Quam UL22/70 Ceiling Mountable Speaker — 20 W RMS

The Quam UL22/70 Ceiling Mountable Speaker is engineered for modern buildings that demand reliable, high-visibility signaling with superior audio performance. This UL Listed ceiling speaker combines a shallow, tile-replacement design with fire-protective components, delivering crystal-clear voice announcements and alert tones across 70V distribution. Built to meet stringent safety standards (UL 1480-F and UL 2043), it integrates seamlessly into ceilings while maintaining a discreet profile, making it ideal for educational facilities, offices, hotels, airports, and commercial spaces where audible alerts and paging matter as much as architectural aesthetics.

• UL Listed protection and fire safety integration: The UL22/70 is listed under UL 1480-F and UL 2043, ensuring it meets critical fire-safety and signaling standards. Its fire-retardant components and integrated enclosure are designed to function reliably in life-safety signaling environments, giving building operators confidence during emergencies while preserving ceiling aesthetics.
• Low-profile, tile-replacement design with strong acoustics: This shallow-depth speaker is purpose-built for tile-in installations, minimizing intrusion into ceiling plenum spaces. Despite its compact form, it houses a robust 8" (8C10PAFR) loudspeaker capable of delivering clear, intelligible announcements and reliable background sound, even in challenging architectural environments. The 10 oz magnet supports efficient, high-fidelity reproduction without adding bulk to the ceiling.
• 80-watt-class capability with 20 W RMS handling: The UL22/70 is engineered to deliver up to 20 W RMS of continuous audio power on a 70V distribution line, providing strong projection and intelligibility across large spaces. Its integrated 4W-70V rotary transformer enables precise taps for scalable signaling and paging installations, allowing system designers to optimize volume levels for different zones or rooms.
• 70V compatible, rotary transformer for flexible installation: The included rotary transformer supports multiple 70V taps, enabling easy adaptation to common centralized paging and alert systems. This feature makes it straightforward to blend the speaker into existing networks, whether for daytime paging, emergency voice evacuation, or routine announcements, while preserving consistent sound levels throughout the facility.
• Integrated enclosure and durable construction for long-term reliability: The enclosure is molded and designed to be part of a fire-rated signaling device, with an integral 1,412 CID molded enclosure that contributes to both acoustic performance and structural integrity. The combination of a rigid enclosure, fire-retardant components, and a lightweight frame yields a product that stands up to daily use in busy commercial environments while maintaining a minimal footprint in the ceiling.

How to Install Quam UL22/70 Ceiling Mountable Speaker

• Plan the installation in accordance with local codes and the building’s fire-safety signaling design. Verify that the space supports a 70V signaling system and that the UL22/70 is appropriate for the intended purpose.
• Prepare the ceiling by selecting a suitable tile opening. The UL22/70 is designed for tile replacement installations; ensure the tile cutout matches the enclosure dimensions for a secure, flush fit.
• Mount the enclosure in the ceiling with appropriate hardware, ensuring the housing is securely fastened and aligned with the ceiling grid. Confirm that the mounting surface provides adequate support for the weight and installation environment.
• Connect the 70V distribution wiring to the 4W-70V rotary transformer on the speaker. Observe correct polarity and use appropriate wiring practices to maintain signal integrity and prevent noise or phase issues in the network.
• Attach the speaker assembly to the enclosure, seal any joints as needed, and reinsert the ceiling tile. Power up the system and perform a test transmission to verify intelligibility, level consistency across zones, and proper triggering of any signaling features.
• Fine-tune the taps on the rotary transformer to achieve the desired level in each zone. If multiple speakers exist within a network, coordinate volume levels to ensure even coverage without distortion or clipping.
• Document the installation for maintenance and inspections, including the exact transformer taps used and any configuration notes. Regular system testing during routine maintenance helps ensure ongoing reliability in life-safety signaling scenarios.
• Follow safety guidelines throughout installation, including de-energizing circuits during wiring tasks and adhering to fire-safety and electrical codes applicable to your jurisdiction.
