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.
The “Remote Bell Ringer”, an accessory for the LTR8-512 Master
Controller (Firmware v4.08 and above, only), allows an Operator to
select and activate one (1) of the eight (8) possible Bell Circuits or all
Bell Circuits (those circuits not defined as Clock Control Circuits) in
the Master Controller. The selection made will execute when the push
button on the Remote Bell Ringer’s Panel is pressed, and those circuits
will remain activated until the button is released.
The Assembly of the Remote Bell Ringer consists of an Electronic
Circuit suspended beneath a cover plate for a double-gang switch-type
electrical box (not supplied with the product). The Circuit includes a
low-power MicroProcessor, a method of selecting the ‘Address’ of the
Master to be remotely controlled, and a 4-screw Terminal Block for
Installer Interconnect. Two screws of the Terminal Block are for
attachment of the Twisted-Pair (Cat-3 typical) low-voltage Network
Communications Cable to the Master’s RS-485 Port. The other two
screws are to be used for supplying 9-24V AC/DC as continuous power
source to the unit.
On the face of the cover plate are a 9-position Rotary Switch (to select
the Circuits to be made ‘Active’), a Push Button to send the Command
to the Master, and an array of lighting Status Indicators by which the
Operator can receive confirmation from the Master that the Manual
Bells Command has been accepted and acted upon.
Installing the LTR-RBR
To install the Remote Bell Ringer, simply set the hidden Address
Selector switch / jumpers to match the Master’s Programmed Address
(default = Code 65) and attach the Communication Cable wire-pair
(with proper polarity) and the low-voltage Power Pair to the Terminal
Block, then secure the cover-plate to the electrical box with four 6-32
FH screws.
Operational Description
To use the Remote Bell Ringer, the Operator will first select, via the
Rotary Switch, which of the Bell Circuits are to be made active.
Selected Circuits that are not configured as Bell Circuits in the Master
Controller will be ignored
yThe ‘OFF’ position may be used to de-activate all Bell Circuits
yPositions ‘1’ to ‘8’ may be used to select a single Bell Circuit to be
made ‘Active’
yThe ‘ALL’ position may be used to activate all circuits configured
as Bell Circuits.
After setting the selected position of the Rotary Switch, the Operator
should press the ‘ENTER SELECTION’ Push-Button. This will ‘wake-
up’ the Microprocessor (indicated by a brief ‘flash’ of the indicators)
which will, in turn, read the Switches and transmit the appropriate
Command to the Master. It will wait for a reply from the Master, which
will indicate the Bell Circuits which are now Active, and display that
information on Lighting Indicators as confirmation to the Operator that
the Command has been accepted and executed by the Master. The lit
Indicators will remain active for 2 seconds after the button is released,
after which the unit will go back to ‘sleep mode’, to conserve power.
