Honeywell PA System
Model No. L-PBM20A
It's a high-performance 20 Watt loudspeaker designed for public address and voice alarm (PAVA) systems.
Bidirectional: This is a key feature. Unlike typical speakers that project sound in one primary direction, a bidirectional speaker projects sound in two opposite directions (e.g., along a corridor or tunnel). This makes them highly efficient for covering long, narrow spaces.
Projection Loudspeaker: This term generally refers to speakers designed to "project" sound over a distance, often with a more focused dispersion than a standard ceiling or wall speaker. They usually have a cylindrical or bullet-like shape.
Key Features and Specifications (L-PBM20A):
Manufacturer: Honeywell (and sometimes re-branded or compatible versions from other manufacturers).
Rated Power: 20 W (often stated as 10W x 2, implying two speaker drivers inside, each contributing 10W).
Max Power: 30 W.
Power Taps: Designed for 70V/100V line public address systems, it has multiple power taps (e.g., 20 W, 10 W, 5 W, 2.5 W) allowing installers to adjust the output volume based on the specific zone requirements.
Frequency Response: Typically in the range of 150 Hz to 15 kHz or 20 kHz, ensuring good clarity for both voice announcements and background music.
Sound Pressure Level (SPL): High SPL for effective broadcasting, often around 104 dB to 107 dB at max power (1 meter).
Dispersion Angle: 180° at 1 kHz (-6 dB), which is characteristic of its bidirectional nature.
Construction:
Material: Usually made from aluminum (enclosure, front cover, bracket), making it durable, corrosion-proof, and suitable for various environments.
Color: Often White (RAL9003) to blend with most ceilings or walls.
Speaker Size: Typically includes two 5.25" drivers.
Environmental Ratings:
IP65 certified: This means it's highly protected against dust ingress and resistant to low-pressure water jets, making it suitable for both indoor and outdoor (dry or wet) applications.
Temperature Range: Wide operating temperature range, commonly from -25°C to +55°C.
Humidity: Less than 95% relative humidity (non-condensing).
Fire Safety Features:
Fire-resistant cable connector (high-temperature ceramic): This is crucial for emergency evacuation systems, as it ensures the speaker remains operational and can broadcast messages even during a fire, protecting internal components from heat.
Temperature fuse: Protects the speaker from overheating due to improper loading.
Compliance: Often complies with international safety standards like EN54-24 (for Voice Alarm loudspeakers), UL60065, and RoHS.
Common Applications:
Bidirectional projection loudspeakers like the L-PBM20A are ideal for:
Tunnels: To ensure clear communication along the entire length.
Corridors and Hallways: In large buildings, shopping malls, schools, hotels, and offices.
Galleries: In museums or art galleries for announcements or background audio.
Shopping Arcades: For public announcements, promotions, or background music.
Railway Stations and Airports: For passenger announcements and emergency broadcasts.
Warehouses and Factories: For paging and safety messages.
Parking Garages: For clear communication to drivers and pedestrians.
In essence, the Honeywell L-PBM20A is a robust, high-performance, and fire-compliant loudspeaker designed to provide clear, intelligible audio in challenging long and narrow environments, especially critical for emergency evacuation systems.
