Product Overview
The ASS73A 110dB 120dB Car Warning Alarm Siren is designed for car security systems, vehicle alarm devices, anti-theft systems, emergency warning equipment, access control alarms, and electronic security products. With 15W, 20W, and 25W power options, this siren provides strong audible warning output for different alarm system requirements.
This car alarm siren supports 1-tone or 6-tone melodic sound output and delivers 110dB, 115dB, or 120dB sound pressure level options at 1 meter. The ABS housing, black appearance, and 73mm compact structure make it suitable for vehicle-mounted and security alarm applications.
With DC 6-15V operation, 4/6/8ohm impedance options, and current ratings of 600/800/1200mA, the ASS73A electronic siren can be integrated into common DC-powered alarm circuits and car security control systems.
Key Features
High sound output options of 110dB, 115dB, and 120dB help provide clear warning signals for car security and alarm applications.
15W, 20W, and 25W power versions support different loudness and installation requirements.
1-tone or 6-tone melodic sound modes allow flexible alarm sound selection for different warning scenarios.
DC 6-15V voltage range supports common low-voltage alarm systems and vehicle security electronics.
ABS housing and black finish provide a practical and durable structure for alarm device integration.
4/6/8ohm impedance options make it easier to match the siren with different alarm control circuits.

Applications
This car warning alarm siren is suitable for car security systems, vehicle anti-theft alarms, motorcycle alarm systems, access control alarms, burglar alarm systems, emergency warning devices, industrial alarm panels, fire alarm accessories, and electronic security products.
It is also suitable for OEM and ODM alarm projects where manufacturers need a compact electronic siren with high sound pressure level, selectable tone options, ABS housing, and DC low-voltage operation.
Working Principle
An electronic car alarm siren converts electrical energy from the alarm control circuit into a loud audible warning signal. When the security system is triggered, the siren produces a high-decibel tone to alert users and deter unauthorized access.
The 1-tone or 6-tone melodic configuration allows the siren to generate different warning patterns, helping users distinguish alarm states or meet specific car security system requirements.
Design and Installation Notes
Install the siren where the sound outlet is not blocked and where wiring can be protected from vibration, moisture, and mechanical damage. The final sound output may vary depending on installation location, enclosure structure, supply voltage, and surrounding acoustic conditions.
For stable performance, ensure that the alarm control system provides sufficient current for the selected power version. Confirm the required power, impedance, sound pressure level, tone option, and voltage range before production or installation.
When used in vehicle security systems, avoid mounting the siren too close to high-heat components or areas exposed to direct mechanical impact.
Why Choose This Car Alarm Siren
The ASS73A car alarm siren combines high sound pressure output, multiple power options, selectable tone modes, ABS housing, and compact 73mm size. It provides a practical warning sound solution for car alarms and security systems.
Its 110/115/120dB SPL options and 15/20/25W power range make it suitable for different alarm loudness requirements, from compact vehicle systems to stronger warning applications.
FAQ
