EP104 – Outputs and Connecting a Lock
Outputs
The EP104 does not have any outputs natively. If an output is required to control traffic lights, control locks or
provide position indicators to a BMS on site, then the use of a DB407 Output Card is required. Please note that if you
are replacing a version 4.06 or below EP104, you will also require a new DB407 as the current control boards are not
compatible with the older versions of the DB401 (the original version of the output card). The DB407 is connected to
the EP104 and wired as shown below.
Please ensure that the EP104 is completely powered down before installation of the output card and that the
desired outputs are wired in as per the below, and then power the EP104 back on.
In general terms the DB407 is used to both connect a Magnetic Lock to the gate and/or connect a traffic light system.
Wiring a Magnetic Lock to a EP104
When it is being used to connect a Magnetic lock, we would recommend the use of o2 and i1 and run a separate
power supply positive to the Magnetic Lock through Output 2 relay (shown in the next page). This Output is already
pre-configured to be enabled in the closed position and disabled as soon as the gate gets a command to open.
