Overview
ExP-1/-5 Explosion Proof Page/Talk Wall Stations
Guardian's Page/Talk Systems provide reliable and easy to use paging and communication within
industrial environments such as plants, mills and factories. Individuals can be paged from any
station and two or more persons can communicate on any available Talk line.
The Models ExP-1 (Single-line) and ExP-5 (Multi-line) stations described in this manual are designed
for use in Class I & II, Division 1 hazardous locations. Each ExP-1/-5 Wall Station provides up to
twelve watts of paging power for an external loudspeaker. A push button switch on the faceplate
puts the station into paging mode.
In order to avoid acoustical feedback from a loudspeaker receiving a signal from the station, a jumper
on the circuit board provides for the speaker to be muted when the Page button on the faceplate 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 Page/Talk stations and related equipment are compatible with systems provided by most
other manufacturers.

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.
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.
Note: Paging calls
originating from stations
outside the group will be
heard regardless of the
position of the Mute
jumper.
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.
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

STATION "C"
STATION "B"

GROUP MUTE
SIGNAL CONDUCTORS
If the Group Mute Signal Conductors of station “B” are attached to the Park terminals, that station will
be bypassed and paging from stations “A” or “C” or any other station in the system will always be heard
over the loudspeaker associated with Station “B”, regardless of the position of the Mute jumper.
If the Group Mute Signal Conductors of station “B” are attached to the Mute terminals 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.

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.
See: Figure 4 - Circuit
There are two controls on the circuit board to adjust the Ambient Noise Sensor
mechanism. The Paging Speaker Volume Control – which is accessible 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.

Station Stays On or Off Hook
1. Ensure power is being supplied to the station.
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.
