your telephone devices or telephone extensions.

3) Your Natcomm Accessory or 3rd Party Electrical Device should connect to the RELAY OUTPUT port of TLM. A plug in 'Connection Box' with Screw Terminals is supplied with TLM to provide for easy connection to your Accessory Device. 

4) The supplied 12V Power Adaptor should be connected to the 12V Power port of TLM. A 12VAC or 12VDC input can be used.

 

Accessories

SIREN

An optional SIREN accessory is available with TLM. The siren connects direct to TLM and does not need any external power.

The SIREN accessory outputs up to 110dB and is therefore suitable for small factories. A volume adjustment knob allows for the ideal volume to be set for individual environments.

The SIREN accessory with volume adjustment sells for $A 69.00 incl GST.

 

STROBE

An optional BLUE STROBE LIGHT accessory is available with TLM. The STROBE LIGHT accessory connects direct to TLM and does not need any external power.

It uses 6 high brightness LEDs to provide a subtle but effective FLASHING BLUE LIGHT indication that the telephone line has been cut or disconnected. It can be wall or ceiling mounted using the supplied screws or double sided tape. Flash rate: 60-90 per minute.

A 10 meter cable is supplied with the Strobe Light to allow it to be located remote from TLM. The cable can be easily shortened or extended if required.

The STROBE LIGHT accessory sells for $A 49.00 incl GST.

 

 

POWER CONTROL UNIT

The optional Power Control Unit (PCU) will allow you to connect an Electrical Device such as a Light, Horn, Speaker etc, which connect to the normal 240V Electricity Supply.

PCU is designed for quick and easy 'plug in' user installation. Simply connect the POWER PLUG of the PCU to your electricity supply and the POWER SOCKET to your electrical equipment. The PCU then connects direct to TLM with a supplied cable.

PCU is available in two models.

  • Model PCU -1 is configured in a NORMALLY ON configuration, so that your equipment will be switched ON, unless commanded by the TLM device.
  • Model PCU -2 is configured in a NORMALLY OFF configuration, so that your equipment will be switched OFF, unless commanded by the TLM device.
  • Model PCU -2 should be used with TLM.

The 240V POWER CONTROL UNIT accessory sells for $A 99.00 incl GST.

 

 

3RD PARTY ELECTRICAL DEVICE

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.
