AIM-4SL - 4 Door Downloadable Reader Interface Module

Apollo’s AIM-4SL Downloadable Reader Interface provides mission-critical performance for the most sensitive Access Control Systems throughout the world.  With full hardware control for 4 doors, the AIM-4SL not only supports advanced features such as Precision Access and 38 Access Levels per card, but can maintain normal functions in off-line mode thanks to its up to 20,000 cardholder/7,000 event local database. That means you can be assured access to your site won’t be compromised even in the most extreme circumstances and your records will be safely stored in memory until communication is restored to the system controller.

The AIM-4SL links door hardware with one of Apollo’s AAN or AAM Series Controllers, providing inputs for a full range of reader types including proximity, smart card, and biometric.  Up to 8 card formats are supported simultaneously allowing you to mix and match different reader types or easily migrate old card populations.

Going beyond the standard, all door hardware inputs for door contact, exit push button and device tamper are supplemented with 4 Supervised auxiliary inputs for use with motion sensors, panic buttons, door bolt monitors or any other.

standard input device. A full array of output options are available for the AIM-4SL including 8 on-board SPDT outputs (4 door strike and 4 auxiliary).  Not stopping there, the AIM-4SL supports up to 16 Apollo ADA 10/11 Digital Relay Modules which lock down vulnerable door to interface wiring by only activating in response to an encoded digital signal generated by the AIM-4SL.
