Partition Monitor Board

Partition Monitor for FBI XL4 & XL5 panels and Bridging together additional FBI XL4 & XL5 panels

·         This is the user guide for the Partition Monitor Board. It describes the operation and electrical connections for the monitor.

Overview

·         This device monitors and indicates the Arm/Disarm (or Day/Night) state of all active partitions in a system that uses the FBI XL4 and XL5 related panels. The monitor can also arm and disarm partition(s) when a user defined set of conditions are met (master/slave arming). Monitors can be cascaded to share information across multiple panels or to control additional partitions.

·         The monitor extracts information from the data sent from the alarm panel to the keypads. Each partition has at least one keypad and the monitor looks at the data sent to each one. The monitor can tell when a certain keypad's partition is armed or disarmed by monitoring the state of the arm LED on that keypad. The monitor only looks at data sent to LCD keypads and ignores data sent to LED keypads. It is likely that if a system uses a partition monitor it is complex enough to make using LED keypads impractical.

·         The board does NOT know the actual partition numbers. It only knows the state of the arm LED at each keypad address. The state of the lowest address LCD keypad (address 9) is displayed on the lowest number output (output 1), 10 on 2 and so on. So if partition number 6, for example, uses keypad address 9, the state of partition 6 comes out on output 1. If more than one LCD keypad is used for a given partition, the monitor does not know that and will display the state of that partition on more than one output.

Partition Monitor  Instructions

·         The board has two sets of outputs to indicate the state of the 8 keypad arming LEDs. One set follows the changes immediately and the other set can be delayed. If delay is NOT enabled, the outputs are exactly the same as the non-delayed outputs. If delay is enabled the outputs works as follows: When an LED on a keypad goes out (partition disarmed) the output follows immediately; when the partition is armed the delayed output waits 30 or 60 seconds (depending on whether the option jumper is cut) before turning on the corresponding output and LED. This allows an exit delay if using these outputs as a graphics driver or with the model 264 zone monitor.

Master/Slave Arming for Bridging together additional XL4 & Xl5 panels

·         The second job this board does is arm and disarm a slave partition depending on the state of master partition(s). This enables the monitoring of a common area shared by two or more other partitions. The master partitions are selected with the Master DIP switch. Turning switch #1 ON selects the partition of keypad #9 and so forth. The slave partition is selected by the Slave DIP switch in the same manner. Note: more than one partition can be selected as the slave partition and the board will still operate, but you may not get what you expect. Select at most one slave partition.

·         The system is completed by programming the control panel to make one point a keyswitch arm/disarm for the slave partition. The board then makes the slave partition follow the state of the master partition in the following manner: If ALL the master partitions are armed, the board will operate the ARM/DISARM relay to arm the slave partition. If ANY of the master partitions are NOT armed, the slave partition is disarmed. If the arming and disarming does not occur after 4 tries, the ARM FAIL or DISARM FAIL relay is activated until the conflict is resolved(the slave partition goes to the desired state, or the master partition(s) change state).

·         The slave partition is monitored continuously. If its state changes (say by arming/disarming on its own keypad) so it no longer agrees with the master partitions, the board will change the slave state back so that it agrees again. It is very stubborn in this way.

·         The board also has cascade inputs and outputs to allow several boards to work together. For example, if you have a system with more than 8 partitions, you would need more than one control panel. In that case there could be one partition monitor on each panel. The master partitions could be spread over more than one panel or the slave partition could be on a different panel from the master partitions. The cascade I/O is set up so there is no limit to the number of boards that can be "dasiy chained". There are two cascade connectors on each board with an input and output on each connector. When connected together, all the boards know if the master partitions are armed on all the boards. The slave partition will only arm if all master partitions on all the boards are armed. If any of them is not armed, the slave partition will be disarmed.

·         You can have the master partitions on one panel and the slave partition on another. To do this, put one board on each panel, and connect the cascade I/O between the two boards. On the board with the master partitions, select the desired master partitions, select NO slave partition. The master board will then send the arm signal to the slave board. On the slave board, select NO master partitions and select one slave partition. Now, the slave board will arm/disarm depending on the master partitions on the other board.

·         Of course the master partitions can be spread over two or more boards and there can be one slave partition per board. Another option is to have two boards on the same panel, each with its own set of master and slave partitions.

·         If you don't want to use the arm/disarm feature but only the partition indicators, select NO master and NO slave partitions.

DIP Switches

·         On any board select a partition to be part of the master set by moving the corresponding master switch to the ON position. Remember that you are actually selecting a keypad (#1=LCD keypad address 9, etc.) and not a partition as such. Select the slave partitions for this board (if any) in the same way on the slave Dip switch. Do not select more than one slave. You may be surprised.

Electrical connections

·         Refer to the pictorial for the location of these connections. Starting at the top left of the picture and going counter clockwise the connections are as follows.

·         DC Power: This three position terminal strip is for connecting power to the board. The top two connections are +12VDC and are connected together on the board. The bottom one is 12V ground or negative. This is also connected to the ground of the bus connections and the ground of the cascade I/O.

·         Keyboard Bus: Connections for the keyboard bus. The top one is for the Green wire from the control panel to the keyboard. This is the data line that the board monitors. The next one is not used and is reserved for future enhancements. The bottom one is ground. It is connected to the power ground.

·         Cascade I/O: The connector at the bottom of the board is one of the cascade I/O connectors and is identical to the one at the top. If several boards are to share Master partition information, they can be connected via these connectors. Simply place the boards so the connectors face each other and connect the pins directly across. Because the connectors are symmetrical, either one can be used. DO NOT make a ring of the boards. The last board on each end MUST have one connector unused. If the cascade I/O is not needed, make no connections.

·         Direct and Delay Outputs: The two sets of 8 outputs are electrically the same. Each output is designed to drive a 12VDC relay coil at a maximum of 50mA per output. The outputs are open collector transistors that pull low when the corresponding LED is lit (partition is armed). The other end of the relay coil or load would be connected to +12V. The outputs are compatible with the 8 channel relay expander. These outputs are not current limited so if the outputs are shorted to +12V they could be damaged.

·         Relay Outputs: The next three strips are the dry, isolated form C contacts to do the arm/disarm functions and the supervisory alarms. The contacts are labelled on the drawing and on the printed circuit board itself. The contact rating is 1 Amp at 30VDC.

·         LED Indicators: The board has 23 LED indicators to show the operations of the various features. The LEDs by the 8 way partition outputs show the state of those outputs. The LEDs are lit when the open collector driver is on which corresponds to the LED on the corresponding keypad being lit. The LEDs by the relays indicate the state of the relay. When the LED is lit, the relay coil is energized. The top LED by the relays is labelled GO and it lights when all the master partitions are armed and both cascade inputs are hi (indicating that the cascaded boards are satisfied too). When the GO LED is lit the board will arm the slave partition (if any) and when it is not lit it will disarm the slave partition. The two LEDs by the cascade connectors indicate the state of the outputs at those points. When the LED is lit, the output is high indicating that the master partitions are all armed AND cascade input on the other end of the board is high. The last LED is by the keyboard bus connections and is an indicator of processor and control panel activity. If the processor is running normally the LED reflects the state of the serial bus. This causes the LED to get brighter and dimmer as the data stream changes. If the LED has steady brightness for a long period the board may not be operating properly or the bus is inactive or not connected. Note that the keyboard bus may periodically stop working during the time the panel is booting up and while the panel is resetting the keyboards.

·         Interesting points: The panel expects to see certain keypads. It knows this because of the way the panel was programmed for the various partitions. If it does not get a response from one or more of the keypads (due to a bad connection, a failed or hung up keypad, a soft power supply or a programmed keypad not being present) the control panel tries to wake up the dead keypad. It does this by taking the data line low for a second or so and then resuming normal operation. This will "wake up" keypads that have gone off into the weeds and hopefully cause them to respond. You will know this is happening if the lights on all the keypads periodically go out then return to normal operation. The operation of the partition monitor is not affected by this action. The arm/disarm process works as follows. If the state of the slave partition is not what it should be, the board waits for 7 seconds to see if it changes. If not, the arm relay is closed for 1 second and released followed by another 7 second wait. The relay is operated 4 times and if the slave has not responded at the end of the last waiting period, the fail relay for the desired operation (arm/disarm) is closed and no more attempts are made. The fail relay holds until the slave partition is in the correct state again. This could be either the slave partition changing state or the master condition changing. Note that the board treats the arm and disarm operations similarly. If the slave partition is changed to the "wrong" state at any time (possibly by its own keypad or a fault) the board will spot that and initiate another arm/disarm cycle to force the slave to the correct state. However, there is the 7 second delay before anything is done, so if the slave is armed by an ARM ALL command, the board will go along as long as the master partitions arm within the delay time. The same goes for a DISARM ALL.
