3.7.4.2 Additional Output Relay Wiring
In Paired Reader Mode, the AIM-1/2SL has the capability of controlling 3 ADA output relays in addition to an
ADA for the strike relay (for a total of 4). In Unpaired Reader Mode (AIM-2SL only), each reader can control
3 ADA modules in addition to the ADA strike relay for each reader, thus a total of 8 ADA modules. Thus at
maximum, there are a total of five output relays available per reader when using Unpaired mode (internal
strike relay, an external strike relay, and the three extra output relays). The two strike relays (internal and
external) perform the exact same functions, releasing the door when required. The extra three relays
available are defined as Local Alarm, Aux Out 1, and Aux Out 2.
NOTE: In Paired Reader Mode (default mode), the second onboard relay functions as Local Alarm.
The function of the Local Alarm relay is pre-programmed in the firmware of the reader and cannot be
modified. The reader will activate this relay whenever any of the following conditions exist:
Door Forced Open (Reader Detects the Door Contact Input Open Illegally)
Door Held Open (Reader Detects the door has not closed after legal entry)
Auxiliary Alarm (Either of the Auxiliary Alarm inputs are opened)
Reader Tamper (AIM-1/2SL Tamper Input is opened)
Because control of the local alarm relay is completely self contained within the reader interface, this relay will
activate anytime the above conditions occur, regardless of proper functioning of the other components in the
system. This relay does not require communications to be working, the controller to be functioning, the PC to
be operating, or the software to be running. The only thing required for the local alarm relay to operate is
power (battery backed up UPS power supplies may be used). Because of this extremely reliable operation,
the Local Alarm relays are often used as a redundant backup to other system functions in highly critical
areas. Some typical uses for the Local Alarm relay are as a standalone siren above certain doors,
connection into other alarm systems, and small bell to signal Held Open to get the people holding the door
open to close it.
FOR PROPER OPERATION OF THE LOCAL ALARM RELAY, ALL UNUSED INPUTS MUST BE
TERMINATED. In the Unsupervised mode, jumpers should be connected to any unused Aux Alarm or Door
Contact Input. If the reader is being used in the supervised mode, 300 ohm resistors or ATM-30 terminators
with a jumper between inputs 1 and 2 should be connected to all unused inputs. For information, see the
section regarding input supervision.
The Aux Out 1 and 2 relays are programmable relays that require programming to configure their operation.
They may be linked to other system alarms or events to trigger a siren or bell. An example may be to
connect a siren to a Aux Out relay connected to a reader near the security Supervisor's office and configure
the software to activate this relay (siren) whenever any door in the entire system is Forced Open. The actual
capabilities of the Aux Out relays are dependant on the software system being used and the type of
controller.
The use of any of these relay capabilities requires addition of external ADA-10/11 relay modules. THESE
RELAYS ARE NOT PROVIDED WITH THE AIM-1/2SL AND MUST BE PURCHASED SEPARATELY. The
ADA-10 relay module is a potted module suitable for use in areas where extreme environmental conditions
may be present, the ADA-11 is a smaller, non-potted version that should not be used in areas of extreme
environmental conditions. See the above section for more information about the ADA-10 and ADA-11
external, high-security relay modules.
3.7.4.3 ADA DIP Switches/Jumpers
In order for ADA-10 and ADA-11 devices to operate properly, The the corresponding Jumpers or DIP
switches must be set in order to define the purpose the ADA will serve.
