Installing the FIT-80
Follow all appropriate electrical codes and use only approved electrical
fittings for the installation.
For waterproofing purposes apply Teflon tape to all glands and conduits.
Choose a wall location that is free of obstructions and permits space for ½”
NPT conduit runs.
See:Figure 2 -
Dimensions.
Ensure mounting can support 16 lbs (7.3 kg) and any additional load to
which the telephone may be subjected.
Ensure that none of the electrical connection circuits are live.
Separate the faceplate from the housing by removing the two temporary,
factory installed screws and unplugging the wiring harness from the
faceplate.
To change the Tone/Pulse setting to pulse, if required:
oMove the jumper from pins 1 & 2 of the Tone/Pulse connector to
pins 2 & 3.
Tip: The FIT-80 is
factory preset for DTMF
tone.
oTo change the setting back to tone move the jumper back to pins
1 & 2.
Drill or punch cable entrances as required at the three drill dimples.
Use the template provided or the enclosure itself to locate and drill holes for
mounting screws.
Secure the unit to the wall.
Tip: Use ¼” or M8
screws to secure the unit
to the wall.
See: Figure 3 - Electrical
Connections
Bring cable into the enclosure through the conduit entrance and attach
individual wires from the exchange (Tip/Ring/Ground) to the surge arrestor,
(Tip & Ring are not polarity sensitive.). If a conduit hub is used, ensure it is
grounded to the ground stud.
Plug the wiring harness back into the faceplate and secure the faceplate
with the twelve screws provided.
Note: If Vandal
Resistant screws were
ordered a special driver
bit will also be included.
Connect the telephone lines at the local exchange or demarcation block.
Test the unit by making calls to and from another station.
Operation
Once your Model FIT-80 Telephone has been properly installed and
energized, operation is identical to most other single line telephones.

Field Repairs
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
before attempting to replace the fuse.
Carefully remove the front cover assembly and separate from the housing
by disconnecting the harness plugs. NOTE that the handset and all
electronics are attached to the front plate.
See: Figure 3 - Electrical
Connections
Perform the necessary repairs or adjustments.
Carefully replace the front plate and install all twelve 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 pulling on the ends of the fuse holder 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.
Changing the Tone/Pulse Setting
Set the Tone/Pulse jumper for the desired operation. For pulse, set the
jumper between the center pin and the “P”, for tone set it between the
center pin and “T”.
See: Figure 3 - Electrical
Connections
Cleaning Tips for Guardian Telephones
Guardian Telephones may occasionally need to be cleaned to maintain appearance. Generally, wiping
the surface with a clean, water dampened cloth will remove most films or residues. If the soiling is too
stubborn for plain water, a mild detergent solution may be used. Be sure to wipe away any detergent
residue with a plain water dampened cloth. The Telephone may be cleaned with any general-purpose
household glass and surface type cleaner. Do not spray the telephone directly! Spray the cleaner on a
soft cloth then wipe the surface. Pre-treated cloths, like those used for eyeglasses or cameras, may be
used to clean the Telephone. Premoistened towelettes may also be used, however, avoid those
containing lanolin or aloe as they will leave a slippery residue. The handset and surface of the telephone
may be cleaned with disinfectants used for general cleaning in a medical environment. Isopropyl alcohol
may be used applied with a cloth. Avoid using alcohol on silicon based keypads, since doing so may
significantly degrade legibility.
Do not use furniture polishes, waxes or plasticizer-based cleaner (Armor All etc.)
Do not use lanolin, aloe, glycerin or other skin care type products.
Do not apply any solvent such as acetone, mineral spirits etc.
Do not directly spray or immerse the handset.

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 source.
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 Guardian Telecom to obtain authorization to
return the product. This can be done by done by completing a RMA form online at
www.guardiantelecom.com, or by calling the service telephone number given in
this manual.
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.
(Where a product is being returled for repair from outside of Canada, customs
documentation must show the product’s serial number, date of export [date of
purchase], and a notation that the equipment is: “Canadian goods returning.”)
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 by the factory.
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 product returned, generally within five working days.
