Lifesafety Power AC-CABLE-18-BOXED-SET-OF-2 AC Power Cable Harness
Overview
The Lifesafety Power AC-CABLE-18-BOXED-SET-OF-2 is an 18-inch AC power cable harness sold as a matched pair, designed specifically for Lifesafety Power FPO series power supplies. This two-pack addresses a practical integrator need: having spare or replacement AC harnesses staged during commissioning, cabinet builds, or field service calls eliminates project delays when an existing harness fails or a second unit gets deployed mid-site. The 18-inch length is routed standard in surveillance cabinet layouts — it reaches from typical mains entry points to the FPO unit's AC input receptacle without requiring intermediate extension cables, which saves cost and reduces failure points.
Key Features
- 18-Inch Length: Fits standard 19-inch and 23-inch rack cabinet runs from AC mains panel to power supply mounting location. Eliminates need for extension cables or splitters, reducing complexity and potential intermittent connection issues during vibration or thermal cycling.
- FPO Series Compatibility: Engineered connector pinout and voltage class match Lifesafety Power FPO units. Verify your FPO model documentation before installation — connector polarity and AC voltage specification must align with your specific unit.
- Two-Pack Quantity: Each box contains two cable harnesses. Useful for redundancy in a single cabinet, or staging spares across multiple sites to avoid service call delays when a primary cable needs replacement.
- AC Mains Input: Accepts standard AC mains voltage per the FPO unit's input specification. Always verify mains voltage at the cabinet inlet matches the power supply's rated input before energizing.
- EMI Mitigation: Route away from video and data cabling where practical to minimize conducted electromagnetic interference, which can introduce noise in sensitive video circuits or corrupt digital signals in nearby ethernet runs.
- Compact Storage: Individual cable harnesses ship boxed, enabling technicians to keep spare units in a service van or on-site storage without tangling or environmental exposure.
Integration and Installation
The AC-CABLE-18-BOXED-SET-OF-2 is a passive component — it carries AC mains directly from the facility inlet to the FPO power supply. No configuration or software is required. Physically, secure excess cable using adhesive-backed hook-and-loop straps or cable clips; do not coil tightly or bend sharply at the connectors, as repeated mechanical stress can fracture internal conductors or loosen crimped connections. If deploying multiple FPO units in a single cabinet, stagger cable entry points to avoid mechanical load concentration on the cabinet frame or strain relief boots. Before energizing, confirm AC input voltage matches the FPO unit's specification — mismatched voltage can cause component failure or fire hazard. Consult your Lifesafety Power power supply documentation or speak with a systems integrator if you need guidance on sizing multiple units or planning redundancy.

Frequently Asked Questions
Q: Can I use the AC-CABLE-18-BOXED-SET-OF-2 with non-FPO Lifesafety Power supplies?
A: No. This harness is engineered for FPO series units only. Connector pinout and voltage class are specific to that family. Using it with other power supply models may result in improper mating, loose connections, or unsafe voltage mismatches. Always confirm connector compatibility in your power supply documentation before installation.
Q: What AC input voltage does this cable support?
A: The cable itself is passive and voltage-agnostic — it carries whatever AC input your facility provides. Your FPO power supply unit will have a specified input voltage (typically 110–240V AC). Match that specification, not the cable.
Q: Is the 18-inch length sufficient for my cabinet layout?
A: Eighteen inches is standard for typical 19-inch and 23-inch rack cabinet runs from a mains entry panel to a power supply mounted on a rail or bracket. If your mains inlet is farther than 18 inches from the FPO unit, you'll need an intermediate extension cable or a different routing plan. Measure before ordering.
Q: Can I replace a damaged AC-CABLE-18-BOXED-SET-OF-2 harness in the field?
A: Yes, it is a field-replaceable component. De-energize the cabinet at the main breaker, disconnect the failed harness from both the AC inlet and the FPO unit, and install the spare using the same routing and strain relief method. Do not operate the cabinet with a loose or partially connected harness.
Q: What's the warranty on the AC-CABLE-18-BOXED-SET-OF-2?
A: Consult Lifesafety Power or the product documentation for warranty terms. Cables are typically covered under manufacturer defect warranties, but physical damage or misuse may not be included.
The AC-CABLE-18-BOXED-SET-OF-2 is a workhorse accessory that solves a common field problem: when you're building out a multi-unit power architecture and a cable fails or gets pinched during cabinet assembly, having spares on-site keeps the timeline moving. The 18-inch length is exactly right for standard surveillance racks — it eliminates the temptation to jury-rig extensions or run undersized feeders, both of which introduce failure modes. This is the kind of component you buy in bulk and forget about until you need it.
Technical Highlights:
- 18-Inch Length: Spans typical cabinet mains entry to FPO unit mounting location without extension cables, eliminating loose connections and reducing EMI coupling paths into video and data circuits.
- FPO Series Pinout: Connector geometry and polarity are specific to Lifesafety Power FPO supplies. Mismatched connectors will not mate safely — this is not a generic AC cable, and that specificity prevents accidental cross-wiring.
- Two-Pack Economics: Buying two harnesses at once is cheaper per unit than reordering one-off during an emergency service call. Stash one on-site and one in your van.
Deployment Considerations:
- Route this cable away from video/data runs — AC mains can radiate 50–60 Hz interference into unshielded twisted-pair or composite cabling, degrading image quality or introducing digital errors.
- Always verify the AC mains voltage at your facility matches the FPO unit's input spec (typically 110–240V) before plugging in. Voltage mismatch can destroy the supply's input stage.
- Secure excess cable with adhesive hook-and-loop straps, not tight coils. Repeated flexing or sharp bends at the connectors will fatigue the internal conductors, leading to intermittent dropout.
The AC-CABLE-18-BOXED-SET-OF-2 is essential sparing inventory for any integrator deploying multiple FPO units across a surveillance cabinet or a multi-site rollout. It's simple, field-proven, and cheaper to have on-hand than to be caught without one during a service call or cabinet refresh.
