![]() ![]() ![]() The sirens can be activated by radio using single tone, two-tone, DTMF, MSK or POCSAG over analog, digital and trunking systems, or by satellite, cellular, landline or IP. They have also been known to play Star Spangled Banner during tests on or near the 4th of July, and also on military bases. If properly equipped, the Modulator can also employ voice notification to give specific information or to give a more clear understanding of an emergency situation. The seven standard tones are Wail, Alternate Wail, Pulsed Wail, Steady, Alternate Steady, Pulsed Steady and Westminster Chimes. Similar to Federal Signal's previous Electronic Outdoor Warning Siren series, the Modulator can produce seven standard warning tones. They provide the same alerting technology as the original modulator, with the exception of a smaller compact chassis and cylindrical modules instead of elliptical ones. In January 2013, Federal Signal released the Modulator II sirens, consisting of the 1004B, 2008B, 3012B, 4016B, 5020B, 6024B, and 8032B models. The first family of modulator arrays consisted of eight different models, as follows: 1004, 2008, 3012, 4016, 5020, 6024, 6032, and 6048. Modulator model numbers identify the number of cells, as well as the number of drivers. When they were first made, they were used with Modulator Control Plus(MPC) and basic/standard Modulator Controls. Modulators that are being made now use the UltraVoice controller. Due to the design of active cells, there would be unbalanced sound distribution without the inactive cell. Modulators have an inactive (dummy) speaker cell on the bottom of the stack that is used to help project sound in all directions. The modulator is composed of speaker cells (ranging from two to eight, with the exception of seven) that contain four speaker drivers per cell, although two models (model 60) had additional drivers available when they were still produced. The Modulator II is sold based on the more compact chassis of the siren compared to the original Modulators. They are identified mostly by their distinctive stacked "flying saucer" design. Tone frequency range 36.6 to 254.1 Hz, Tone accuracy >.Electronic public warning siren A Federal Signal Modulator siren in Bay Head, New Jersey.įederal Signal Modulators (also known as Modulator Speaker Arrays) are electronic warning devices produced by Federal Signal Corporation that are used to alert the public about tornadoes, severe weather, earthquakes, fires, lahars, tsunamis, or any other disaster. Spurious Response & Image Rejection (dBm) per EIA-603, part 4.1.8 ![]() Intermodulation Rejection per EIA-603, part 4.1.9Īdjacent Channel Selectivity per EIA-603, part 4.1.6 Informer units are factory programmed for narrow-band operation and come with a one-year warranty (see owner’s manual). Units are pre-wired to accommodate the LP1 Strobe which operates off the Informer’s internal power supply. These models feature mounting holes for easy top mounting of an optional Federal Signal LP1 Strobe light. Informer I-HIOW and I-UIOW receivers include a 115/230VAC power supply pre-wired to internal terminal blocks and a built-in battery backup. All wiring is contained within the aluminum case, and five pre-punched, easy-to-remove conduit holes are available to facilitate wiring connections into and out of the unit. Informer I-HIOW and I-UIOW receivers are designed to be wall mounted or recessed into the wall. All wiring is routed to connectors located on the back of the unit for convenient access. The Informer I-HIO and I-UIO desktop versions feature an external AC transformer for power, as well as built-in battery backup. The receiver can be programmed to disable the"monitor" button in order to prevent end-users or unauthorized persons from listening to local-channel activity. Other features include a 600-Ohm audio output, dual (N.C./N.O.) relay for external control, built-in diagnostics, and an LED test indicator. Informer units include a LED panel that flashes to immediately indicate transmission of an emergency alert. Standard units decode DTMF, single-tone, and two-tone sequential signals (optionally available are units for decoding EAS/SAME or Federal Signal digital protocols). The Informer is capable of generating four separate alarm sounds that can be accompanied by a live voice message. Informer Radio receivers come in either VHF or UHF-band models. Informer units are designed for one-way radio alerting applications. Alerting the public of an emergency situation is now easier and more reliable than ever with Federal Signal’s Informer I-HIO and I-UIO radio receivers. ![]()
