10. Relay Circuit Wiring:
Four Form-C contact relays are provided for controlling door lock mechanisms or alarm signaling. The
relay contacts are rated at 2 A @ 30 Vdc, resistive and are in a dry contact configuration. When you are
controlling the delivery of power to the door strike, the Normally Open and Common poles are used. When
momentarily removing power to unlock the door, as with a mag lock, the Normally Closed and Common
poles are used. Check with local building codes for proper egress door installation.
Door lock mechanisms can generate feedback to the relay circuit that can cause damage and premature
failure of the relay. For this reason, a diode must be used to protect the relay. Wire should be of sufficient
gauge to avoid voltage loss.
It is possible for the MR62e to provide power for a 12 Vdc door strike providing the maximum current is
not exceeded, see specification section.
11. Status LEDs:
At power up, LED 1 turns ON then LEDs 2 through 7 are turned ON then OFF in sequence.
The following table describes the LED
’s in the Normal Running mode:

Input IN6 Status: OFF = Inactive, ON = Active, Flashing = Fault. See note 2
J1-YELLOW Ethernet speed: OFF = 10 Mb/S, ON = 100 Mb/S
J1-GREEN
OFF = No Link, ON = Good Link, Flashing = Ethernet Activity
Note 2:
If this input is defined, every three seconds the LED is pulsed to its opposite state for 0.1
second, otherwise, the LED is off.
12. IT Security:
When installing the MR62e, it is important to ensure that it is done in a secure manner.
Upon installation, the user accounts to the web configuration page should be created with secure
passwords, and that all DIP switches are in the off position for the normal operating mode. The MR62e
is shipped from the factory with a default login account, which is enabled when DIP 1 is moved from OFF
to ON. The default login user name and password will be available for five minutes once enabled.
Therefore, it is important that at least one user account is defined, and the DIP switches are set to OFF
before the MR62e is commissioned. It is also highly recommended not to configure the MR62e with an
IP address that is accessible from the public Internet.
Diode Selection:
Diode current rating: 1x strike count
Diode breakdown voltage: 4x strike voltage
For 12 Vdc or 24 Vdc strike, diode 1N4002
(100V/1A) typical.
