8. Input Circuit Wiring:
The eMAX-MR62e provided Six (6) inputs that are typically used to monitor door position, request to
exit, or alarm contacts. Input circuits can be configured as unsupervised or supervised. When
unsupervised, reporting consists of only the open or closed states.
When configured as supervised, the input circuit will report not only open and closed, but also open
circuit, shorted, grounded*, and foreign voltage*. A supervised input circuit requires two resistors be
added to the circuit to facilitate proper reporting. The standard supervised circuit requires dual 1K
Ohm, 1% resistors and should be located as close to the sensor as possible. Custom end of line
(EOL) resistances may be configured via the host software.
NOTE: Grounded and foreign voltage states are not a requirement of UL 294 and therefore not
verified by UL.

9. Relay Circuit Wiring:
The eMAX-MR62e includes four (4) relays with Form-C contacts (dry) that provide for controlling door
lock mechanisms or alarm signaling. Each relay contact is rated at
2A @ 30Vdc resistive.
When
controlling the delivery of power to the door strike, the Normally Open and Common poles are
typically used. When momentarily removing power to unlock the door, as with a mag lock, the
Normally Closed and Common poles are typically 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, it is recommended that a diode be used to protect the
relay. Wire should be of sufficient gauge to avoid voltage loss.
It is possible for the eMAX-MR62e to provide power for a 12 Vdc door strike providing the maximum
current is not exceeded. See specification section.
