Usually leaves our warehouse the same business day.
The ADEMCO 4190SN an addressable two-zone expander that can create additional zones capable of supporting VPlex devices. The 4190SN features two detection loops (left and right). The left (primary) is used for closed-circuit devices with or without EOLR supervision, open-circuit devices with EOLR supervision, and fast-response devices (10 millisecond). The right loop supports closed-circuit devices, offers no EOLR supervision, and a 400 millisecond response time.
Jumpers and resistors must be chosen correctly for the left loop, but jumpers have no effect on right-loop operation.
