Product overview
The CS-154BS is a 15 W wide-range, weatherproof horn (projection) speaker designed for outdoor and indoor paging, background music and tone signalling. It combines a weather-resistant treated cone driver with a constant-directivity horn for clear, highly directional sound and uniform horizontal coverage.

• Power: 15 W rated input via built-in 70.7/100 V multi-tap transformer.
• Coverage: Constant-directivity horn — approx. 90° horizontal coverage.
• Acoustic performance: Frequency response ~150 Hz–15 kHz; sensitivity ~97 dB (1 W/1 m); max SPL ~104 dB (1 m).
• Weatherproof: IP65 splash/dust resistant, operating −20 °C to +55 °C.
• Construction: ABS resin housing with polyurethane paint, stainless steel bracket and aluminium grille (corrosion resistant).
• Compliance: CS-154BS is the voice-alarm / certified variant (EN54‑24 / ISO 7240‑24 / BS‑5839‑8 as listed by the manufacturer).

Use cases: outdoor paging, car-park and perimeter announcements, industrial and commercial site paging, sports grounds, and voice-alarm systems requiring EN54‑24 certification. Suitable for both permanent installations and pro-audio paging systems where directional projection and weather resistance are needed.

Installation & safety notes

• Designed for fixed installation. Installation and wiring should be performed by a qualified installer in accordance with local regulations and voice‑alarm standards.
• Confirm the CS‑154BS certification and required documentation (datasheet / EN54 certificate) with the manufacturer when used in life-safety/voice-alarm systems.
• Observe recommended power taps and impedance matching when connecting to 70/100 V lines to avoid overload.

For full technical drawings, tap tables, and the official EN54 certification documents, refer to the manufacturer datasheet and instruction manual available on the product download pages.
