Introduction: Apollo 45681-284APO XPERT 7 Isolating Detector Base
Product:Apollo 45681-284APO XPERT 7 Isolating Base (for XP95/Discovery detectors). This addressable detector mounting base adds robust short-circuit isolation to fire-alarm loops and spurs while keeping installation and maintenance simple. Designed for use with Apollo XP95 and Discovery detector families, the XPERT 7 base combines a high-brightness LED, low-insertion-force contacts, locking provision and XPERT addressing support to streamline device commissioning and minimise system disruption.

- Compatible with Apollo XP95 and Discovery addressable detectors
- Approved to multiple standards (CPR, FG, LPCB, VdS as listed by the manufacturer)
Detailed specifications and benefits
The Apollo XPERT 7 isolating base is engineered with practical installation and system resilience in mind. Key technical specifications include a 100 mm diameter and 24 mm depth, making it a space-efficient choice for most ceiling and wall-mounted detector positions. The housing is manufactured from self-extinguishing polycarbonate and uses nickel-plated stainless-steel terminals to ensure long-term conductivity and resistance to corrosion. The base supports the typical XP95/Discovery loop supply voltage range (17–28 V dc) and can be used where multiple devices are monitored between isolating bases (manufacturer guidance allows up to 20 detectors or equivalent loads between isolators).
Primary benefits arising from these specifications:
- Rapid fault containment:The built-in isolator detects and automatically isolates short-circuits. When a short occurs, only the affected segment is isolated rather than the entire loop, maintaining protection for the rest of the system and reducing false alarms or total loop loss.
- Clear visual status:The high-brightness LED indicator provides instant confirmation of device health and isolator status, aiding routine inspection and troubleshooting without the need for additional tools.
- Durable connections:Low insertion force and nickel-plated stainless-steel contacts make detector insertion and removal easier while ensuring reliable electrical contact over time — important in high-vibration or high-use environments.
- Secure installations:The locking provision helps prevent accidental or unauthorised detector removal — useful in public or high-security buildings.
- Efficient commissioning:XPERT addressing support (XPERT card supplied) simplifies device numbering and addressing during installation, saving time for contractors and reducing human error.
- Compliance-ready:Approvals such as CPR, FG, LPCB and VdS (as listed by Apollo) mean the base meets widely recognised standards for performance and safety in fire-detection systems.
- Weight: light and manageable (approx. 52–100 g depending on packaging), simplifying handling during installation.
- Material choice: self-extinguishing polycarbonate helps limit the bases contribution to fire load and meets common safety requirements.
- Warranty: manufacturer-backed 10-year warranty gives installers and building owners confidence in product longevity.
Use cases and scenarios where the XPERT 7 excels
The isolating base is particularly valuable where loop integrity and continuous protection are critical. Typical applications include:
- Commercial office buildings:Preventing a single wiring fault from taking multiple floors or zones offline keeps business continuity and occupant safety intact.
- Industrial facilities and manufacturing sites:Environments with a higher risk of wiring damage or electrical noise benefit from isolation to limit the impact of faults.
- Hospitals and healthcare facilities:Where alarms must remain operational to protect vulnerable patients, isolating bases reduce the risk of widespread service loss.
- Data centres and critical infrastructure:Any interruption can be costly; isolating faults quickly is essential to maintain protection without triggering mass evacuations or shutdowns.
- Retrofit projects:When adding addressable systems to older wiring or complex runs with spurs, isolators make it easier to segment and protect uncertain cable conditions.
- High-traffic public spaces:Locking provision prevents tampering or accidental removal in venues such as schools, shopping centres, hotels and transport hubs.
Comparisons with similar products
When selecting a detector base, installers typically choose between standard non-isolating bases, isolating bases, and specialised bases with features like remote LED or integral sounders. The XPERT 7 sits firmly in the isolating base category but offers a few advantages that make it stand out:
- Versus non-isolating XP95/Discovery bases:Non-isolating bases are simpler and often cheaper upfront but leave the entire loop vulnerable to a single fault. The XPERT 7s isolator reduces the risk of total loop failure and the associated downtime — a strong benefit where continuity matters.
- Versus alternative isolating bases:Many isolating bases provide isolation but may lack XPERT addressing support or a high-visibility LED. The XPERT 7 combines automatic isolation with commissioning conveniences (XPERT card) and a bright status LED, speeding installation and routine checks.
- Versus integrated sounder bases or remote indicator bases:Those options add functionality (audible or remote visual signals) but also complexity and cost. For projects primarily focused on reliability and fault isolation, the XPERT 7 offers a balanced, cost-effective solution without unnecessary extras.
In short, if your priority is maintaining loop integrity and simplifying maintenance while staying compatible with Apollo XP95 and Discovery detectors, the XPERT 7 represents a compelling middle ground between basic bases and feature-heavy specialised units.
Customer feedback and representative testimonials
Direct customer reviews for specific part numbers may be limited in public forums, but typical feedback themes from electrical contractors and fire-system installers using isolating bases like the XPERT 7 include:
- "Installation time reduced — the XPERT addressing card makes numbering quick and accurate, cutting commissioning time."
- "When a short occurred in a storage area, the isolator saved the rest of the loop — we repaired the fault without evacuating the whole building."
- "The LED is bright and easy to see during site checks, which helps our maintenance team identify issues quickly."
These representative comments reflect common installer experiences: faster commissioning, simpler troubleshooting and reduced operational disruption. When evaluating products, request site-specific references from suppliers if you need real-world case studies tied to your sector.
Conclusion: Why choose the Apollo 45681-284APO XPERT 7
The Apollo XPERT 7 isolating detector base delivers a pragmatic blend of reliability, installer-friendly features and industry approvals.
