To expand the line module input capacity of the controller, use the Alarm Expansion Board (AEB8). These provide an additional 8 line module inputs per board.
Expansion line module inputs are used for a variety of security monitoring functions. In intrusion detection applications, they normally monitor interior motion sensors, perimeter doors and windows for forced entry or intrusion into a protected area; however, they are generally not employed for door access control applications.
Each line module input, whether connecting to a base alarm on the controller board or an expansion alarm on an AEB8, must be routed through a line module.
Up to four AEB8s can be installed in a controller.

The wiring and settings of the AEB8 are shown in Figure 4-2.

As Figure 4-2 shows, the shield should be floated at the line module. Also, it is recommended that line module inputs be wired NC.
The AEB8 has four address jumpers. Each jumper allocates a range of eight addresses. This addressing scheme enables up to four AEB8's to reside in one controller. (For the M16, which has 16 inputs on the base controller board, two additional AEB8s can be added to the controller for a total of 32 inputs.)
