The Whelen Firehouse Series: Omni-Directional Sirens Built for Rapid Response
When seconds matter most, clear and immediate notification is essential to mobilizing fire crews and safeguarding surrounding communities. The Whelen Firehouse Series omni-directional siren systems deliver powerful, dependable tone warning and visual alerting capabilities that ensure both firefighters and the public receive urgent information without delay. As a trusted Whelen partner, MCA has long supported fire departments nationwide in implementing these robust, American-made solutions to strengthen operational readiness.
Trusted, Purpose-Built Design for Firehouse Applications
Specifically engineered for firehouse applications, the Firehouse Series combines Whelen’s renowned omni-directional acoustic technology with rugged construction, ensuring maximum performance and reliability under the most demanding conditions. Each system features one to four high-efficiency 400-watt EZ-PULL™ speaker drivers, providing scalable sound output to match the unique needs of each station and community.
Available FHS Siren System Models:
- FHS1: One speaker cell, one amplifier
- FHS2: Two speaker cells, two amplifiers
- FHS3: Three speaker cells, three amplifiers
- FHS4: Four speaker cells, four amplifiers
Each system is housed in a durable Type I aluminum cabinet, includes a pole top mounting bracket, and comes with a 50-foot cable for straightforward installation and integration. These features ensure that firehouses of all sizes can deploy a system tailored to their specific requirements.

Why Mass Notification Systems Are Critical in Firehouses
With over 27,000 fire departments running over 51,000 fire stations across the United States and more than 1.2 million firefighters, the need for rapid and reliable communication systems is paramount. Fires today are more dangerous than ever, with synthetic materials in modern construction reducing the time to safely escape a burning building from 17 minutes in the 1980s to just 3 minutes today. Flashovers—when a room ignites all at once—can occur in as little as 5 minutes. This means firefighters must respond faster than ever to save lives and property.
A Mass Notification System ensures that firefighters are alerted the moment a call comes through dispatch. These systems notify on-duty crews inside the firehouse while simultaneously alerting pedestrians and vehicular traffic outside the station, ensuring a safe and efficient response.
Rapid Activation and Comprehensive Control
Whether firefighters are sleeping or actively preparing, the Firehouse Series ensures immediate notification at any hour. The systems support a wide range of activation methods, including:
- Local push-button control
- Landline activation
- VHF high-band and UHF narrow-band frequencies
- MOSCAD/ACE, FSK, and two-tone sequential signaling
Standard and optional control boards (FAUXIN for one-way or FAUXCS for two-way) provide flexible contact closure activation and status monitoring, enabling seamless integration with dispatch and local systems.
Advanced Features for Operational Assurance:
- SI TEST® Silent Diagnostics: Verifies system readiness without disrupting station operations.
- Low Battery Alarms: Adds an extra layer of operational assurance.
- Two-Way Controls: Enable real-time status monitoring and activation feedback.
Superior Acoustic and Visual Warning Capabilities
The Firehouse Series delivers six standard public warning tones—Wail, Whoop, Attack, Hi-Lo, Alert, and Airhorn—designed to cut through environmental noise and capture attention both inside and outside the station. For enhanced situational awareness, optional visual alerting accessories can be added, including:
- 24 VDC LED Beacons: Available in amber, blue, clear/white, or red.
- VisuAlert™ 360-Degree LED Module: Provides all-around visibility to protect pedestrians and vehicle traffic during emergency dispatches.
These features ensure that both auditory and visual alerts are unmistakable, even in high-noise or low-visibility conditions.

Reliable Power and Sustainable Options
The Firehouse Series is designed to perform even during power outages or grid failures. Key power features include:
- Battery-Powered Operation: Ensures a minimum of 15 minutes of full-output performance.
- AC Temperature-Compensated 5-Amp Battery Charger: Simplifies ongoing maintenance.
- SLIDEOUT™ Battery Tray: Allows for easy access and replacement.
- Solar Power Option: Dual 80-watt panels with an integrated regulator provide dependable off-grid or supplemental power support.
These power solutions ensure that firehouses remain operational and responsive, no matter the circumstances.
Built for Harsh Conditions
Each Firehouse Series system is engineered to withstand harsh environmental exposures and demanding operational cycles. From severe weather conditions to high-noise industrial environments, these systems deliver consistent, reliable performance year-round. The rugged construction and advanced technology ensure that the system is ready to perform when every moment counts.
