Speco Technologies ER370B 16 Watt Deluxe Megaphone with Siren
Overview
The Speco ER370B is a 16-watt deluxe megaphone engineered for professional security and communication applications requiring high-output audio projection. Finished in matte black, this device combines megaphone functionality with integrated siren capabilities, making it suitable for access control integration, emergency notification, and perimeter security deployments where clear audio communication is essential.
Key Features
- 16-Watt Power Output: Delivers robust audio projection across outdoor and indoor security environments
- Integrated Siren: Multi-tone alarm siren for emergency alerting and threat deterrence
- Deluxe Design: Professional-grade construction with matte black finish for discreet integration into security infrastructure
- Megaphone Functionality: Clear audio transmission for public address announcements and evacuation procedures
- Access Control Compatible: Integrates with modern security systems for automated audio triggers and alerts
- Professional-Grade Audio: Engineered for reliable performance in institutional, commercial, and perimeter security applications
Deployment Applications
The ER370B is well-suited for facilities requiring integrated voice and alarm communication. Security integrators commonly deploy this device in entrance control stations, perimeter monitoring systems, and multi-tenant building announcement systems. The 16-watt output ensures intelligible audio coverage across typical institutional courtyards, parking areas, and outdoor security zones. The deluxe megaphone with siren combination eliminates the need for separate audio components, reducing installation complexity and system footprint.
System Integration
The Speco ER370B integrates with access control panels, intercom systems, and security management platforms supporting auxiliary audio output. IT managers and integrators can configure the device for triggered alerts, scheduled announcements, and emergency notification workflows. The matte black finish provides aesthetic compatibility with modern security installations while maintaining professional appearance in client-facing environments.
Reliability and Performance Standards
Speco Technologies manufactures professional-grade communication and security devices for institutional deployment. The ER370B carries the brand's standard construction quality and field-proven reliability across North American security integrations. Technical support and replacement availability are consistent with Speco's established distributor network.

The Speco ER370B brings straightforward, no-nonsense audio capability to security installations where voice communication and alarm functions must coexist in a single device. During integration planning, I find the 16-watt output and dual-function design (megaphone + siren) reduces wiring runs and panel connections compared to standalone components. The matte black finish integrates cleanly into existing security infrastructure without requiring cosmetic modifications to client sites.
Technical Highlights:
- 16-Watt Audio Projection: Sufficient output for outdoor perimeter communication and indoor facility announcements across typical institutional distances
- Integrated Siren Capability: Combines alarm and voice functions in a single unit, reducing component count and installation labor
- Professional Finish: Matte black construction provides low-profile appearance in security-conscious environments
Deployment Considerations:
- Verify wiring and power specifications with your access control panel or auxiliary relay output before installation
- Position the ER370B with clear sight lines to target audience areas to maximize voice intelligibility and alarm detection
- Test audio output levels during commissioning to ensure coverage across intended deployment zone without over-driving neighboring occupied spaces
The ER370B is a practical choice for integrators who need reliable audio communication and siren functionality without complexity. Speco's established distributor support ensures parts availability and technical guidance throughout the product lifecycle. It's a solid fit for access control, perimeter security, and multi-site notification deployments where straightforward performance is valued over feature proliferation.
