prolonged storage.
Input and output connections are located on the AM-255 board. There are two 5 pin terminal
strips for alarm input connections from the portal Monitors. There are also two 12 pin terminal
strips to provide connections to an external alarm system.
To install the AM-255, use the following procedure.
NOTE: Due to varying site requirements, the cable between the AM-255 and the system to be
monitored is not shipped with the AM-255. Any commercial quality, five conductor, 22 ga,
signal cable may be used.

Connect the cables from the portal monitor to the alarm input connections. Information
on portal monitor alarm connections can be found in the Operating and Service Manual for that
monitor. Next loosen the two screws at the bottom corners of the front panel and open the panel.

Connect the alarm output cables as required. The AM-255 will operate properly with or without
these connected.
