The I/O-8 Module, used in conjunction with networked SHS systems, provides interface capabilities for a variety of peripheral devices. Each of the 8 ports can be programmed to function as either input or output, providing easy expansion capabilities without sacrificing space or increasing cost. The I/O-8 Module allows your resident/asset protection system to also operate as a perimeter security system. For example, a networked SHS system can monitor dry contact or voltage changes if the signal is connected to an input on the I/O-8 Module. Software not only allows Controllers and supervised Inputs/Outputs to be grouped into zones, but also provides timer functionality.
