Tokatuker Horn Strobe Siren For Alarm Systems
This compact siren horn operates on a 12 to 24-volt DC supply and supports three selectable tones to suit different environments. It provides a high-decibel alert—105 dB at 12V and 110 dB at 24V—making it suitable for loud warning in noisy settings. While not UL-rated, it is designed for quick integration with single-action pull stations or whole-system alarms. The device supports straightforward wiring and can be used as a standalone horn or as part of a larger notification network. Consider voltage compatibility with your existing panel and desired tone for clear evacuation cues.

Its compact form helps integrate signaling hardware without dominating wall space.
Buying Guide: Choosing The Right Horn Strobe For Your System
- Voltage and power needs: Most horn strobes run on 12–24V DC. Verify your control panel’s output and ensure the chosen device matches the available voltage and current budget.
- Candela and visibility: Select candela settings that meet your space’s coverage requirements. Higher candela improves visibility in bright environments; lower levels may suffice in smaller or quieter areas.
- Sound levels and tones: Look for multiple tone options (whoop, chime, temporal, etc.) and verify the device meets local accessibility guidelines. Consistency with other devices can simplify testing.
- Standards and compliance: ADA, NFPA, UFC, and local codes influence device selection. Check listed certifications (UL, CSFM, FM, MEA, etc.) and compatibility with existing systems.
- Wiring and installation: Consider back- or front-loading terminals, wire gauge support, and whether prewire or preinstalled modules aid installation. Some models offer synchronization capabilities for unified signaling.
- Indoor vs. outdoor rating: Outdoor-rated units provide weather resistance and rugged construction. Indoor models may suffice for offices or residential spaces but verify environmental ratings.
- Manual call points: If adding manual activation, confirm compatibility with the control panel and the presence of secure latching mechanisms and visibility indicators.
- Maintenance and testing: Prefer devices with test features or voltage verification to simplify routine checks and ensure ongoing reliability during inspections.
- System integration: Evaluate how well a horn strobe coordinates with existing equipment, including pull stations, control panels, and synchronization modules to ensure synchronized alarms.
In summary, the right horn strobe selection balances signaling power, voice alert, installation practicality, and code compliance. The highlighted models span compact residential options to robust commercial configurations, offering varying programming, candela levels, and compatibility to fit a broad range of fire alarm networks.
