Supervised IAM, Mounted in Thermoplastic Housing w/ Screw Terminals.

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.

Model 4090-9001 is packaged in a thermoplastic housing and provides screw terminal connections and a status indicating LED.

IDNet or MAPNET II addressable communications supply both data and power over a single wire pair to provide:

  • Supervised Class B monitoring of normally open, dry contacts
  • Total wiring distance from IAM to supervision resistor(s) of up to 500 ft (152 m)
  • Monitored connection is compatible with Simplex 2081-9044 Overvoltage Protectors for outdoor wiring or electrically noisy applications
  • For use in indoor locations up to 158° F (70° C) such as attic spaces or similar applications
