ELK-MM220 HOOK-UP DIRECTIONS
The ELK-MM220 has been factory programmed with a sample application as labeled on
the unit, for other applications it must be reprogrammed before installation. The Program
Development Kit (ELK-MK400S) is required to re-program the ELK-MM220 if desired. The Develop-
ment Kit contains software and programming instructions needed to program the ELK-MM220. The
program is written using the Elk Magic Module Software and debugged by using the ELK-MM443
Magic Module that is included in the development kit. The program is then download into the ELK-
MM220 through a 5 conductor ribbon cable connected between the ELK-MM443 J1 connector and
the ELK-MM220 J5 connector. Note: If using the Clock/Calendar Module(ELK-MC100), temporarily
remove it to gain access to the ELK-MM443 J1 connector.
The ELK-MM220 has two digital inputs that switch from Low to High at approximately 2 Volts. Each
input is jumper selectable at J1 & J2 for an onboard 2K input resistor either pulled up to +12 Volts,
or pulled down to Ground. The ELK-MM220 has two form C relay outputs. Relay 2 is jumper
selectable using J3 to switch the output through a transistor (100mA max). Placing J3 to the OUT
position will disable Relay 2 and allow the Relay 2 COM terminal to be pulled to ground through a
transistor when activated. This setting handles up to 100mA of current and is intended for applica-
tions like flashing an LED. If more current or dry contacts are required then set J3 to IN and use the
Relay 2 contacts, the transistor will be disabled.
Test the ELK-MM220 after downloading the program to ensure that it functions as desired. The
ELK-MM220 can be reprogrammed multiple times.
*The ELK-MM220S version is required if using Savoy Automation Software.
