Tokatuker Fire Alarm Siren: 12-24V DC Horn Strobe
The Tokatuker horn strobe offers a versatile 12-24V DC operating range and three selectable tones. It produces a loud 105dB at 12V and 110dB at 24V, suitable for alerting occupants in medium to larger spaces. While not UL rated, its compact design makes it a practical option for DIY installations or system integrations where a simple audible/visual alert is required. It supports connection to standard alarm circuits and manual pull stations, enabling quick activation in emergencies.
System Sensor P2RL Horn Strobe
The P2RL horn strobe from System Sensor is designed for plug-in installation with minimal back-box intrusion. It automatically selects 12- or 24-volt operation and offers 15-30 candela options for wall units, with additional field-selectable candela settings (15, 30, 75, 95, 110, 135, 185). This flexibility supports scalable NAC (notification appliance circuit) configurations and easier compliance testing. It’s ideal for retrofit projects where precise flash and sound levels are required for code adherence and occupant safety.
Wheelock MT4-115-WH-VFR Multitone Horn Strobe
The Wheelock MT4-115-WH-VFR is a robust multi-tone horn strobe with a red housing and clear lens. It features a selection of eight signals and a 99dBA sound level, suitable for indoor or outdoor installation in accordance with accessibility and safety guidelines. It supports multiple approvals including UL 1971, CSFM, and MEA, making it a preferred choice for commercial buildings that require verified performance and long-term reliability. Its wiring terminations accept a range of AWG wires, which simplifies integration into existing systems.
Gentex GEC3-24WR Selectable Candela Horn Strobe
The Gentex GEC3-24WR provides selectable candela levels and extensive prewire options, enabling streamlined supervision testing with features like the Checkmate instant voltage verification. It supports low- and high-dBA output modes and frequency ranges, along with a synchronization pathway when paired with Gentex synchronization modules. This horn strobe is designed for installation that requires coordinated alerts across a building, making it suitable for complex commercial systems where consistent signaling is critical.
QWORK: Dual Action Alarm Station with Strobe
QWORK’s wired emergency sound-and-light station combines a 12/24V DC strobe horn with a dual-action manual pull/panic mechanism and two keys. It is designed to work with traditional fire alarm systems to report emergencies. The dual-action pull station provides a visible indication when activated, and the open alarm switch feature helps ensure clear signaling in critical moments. This setup is well-suited for facilities that need a clearly operable manual override alongside audible-visual alerts.
System Sensor P2GRKLED Outdoor Horn Strobe
The P2GRKLED is an outdoor-rated L-Series horn strobe featuring a red housing and robust build suitable for harsh environments. It’s designed for low power consumption with compatibility across legacy System Sensor alerts. It supports both wall and ceiling mounting, delivering a compact yet versatile signaling solution that pairs well with retrofit applications and new installations requiring durable exterior performance.
Buying Guide: Key Purchase Considerations
- Voltage and power: Most horn strobes operate at 12–24V DC. Match the device to your existing fire alarm power supply and ensure your NAC (notification appliance circuit) can sustain the combined load.
- Candela and visibility: Higher candela ratings translate to broader visibility, but may require deeper enclosures and appropriate mounting. Choose candela levels based on room size, ceiling height, and occupant visibility needs.
- Sound level and tones: Look for adjustable dBA levels and multiple tone options to suit different environments and alert protocols. ADA compliance may dictate minimum sound levels for public spaces.
- Compliance and approvals: Verify UL, NFPA, CSFM, MEA, and other relevant certifications. For commercial installations, aligning with local fire codes ensures safer, enforceable testing and maintenance.
- Wiring and compatibility: Check terminal types (AWG compatibility), available back-box space, and whether devices support synchronization with other horn strobes for coordinated signaling.
- Outdoor vs indoor: Use outdoor-rated enclosures and weatherproof models for exterior installations. Ensure IP ratings align with exposure to dust, water, and temperature variations.
- Maintenance and testing: Consider devices with features for easy testing and verification. A good system supports quick voltage checks and straightforward fault isolation to minimize downtime.
- System integration: If you operate a centralized alarm panel, ensure the selected horn strobes integrate smoothly with the panel’s signaling protocol and remote monitoring capabilities.
- Physical installation: Plan mounting options (wall vs ceiling), mounting hardware, and accessible wiring routes. ADA considerations may influence height and reach for pull stations and hoods.
- Budget and reliability: Balance initial costs with long-term reliability, maintenance needs, and the availability of replacement parts or modules across brands.
