Overview
Page/Talk Modules
Guardian's Page/Talk Systems provide reliable and easy to use paging and
communication within industrial environments such as plants, mines, mills
and factories. Individuals can be paged from any station and two or more
persons can communicate on any available line.
The Modules described in this manual are designed for use in harsh,
industrial environments and are identical for single talk line or five talk line
configurations. Modules are available with handsets, connectors for
headsets and as standalone amplifiers. Each Module provides up to twelve
watts of paging power for an external loudspeaker. A page button on the
handset of models with a handset enables one-hand paging operation.
Modules are available for indoor or outdoor use. They may be used along
with appropriate enclosures as a complete station or they may replace
modules in existing stations, either as an upgrade or to replace a
malfunctioning unit. Features of models vary according to their purpose,
however all modules have the same profile and electronic circuitry, and will
fit into any enclosure. For example amplifier modules do not have a
handset. Some models do not have an ambient noise sensor on the
faceplate; these are intended for outdoor use where the door of the
enclosure would prevent the sensor from picking up the ambient noise and
for other applications where an ambient noise sensor is not required. The
models that do have ambient noise sensors on the faceplate can replace
any other module either on a temporary or permanent basis. This is a great
convenience and cost saving feature, since only one spare module needs to
be stocked and a serviceman only has to carry around one module when
testing a system.Modules are secured with four screws for ease of
replacement.
If a PTR (Handset Module) is installed in an indoor housing as a Desk Set
Amplifier the Desk Set and the Wall Station can, at the same time be used
independently of each other. The two can be separated by up to fifty feet.
This feature can save the cost of a complete indoor station if circumstances
permit.
The modular design of the system offers great flexibility in the ways that
components can be combined. For a description of the various
configurations available see Page/Talk Replacement Modules.
In order to avoid acoustical feedback from a loudspeaker receiving a signal
from the station, a jumper on the main circuit board of every station provides
for the associated speaker to be muted when the Page button is pressed.
Group muting is also available for the same purpose. This feature mutes
adjoining speakers when the page button on any station in the group is
pressed.
Guardian's modules, stations and related equipment are compatible with
systems provided by most other manufacturers.

Note: Some models of Guardian modules include an ambient noise sensor on the faceplate that
controls the output of the associated loudspeaker. Other models do not have an ambient noise
sensor on the faceplate and can be used without the capability of adjusting the loudspeaker
output, or in the case of outdoor stations an ambient noise sensor may be installed in the
enclosure and connected to the circuit board with a harness. Features are included only if they
are specifically mentioned in the description.
Products with descriptions beginning with PT are for Guardian Page/Talk systems; those
beginning with PP are for Gaitronics Page/Party®systems. PT modules can be converted to PP
with the addition of kit P/N P5541 or kit P/N P5542.

Ambient Noise Level Adjustment
The Ambient Noise Sensor on Guardian's Page/Talk stations automatically
adjusts the volume of the associated loudspeaker up to 10dB, so that pages
can be heard over the background noise.
There are two controls on the circuit board to adjust the Ambient Noise
Sensor mechanism. The Paging Speaker Volume Control – which is
accessible either from the faceplate or from the back of the module – sets
the volume of the speaker to a comfortable level when the ambient noise is
at a minimum. The Ambient Noise Monitor Adjustment Control determines
how the speaker volume tracks the ambient noise. That is if the speaker is
not loud enough with a high ambient noise the control can be adjusted to
increase the volume. Alternatively if the speaker is too loud with a high
ambient noise the control can be adjusted to decrease the volume. It is
usually not necessary to change the setting of the Ambient Noise Monitor
Adjustment Control since it is set at the factory for average conditions.
Adjustment could be necessary if for some reason the Ambient Noise Sensor
Microphone is shielded from the source of ambient noise or some similar
situation exists.
See: Figure 10 -
Adjustments

Guardian Telecom Installation and Operation

Page 14
Group Muting
In order to avoid acoustical feedback it may be desirable in certain
circumstances to mute speakers associated with adjoining stations when
making a paging call. This can be accomplished by interconnecting the “Group
Mute” terminals of each station in the group, and setting the speaker mute
jumpers on the circuit boards to the appropriate position.
See: Figure 9 - Electrical
Connections and
Figure 10 - Adjustments
Note: Putting the mute jumper of a station in the on position will mute the
associated speaker when the page button is pressed. If the jumper is in
the off position the speaker will not be muted when the page button is
pressed.
If group muting is used the associated speaker of any station in the group with
its mute jumper in the on position will be muted when a paging call is made
from any station in the group, including the associated station. Any speaker
associated with a station with its mute jumper in the off position will not be
muted when a paging call is made from any station in the group, including the
associated station.
Note: Paging calls
originating from stations
outside the group will be
heard regardless of the
position of the Mute
jumper.
If it is desired to bypass a station in a group, connect the group paging wires to
the PARK terminals of that station.
EXAMPLE OF GROUP MUTING
If the Group Mute Signal Conductors are attached to the Park terminals of station “B” that station will be
bypassed and paging from stations “A” or “C” will have no effect on the output of the loudspeaker
associated with Station “B”.
If the Group Mute Signal Conductors are attached to the Mute terminals of station “B” the condition of
the loudspeaker associated with that station will depend on the setting of the Mute On/Off jumper. If
the jumper is in the ON position the loudspeaker will be muted if a paging call is made from any of the
three stations. If the jumper is in the OFF position the paging call will not be muted if a paging call is
made from any of the three stations.
Paging calls from outside the Group will always be heard, regardless of the position of the mute jumper.

2. Test the proximity switch in the handset receiver cradle by moving a
small, permanent magnet over the area while listening on the handset for
the line to open and close.
3. If the movement of the magnet switches the on/off hook condition, the
magnet in the receiver cartridge of the handset may be weak – try another
handset. It is not necessary to wire in the new handset to perform this test
– if the new handset switches the on/off hook condition, replace the
existing handset with the new unit.
4. If the movement of the magnet does not appear to switch the on/off
hook condition the handset itself may be defective – try another handset.
5. If these remedies do not correct the problem return the module for
repair.

Cleaning Tips for Guardian Communication Products
Guardian Products 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 Product may be cleaned with any general-purpose
household glass and surface type cleaner. Do not spray the Product 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 Product. Remoistened novelettes may also be used, however, avoid those containing lanolin
or aloe as they will leave a slippery residue. The handset and surface of the Product 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.
