    There are 100 system tracks available (7 of which are used as prompts for the voice mail) and these tracks reside in the system section of the DVR memory. The FF-8070 DVR is a random access system, which means that tracks can be recorded and rerecorded as often as desired without any special consideration for any previous record operations.

    P25 on the FF-800, while P5 on the DVR connects to P7 on the FF-800. The FF-8070 card should be placed in an RF tight enclosure and be placed as close as practical to the FF-800. It is recommended that the FF-8070 be installed in the same chassis as the FF-800 to allow the cable lengths to be kept to a minimum.

    • Enter 13001nn (nn = track# to record) and wait for the "DVR" response from the FF-8070(or "DVR B" if source = auxiliary) -- the DVR waits for a COS signal (or any DTMF digit if input=B) at which point the recording operation begins.

The number of installed DRAMS is preset at the factory for the amount of memory that the DVR shipped with -- however, if additional memory is later added, this value must be changed to reflect the number of DRAMs installed.

  • Page 16: Appendix A: Ff-8070 Wiring

    APPENDIX A: FF-8070 WIRING The connections to the FF-8070 are all accomplished via 10 conductor ribbon cable. There are two cables provided, one for the power/audio (connects P3 on the DVR to P25 on the FF-800) and one for SPI communications (connects P5 on the DVR to P7 on the FF-800). The only remaining connection is that of a back-up battery to P2 of the DVR.
