Introduction to the ZXSe System Sensor Loop Driver Card and its key features
Product:ZXSe System Sensor Loop Driver Card (460 mA) — part number 795-068-100. Designed specifically for the ZXSe family of analogue addressable fire panels (ZX1Se, ZX2Se, ZX5Se), this loop driver card adds a single System Sensor protocol addressable loop to a compatible panel chassis. With a 460 mA loop drive rating and very low quiescent current (approximately 12 mA module standby), the card provides a compact, energy-efficient way to expand panel capacity for sites using System Sensor devices.
The ZXSe loop card is a focused accessory: it fits into the ZXSe panel base, uses configurable jumpers to select loop voltage and protocol mapping, and is intended for installations where System Sensor protocol devices are the preferred field hardware. It is not compatible with the ZXe series panels, so choosing the correct panel family is essential.
Detailed specifications and benefits
Understanding the technical details of the ZXSe loop driver card helps installers, system designers, and procurement teams plan projects with confidence. Below are the core specifications and the practical benefits they deliver.
- Part number:795-068-100
- Protocol:System Sensor protocol
- Loop drive current:460 mA (single loop)
- Compatibility:ZXSe family (ZX1Se / ZX2Se / ZX5Se)
- Incompatible with:ZXe series
- Card quiescent current:Approx. 12 mA (module standby)
- Loops per card:1
- Physical dimensions / weight:Insufficient data (refer to panel documentation)
- Datasheet / manual:See ZXSe installation manual and manufacturer product entries for full details
- Protocol compatibility:Native support for System Sensor protocol devices avoids the need for protocol converters or complex mapping, simplifying device integration and commissioning when this device family is already specified for the site.
- 460 mA loop drive:Sufficient for many medium-sized loops, allowing a good number of addressable devices per loop depending on device current consumption. This rating supports a balance between loop capacity and panel power/battery planning.
- Low quiescent draw:The module standby current of roughly 12 mA contributes minimally to the panel’s own standby budget, helping preserve battery life and simplifying auxiliary power calculations.
- Modular expansion:One card per loop model makes panel expansion predictable and straightforward — designers can add loops as needed without replacing the main control unit.
- Fits ZXSe panels:Designed to integrate cleanly into ZX1Se, ZX2Se, and ZX5Se panel bases with jumper-based configuration for quick field setup.
Use cases and scenarios where the ZXSe loop driver excels
The ZXSe System Sensor loop card is aimed at commercial and industrial environments where reliable addressable fire detection is required and System Sensor field devices are already selected or specified. Typical scenarios include:
- Upgrading legacy panels:When expanding an existing ZXSe-based system, adding a loop card lets integrators extend device capacity without swapping the entire panel.
- New-build projects using System Sensor devices:Design teams specifying System Sensor detectors and peripherals can keep a consistent device protocol across the site, simplifying spares, training, and maintenance.
- Medium-sized installations:Sites with several hundred addressable points distributed across zones benefit from a dedicated 460 mA loop per card—enough for many detector and call-point combinations while keeping wiring and device logistics straightforward.
- Mixed device populations (where System Sensor is required for specific areas):If a project needs System Sensor devices in parts of a building and different protocols elsewhere, using specific protocol loop cards keeps segregation clear and manageable.
- Battery and power-constrained projects:The low module standby makes the ZXSe loop card attractive where battery reserve and standby current are design drivers, such as remote sites or installations with limited maintenance access.
Comparisons with similar products on the market
Loop driver cards and interface modules vary by protocol support, loop current capacity, and the number of loops per module. The ZXSe System Sensor loop card occupies a clear niche: single-loop, 460 mA capacity with native System Sensor protocol support for ZXSe panels. When comparing this card to alternatives, consider three principal dimensions:
Some loop driver cards are protocol-agnostic or support multiple protocols via firmware selection, while others are locked to a specific protocol. The ZXSe card is designed for System Sensor protocol devices, which is ideal if that device family is standard on the site. If a project needs multi-protocol flexibility, multi-protocol cards or panels with native support for other popular protocols might be preferable.
Higher-capacity loop cards or those supporting multiple loops (for example, 1 A loop drivers or dual-loop modules) can serve installations with many devices per loop or where devices have higher current draw (e.g., sounder bases, power-hungry peripherals). The ZXSe 460 mA single loop is well-suited to many commercial scenarios but may require more cards or a different approach for very large installations.
The tight integration of ZXSe cards into the ZXSe panel family makes planning and commissioning efficient when that panel is already specified. Other manufacturers’ loop cards may offer different physical form factors, mounting options, or configuration methods that better fit alternative panels or retrofits. Compatibility with existing panels, spare-part strategies, and installer familiarity are important deciding factors.
Customer testimonials and installer feedback
There are no verified public customer testimonials specifically tied to part number 795-068-100 provided here. However, feedback commonly reported by installers and system integrators when working with dedicated protocol loop cards like this one typically highlights several themes:
- Simplicity of integration:Installers appreciate cards that slot into a panel base and use straightforward jumper settings for protocol and voltage mapping—this reduces commissioning time on site.
- Predictable power budgeting:Knowing the loop capacity (460 mA) and low module quiescent draw helps firms model battery and auxiliary power needs accurately, avoiding under-specification.
- Device compatibility:When a project standardises on System Sensor field devices, having native protocol support is reported as a key benefit because it reduces configuration complexity and avoids the need for protocol converters.
If you are seeking verified user reviews, check reseller pages, trade forums, or manufacturer channels where installers publish project notes. For larger deployments, many system integrators maintain internal records of device performance and lessons learned that can inform specification decisions.
Installation guidance, compliance and safety considerations
Installation must always be carried out by a competent technician in accordance with local regulations and the panel manufacturer’s instructions. Key points include:
- Install the loop card into the ZXSe panel base and configure jumpers/links per the ZXSe installation manual.
- Ensure loop wiring, device addressing and termination follow both the panel and System Sensor device manufacturer instructions.
- Factor the card’s quiescent current (~12 mA) and the loop device currents into the panel standby and alarm battery calculations to maintain required autonomy times.
- Confirm approvals and CE/UKCA status from manufacturer documentation before installation to meet local regulatory requirements.
Conclusion: Why choose the ZXSe System Sensor loop driver card?
The ZXSe System Sensor Loop Driver Card (795-068-100) is a focused, efficient solution for expanding ZXSe-series panels with native support for System Sensor protocol devices. Its 460 mA loop drive, very low standby current, and straightforward jumper configuration make it an attractive choice for medium-sized commercial and industrial installations where System Sensor devices are specified.
Choose this card when you need predictable, modular loop expansion, tight integration with ZXSe family panels, and low impact on panel standby power budgets. For sites that require multi-protocol flexibility, higher loop current, or multi-loop modules, evaluate other loop driver options in parallel; but for System Sensor-based systems within the ZXSe family, this card offers a clear balance of compatibility, efficiency, and simplicity.
