    How to prevent relays 9-16 or 73-80 from latching unexpectedly.

    The default settings for the BFSK/Relay Point Assignments on a 7000/9000 or 'B' Series control panel are non-zero values between 1 and 8. These default settings were intended for the purpose of sending signals in BFSK format, which do not apply when signals are sent in Modem format.

    When using BFSK/Relay programming, the actual relay (see chart below) corresponding to the entry in the BFSK/Relay column in Point Assignments latches when the selected point goes into alarm. The number entered, always 1-8 for the 8 available BFSK/Relays, can be used any number of times through programming. This is particularly useful when any or all points in a point range go into alarm and cause a single event to occur, such as activating cameras or opening fire doors. 7000 series control panels latch selected octorelays between 9-16 and 9000 series control panels latch selected octorelays between 73-80 when corresponding points in point assignments go into alarm.

     

    • BFSK/Relay                 Actual relay#
    • Entry                7000 (zonex 1)  9000 (zonex 2)  
    •      1                      9                      73
    •      2                      10                     74
    •      3                      11                     75
    •      4                      12                     76        
    •      5                      13                     77
    •      6                      14                     78
    •      7                      15                     79
    •      8                      16                     80

     

    When points programmed to use BFSK relays go into alarm, the corresponding relay remains latched until the alarm is acknowledged and cleared from memory.
