By adding ten additional Class B input circuits per module, installers can expand a system to accommodate more initiating devices such as pull stations, smoke detectors, and heat sensors. Up to two SK-5217 modules can be used per control panel, providing a total of thirty zones for larger installations. The module connects easily via the SBUS communication loop using a simple 4-wire connection, ensuring fast setup and reliable operation. It can be mounted either within the main control cabinet or remotely in the SK-2190 accessory cabinet up to 1,500 feet away, offering flexibility for various building layouts. Key Features 10 Additional Zone Inputs: Expands the SK-5208 system to support more detection and alarm devices. Flexible Installation: Mounts inside the main SK-5208 cabinet or remotely in an SK-2190 accessory cabinet. SBUS Communication: Utilizes a 4-wire connection for data and power transfer with reliable supervision. Long-Distance Mounting: Can be located up to 1,500 feet from the control panel for distributed installations. Scalable Expansion: Supports up to two modules per panel, increasing system capacity to 30 total zones. Easy Integration: Plug-and-play connection reduces setup time and wiring complexity. Supervised Inputs: Ensures all circuits are monitored for open, short, and alarm conditions. UL and NFPA Certified: Meets all industry standards for fire alarm system reliability and performance. The SK-5217 delivers the reliability and precision required for scalable fire alarm systems, providing flexible zone expansion and secure SBUS communication for extended installations.
