It includes a keypad interface for direct annunciation and monitoring of active telephones and trouble signals. The unit supports expansion through the FFT-24 board, allowing up to 48 zones per system. Each zone uses addressable monitor modules (SK-Minimon) and Fire Fighter Telephone Jacks (FFT-FPJ) to ensure scalable and code-compliant emergency communication coverage. Key Features: Scalable Design: Supports up to 48 addressable zones when paired with one FFT-24 expander board. Multi-Handset Operation: Allows up to 10 firefighter handsets to communicate simultaneously. Comprehensive Supervision: Monitors phone activation and system trouble conditions in real time. Auto Programming: Includes JumpStart™ auto-configuration for rapid setup and deployment. Trouble Relay Output: Equipped with a Form C trouble relay for external signaling and monitoring. UL and FM Certified: Fully listed and approved by UL, FM, CSFM, and NYFD (MEA). Rugged Construction: Housed in a durable, red steel cabinet suitable for surface or flush mounting. Flexible Integration: Compatible with Silent Knight fire alarm control systems and 24 VDC notification circuits. The SK-FFT delivers the reliability and precision required for critical firefighter communication and emergency coordination.
