Alpha Communications AlphaTouch - DIP Switch Settings for Numbering Relay Boards

• If more than one (1) Relay Board is used, you must connect a model# CT032AEJ jumper cable from the
Serial Out connector from the 1st Relay Board to the Serial IN connector on the next Relay Board,
connuing to add jumpers as addional relay boards are required. Each CT032AEJ jumper cable
is only 12 inches long, so make sure the mulple relay boards are as close together as feasible for
proper wiring connecons, while sll allowing room for wiring the appropriate number of output
relay terminals.
• On the LAST Relay Board only, connect the model# KE-PWR5/2A 5VDC power supply, using the provided
Female plug connector to the Serial Out connector. This 5VDC regulated power supply should be
used only to power the relay board(s) and should not be used to power any other equipment. Make
sure to align the connector properly to the 5 pins, as you did for the CT032AE6 cable.
oIMPORTANT NOTE: DO NOT APPLY THIS 5VDC POWER UNTIL ALL WIRING HAS BEEN CHECKED
AND ALL OTHER CONNECTIONS HAVE BEEN MADE
• Connect one wire (COMMON WIRE) to either of the Common terminals marked COMM on the 1st relay
board and jump this wire to either of the Common terminals marked COMM on the next relay board,
and connue unl all of the COMM terminals on all of the relay boards are jumpered together. You
may use either of the screw terminals marked COMM on each relay board, as these are internally
connected together on the board circuitry. We provide two (2) COMM screw terminals to make it
easy for you to connect mulples COMMON wires on each board. Connect this ‘COMMON’ to the
wire that would normally connect to one side of all of the pushbuons on a typical intercom or
video-intercom entry door staon.
• Once all of the relay boards are connected together, please determine whether or not your relay
boards have been preprogrammed. If so, they will be clearly labeled with a relay board number. If
not, you need to set the ‘DIP’ switches on each board to the Board# you wish to use to idenfy each
board according to the chart below. CAREFULLY, slide the ‘DIP’ switches ON or OFF as indicated, using
a small rubber or plasc (non-conducve) tool. You can install a maximum of 16 of the relay boards
on each relay controller, for a total maximum capacity of 512 relays. In order for the relay controller
to properly signal an individual relay to acvate, you must individually number the relay boards (from
1 to 16). Since each relay is already numbered 1 to 8 (or 1 to 32) on each relay board, to trigger a
specic relay to acvate you need to know the Board# (1-16) and the Relay# and set that informaon
into the appropriate area of of your cloud sengs for the funcon you are performing.
oIMPORTANT NOTE: EACH RELAY BOARD MUST HAVE A UNIQUE BOARD#. FOR SIMPLICITY OF
INSTALLATION, WE RECOMMEND THAT YOU NUMBER THE RY032AE BOARDS SEQUENTIALLY
(1 TO 16), WITH THE ONE CONNECTED TO THE CT032AE6 CABLE BEING BOARD# 1, ETC., BUT
YOU DO NOT HAVE TO NUMBER THEM SEQUENTIALLY
