BT-XF Fire Communicator and Controller Features Narrowband radio communication with optional fallback to Hardwire lines with any of the D-21 Fire Management Systems Narrowband radio is FCC certified for narrowband operation and meets the requirements of the NTIA (National Telecommunications and Information Administration) Manual of Regulations and Procedures for Federal Frequency Management Provides automatic and manual control of local or remote devices such as turning on pumps based on timed events, input from a fire alarm control panel, or manually activated from the D-21 (Additional components/etc. may be required) Provides eight relay driver outputs and four supervised zone inputs: Eight onboard open-collector relay driver outputs can connect to the BT-X relay board or to relay coils that remotely control equipment such as pump activation inputs, HVAC dampers, lighting, door openers, runway barriers, and gates. Four supervised fire zone inputs for connection to fire detection and monitoring devices located within 15 feet of the BT-XF; these are supervised for open (trouble), short (alarm), single-ground fault, and double-ground fault conditions Four zone LEDs (one for each zone) reflect the condition of the zones: trouble, alarm, or normal on BT-X main board Status LEDs reflect the status of the BT-XF: general alarm, general trouble, system fault, in-communication, carrier detect, transmit, primary power, battery boost charge, and battery float charge on BT-X main board Supports up to 7 zone expansion backplanes into which fire expansion cards can be plugged (3 in single enclosure; 7 in double enclosure) Each zone expansion card provides four zone inputs and eight relay outputs for connection to local or remotely located devices Each expansion card has five LEDs: the PWR LED indicates power is being supplied to the card; the remaining four LEDs indicate the status of the four zone inputs Each BT-XF can support up to 60 zones and up to 40 relay outputs that may be controlled from the D-21 Management System One selectable RS-422/RS-485 port for communication with peripheral equipment or connection to a local access controller. One RS-232 port used to program the BT-XF via connection to a laptop computer 115 or 230 Vac power (50/60 Hz) monitored with automatic switchover to backup battery power that provides standby power; the number of hours depends on the battery Self test, stuck transmitter disconnect, reset, acknowledge, and battery reconnect switches Local audible alert Real-time clock and calendar 1/2 Mb of program memory 1/2 Mb of non-volatile data storage Fits in a variety of enclosures; the enclosure size depends upon how many expansion cards are needed Factory Mutual approved Ordering Information Part Number Description 227-600-xx BT-XF in a 20 inches high x 12 inches wide x 4 inches deep single-wide enclosure; specify frequency  (Up to 3 Backplanes) 227-603-xx BT-XF in a 20 inches high x 25 inches wide x 4 inches deep double-wide enclosure; specify frequency  (Up to 7 Backplanes) 176-212-00 BT-X zone expansion backplane 176-206-00 BT-XF expansion card (two per zone expansion backplane) 176-214-00 BT-X relay board with 8 onboard Form C relays (with Cable) 513-412-00 BT-X enclosure tamper switch kit
