Klaxon PNC-0009 Nexus 120 Sounder Red 5J Xenon Beacon 110/230V AC

Klaxon PNC-0009 Nexus 120 High-Output Sounder with 5J Xenon Beacon (110/230V AC)

The Klaxon PNC-0009 (Manufacturer Legacy Reference: 18-980552) is an industrial-grade, combined audio-visual signaling device. It delivers an acoustic profile of up to 120 dB(A) at 1 meter coupled with a high-intensity 5 Joule red pulsed xenon flash discharge.

Engineered for environments characterized by high ambient machinery noise—such as shipboard engine rooms, processing facilities, bulk material handling plants, and offshore platforms—the PNC-0009 utilizes a two-piece architectural configuration.

The base unit acts as a dedicated mounting backbox containing internal termination blocks. This design isolates all field cabling within the enclosure base before the active transducer head is locked into place using captive quarter-turn fasteners.

Technical Details

Key Features

1. High Acoustic Penetration (120 dB(A)): High-output transducer delivers up to 120 dB(A) at 1 meter with continuous 20 dB potentiometer volume attenuation.
2. High-Yield 5J Xenon Flashtube: Emits a distinct 1 Hz pulsed visual flash (60 flashes/min) through a red fresnel optic.
3. Two-Piece First-Fix Architecture: Base-mounted wiring terminals eliminate wire-strain on the active acoustic/optic head, securing environmental integrity via four 1/4-turn fasteners.
4. Independent Circuit Terminals: Dedicated neutral and hot terminations allow asynchronous or linked triggering of the sounder and beacon circuits.
5. Standard 3-Stage Remote Tone Switching: Onboard 6-way DIP switches grant selection of 64 standardized alert, evacuation, and emergency warning profiles.

Applications

• Marine Machinery Spaces: Main engine rooms, auxiliary generator flats, steering gear compartments, and separator rooms where background acoustic levels exceed 95 dB(A).
• Vessel Safety Systems: Integrated with general emergency alarms, CO₂/halon pre-discharge release indicators, water mist deployment alarms, and cargo pump room safety panels.
• Offshore Oil & Gas Installations: Process module deck signaling, gas detection annunciation, crane movement zone perimeter warnings, and marine muster station staging points.
• Heavy Manufacturing Plants: Metal stamping plants, steel foundries, automated robotic workcells, and high-traffic gantry crane transit alleys.
• Hazardous Fluid & Chemical Storage: Sump level alarms, chemical loading/unloading terminals, emergency eye-wash/shower active warnings, and vapor extraction plant failure alerts.

Frequently Asked Questions

Can the sounder and beacon on the PNC-0009 be operated independently?

Yes. The PNC-0009 features completely split internal AC power rail terminals for both the sounder section and the xenon flashtube. You can power the beacon continuously for visual notification and energize the sounder only during critical alarm conditions, or wire their matching voltage terminals in parallel for simultaneous triggering.

How do I switch the operating voltage between 110V AC and 230V AC?

Voltage selection is determined by physical wire allocation on the terminal blocks. There is no internal transformer switch or jumper link to move. Connect your active supply lead to the “110V” terminal for 110V AC supplies, or to the “230V” terminal for 230V AC circuits, and secure the common lead into the “Neutral” port.

Can I adjust the sound volume if 120 dB(A) is too loud for smaller technical spaces?

Yes. An onboard potentiometer provides up to 20 dB(A) of continuous acoustic attenuation. You can reduce the sound output down to approximately 100 dB(A) to avoid permanent acoustic hearing risk inside compact spaces such as emergency generator lockers or pump rooms.

What is the service life of the 5-Joule xenon tube?

Under continuous emergency operation at 60 flashes per minute, a 5-Joule xenon tube is rated for roughly 5 to 8 million discharges before light output drops to 70% of initial output. In standard intermittent marine/industrial emergency service, the tube will typically operate for several years without replacement.

Is the Klaxon PNC-0009 suitable for hazardous ATEX / Zone 1 locations?

No. The PNC-0009 is an industrial and marine IP66 weatherproof sounder beacon. It is not explosion-proof or flameproof. For hazardous areas requiring Zone 1, 2, 21, or 22 compliance, an ATEX/IECEx certified model such as the Klaxon BEx or similar Ex-d rated sounder must be specified.
