Lathem LTR-RBR Telephone Accessories User Manual


 
Welcome to the LTR-RBR (Remote Bell Ringer)
Lathem’s LTR8-512 Master Controller for Clocks and Bells is capable
of storing up to eight (8) Schedules for Bells and Control Zones, each
of which may contain up to sixty-four (64) multi-function ‘Events’. An
‘Event’ may be defined by a very simple instruction, such as “Ring the
Bell on Circuit #4 for 3-seconds every day at 3:00PM”, or it may
contain a more complicated definition, as, “On Mondays, Wednesdays,
Fridays and Holidays, Activate Circuits #2, #3 and #4 at 2:45PM for a
duration of 7-seconds.” While eight Schedules may be stored in the
Master, the User may select which of the eight may be ‘Active’. As
time advances each minute, the day and time are automatically
compared against the Events stored in the Schedules which have been
selected as ‘Active’. If a match is found, the programmed Event is
executed. The Master Controller also provides the capability for
Manually Activated Bells, through the use of KeyPad Function
[#][3}[#], which allows the user to select one or more of the Bell
Circuits to be activated by subsequent press of the [#] key.
