AIO-168 Analog Input Alarm Module

The AIO-168 Alarm Input/Output Module features 16 Alarm Input Zones and 8 output relays, all fully configurable with advanced options for a full featured alarm monitoring 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.

The AIO’s 16 highly sensitive input zones are scanned up to 180 times per second in order to detect alarms other systems miss. In addition, input data is filtered for noise rejection, preventing annoying and costly false alarms. Supervised mode allows the AIO 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 SPDT outputs. Each output can be individually configured for local linkage to any combination of the AIO’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 AAN/AAM series controllers or in the software host to provide relay function in a virtually unlimited number of circumstances.

AUXILIARY OUTPUT LINKAGE

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.

OFF-LINE ALARM EVENT STORAGE

When the AIO-168 is on-line with the host, status changes (alarm inputs) are sent immediately to the host on thenext interrogation/response sequence. When the AIO-168 is off line, up to 100 alarms are stored in a FIFO log alarm event buffer. At least one alarm event for each zone that was in alarm since the AIO-168 went off-line is saved.

STORED EVENTS CONTAIN:

• Time of event
• Alarm zone number
• Alarm zone status after change
• Alarm zone status before change
