Strobes & Sirens

Shop strobes and sirens for compatible intrusion alarm and security systems. Find indoor sirens, outdoor alarm sirens, security strobe lights, wireless sirens, sounders, and combination siren-strobe units for residential and commercial security installations. Choose notification devices that match your alarm panel, operating voltage, required sound and visual output, mounting location, and installation requirements.

Security sirens and strobes provide audible or visual notification when a compatible alarm system signals an event. Product features vary by model, so verify electrical ratings, indoor or outdoor suitability, sound output, lens color, tamper protection, and system compatibility before ordering.

Security Sirens & Strobes

Security sirens and strobes are notification devices used with compatible intrusion alarm systems. Sirens produce audible alerts, while strobe lights provide visible flashing signals. Combination devices integrate both functions in one unit.

The right notification device depends on the application, the alarm system's output capabilities, the installation environment, and the required notification method. Check the manufacturer's specifications to ensure that the selected unit is suitable for the intended use.

Intrusion Alarm Sirens

Intrusion alarm sirens generate an audible alert when activated by a compatible security system. Available options may include single-tone and dual-tone sirens, high-output models, self-contained units, and sirens designed for particular alarm platforms.

When selecting an alarm siren, compare sound output, operating voltage, current draw, tone options, mounting method, and compatibility with the control panel or siren driver. Confirm that the alarm system can supply the required electrical load.

Indoor Security Sirens

Indoor security sirens provide audible notification inside a protected building. They are available in different sizes, output levels, housing styles, and installation configurations to suit compatible alarm systems.

Consider the location, required audibility, power requirements, and mounting options when choosing an indoor siren. Review the manufacturer's coverage and installation guidance rather than relying on sound-output ratings alone.

Outdoor Security Sirens

Outdoor security sirens are designed for security installations where an audible alert is required outside a building. Depending on the model, features may include weather-resistant housing, tamper protection, high sound output, and integrated visual signaling.

Verify that the siren is specifically rated for the intended outdoor environment. Check operating temperature, weather resistance, mounting requirements, electrical ratings, and tamper features before installation.

Security Strobe Lights

Security strobe lights provide visual notification by flashing a light when activated by a compatible system. Depending on the product, options may include red, blue, amber, clear, or other lens colors, along with different output levels and mounting styles.

Choose a strobe based on its intended application, power requirements, visibility needs, environmental rating, and compatibility with the connected equipment. Lens color and product approval requirements can vary by use case, so confirm the specifications before purchasing.

Siren & Strobe Combination Units

Siren and strobe combination units combine audible and visual notification in a single device. These products can simplify installations that require both sound and flashing light from a common notification point.

Combination devices vary in sound output, lens color, housing design, power consumption, mounting options, and indoor/outdoor suitability. Confirm whether the unit is self-contained or requires a separate driver or compatible alarm output.

Wireless Security Sirens

Wireless security sirens communicate with compatible wireless alarm systems rather than relying on a dedicated signal cable to the control panel. Some models may include tamper reporting, status indicators, or system-specific communication features.

Wireless sirens are not universally interchangeable. Verify the alarm panel, wireless protocol, supported product family, enrollment requirements, power source, and communication range before purchasing.

Wired Sirens & Sounders

Wired sirens and sounders connect to compatible alarm equipment through a wired output or supported driver. They are available in different electrical configurations and sound-output levels for various intrusion security applications.

Check voltage, current draw, polarity, output type, and any required siren driver or interface. Make sure the alarm panel or power supply supports the selected device's electrical requirements.

Sirens with Tamper Protection

Some security sirens include tamper switches or protective housing features that can help a compatible system identify interference with the device. Other models may offer weather-resistant, impact-resistant, or vandal-resistant construction.

Compare these features according to the installation environment and the requirements of the alarm system. Tamper detection and protective construction vary by model and should be verified in the product documentation.

How to Choose Strobes & Sirens

  • Choose audible, visual, or combined notification: Decide whether the installation requires a siren, strobe, or combination unit.
  • Confirm system compatibility: Match the device to the alarm panel, output, driver, or supported wireless platform.
  • Check operating voltage: Verify voltage, current draw, and power-supply capacity.
  • Compare sound output: Review the specified sound level and tone options for the intended application.
  • Review the strobe: Check lens color, visual output, and installation requirements.
  • Choose indoor or outdoor equipment: Confirm the product's environmental rating and mounting requirements.
  • Consider tamper protection: Select the features needed for the installation and supported by the system.
  • Check installation dimensions: Verify the housing size, mounting method, and cable-entry requirements.
  • Confirm the intended application: Ensure that the product is designed for the security notification function required.

Security Sirens for Residential & Commercial Applications

Security sirens and strobes are used in residential alarm installations, commercial buildings, offices, and other environments where compatible intrusion systems require audible or visual notification. The correct product depends on the alarm system, location, desired output, and environmental conditions.

For professional installations, review the system design, power budget, output specifications, mounting instructions, and manufacturer compatibility information before selecting a device.

Important: Security Strobes vs. Fire Alarm Notification Devices

Security strobes and sirens are not automatically suitable substitutes for listed fire alarm notification appliances. Fire alarm systems may require specific listed and compatible horns, strobes, horn-strobes, or other notification devices under the applicable system design and codes.

If the intended application is fire alarm notification, select products specifically approved for that fire alarm system and application. Review the relevant manufacturer documentation and applicable local requirements.

Frequently Asked Questions About Strobes & Sirens

What is the difference between a siren and a strobe?

A siren produces an audible alert, while a strobe provides a flashing visual signal. A combination unit integrates both functions in one device.

Can I use any siren with my alarm panel?

No. Compatibility depends on the panel's output, operating voltage, current capacity, wiring, and any required driver or interface. Always check the manufacturer's specifications.

Are wireless sirens compatible with all wireless alarm systems?

No. Wireless sirens commonly use system-specific communication protocols. Confirm compatibility with the exact alarm panel and supported wireless product family.

Can an outdoor siren be installed indoors?

Some outdoor-rated models may be suitable for indoor use, but this depends on the manufacturer's instructions and the installation requirements. Verify the approved mounting locations and operating conditions.

What should I check when replacing a siren or strobe?

Identify the existing model and confirm operating voltage, current draw, sound or visual output, mounting dimensions, wiring, and compatibility with the connected alarm equipment.

Are security strobes suitable for fire alarm systems?

Not necessarily. Fire alarm notification requires devices specifically listed and compatible with the fire alarm system and intended application. Do not assume a security strobe meets those requirements.
