CONNECTING POWER TO ALPHA-PAGE
Alpha-Page receives primary power from a 12VAC, 20VA power transformer. DO NOT
use any power transformer with a secondary voltage
rating of anything other than 12VAC.
Connect the transformer secondary terminals to the two "AC" terminals on the MLS-SPU1
board, polarity does not matter. Use 18 AWG wire. Refer to drawing C022397-5. If the 12V, 7
amp-hour battery is to be used (for power back-up) it should be connected according to drawing
C022397-5. Make sure the red wire of the MLS-H1 battery cord (included with battery) is
connected to the positive (+) terminal of the battery via the quick-disconnect connector. The
black wire of the MLS-H1 battery cord must be connected to the negative (-) terminal of the
battery. The other end of the MLS-H1 cord is connected to the MLS-SPU1 board. Connect the
red wire to the "B+" terminal
. Connect the black wire to the "B-" terminal.
MLS-H1 may be
factory connected. Place the battery in the battery tray located in the bottom, center of the MLS-
EC1 enclosure.
MESSAGE PROGRAMMING
A nurse call paging system would be of little use if the messages being sent to pagers
could not be user programmed to include information such as a patients name and the exact
location (room number) the patient is calling from. Alpha-Page allows you to program a specific
message for each room
that will be sent to your pagers when a call is placed.
Before the user does any custom message programming, the system contains generic
programming which allows the system to function immediately without needing to be
programmed. Input 1 is programmed as "Input 001", input 2 as "Input 002", etc. The system will
be much more useful with your custom programming.
To enter the programming mode, simply plug a standard "PS/2" type computer keyboard
into the keyboard receptacle located on the MLS-SPU1 board (see drawing C022397-4). The
programming screen appears on the LCD display automatically. The top two rows comprise the
message field. This is where messages (up to 40 characters) will be entered. You may enter any
number, any letter (upper and lower case, use shift for upper case), and most punctuation
symbols. Some keys on the keyboard will not function. To update a message, simply type over
the old message. Use the <backspace> key to move the cursor back one position. Use the <space
bar> to erase the character located at the cursor position.
