access control system and without any prior knowledge of the system operation. This normally means that
some form of emergency crash bar or manual door release be provided. IT IS THE RESPONSIBILITY OF
THE INSTALLER TO INSURE ALL LOCAL CODES ARE FOLLOWED DURING INSTALLATION.
3.6.4 Auxiliary Alarm Inputs
This is a normally closed input and should have a jumper installed if not used!
Terminal Connectors: AUX, AUXR (See Table 2.1 )
Each reader input on the AIM-4SL includes one Auxiliary Alarm circuit. These inputs may be used for many
purposes that can be configured in the host software. The capabilities will depend on the particular software
system in use. Normally these inputs will be used for monitoring external alarm points such as motion
detectors or glass break detectors. They may also be used as input triggers for Internal Variable and
Reaction linkage when used with the APACS software. A switch contact may be connected to an Aux Alarm
input on reader 4 and the software can be configured to close a relay on reader 23 for example. The full
capabilities of the Aux Alarm inputs are described in the software manuals. Specifically, reference the
Internal Variable and Reactions portions of the APACS software manuals.
In the default configuration of the AIM-4SL, this input will be linked to the corresponding Auxiliary Output i.e.
Reader 1 Auxiliary Input-Auxiliary Output 1. Thus, if the input is in alarm state (open) the output will be
energized. This feature is configurable through the host software so that the auxiliary output can respond to
other inputs within the system. For more information consult your software documentation.
3.7 Output Relay Wiring
The AIM-4SL has eight output relays onboard, with a dedicated strike relay and an additional Auxiliary Output
relay for each of the four readers. In addition to these onboard relays, external high security relay modules
can be substituted. The AIM-4SL can support a mixture of use of onboard and external relay modules.
3.7.1 Strike Wiring, General
Typically, doors are held closed and released by one of two methods. An electric door strike is installed in the
door frame, replacing the mechanical strike plate. This type of strike has a “gate” that is normally held closed
and is released by command from the reader. This allows the door to be opened. A second type of lock is a
electro-magnetic lock which is a two piece device mounted on the perimeter of the door. A solid plate is
mounted to the door and a electro-magnetic lock is mounted adjacent to the plate on the frame of the door.
The electro-magnetic lock firmly holds the plate mounted to the door, holding it closed until the power is
removed by the reader, allowing the door to be opened.
Most electric locks are available in two configurations, Fail-Safe and Fail-Secure. Fail-Safe locks require
power to hold the door closed and will release the door when power is removed. This type of lock will open
the door if a power outage occurs. This is desirable for doors used as emergency exits. Fail-Secure locks
hold the door closed automatically and require power to release the door. This type of lock is desirable for
securing doors in high security applications. Electro-Magnetic locks are typically only available in the
Fail-Safe configuration.
Electric locks are also available in a range of operating voltages. 12 volts DC or 24 volts DC are the most
common. AC power strikes are also available but are not widely used because of the difficulty in connecting
suppression circuitry (see Part 3.6.5.2) and the inability of providing battery backup power in the event of
power failure. If a 12 or 24 volt DC lock is selected, the same power supply used to power the lock may be
used to power the reader. UNDER NO CIRCUMSTANCES SHOULD AC POWER BE APPLIED TO THE
AIM-4SL READER INTERFACE!
A typical electric door lock (strike) will require approximately 250 mA. (.250 amps) to control. The relay
contacts on all Apollo relays are capable of switching up to 24 volts DC at up to 2 amps. If the particular
locking device requires more that 2 amps to control, a separate, external relay capable of switching the
required amount of current must be installed.
The AIM-4SL provide two methods of strike control for each reader. The first method is by use of the internal
strike relay. Four such relays are provided on the AIM-4SL—one for each reader input. Each is rated for
