Issue Will an Answering Machine cause the D168A not to answer when accessed locally? Solution Some answering machines load down the phone line and cause it to go below 7 VDC. The D168A needs at least 7 VDC to properly process the DTMF tones.

How to determine why Central Station doesn't receive supervisory events sent with BFSK format. When sending signals using BFSK format, the central station does not receive Supervisory events.

Issue How can I tell a B series panel from a non B seies panel?   Solution   There are few ways. Look at the main eprom chip on the board, version 3.17 and under are a B series panel. It will also be labeled D9112B or D9112B1. Press CMD59 at a keypad, versions 3.17 and under are B or B1 series panels. Latch and unlatch the reset pin on the cpu. If it beeps for 8-10 seconds it is a B or B1 series panel.

FA210 REDUCED-SIZE UNIVERSAL TRANSMITTER Available in off-white (FA210). For use with any standard contact or sensor, this reduced-size universal transmitter comes with case tamper and supports an end-of-line resistor. Mounting bracket included for quick and easy installation. FA210W REDUCED-SIZE “WIDE GAP” DOOR/WINDOW TRANSMITTER Available in off-white (FA210W). Same as the FA210 but includes two built-in magnetic reed switches, one on top, and one on the side for maximum flexibility. Includes magnet that supports a 5/8” gap. Can support a N/O or N/C external contact when using the reed switch. USed with the FA400 Receiver

Issue What is the force arm or bypass max on the DS7100?   Solution   The bypass max is only limited by point programming, if the point is programmed in data digit 3 as bypassable then it may be bypassed no matter how many other zones may also be bypassed while arming.

How to interpret Zone 15 displaying on the DS7100 keypad when only 14 zones are available on the panel.

Issue Can zones 7 and 8 be used as normally open zones, and do they require any supervision?   Solution   Zones 7and 8 are not supervised on the D2112 and D2212 panels and therefore can only be used as normally closed zones, they will not work as normally open zones because no EOL is used. Voltages of 2.4 to 13.9VDC would be an open condition while voltages 0.0 to 1.4VDC would indicate a closed circuit on these points.

Issue How do I tell if my wiring is good and all the devices are connected on the D6112 keypad bus? Solution Remove the data wires from terminals 11 and 13 on the control panel. Also remove the power going to those devices. Using a multimeter set to read resistance, place one lead on a data wire and the other lead on the other data wire. The correct resistance reading should be 9K Ohms per device connected. Number of device    /   Device Resistance   /    Wire     /      Max resistance 1                                        9 k ohms           15 k ohms          23 k ohms 2                                      18 k ohms           15 k ohms          32 k ohms 3                                       27 k ohms          15 k ohms          41 k ohms 4                                       36 k ohms          15 k ohms          50 k ohms

Issue How is the phone line monitor turned on or off in programming?   Solution   DS7100 version 5.03 or higher. The phone line monitor feature has been enhanced to provide output to allow enabling or disabling of the featrure through programming and to automatically reset after the phone line is restrored. The feature is controlled in data digit 2 of program address 89. To enable the phone line fault monitor without an audible output, program line 89 as 0200. To enable the phone line fault monitor with a keypad warning beep when the system is disarmed and siren output when the system is armed, program line 89 as 0600. To disable phone line fault monitor program line 89 as 0000.

Issue How does the phone line monitor for the DS7100 operate?   Solution   If the monitor detects a phone line fault for more than 50 seconds, the power LED will begin to flash.  If the audible output has been enabled in line 89, the keypad sounder will pulse every ten seconds if the control is disarmed. If the panel is armed, the siren output will activate. To ascertain if the trouble condition is indeed a phone line failure, enter # 87 at the keypad. The display will indicate "Communication Failure". If the "System Trouble Report" (line 51) is programmed the system will try to send this report. A phone line failure may be caused by: A cut or missing phone line. A reversed connection (Tip, and Ring Reversed) A miswired jack To clear the error; Determine the cause of the failure and eliminate the cause. After eliminating the cause of the failure, wait at least ten seconds. The error will clear if the problem has been eliminated and the LED will stop flashing provided a failure has not occurred on the central station phone numbers. If a failure has occurred at the central station restore by entering # 87 * at the keypad.
