Page 6: B) Station Components Defined
b) Station Components Defined Control Board - This component (located on the inside of the upper cabinet door) controls the key functions of the WPS2900 system including: Tone Generation Remote Activation Event Timing Rotor Control Remote Station Status Reporting* (encoding) Local Control System Diagnostics (incl. - Page 7 Solar Regulator (optional) - This component (located on the inside of the lower 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 inside of the lower cabinet door) provides a visual indication for the charge current flowing into the batteries from the charger or regulator.
- Page 8 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.

Page 9: System Operations A) Remote Operations
Section II: System Operations a) Remote Operations Remote operation of a WPS-2900 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. -

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. -
Page 11: Understanding Station Addressing
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;... -
Page 12: Fig. 5: Single Station Selection
In this system, a stations address is structured as follows: Digit Allocation Quadrant (1 to 4) Sector (1 to 4) Radii (1 to 5) 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: Sector:... -
Page 13: Fig. 6: Group Selection - Radial Sector
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: Sector: 3 of Quadrant 1... -
Page 14: Fig. 7: Group Selection - Sub Sector
Sample 3: Selection of an entire sector can be accomplished by using the following address: Quadrant: 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). -
Page 15: Fig. 8: Group Selection - Quadrant
Sample 4: The selection of a complete quadrant can be achieved by using the following address: Quadrant: Sector: # All sectors of Quadrant 1 Radial: # All radials in all sectors of Quadrant 1 Station: # All stations defined by above When selecting a quadrant, the first digit designates the Quadrant (1). -
Page 16: Fig. 9: Group Selection - All-Call
Sample 5: All stations in a system may be accessed by using the Wild Card (#) for all address numbers. The address would be # - # - # - #. Quadrant: # All Quadrants Sector: # All sectors of all Quadrant Radial: # All radials of all sectors of all Quadrants Station:... -
Page 17: Governmental
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. -
Page 18: Troubleshooting Audio Loss
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. Locate the Audio Presence LED on the controller board (see “Fig. 11: System LED Diagnostic Indicators”... -
Page 19: Solar Regulator
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): Grey 6 VDC... -
Page 20: Fig. 10: Solar Regulator Connector Pin-Outs
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. -
Page 21: Digital Voice
Digital Voice Remove all amplifier fuses. 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. Select a siren tone by pressing one of the controls on the front panel. If the tone can be heard through the speaker, press the DVM-Test control to play the predesignated message. -
Page 22: Frequency Of Testing And Activation
Section V: Maintenance Although The WPS-2900 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. -
Page 23: Quarterly Maintenance
This diagnostic function is enabled by either a full power siren tone activation or by performing a SI TEST®. The same information is available on the control board LED numbers 4 - 8. The “Status” option is not required for the on-board LED’s to function. Following activation and observation, the results should be noted in the performance log. -
Page 24: Visual Siren Station Inspection
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. -
Page 25: Station Performance Testing
• Verify tightness of all mounting hardware. • Check all wiring terminations and connections. 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. - Page 26 Batteries - Verify voltage stability under load. Perform a load test. Status Encoder - Perform a diagnostic SI TEST® of the station. 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”...
