XT AIM Description
The Medeco XT AIM (Access Interface Module) extends the capabilities of the Medeco XT System to interact with a
variety of access control devices often found around the periphery of a door opening such as electric strikes,magnetic
locks, alarms, cameras, lights, etc. As illustrated in Figure 1, the Medeco XT AIM consists of a Reader and an
Intelligent Controller assembly. The Reader is mounted in an accessible location while the Controller is located
in a secure location. The Reader and XT AIM Reader cable function as a communication bridge for the XT key and
the Intelligent Controller to exchange data. The Controller contains circuitry and output switches that when
authorized by an XT key can enable or disable connected devices.
More information on the XT key can be found on the Medeco website XT Key Tips page.
https://www.medeco.com/en/site/medeco/technology/ecylinder/medeco-xt1/medeco-xt/medeco-xtkeytips/
For an XT AIM Controller configured to any mode, the Control Key type provides a special and unique function.
The Control Key type in XT Web Manager is used to retrieve cylinder audits and as a tool to easily replace a
cylinder core. An XT key that is both authorized for an XT Lock and programmed as a Control Key type, will open
the XT Lock, but the relays will not be activated and the audit record event will be recorded as a Core Change
event. You should set your XT Key type to Operator or Operator+Audit for use with the XT AIM.
Information on using the Control Key Type
For a Medeco XT AIM Controller configured to any mode, using an authorized XT Key set to the
Control key type will not activate the relays and will record the audit event type as a Core
Change event. The Control Key type should not be used for XT keys assigned to key holders
who only use an XT Key for access. The Operator and Operator+Audit key type should be used
instead.

Using Your XT AIM
Relay and Power Terminals
On the side of the XT AIM Controller are the 9 Position Input/output (I/O) and 5 Position External Power
Terminals used to connect external devices and to provide auxiliary power.
The 9 Position I/O Terminal consists of the input and output terminals for the 4 relays. The 5 Position Power
Terminal provides the fused and non-fused external power source connection points. An AC or DC power supply
up to 24V can be connected to the Controller. The number of available I/O terminals allows for a wide range of
possible configurations for custom applications.
The XT AIM Controller contains a high power electro-mechanical relay and two low power digital relays that
provide safe and fully isolated control of external power sources. A control input is also provided for external
override of the relays. The following summarizes the type and function of the various XT AIM Controller relays.
Nine Position I/O Terminal
Electro-Mechanical Relay, Position (POS) 1/2/3
The electro-mechanical relay is single-pole-double-throw (SPDT) with both Normally Open (RLY NO) and
Normally Closed (RLY NC) contacts to a Common Contact (RLY COM). In the inactive state, the normally open
terminal (POS 1) is open and the common terminal (POS 2) is connected to the normally closed terminal (POS
3). When the relay is activated the common terminal (POS 2) is switched to the opposite state.
The electro-mechanical relay contacts are rated at 250V and up to 2 amps. The DC load breaking capacity of the
mechanical relay is 60 watts, i.e. 30 volts at 2amps. For inductive loads, an external appropriately sized snubber
diode must be installed across the load.
Digital Relays, POS 4/5 and POS 6/7

8
The two digital solid-state relays are single-pole-single-throw (SPST) normally open contacts. One solid-state
relay DIGITAL SW/DIGITAL COM, (POS 4/5) is activated during authorized key access events and the other relay
UNAUTH SW/UNAUTH COM, (POS 6/7) is activated during unauthorized events. The digital relays can switch up
to 24V AC or DC at 100 mA.
AUX Relays, POS 8/9
The AUX+ and AUX- inputs for the AUX function provide an external override for deactivating the relays. When
3V or greater is applied across AUX+ and AUX-, the mechanical and digital relays de-energize immediately. If
the AUX function is not used, POS 8/9 should be shorted together.
Five Position External Power Terminal
The XT AIM can be powered via an external AC or DC power sources. The DC input voltage range is between 7V
and 24V. The AC input voltage range is between 18 and 24Vrms. The XT AIM input current requirement is 30mA
maximum.
AC/DC24V/IN POS 1/RTN
The 5 position external power terminal is used for connecting an external power supply to the XT AIM
Controller. If used, external power is connected between the AC/DC 24V IN terminal and any of the RTN
terminals. The XT AIM is protected by an overvoltage protection circuit which is triggered when current greater
than 2 amps is drawn. If the overvoltage protection circuit is triggered, the circuit remains open until the current
drops to 2 amps or below, at which time the circuit closes and the XT AIM resumes normal operation.
Information on the AUX Terminals
If the AUX function is not used, POS 8 & 9 terminals should be shorted together.

9
AC/DC FUSED POS 2/RTN
Power to control external devices must be provided. The AC/DC FUSED terminal may be used for this purpose.
The voltage applied to AC/DC 24V IN is made available at the AC/DC FUSED terminal through a resettable fuse
(PTC). The PTC fuse trip rating is 2 amps.
Information on the Overvoltage Protection Circuit
Connecting a voltage greater than 24V to the AC/DC 24VIN terminal will trigger the overvoltage
protection circuit. When the XT AIM detects current greater than 2 amps, the circuit is
triggered. When current drops to 2 amps or less, the circuit is closed.
Warning –Connecting External Power to XT AIM Reader
DO NOT Apply voltages above 60V as this may damage the Controller and may render the XT
AIM inoperable.
