Safety Messages • After installation, service, or maintenance, test the siren system to confirm that it is operating properly. Test the system regularly to confirm that it will be operational in an emergency. • If future service and operating personnel do not have these instructions to refer to, the siren system may not provide the intended audible warning and service personnel may be exposed to death, permanent hearing loss, or other bodily injury.
General Description General Description Introduction Federal Signal Modulator Series siren products are a family of electronic sirens that are capable of producing high-intensity warning signals over a large area. The siren consists of a speaker array and Control/Battery Cabinets. A highly efficient design enables the siren to produce a high-sound level while making moderate demands on the power source.
General Description • 360º coverage without sound variation in horizontal planes • Easy servicing through convenient access panels • Anechoic chamber-certified • Optional visual signaling options that enhance the Modulator’s intelligible voice communication and signaling • New models offer steel/concrete pole mounting solution The following is a picture of the Modulator.
Specifications Ordering Information Contact our Federal Signal sales engineers to design a system that meets your specific requirements. Specify speaker array model number. Each speaker array model must be ordered with a specific corresponding UV and amplifier. Table 2 Ordering Information Speaker Controller UV + 1 UV400...

Installation Installation Read and adhere to all safety warnings in this manual before installing the Modulator Series Speaker. Determining a Suitable Location The output level of the sirens is capable of causing permanent hearing damage. To prevent excessive exposure, carefully plan the siren location and post warnings where excessive levels may be encountered.
Installation Assuming a typical 10 dB loss per distance doubled and a 70 dB minimum sound level required to warn a typical urban area, the effective range of a MOD6024B is approximately 3,900 feet. Optimum warning is obtained when the warning signal is at least 10 dB above ambient. Do not expose personnel to sound levels above 123 dBC.
Installation 3. Hand tighten approximately a half turn after gasket engagement. 4. Locate the two (2) wires tie wrapped near the end of the horn throat. Note the label on the back of the drivers and connect the solid wire to terminal 1 and the striped wire to terminal 2 and white jumpers from 1 to 2 as shown in “Figure 6 Driver Connections”...
Installation To mount the siren on the Class 2 utility pole using the three-foot-long angle iron legs: 1. Uncrate the siren and remove the nuts that hold the siren on the shipping base. Install drivers if needed. Lift the siren approximately 3-1/2 feet with a crane or hoist. NOTE: To protect the speaker arrays from damage during shipping, all models have been shipped without drivers installed.
Installation NOTE: Siren cable is run through the center of the mounting plate through the steel pole. Siren cable can be pre-assembled through center of mounting plate for a no conduit installation. The eyebolt does NOT have sufficient strength to support the combined weight of the siren and a utility pole.
Installation Installing Lights on the Siren Modulator models can be ordered with optional top lights and/or side lights. If not ordered with the Modulator siren, they can be added later by purchasing the Top Light Kit (Federal Signal part number 191XL-024R) or Side Light Kit (Federal Signal part number MOD-QF-KIT).
Installation Installing the Side Light Kit The Side Light Kit is installed on the bottom (inactive) module. See Figures 9 and 10. To install the Side Light Kit: 1. Replace the standard driver access doors with the side light mounting doors. 2.
Maintenance Pre-Operation Checkout After the siren has been completely installed, perform the following checks before putting the siren into service. The output sound level of a siren is capable of causing severe hearing discomfort or permanent hearing damage. Therefore, ALWAYS wear appropriate hearing protection when performing tests or maintenance on the siren, and post warnings to warn people before they are exposed to excessive sound pressure levels.
Getting Service Replacing the Driver To determine if a driver is defective, refer to the procedure outlined in the installation instruction for the amplifier control unit or remove the speaker circuit from the terminal block and measure the impedance of the circuit. The impedance of each 400 W cell of the siren will measure approximately 4.5 ohms.
