Simplex 4090-9001 – Refurbished

Description

Model 4090-9001 is packaged in a thermoplastic housing and provides screw terminal connections and a status indicating LED. Individual addressable modules (IAMs) receive both power and communications from a two-wire MAPNET II or IDNet circuit. They provide location specific addressability to a single initiating device (such as single station smoke detector alarm contacts or heat detector contacts) or multiple devices at the same location by monitoring normally open dry contacts and the wiring to an end-of-line resistor.
