FEDERAL SIGNAL PA

Federal Signal PA horn speakers are available in indoor and outdoor variants, distinguished by their environmental sealing. Outdoor models, such as the AM300GCX-R and AM50-70B, are constructed with weatherproof enclosures and gaskets to resist moisture, dust, and UV exposure, making them suitable for unprotected locations. Indoor models like the AM50-25B and AM300-R lack these additional seals but are still built for industrial environments. Both types are powered and 1-way, but outdoor units typically have higher ingress protection ratings. Always verify the specific IP rating on the datasheet for your chosen model.

Federal Signal PA speakers are powered units, meaning they include an internal amplifier or driver that requires a low-voltage DC or AC power source, typically 24 VDC or 120 VAC depending on the model. The exact power consumption varies by speaker size and output level. For example, smaller models like the AM50-25B draw less current than larger units like the AM302X-R. Refer to the manufacturer's datasheet for each SKU to determine the specific voltage, current, and wiring requirements. 3G Electric provides datasheets with all orders to facilitate proper installation.

Yes, Federal Signal PA horn speakers are designed for both voice paging and tone signaling. Their 1-way driver configuration reproduces a wide frequency range suitable for clear voice announcements, while also handling continuous tones for alarms or alerts. The speakers are commonly integrated with public address systems, fire alarm panels, and industrial control systems. For optimal voice clarity, select a model with a larger horn diameter, such as the AM302 or AM300X, which provide better low-frequency response. All models are powered and require an audio input signal from a compatible amplifier or controller.

Federal Signal PA horn speakers are typically designed for surface mounting using a standard bracket or swivel mount, allowing adjustment of the horn's direction. The mounting hardware is usually included or specified in the datasheet. Models like the AM300-R and AM302X-R feature integral brackets for wall or ceiling installation. For outdoor installations, use corrosion-resistant hardware and sealant to maintain weatherproof integrity. Always follow the manufacturer's installation instructions to ensure proper acoustic coverage and environmental sealing.

Selecting the correct Federal Signal PA speaker depends on the area's size, ambient noise level, and required sound pressure level (SPL). Larger models like the AM302X-R (16 3/4 in wide) produce higher SPL and are suited for large open areas or noisy environments. Smaller models like the AM50-25B (5 1/2 in wide) are adequate for confined spaces or quieter zones. Check the datasheet for each model's SPL rating at a given distance. For multiple speakers, consider spacing to avoid dead zones. 3G Electric's technical support can assist with application-specific recommendations.
