BT-XS Security Communicator and Controller

Features

• Hardwire or narrowband radio communication with the D-21 Force Protection System 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 Supports connection to door interface reader modules and access control devices such as keypads or card readers to control who enters a building and to identify personnel entering or leaving a building; the database is resident on the local access controller, updated by the D-21 as needed. Provides eight relay driver outputs and four supervised zone inputs:
• Eight onboard open-collector relay driver outputs can connect to relay coils to remotely control equipment such as pumps, barriers, and gates. These outputs can also drive remote annunciator LEDs. Four supervised security zone inputs for connection to security detection and monitoring devices located within 15 feet of the BT-XS; these are supervised for open, short, single ground fault, double ground fault, access resistance (10 K), and secure resistance (22 K). Zones can be programmed to operate as access/secure, central initiate, entry/exit delay,constant secure, automatic, and master control. Four zone LEDs (one for each zone) reflect the condition of the zones: alarm, access, or secure
• Status LEDs reflect the status of the BT-XS: general alarm, general trouble, system fault, in-communication, carrier detect, transmit, primary power, battery, battery boost charge, and battery float charge

Supports up to 31 zone expansion backplanes into which security expansion cards can be plugged

• 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-XS can support up to 252 zones and 504 relay outputs with 62 expansion cards installed

One selectable RS-422/RS-485 port for communication with peripheral equipment such as in-building or area-wide personnel alerting systems or connection to a local access controller. An alternative use of this port is hardwire connection to multiple BT-XSs connected together for communication to the D-21. Two full-duplex RS-232 ports used to program the BT-XS via connection to a laptop computer or for connection to peripheral equipment that does not have a RS-422 port/RS-485 port 115 or 230 Vac power monitored with automatic switchover to backup battery power that provides standby power; the number of hours depends on the battery and the number of zones 60 hours of ac fail runtime with a standard battery and four zones 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

• Communication and line security comply with DCID 1/21 Annex B (Class II) and UL 1076 Class AA

Description

The BT-XS Security Communicator is Monaco's newest data link communication product for the D-21 Force Protection System. Communications may be by hardwire or narrowband radio. A versatile product, the BT-XS can be used for Personnel Alerting, Remote Device Activation, and Access Control applications. The BT-XS provides personnel alerting by activating prerecorded messages, which can be selected from a message list and broadcast on a building voice evacuation system. The D-21 controls when and where the message is played.The BT-XS provides automatic and manual control of selected devices based on input from the D-21. For example, gates may be opened or closed, lights turned on or off, and motors and pumps started or stopped. This remote device control can be automatically prompted by the D-21 from timed events, from alarm signals received from a fire alarm control panel, or from manual initiation by the D-21 operator.The BT-XS builds on the D-21 site, facility, and people database to provide a fully integrated access/control system. The D-21 centralized database maintains all user information including photographs, biographical data, access levels, and facility rights. This information is transmitted to the access controller and updated as needed. Access control devices, such as keypads or card readers, can be connected to the BT-XS with optional access controllers to restrict who enters a building and to identify personnel entering or leaving a building.Communication between the BT-XS and the D-21 is supervised; the BT-XS reports status changes by automatic and manual poll/rely/acknowledge routines. It provides electrically supervised connections to access/secure key switches or keypads, security sensors or security control panels. Each BT-XS provides eight onboard relay driver outputs and four supervised zone inputs. The BT-XS onboard open-collector relay driver outputs can connect to relay coils to remotely control equipment such as water pumps; the D-21sends a command to the BT-XS to activate its relay outputs. These relay driver outputs can also drive remote annunciator LEDs. The zone inputs are supervised for open, short, single ground fault, double ground fault, access resistance (10 K), and secure resistance (22 K). The onboard zone inputs must be connected to devices within 15 feet of the BTX, installed with wiring in conduit. The BT-XS supports up to 31 zone expansion backplanes. Two security expansion cards can be plugged into each zone expansion backplane. Each expansion card provides an additional four zone inputs and eight relay outputs for connection to local or remotely located devices. At full capacity, the BT-XS offers 252 zones and 504 relay outputs. Each BT-XS provides status LEDs and zone LEDs. The status LEDs reflect the BT-XS status: general alarm, general trouble, system fault, in-communication, carrier detect, transmit, primary power, battery, battery float, and battery boost charge. The zone LEDs indicate the zone status: alarm, access or secure. Each expansion card LEDs indicate power is being supplied to the cards and the status of each zone input: alarm, access, or secure. Two RS-232 and one RS-422/RS-485 ports are included on each BT-XS. The full-duplex RS-232 ports can be used to program the BT-XS via connection to a laptop computer running the BT-XS configuration software; these ports can also be used to connect to equipment that does not have an RS-422/RS-485 port and to connect to input/output devices such as modems or a compatible fire alarm control panel. The RS-422 port is primarily used as a communication port for controlling equipment for personnel alerting such as in-building and area-wide voice evacuation systems. This port can also be used as a hardwire connection for multiple BT-XSs connected together, communicating with the D-21.The BT-XSs primary source is115 or 230 Vac power; its secondary power is sealed lead-calcium type batteries that require no maintenance or water addition. If loss of primary ac power occurs, the BT-XS automatically switches to battery operation. The switchover is accomplished with no interruption of protection service. Loss of ac power exceeding 60 seconds causes the transmission of a special ac fail message including theBT-XS identify code to the D-21. Transfer to normal ac power is automatic and activates the internal battery charger causing automatic battery recharging using a dual rate charge that provides automatic boost and float charging modes. The BT-XS power supply contains surge protection meeting the requirements of IEEE C62.41.

The BT-XS battery supply provides sufficient power to operate it in normal standby status for a minimum of 60 hours (depending on the battery used and the number of zones) and is capable of providing power for continuous polling and transmitting alarm and status changes throughout the standby period. Restoration of ac power initiates a battery recharge operation with no loss of status. Each BT-XS constantly monitors and supervises its own battery charger and battery. A battery fault message is transmitted by the BT-XS when the battery voltage falls below 85% of the rated capacity. Other battery fault messages are transmitted to the D-21 indicating the battery is disconnected or battery charger failure.
