Specs
Technical specifications.
| Spec | Senstar FiberPatrol FP1150 | GS-20 Underground Sensor |
|---|---|---|
| Sensor type | Ranging fiber-optic intrusion detection - fence-mounted, buried, or wall-top deployment; also protects buried pipelines and data conduits (TPI) | — |
| Max perimeter per processor | Up to 80 km | — |
| Localisation accuracy | +/-4 m | — |
| Detection principle | Laser pulse reflectometry in single-mode fiber: measures minute light reflections along the cable; fence vibration changes returned light at that point | — |
| Multiple simultaneous intrusions | Accurately detected and located | — |
| Alarm reporting | By zone number, cable distance and/or GPS coordinates; flexible software-based zoning | — |
| Cut immunity | Cable cut immediately reported with exact location; detection continues up to the cut point; full cut-immune configuration keeps detection on the entire perimeter after a cut | — |
| Redundancy | Redundant configuration with automatic failover transparent to the alarm system; redundant hot-swappable power supplies and SSDs per sensor unit | — |
| Sensor medium | Single-mode fiber within telecommunications-grade cable; 25+ year nominal service life; unused fibers reusable for networking/other devices; LSZH, fire-retardant and fire-resistant cable ratings possible | — |
| Field power | No powered or conductive items required in the field; immune to EMI and lightning; intrinsically safe in explosive atmospheres | — |
| Nuisance alarm mitigation | EDAPT adaptive processing for sustained environmental noise plus environmental disaggregation via precise ranging (randomly distributed in-zone disturbances do not alarm) | — |
| Fence compatibility | Chain-link, welded mesh and expanded metal mesh; single cable pass protects fences up to 4.3 m high; palisade depending on fence characteristics; wall-top mounting on one or both corners of walls | — |
| Buried mode | Detects characteristic vibrations of walking, running or crawling intruders above a buried sensor cable | — |
| Gate protection | Cable installable on swinging gates as an independent zone; sliding gates via Wireless Gate Sensor or UltraWave | — |
| Processor format | Integrated 4U sensor unit with all detection and gateway software built in - no separate integration server; built-in alarm display application; Windows OS with familiar GUI for local and remote management | — |
| Communications / I/O | Built-in Ethernet; supports Senstar UltraLink family of I/O cards; output-relay integrations supported | — |
| Integration | Network Manager to Senstar Symphony Common Operating Platform and third-party VMS/security/PSIM systems; free SDK | — |
| Certification | UK NPSA certified against version 6.0 of the NPSA Barrier Mounted PIDS Standard | — |
| Sensing modalities | — | Internal seismic (pedestrian) + internal magnetometer (vehicle presence and travel direction) |
| External sensor inputs | — | PIR and contact-closure via configurable external connector |
| Sensor fusion | — | Up to 5 sensors |
| Radio | — | Built-in 5 W VHF, programmable RF output power, strong foliage penetration |
| Radio range | — | Up to 35 miles line-of-sight |
| Alarm codes | — | Up to 15 unique |
| Sensor address range | — | 1-9999 |
| Power | — | 8-20 VDC |
| Battery life | — | 1+ year (deployment 3 months to 1 year or longer depending on configuration) |
| Dimensions | — | 6.5 x 3 x 3 in |
| Enclosure | — | Watertight, corrosion-proof fiberglass-reinforced polyester with silicone foam gasket |
| Deployment | — | Buried (antenna only above ground) or above-ground |
| Output | — | Mechanical relay to trigger external devices (cameras, lights, sirens) |
| Security | — | Internal tamper switch |
| Timing | — | Real-time clock; programmable self-test messages and scheduled access windows |
| Networking | — | Stand-alone or networked; Coyote/Cub relay mode; compatible with legacy Vortex and Monitron systems |
