I see that my new securityProbe 5E is expandable using these four expansion ports on the front of the unit and these new expansion modules? What types of modules are available?

AKCP AdministratorsecurityProbe Series, Support

We offer two types of expansion modules. The first is the E-sensor8 expansion module and it has 8 RJ-45 Intelligent sensor ports just like the ports on the back of the main securityProbe 5E unit. The second is the E-opto16 expansion module and it has 16 dry contact inputs just like the extra dry contacts on the securityProbe8-X20 units.
