ASP-IO168 Downstream Input Output Board

The ASP-IO168 Alarm Input/Output Module features 16 Alarm Input and 8 output relays, all fully configurable with advanced options for a full featured alarm monitoring and/or elevator control system. Dependable multi-level functions as well as off-line functionality insure reliable, robust protection from intrusion as well as monitoring status of site devices.

This new I/O module is a direct substitute for the previously discontinued AIO-168 Alarm Module and the AIM-1ELE Elevator. This new industry leading Alarm Input/Output module provides features not found anywhere else. the ASP-IO168 supports both OSDP and Proprietary protocols both fully encrypted ensuring secure communications. 

The ASP-IO168 comes with multiple assembly options to best suit the needs of different sites, relative to the number of devices connected to the I/O module, the ASP-IO168 consumes minimal power and can even be powered by PoE (Power over Ethernet).

A combinations of software and hardware filtering suppresses noise and eliminates false alarm, preventing annoying and costly false alarms. Supervised mode allows the ASP-IO168 to monitor input line status in order to prevent tampering with wiring to defeat alarm input devices. Input supervision reports short or open conditions on the line by using a standard end-of-line resistor or for higher security applications, custom resistor values are available.

For interfacing to external devices such as annunciation sirens and indicator lights, the AIO-168 features 8 Form-C relay outputs. Each output can be individually configured for local linkage to any combination of the ASP-IO’s 16 input zones as well as line tamper condition, cabinet tamper condition, communication loss or power supply interruption even in an off-line state. Further relay control can be programmed in ASP Family controllers or in the software host to provide relay function in a virtually unlimited number of circumstances.


Each relay output can be controlled by a combination of the following 21 conditions: 

  • Alarm inputs 1-16
  • Power fault
  • Cabinet tamper
  • Any zone fault
  • Host comm loss
  • Time zone control

Any of the above conditions can initiate one or more relay outputs. A different time zone can be specified for each auxiliary relay output.


The AIO is available in ten base configurations and with an optional 8 relay add-on board for flexibility in designing any system.
