It supports six inputs, including one Class A and five Class B circuits, and can monitor sprinkler systems, valve tampers, or contact-type alarm devices. The communicator automatically tests its phone line interface every 24 hours and switches to a backup line if the primary fails for more than 60 seconds, ensuring reliable transmission. With fuseless overload protection, automatic reset circuitry, and remote programmability, the 5104B is designed to reduce service calls and streamline fire protection monitoring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSix Supervised Inputs: Includes one Class A input and five Class B inputs for versatile system monitoring.\u003c\/li\u003e\n\u003cli\u003eReliable Digital Communication: Transmits alarm, trouble, and supervisory conditions via standard telephone lines.\u003c\/li\u003e\n\u003cli\u003eStand-Alone or Add-On Use: Functions as a dedicated communicator or as a DACT for an existing fire alarm system.\u003c\/li\u003e\n\u003cli\u003eAutomatic Supervision: Continuously monitors AC, batteries, zone inputs, and phone lines, with local trouble alerts.\u003c\/li\u003e\n\u003cli\u003ePhone Line Redundancy: Dual-line interface with automatic switchover if the primary line fails.\u003c\/li\u003e\n\u003cli\u003eRemote Programming: Supports downloadable programming for efficient configuration and updates.\u003c\/li\u003e\n\u003cli\u003eOverload Protection: Features fuseless automatic reset circuitry and fault indicators to reduce field maintenance.\u003c\/li\u003e\n\u003cli\u003eLong Standby Power: Provides up to 60 hours of standby operation with approved rechargeable batteries.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 5104B delivers the reliability and precision required for digital fire reporting, remote supervision, and NFPA-compliant fire monitoring applications.\u003c\/p\u003e","brand":"Silent Knight","offers":[{"title":"Default Title","offer_id":49105210540288,"sku":"5104B","price":2130.03,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/5104B.jpg?v=1785542594","url":"https:\/\/alotechparts.com\/products\/5104b-silent-knight-six-zone-addressable-fire-alarm-control-system","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
