System Sensor P2RLED LED Horn Strobe — 1 Each
The P2RLED is a compact LED-based horn strobe designed for areas where bright notification is needed without occupying excessive space. Best for small facilities or retrofit projects requiring visible alerts with minimal footprint. It is listed as manufactured in Mexico, indicating regional production considerations. Consider this model when a compact, LED-first appliance fits your NAC design and budget constraints.
Best for: small to mid-sized spaces seeking high-visibility alerts in a streamlined package. Limitation: the data available emphasizes manufacturing origin rather than detailed electrical specs.
System Sensor P2GRKLED L-Series Outdoor Compact Wall-Mounted Horn Strobe
Designed for outdoor or harsh environments, the P2GRKLED in the L-Series family offers 60% lower average current draw, improving power supply sizing and allowing more devices per NAC. It supports legacy SpectrAlert and L-Series systems, and is common in retrofit projects where continuity with existing installations matters. Dual-listed with UL and ULC certifications, it accommodates red or white lenses for versatile visibility.
Best for: outdoor installations or retrofit projects requiring lower current draw and cross-compatibility with existing System Sensor lines. Caution: ensure compatibility with your specific UL/ULC listing requirements and environmental rating for your site.
System Sensor P2GWKLED Compact Wall-Mounted Horn Strobe
The P2GWKLED delivers a compact wall-mount solution with the same low-current design philosophy as other LED models. It is well-suited for installations where space is at a premium but reliable, high-contrast audible and visible alerts are required. It is compatible with legacy SpectrAlert, SpectrAlert Advance, and L-Series devices to support retrofit projects.
Best for: space-constrained installations and retrofits seeking a uniform L-Series aesthetic with low power draw. Caution: verify that the compact form factor aligns with your mounting plan and clearance requirements.
System Sensor P2RL Horn Strobe
The P2RL provides a practical plug-in design with options for 12- or 24-volt operation and field-selectable candela settings for wall units across several levels. This makes it a versatile choice for various NAC configurations and room layouts. Best used where flexible candela settings help tailor signaling to the space.
Best for: environments requiring adjustable candela settings for on-site tailoring. Limitation: candela options are field-selectable on wall units, which may be less convenient for ceiling-mounted configurations.
System Sensor P4RL 4-Wire, Horn Strobe
The P4RL 4-Wire Horn Strobe is designed to replace P4R in four-wire NAC systems, offering reliable signaling with the familiar System Sensor design language. It is positioned as a straightforward, compatible upgrade or replacement that fits into existing wiring schemes.
Best for: engineers replacing legacy P4R devices or upgrading four-wire NAC installations. Caution: verify four-wire compatibility with your existing NAC and power supply configurations.
Buying Guide
- Environment and rating: Choose outdoor or indoor models based on exposure, moisture, and temperature. Look for compatibility with UL/ULC listings relevant to your site.
- Power and current draw: LED units typically offer lower current draw, which can reduce panel load and permit more devices per NAC. If space or power is limited, favor LED options.
- Installation flexibility: Wall-, ceiling-, and plug-in designs affect mounting ease and retrofit viability. Consider candela settings and field-adjustable options for tailoring alerts to room size.
- Compatibility: If upgrading an existing system, ensure cross-compatibility with SpectrAlert, SpectrAlert Advance, and L-Series devices to maintain a uniform notification strategy.
- Sizing and visibility: Higher candela levels provide stronger visibility in bright or large spaces but may require permissions for nuisance alerts in smaller rooms.
- Maintenance and serviceability: Prefer models with straightforward wiring and plug-in options to minimize downtime during replacements or servicing.
FAQs
- What does “horn strobe” mean in System Sensor devices? It combines an audible horn with a visual strobe to alert occupants in noisy or large spaces.
- Are these devices explosion-proof? The product list includes models designed for harsh environments, with outdoor and rugged options; verify the property of explosion-proof labeling for your specific site before purchase.
- Can I retrofit existing System Sensor networks with these units? Yes, several models are designed for compatibility with legacy SpectrAlert and L-Series systems to ease retrofits.
- Which model is best for low power installations? LED-based horn strobes (P2RLED, P2GRKLED, P2GWKLED) generally offer lower current draw than traditional strobe-only units.
- Do these units require special wiring? Some models are 4-wire compatible, while others operate on 12- or 24-volt configurations; verify your NAC wiring and power supply before installing.
- How do I choose candela settings? Field-selectable candela on wall units helps tailor alert intensity to a given space; plan according to room size and occupancy.
