FAQs

What is the advantage of the dual bus architecture in the 200WE?

The 200WE features a dual bus architecture that provides exceptional system reliability and flexibility. Unlike single bus systems, the dual bus configuration allows the system to maintain partial operation even if one bus experiences issues, ensuring continued security coverage. This architecture also distributes the electrical load more efficiently across two buses, supporting the large number of devices required for 200-zone installations. The dual bus system is particularly valuable in larger premises where bus cable runs are extensive, as it reduces signal degradation and maintains robust communication with all connected devices.

Can the 200WE be certified as both Grade 2 and Grade 3?

Yes, the 200WE can be configured and certified as either EN50131 Grade 2 or Grade 3, depending on the security requirements of the installation. Grade 3 certification requires additional security measures and is typically specified for higher-risk applications such as jewelry stores, banks, or facilities with valuable assets. The ability to achieve either grade makes the 200WE versatile for various security specifications without requiring different hardware. The installer configures the system to meet the specific grade requirements during commissioning, including appropriate tamper protection, signaling methods, and user access controls.

How does hybrid expansion work with both wired and wireless zones?

The 200WE’s hybrid expansion system allows installers to use a combination of wired and wireless zone expanders to reach the 200-zone capacity. This provides maximum installation flexibility, as wired expanders can be used in areas with easy cable access or where maximum reliability is required, while wireless expanders are ideal for difficult-to-wire locations, historic buildings, or retrofit installations. The system seamlessly integrates both types of expanders on the bus, treating all zones consistently regardless of their connection method. This hybrid approach optimizes installation costs and time while maintaining comprehensive security coverage.

What are shunt groups and how are 10 groups used in larger installations?

Shunt groups are pre-configured sets of zones that can be bypassed (shunted) together with a single command, typically used for part-setting the system. The 200WE’s 10 shunt groups provide exceptional flexibility for complex installations such as multi-tenant buildings, industrial facilities with multiple departments, or large commercial properties with different operational areas. For example, in a shopping center, each retail unit could be assigned to different shunt groups, allowing individual stores to arm/disarm independently while maintaining common area protection. This level of granular control significantly enhances the system’s usability in sophisticated applications.

Why does the 200WE have so many output types and what are they used for?

The 200WE provides three categories of outputs for different purposes: 4 on-board panel outputs for direct high-current device control (such as door strikes or relay-activated equipment), 16 plug-by outputs specifically designed for communicator modules and low-current signaling devices, and 20 custom outputs that can be programmed for various automation and integration functions. This extensive output configuration enables comprehensive building integration, allowing the alarm system to control lighting, HVAC, access control systems, CCTV equipment, and other building management functions based on alarm events, user commands, or schedules. The large number of outputs makes the 200WE suitable for sophisticated installations requiring extensive system integration.

What is the significance of the 17Ah backup battery capacity?

The 200WE’s support for backup batteries up to 17Ah is significantly higher than smaller control panels, providing extended operation during mains power failures. This is critical for large installations with many powered devices such as multiple keypads, expanders, wireless receivers, and other bus devices. The 2.0A power supply combined with large battery capacity ensures that a fully populated 200-zone system can maintain operation for extended periods during power outages, meeting the standby time requirements for Grade 2 and Grade 3 certifications. This is particularly important for critical infrastructure, commercial properties, and facilities that require continuous security protection regardless of power availability.

How does the 3,000-event log benefit large installations?

The 3,000-event log capacity is triple that of smaller control panels and provides comprehensive system history tracking essential for large installations with 200 users and 200 zones. This extensive logging enables detailed forensic investigation after incidents, compliance reporting for insurance or regulatory requirements, and analysis of user behavior and system performance over extended periods. For commercial and industrial applications, the large log capacity means less frequent data downloads and more comprehensive historical records for security audits. Events include alarm activations, user access, system arm/disarm actions, faults, and maintenance activities, providing complete accountability and traceability for all system activities.
