    RAN START RELAY: When a CO line port 
    is 
    used for a ground stark application. a 24V dc 
    power source must be connected to the CO line 
    port for talk battery. A Loud Bell Control con- 
    tact assigned to that CO line port in program- 
    ming would provide contact closure to start the 
    Recorded Announcanent device. 
    When an SLT port is used, the RAN device must 
    be configured for xing trip operation {loop star& 
    The 9OV ac voltage sent to the SLT port will be 
    recognized by the RAN device which will then 
    answer the call.

    c- LY relay for Power Failure 
    : 
    Description 
    POWER FAILURE TRANSFER: When the in@ 
    nite Power Failure Transfer Unit is used for 
    Power Failure, It provides the relay transfer 
    circrrits for up to 12 CO Iines in the event of a 
    power or processo r faGure. Activation of the PFT 
    relays is controkd by a multi-use relay on any 
    4x8 Key In&face Board @3SF%] or Relay/Sensor 
    Module. A customer provided 12 volt DC power 
    supply is required to operate the unit. 
    With loss of power to the system or a failure of 
    system processing, the PFRJ will automaticaJly 
    connect up to twelve (12) ?33 lines to pre-wired 
    500/2500 type telephones. When power is re- 
    stored, the PFFU will automaticayl restore the 
    CO trunks and stations to normal operation. 
    These SLT stations do not have to be used for 
    intercom. but can be if so desired. 
    To disable a relay or sensor circuit: 
    a. Press the desired fkx button that corre- 
    spends to the relay or sensor circuit to be 
    disabled. 
    b. Dial 101 on the dial pad. 
    c. Press the HOLD button to save the entq.
