System Sensor P2RL Horn Strobe
The P2RL model is designed for minimal intrusion into back boxes with a plug-in design. It automatically selects 12- or 24-volt operation at 15 and 30 candela. Wall units offer field-selectable candela settings at 15, 30, 75, 95, 110, 135, and 185. These features support flexible installation in diverse NAC configurations. The unit emphasizes compatibility with System Sensor’s broader ecosystem and reliable audible-visual signaling for life-safety applications.
System Sensor P2RL Horn Strobe Variant
The P2RL family emphasizes a compact plug-in form that reduces back-box intrusion. Automatic candela selection adapts to voltage while backbox space is preserved. The device is part of a scalable architecture that can support various fire alarm systems by providing consistent visual alerts and synchronized performance with other horn-strobe devices.
System Sensor P2RLED L-Series Indoor 2-Wire LED Horn Strobe
LED-based horn strobes deliver lower current draw, helping extend NAC capacity and reducing energy consumption. The P2RLED provides digital voltage meter (DVM) diagnostic test points for horn strobes and maintains a consistent L-Series visual language across the platform for easier maintenance and replacement in retrofits.
System Sensor SRL Red Fire Strobe
The SRL Red Fire Strobe represents a straightforward, purpose-built notification appliance with a strong red strobe signal. This model is aligned with System Sensor’s legacy SRL line, offering dependable visual alerts for fire alarm circuits and consistent performance with compatible devices in the same family.
System Sensor PC2RLED L-Series 2-Wire LED Horn Strobe
This PC2RLED model combines LED efficiency with L-Series aesthetics. It includes 2-wire operation and compatibility with legacy SpectrAlert, SpectrAlert Advance, and L-Series devices. Digital diagnostics and uniform appearance across the series improve diagnostic workflows and retrofit viability in multi-brand or legacy installations.
System Sensor P2WLED LED Horn Strobe 2-Wire White
The P2WLED 2-Wire White horn strobe emphasizes LED signaling in a compact footprint. Made in Mexico, it aligns with System Sensor’s manufacturing footprint while offering dependable performance for white-finished installations, maintaining visual uniformity with other L-Series devices.
System Sensor PC2WLED L-Series 2-Wire LED Horn Strobe
The PC2WLED is designed for two-wire installation with LED signaling. It is compatible with legacy SpectrAlert, SpectrAlert Advance, and L-Series devices, ensuring cohesive performance across an installed base. This option supports ceiling-mount configurations and a white finish suitable for many interiors.
System Sensor P2GRKLED L-Series Outdoor Horn Strobe
The P2GRKLED is designed for outdoor or harsh environments with a rugged exterior. It features compatibility with L-Series family components and supports red or white color options. The unit’s dual-listed UL/ULC certifications reflect its suitability for diverse building codes and retrofit projects in exterior-facing installations.
Buying Guide
Key considerations when selecting a System Sensor horn strobe:
- Voltage and current: Verify compatible voltages (12V, 24V) and current draw, especially for LED models that reduce power use and extend NAC capacity.
- Candela settings: Choose devices with adjustable candela to match room size, occupancy, and echo requirements.
- Indoor vs. outdoor use: Outdoor-rated options provide weather resistance and reliability in exposed installations.
- Wiring and compatibility: Ensure two-wire or more complex wiring aligns with existing fire alarm panels and legacy devices (SpectrAlert or L-Series).
- Diagnostics: LED-based models with digital voltage meters (DVM) simplify maintenance and fault isolation.
- Aesthetics and finish: Finish colors (white or red) and housing design should align with building interiors and color schemes.
- Maintenance and retrofits: Choose models with common aesthetics across the L-Series family for easier replacement and upgrades.
- Certification and compliance: Confirm UL/ULC certifications and compatibility with your system’s notification strategy and local codes.
Across the listed options, LED-based units typically offer lower power usage and diagnostic features, while standard SRL-style strobes provide straightforward signaling. When retrofitting, prioritize models with backward compatibility to minimize wiring changes and ensure consistent visual signaling across all notification appliances in the system.
