b) Station Components Defined
Rotor Control Box - This component (located on the inside of the upper cabinet door)
activates the rotor motor after receiving commands from the control board. It also
transmits the rotor position to the control board. Connections are as follows:
RC1 - Connects the Rotor Control Box to the Control Board
RC2 - Connects the Rotor Control Box to the Rotor
RC3 - Provides Battery Voltage to the Control Box
This component is fused @20Amps.
Control Board - This component (located on the inside of the upper cabinet door) controls
the key functions of the WPS4000 system including:
Tone Generation
Event Timing
Remote Station Status Reporting* (encoding)
System Diagnostics (incl. SI TEST®)*
Remote Activation
Rotor Control
Local Control
* optional equipment
The control board contains a microphone jack for public address and a serial port to allow
connection of a computer (hereafter referred to as a PC) to the remote station. The control
board is also the location of the diagnostic LED’s.
Siren Amps - These components (located on the rear cabinet wall) receive the desired tone
or message generated by the control board, amplify it and deliver it to the siren driver.
Siren Driver - This component (located in the speaker assembly) produces the desired
audible tone or voice message.
Radio or Landline Board (Optional) - This component (located on the inside of the upper
cabinet door) receives signals from either the antenna or landline and delivers them to the
control board for processing. Through the use of the included radio, the station is also
capable of transmitting status information back to the control center.
Page 6
Motherboard - This component (located on the inside of the upper cabinet door) distributes
Battery Voltage and signals to all system components that require this voltage. The
motherboard is fused @5 Amps to protect all connected components EXCEPT for the siren
amplifiers and the rotor (they contain their own fuse). The 2nd motherboard (WPS4000-8
only) distributes signals between the amplifiers and the control board.
AC Battery Charger - This component (located on the bottom front of the cabinet door)
uses 110 VAC (or optional 220 VAC) single-phase service to maintain the stations batteries
at their proper voltages.
Solar Regulator (optional) - This component (located on the bottom front of the cabinet
door) uses electrical energy collected by a pole-mounted solar panel to maintain the station
batteries at their proper voltages.
Ammeter - This component (located on the battery charger panel) provides a visual
indication for the charge current flowing into the batteries from the charger or regulator.
Voltmeter - This component (located on the battery charger panel) provides a visual
indication of the DC voltage across the batteries.
Auxiliary Control Status Board (optional) - This component (located on the right inside
wall of the upper cabinet) is wired to remote switches to facilitate remote operation of a
specific siren station.
Batteries - These components (located on the inside of the lower cabinet) provide the
28VDC necessary for the system to operate.
Battery Disconnect Switch - This component (located on the rear inside wall of the
electronics cabinet) allows all system batteries to be completely disconnected from the
system. NOTE: This switch does not disconnect the batteries from the battery charger or
regulator.
Antenna Poly Phaser (optional) - This component suppresses high-voltage (static) charges
that could be present on the antenna.
Page 7
Antenna (optional) - This component (located on the utility pole) is capable of either
receiving signals broadcast from the control center (one-way) or can both transmit and
receive signals to and from the control center (two-way), depending how the system was
ordered.
Solar Panel (optional) - This component (located on the utility pole) collects solar energy,
converts it to electrical energy and delivers it to the Solar Regulator to maintain the station
batteries at their proper voltage.
Strobe Control Board (optional) - This component (located on the rear inside wall of the
electronics cabinet) is a user-defined device that controls a pole-mounted strobe light. This
light can be configured to activate during specific conditions (example: when any tone or
message is generated).
Intrusion Alarm (optional) - This sensor (located on the controller front panel) detects the
opening of the cabinet door. If the station is equipped with this option, the alarm is
configured to transmit a signal back to the control center.
Page 8
Section II: System Operations
a) Remote Operations
Remote operation of a WPS-4000 series siren involves transmitting signals from the control
center to the desired station. This is accomplished by using either an encoder and
transmitter or, if the station is so equipped, using an auxiliary control status board that has
been wired to switches/controls at the control center. Remote operation is beyond the scope
of this document and will therefore not be addressed. If your system is equipped with an
encoder, please refer to the encoder operating manual for information regarding remote
operation. If your station has been wired to use the auxiliary control status board, refer to
the reference materials provided by the electrical engineer or installer.
b) Local Operations
Local operation is accomplished through the control panel on the front of the station
cabinet. The functions of these controls are as follows:
Cancel
Abruptly stops siren tones without the normal “ramp
down” found in several tones. Helpful in the event of an
accidental tone activation.
Wail
Produces a slow rise and fall tone.
Attack
Produces a faster rise and fall tone (used for designated
Civil Defense National Attack tone).
Alert
A steady tone (Civil Defense alert).
Whoop
A repetitive rise-only tone.
Hi-Lo
An alternating two-tone sound.
Air Horn
A pulsing air horn sound.
SI TEST®
Initiates SI TEST® tone and the optional diagnostic SI
TEST® routine.
Xmit Carrier
Actuates remote station radio transmitter PTT circuit.
When tone squelch is used with the transmitter, the
transmit carrier function is used when adjusting tone
squelch modulation.
Page 9
Xmit Audio
For use with remote station radio transceiver, causes
transmission of DTMF tone via RF link for tone
modulation adjustment.
Xmit Status
Transmits station status information and battery voltage
to the control center
DVM Test
Activates the Digital Voice Message (DVM) assigned to
the test procedure in the configuration software.
Rotor CW
Momentary switch actuates rotor motor to rotate
speaker in a clockwise direction.
Rotor CCW
Momentary switch actuates rotor motor to rotate
speaker in a counter-clockwise direction
Keyboard Arm
Enables local station operation via keypad. Once
pressed, the keypad remains active until either a)
another keypad button is pressed, or b) 60 seconds have
elapsed, whichever comes first. The Keypad Arm button
must be pressed each time a keypad button is to be
pressed. Note that the Cancel button is always enabled
and does not require Keypad Arm to be pressed.

Section III: Understanding Station Addressing
Every Siren Station in a given area code has its own, unique “Station Address”. This address
allows the user to select an individual or a group of stations. As stated elsewhere in this
manual, a valid station address can be any number from 0000 to 9999. This allows for
10,000 unique addresses; a staggering number of stations to keep track of. Although it is
logistically impossible to have that many stations in a single area code, it does illustrate the
importance of a sensible, intuitive numbering convention for station addresses. This section
will outline two types of conventions
Central Point Source: Quadrant, Sector, Radial & Station
Frequently, warning systems are used to notify the public of emergency situations that may
occur from a single, centralized location. Typically, siren stations would be located
throughout a 360° area surrounding this location for a specified distance from the source. In
this scenario, the Central Point Source convention would be well suited.
For illustration purposes, assume the siren stations are installed within a 5 mile radius of the
Central Point. As such, a Quadrant, Sector, Radial & Station numbering convention would
allow the selection of any of the following:
•
any siren station
•
all siren stations
•
any one of four sectors
•
any one of 5 radii within the sectors
The area of coverage in this system, a circle, is divided into 4 quadrants. Each quadrant is
then divided into 4 sectors. Each sector is further divided into 5 segments or radii emanating
from the center of this siren system.

In this system, a stations address is structured as follows:

Quadrant (1 to 4)
2
Sector (1 to 4)
3
Radii (1 to 5)
4
Individual station within a radian
Here are some sample activations to further illustrate this concept.
Sample 1:
A station with address 1354 would be located in:
Quadrant:
1
Sector:
3 of Quadrant 1
Radial:
5
Station:
4
If an operator selects station 1-3-5-4, only that station will be selected, as shown.

Sample 2:
If the activation of a group of remote stations within a whole segment of a radius within a
quadrant and sector is desired, the fourth digit address is substituted with a “Wild Card”,
the “#” pound sign.
An address selection of 1 - 3 - 4 - # would activate the system as follows:
Quadrant:
1
Sector:
3 of Quadrant 1
Radial:
4
Station:
# All stations defined by above
This selection is shown below.

Sample 3:
Selection of an entire sector can be accomplished by using the following address:
Quadrant:
1
Sector:
3 of Quadrant 1
Radial:
# All radial 1 - 3
Station:
# All stations defined by above
In selecting a sector, the first two digits of the address are set for the sector address, for
example 1 - 3 (Quadrant 1 - Sector 3). The third and fourth digits are substituted with a #
(Wild Card). Therefore, the address to select all stations in sector 1-3 is 1 - 3 - # - #. This
selection is represented below.

Sample 4:
The selection of a complete quadrant can be achieved by using the following address:
Quadrant:
1
Sector:
# All sectors of Quadrant 1
Radial:
# All radials in 1 - 3
Station:
# All stations defined by above

Governmental: County, City & Station
For this next type of address structure, assume that the siren system in question is used
primarily for tornado warnings throughout a major population center. This center
encompasses three counties with each county having no more than ten cities. Two cities
contain more than 50 high-power voice and siren stations.
The following represents a Governmental System 4-digit address configuration, allowing
activation by “All Call”, county group activations, city group activations and individual
station activations:

Section IV: Troubleshooting
Audio Loss
If after activating the siren there is no audio output, perform the following procedure step
by step. This procedure will require a digital multimeter.
1.
Locate the Audio Presence LED on the controller board (see “Fig. 6: System LED
Diagnostic Indicators” on page 30). When audio is present on the board, this LED
will be on.
2.
Activate the WAIL siren tone from the control panel on the siren cabinet. Confirm
that the Audio Presence LED is on. If this LED is not on or if it turns off quickly,
measure the battery voltage. The siren will not activate if battery voltage drops below
19 VDC. Be sure to measure the battery voltage at the same time you activate the
siren. The batteries may show a good float voltage while they are not under load, but
upon activation, the battery voltage may drop below 19 VDC if their capacity is low.
Note that when the siren shuts down and the load is removed from the batteries, the
voltage may rapidly return to 25 VDC or more. If this condition is occurring, the
batteries will need to be replaced. If the voltages are in the normal range, proceed to
step 3.
3.
Locate connector J2 on the control board. With your multimeter set to AC volts,
measure across pins 6 and 7 (White with Orange stripe and White with Brown
stripe). With the siren tone running, 5 VAC should be present. If no voltage is present,
the controller board is probably at fault.
NOTE: Confirm that the audio presence LED is on while performing these
measurements. It indicates that the siren controller is still activated. If the specified
voltages are present, proceed to step 4.
4.
With the siren tone still active, measure across pin 1 (Blue wire) and pin 2 (Black w/
White trace) on each of the siren amplifiers. 5 VAC should be present at each
amplifier. If so, proceed to step 5. If no voltage is measured, this is indicitive of a
wiring problem between the controller board and the siren amplifiers. Check the
wiring between these components
5.
Remove the Red siren driver lead from each siren amplifier. Press “Cancel” on the
control panel and then press “Wail”. Measure across the output of each amplifier
(White Weco connector) with the siren driver disconnected. 70 VAC should be
measured. If this voltage level is measured, proceed to step 6. If this voltage level is
not found and 5 VAC was measured at the input, proceed to step 7.
6.
Set your meter to measure resistance at its lowest scale. Measure across each of the
speaker drivers, making sure that at least one wire of each driver is removed from
the power amplifier (or else the transformer in the amp is being measured as well).
Each driver should have a DC resistance of approximately 3 Ohms +/- .3 Ohms. If a
resistance value outside of this range is found, contact factory.
Page 18
7.
Set your meter to measure DC Volts. Connect the negative lead of your meter to
ground (one of the solid black wires in the multi-position connector on the amplifier
is a good ground source). With a siren tone activated, measure the following wires for
the following voltages (approximately):
Wire

Brown
Solid White (all)

AC Battery Charger
The AC-powered battery charger has two charging modes: Equalization Mode and Float
Charge Mode. The charger is in equalization mode when AC power is first applied; the
charger will stay in equalization mode until the battery voltage reaches approximately
30VDC. Once the battery voltage reaches that point, the charger will switch to float voltage
mode. In that mode it will charge the batteries to the appropriate voltage relative to the
temperature of the batteries (25 to 29VDC).
The AC battery charger contains three circuit boards. The filter board contains a single,
green LED, while two charging boards each contain a pair of LED’s, one green and one
yellow. This pair of LED’s provides diagnostic information for the battery charger. The
following chart defines their various diagnostic states.

Solar Regulator
The following procedure can be performed to confirm proper operation of the solar
regulator:
1.
Disconnect the solar panel from the charger. With a DC voltmeter, measure the
voltage across the wires coming from the solar panel. The voltage should be greater
than 32 VDC (NOTE: The solar panel must be in direct sunlight).
2.
Reconnect the solar panel to the charger. Monitor the battery voltage with the
cabinet voltmeter. The float voltage will vary between 25 to 30 VDC, depending on
battery temperature. When the solar regulator is charging, the DC LED on the
circuit board will be on. During normal operation the charger will cycle on and off.
The float voltage will vary with battery temperature. The following is a brief description of
the normal charging cycle:
If the float voltage for the current temperature of the batteries is 26 VDC, the regulator will
turn on at 26 VDC (LED will come on) and it will charge the batteries to 28 VDC. Once the
battery voltage reaches 28 VDC, the regulator will turn off (LED will go off), and the
battery voltage will be allowed to drop to 26 VDC. The cycle would then repeat itself. If the
float voltage was 27 VDC, it would cycle from 27 VDC to 29 VDC.
When AC power is applied to the battery charger, the following voltages should be
measured on the wires coming off the charger:
Note: Refer to “Fig. 1: Station Wiring Diagram” page 3.

1.
Remove all amplifier fuses.
2.
Install an 8 ohm speaker at amplifier audio input connector pins 1 and 2 (Blue and
Black w/White wires) in the 16 position connector.
3.
Select a siren tone by pressing one of the controls on the front panel.
4.
If the tone can be heard through the speaker, press the DVM-Test control to play the
predesignated message.
Partial or Full Diagnostic Failure
This procedure is to be used if the Partial or Full diagnostic LED (located on the controller
board) indicates that a problem has been detected. A Partial indication means that at least
one speaker and/or amplifier is operational. A Full indication means that all speakers and
amplifiers are operational. NOTE: In order for a good Full indicator to be valid, a good
Partial indicator must also be present).
1.
Connect the PC to the siren station via the com port on the front of the siren cabinet
control panel.
2.
Display the “Status” screen on the PC.
3.
Press the SI TEST® control on the front control panel.
4.
Each amplifier contains a red LED that is visible on the front of the control panel.
Note if all the LED’s are on. Click the “Update Status” button on the PC and note
which amp is displaying an error.
5.
Open the front panel and swap the speaker driver wires from the amplifier that
indicated a failure, with an amplifier with a lit LED. For example: if the LED for
amplifier 1 is the only LED not on, install amplifier 1 speaker wires onto amplifier 2
and install amplifier 2 speaker wires onto amplifier 1. This will diagnose if it is the
speaker or the amplifier that has failed. You may also measure the DC resistance of
the speaker driver with your ohm meter. Be sure that the speaker driver wires are
disconnected from the amp prior to measuring. A good driver will read 3 ohms +/- .3
ohms.

Section V: Maintenance
Although The WPS-4000 is of a dependable, solid-state design, periodic activation, field
inspection and preventive maintenance is recommended to insure the maximum
performance of each station.
Frequency of Testing and Activation
A system of twice-monthly activation and confirmation, combined with a quarterly service
and preventive maintenance is recommended to help insure the successful performance of a
station. Increasing the frequency of testing will support and improve a station’s test record.
Stations located in environmentally adverse locations will require inspection and preventive
maintenance at more frequent intervals than just discussed. Stations should always be
inspected following severe storms.
If a station is activated by remote control (landline or radio), the twice-monthly activation
should be performed using the remote control link.
The twice-monthly activation of a station can be confirmed by several different methods,
depending upon the options selected with each Whelen System.
Local Site Confirmation
For a basic station activated at the cabinet, or by landline or radio, have an observer
confirm that the station activated audibly. The observer should report successful as well as
failed station tests. Station Performance Logs should be maintained. It is important to
understand that audible confirmation alone is not assurance that the station is operating at
100% power. This requires inspecting the station in greater detail.
Stations may be optionally equipped with counters that advance upon radio or tone
generator activation. These counters do not confirm total operation or the final expected
output of an outdoor warning device.
If a station is equipped with SI TEST® diagnostics (optional), the station’s activation may
be confirmed using SI TEST® or full power siren mode. Following an activation, SI TEST®
displays its information on control board mounted LED’s or through a LED display board
visible on the right side of the cabinet. Fig. 17 shows the location and function of the LED’s
on the control board. The cabinet mounted display board LED’s will confirm the following
(from Left to Right):
Red
Yellow
Red
Green
Red
AC Power
DC Power at minimum proper operating level
Partial Amplifier and Speaker Driver Operation
Full Amplifier and Speaker Driver Operation
Rotor Operation
Page 22
Following activation and observation the results should be noted in the performance log.
Any indication of incomplete operation presented by the LED indicators should prompt
IMMEDIATE service attention.
The SI TEST® system retains information until cleared by a specific command.
The SI TEST® information stored at the station, if not cleared, will update itself
automatically with subsequent SI TEST® activations.
Remote Monitoring and Confirmation
Stations equipped with the optional Whelen COMM/STAT™ Command and Status
Monitoring control, allow remote monitoring of status as well as confirmation of system
activation. COMM/STAT™ returns the results of a remote station activation (both SI
TEST® and siren warning mode) in a DTMF encoded format via radio link.
Remote monitoring by RF link eliminates the necessity of physically visiting a station to
confirm an activation.
Following the activation of a station, a “Status Request” may be sent to that station by
DTMF encoded radio command. Diagnostic SI TEST® information is then presented to the
status encoder at the station, converted into DTMF code and transmitted back to the control
center, where one of several COMM/STAT™ base station products will convert the DTMF
code into meaningful information.
Quarterly Maintenance
Developing a quarterly inspection and preventive maintenance program for an outdoor
warning station requires a thorough understanding of all the elements and expectations of
the system. The following section provides an overview and basic guideline for quarterly
station inspection and preventive maintenance program for the sample station.
Page 23
Visual Siren Station Physical Inspection
•
Observe the speaker cluster, siren cabinet and AC Service for any signs of damage or
loose mounting hardware (Some shrinkage of a newly treated utility pole may occur in
the first several years following installation, requiring the tightening of mounting
hardware.
•
Check all conduit for watertight connection and entrance into the siren cabinet.
•
Inspect the AC Service for damage, blown fuses, degraded (corroded) power connections
and integrity of the lightning arrestor.
•
Inspect the grounding system for AC Service, Siren Cabinet and pole top equipment.
Verify connections and acceptability of earth ground.
•
Observe the pole for any shifting and/or leaning. Poles that are not plumb will not
properly direct alerting sounds.
•
Examine entire station for any signs of vandalism or forced entry.
Siren Cabinet and Components
•
Inspect AC Outlet, fuse and surge suppression equipment. Examine system for
infiltration of foreign material(s), rodents or other pests.
•
Inspect and, if necessary, clean all drain holes and vent screens.
•
Inspect battery terminal connections and clean if necessary. Re-apply silicone coating to
battery terminals if necessary. Observe battery voltage with siren in inactive state (AC
power must be on to station, otherwise station must be powered up to observe meter).
•
Examine all wiring harnesses for chafing. Verify wiring terminations for tightness and
wiring connections for proper electrical connections. Replace and correct any corroded
or marginal connections. Inspect antenna for proper connection.
Speaker Assembly and Pole Top Equipment
NOTE: Any examination of Pole Top equipment should be performed with the station audibly
disabled.
•
Inspect speaker for blockage by rodents, pests or other foreign material. Clean if
necessary. Inspect any wiring cables or harnesses for chafing. Inspect the siren driver
compartment for infiltration of foreign materials, rodents or pests. Clean if necessary.
Confirm that the driver compartment will allow for water or moisture drainage. Inspect
speaker wiring connections for any sign of corrosion.
Page 24
•
Verify tightness of all mounting hardware.
•
Check all wiring terminations and connections.
•
Verify lubrication of the rotor gear train. The recommended inspection interval is
initially 6 months. Following the initial two inspections, the owner may determine if a
longer inspection interval is acceptable. Varying weather conditions will affect this
interval. Many stations are located in areas of the country where an annual inspection/
lubrication interval is acceptable.
Station Performance Testing
NOTE: Depending on local conditions and station options selected, the station may be tested
on or off line. Off line testing of the station involves disconnecting the speaker drivers
from the siren amplifiers, so as not to disturb the public when verifying tone generator
operation. A complete test must, however, include the testing of the siren amplifier
operation. This can be accomplished inaudibly on units equipped with SI TEST®.
Other units must be audibly tested.
A basic routine, verifying the performance and operation of the sample station previously
described, would be as follows:
1.
Local and Remote Activation Activation of each remote station function by local control and remote control. With
amplifiers on and off line as needed. An examination of each activation function will
also facilitate a verification of related and subsequent system module activations and
electrical connections that would be caused by an activation command. Also confirm
function time outs (ex.: does the Alert signal time out at three minutes as per user
specification?).
2.
Response to Station Address and All Call address programming Control Center reception and activation on SI TEST® or non-tone activation, for
individual station address and All Call address selection.
3.
Public Address - With the station on line, activation of PA for both local and remote
control, verifying PA Audio path and proper set up level of volume. Verify AC drop
out on PA.
4.
Siren Amplifiers Inspect for complete operation with speaker drivers (observe LED’s).
Page 25
5.
SI TEST® Station Analysis Observe and confirm diagnostic status of:
AC
DC
Partial Amplifier & Speaker Driver Operation (disable one amplifier to confirm this
test).
Full Amplifier & Speaker Driver Operation
NOTE: Verify AC drop out during SI TEST® mode.
6.
Battery Charger Operation Observe for proper charging operation.
Verify AC drop out in PA or SI TEST® mode.
7.
Batteries Verify voltage stability under load.
Perform a load test.
8.
Status Encoder Perform a diagnostic SI TEST® of the station and compare status information with
observations made locally at the station.
Disable one speaker and verify that the “Full” LED indicator is off.
Disable AC and verify that the “AC” LED indicator is off.
Compare battery voltage return status with observed and measured battery voltage.
9.
Transmitter Check status encoder DTMF tone level modulation with transmitter.
Check transmitter set up.
Verify power output and SWR.
Page 26
10.
Rotor Activate rotor by the “CW” or “CCW” control on the control panel and observe the
ammeter. The ammeter should read approximately 3 to 5 amps. A higher reading
indicates gear train binding and that lubrication is needed.
Exercise the rotor through complete CW rotation. Verify that the rotor stops at limit
(360°), requiring the CCW control to be pressed. Repeat process with a CCW
rotation and verify that the rotor stops at its limit.
By remote control (or using the PC), index the rotor to the four main compass points
(North, South, East and West). Confirm proper orientation and operation.
By remote control (or using the PC), index the rotor to CW 45° increments between
the four main compass points. Confirm proper orientation and operation.
By remote control (or using the PC), index the rotor to CCW 45° increments between
the four main compass points. Confirm proper orientation and operation.
NOTE:On concluding any examination of a station where connectors have been opened and
closed , a final radio test by either SI TEST® or full power should be performed and the results
observed for a complete successful test. The PA audio path should also be audibly verified by
sending PA and broadcast a voice message.
The following is a sample form that may be used for quarterly inspection and maintenance.
