Model WRT-A

Installing the WRT-A

• WRT-A telephones shall be installed by qualified service personnel.

• The WRT-A is set to tone dialing when shipped. If pulse dialing is required

see the section on Setting Dialing Mode.

• Follow all appropriate electrical codes and use only approved electrical fittings for the installation.

• Choose a wall location that is free of obstructions and permits space for wiring.

• Ensure mounting can support 6.5 lbs (2.95 kg) plus any additional, foreseeable load.

• Ensure that none of the electrical connection circuits are live.

Mounting

• Use the template or the unit itself to locate and drill holes for mounting screws.

• Secure the unit to the wall.

Hard Wiring the WRT-A to the Telephone System

• Remove the wiring access cover plate.

• Install a suitable conduit hub or cable gland in the cable entrance hole.

• Bring cable into the enclosure through the cable entrance and attach

individual wires from the exchange – Tip/Ring/Ground – to the surge arrestor (Tip & Ring are not polarity sensitive).

WARNING

Protective earthing terminal of the phone shall be properly hardwired

• Replace the wiring access cover plate.

Final Check

• Check the set visually for loose screws and trapped wires. Check that the handset hangs freely in the cradle and that the handset cord is not trapped by the door.

• Check that the faceplate is snug to its gasket, paying particular attention to the area around the cradle. Check that the door closes flush to the housing.

• Test the unit by calling to and from another unit on the exchange.

to a protective earth system.

See: Figure 3 - Setting

Dialing Mode & Installation

See: Figure 2 - Overall Dimensions

Operation

• Once your Model WRT-A Telephone has been properly installed and energized, operation is identical to most other single line telephones.

WARNING

Due to magnetic fields, it is possible that dangerous objects may get trapped within the earcap region of this device.

Setting Dialing Mode

The WRT-A is shipped from the factory set for DTMF (Tone) dialing mode. If loop disconnect (Pulse) dialing is required proceed as follows.

• Loosen the five captive screws in the faceplate and swing the faceplate to the left. If the set is on a vertical surface the faceplate will stay open like a book in this position. Take care not to disturb the internal wiring.

• Change the position of the Tone/Pulse jumper on the circuit board to Pulse, as indicated on the label.

• The set will now be in pulse dialing mode, it can be returned to tone mode by changing the position of the jumper back to the Tone position.

• Carefully replace the front plate and install all five screws. Do not over tighten the cover screws, there is a flexible gasket between the cover and the body. Excessive tightening of the screws deforms the gasket and reduces the weather resistance of the set.

Field Repairs & Adjustments

Field repairs may only be carried out by qualified technicians using OEM parts. Substitution of parts voids warranty and may pose a hazard to users of the equipment.

See: Replacement Parts

• Disconnect the telephone from Tip and Ring power supplied by the PABX or central office before attempting repairs.

• Perform the necessary repairs or adjustments.

• Carefully replace the front plate and install all five screws. Do not over

tighten the cover screws, there is a flexible gasket between the cover and the body. Excessive tightening of the screws deforms the gasket and reduces the weather resistance of the set.

Fuse Replacement

• Remove the old fuse by pushing in the end cap of the fuse holder and turning counterclockwise to open. Insert a new 0.25 amp, 250Volt, 3AG fast blow fuse and close the fuse holder.

WARNING!

• Replace only with a 0.25 amp 250V 3AG fast blow fuse. Failure to do so will void the warranty.

• If, on reconnecting power, the fuse fails, check the telephone system wiring. The fuse protects the Tip and Ring line from the telephone system. It is usually powered at 48 volts DC and must not be connected to 120 volts AC.

See: Figure 4 - Fuse Replacement

Note: Ensure that connections are secure before replacing faceplate.

Government Certification

Attached to the telephone is a label for the Australian Communications Authority. This identifies equipment certifications indicating the WRT-A series telephones meet certain telecommunications network protective, operational and safety requirements. This agency does not guarantee the equipment will operate to the user's satisfaction.

Before installing this telephone equipment, users should ensure it is permissible to connect the equipment to facilities of the local telecommunications company.

Equipment must be installed using acceptable connection methods. In some cases, the telephone users inside wiring, associated with a single line service, may be extended by a certified connector assembly (telephone extension cord). The customer should be aware that in some situations compliance with the above conditions may not prevent degradation of service.

Repairs to certified equipment should be made by a supplier designated authorized maintenance facility.

For their own protection users should ensure the electrical ground connections of the power utility, telephone lines and internal metallic water pipe systems, if present, are connected. This precaution may be particularly important in rural areas.

CAUTION: Users should not attempt to make ground connections, but should contact the appropriate electrical inspection authority or electrician.

Notification to Telephone Company

Upon request, the customer must notify the telephone company of the particular line to which the connection will be made and provide the Australian Communications Authority registration number. The local telephone company may request disconnection of the telephone where alterations or malfunctions affect the telephone’s performance.

ACA Rules and Ringer Equivalence Number

This equipment complies with the regulation AS/ACIF S002:2001 Australian Standard Analogue internetworking and non-interference requirements for customer equipment for connection to public switched telephone networks. On the side of this equipment is a label that contains, among other information, the ACA registration number and ringer equivalence number (REN) for this equipment. If requested, this information must be provided to the telephone company.

The REN is used to determine the quantity of devices which may be connected to the telephone line. Excessive RENs on the telephone line may result in the devices not ringing in response to an incoming call. In most, but not all areas, the sum of the RENs should not exceed three. To be certain of the number of devices that may be connected to the line, as determined by the total RENs, contact the telephone company to determine the maximum REN for the calling area.

Service changes and Limitations

The telephone company may make changes in its facilities, equipment, operations, or procedures that could affect the operation of the equipment. If this happens, the telephone company will provide advance notice in order for you to make the necessary modifications in order to maintain uninterrupted service.

This equipment can not be used on public coin telephone service as provided by your telephone company. Connection to party line service is subject to state tariffs (contact the state public utility commission, public service commission or corporate commission for information.)

Guardian Product Return

Guardian products have been quality tested and are in full working order when shipped from the factory, given the rugged nature of these products shipping is not expected to damage a unit. In the unlikely event of a malfunction, Guardian follows the three step procedure below.

Step I - On-Site Correction

• The most common source of difficulties with a new product is improper installation in one of

two ways: incorrect wiring connections or connection to an incorrect power sou r ce.

• Product wiring needs to be properly connected to the on-site wiring . Correct wiring

instructions are shown in the user manual included with the product.

• Connecting a telephone to a standard power source, rather than tip & ring, will blow the

telephone’s internal, user-replaceable fuse. In the event of fuse burn-out, disconnect the telephone from the power source, replace the fuse, and reconnect following the wiring diagrams provided with the product.

Step II - Return Materials Authorization (RMA)

• When a product has been installed following user manual instructions, and the unit fails to

operate, the user must contact the Service Number indicated on the previous page, to obtain authorization to return the product.

• After providing information on the product, the owner and the nature of the problem,

Guardian will issue a RMA number, to be shown on documentation returned with the product.

• In addition to the RMA number, shipping documents should include name, address and

telephone number of the owner along with contact information for the person responsible for the repair and/or the user who identified the malfunction.

Step III - Factory Authorized Service

• Once received, each product is carefully inspected and tested. If the product is under

warranty, repairs are completed and the product returned to the owner, generally within five working days of receipt.

• A product that has been subjected to misuse, neglect or accident or is beyond the warranty

period will be evaluated. The service department will provide the owner’s representative with a repair cost estimate. Once approved, repairs are completed and the prod uct returned, generally within five working days.
