AutoCall A4090-9001 Supervised IAM Module

The AutoCall A4090-9001 is an IDNet individual addressable module that monitors normally open dry contacts on AutoCall IDNet systems. It provides single-point addressable supervision for initiating devices or contact circuits, with screw terminal wiring, a visible status LED, and a compact enclosed housing that mounts in a standard single-gang electrical box. Key Specifications: Type: Individual addressable monitor module Core Function(s): Monitors normally open dry contacts and wiring to an end-of-line resistor for location-specific addressable supervision Loop/Protocol: IDNet; 1 address per IAM Power: Powered by IDNet communications over a single wire pair Indicators/UI: Visible LED for communications status Wiring: Screw terminals for 18 to 14 AWG wire Mounting: Standard single-gang electrical box Distance to Contacts: Up to 500 ft without protectors; up to 400 ft with A2081-9044 overvoltage protectors Operating Range: 32 to 158 F for indoor use Humidity Range: Up to 93 percent RH at 100 F Compatible Accessories: A4090-9806 - Trim plate for semi-flush mounted box with LED viewing window A4090-9807 - Trim plate for surface mounted box with LED viewing window A4090-9810 - Mounting bracket required for optional trim plates A4081-9004 - 6.8 kOhm end-of-line resistor harness for standard N.O. contact supervision A4081-9003 - 4.7 kOhm resistor harness for current limited monitoring applications A4081-9005 - 1.8 kOhm resistor harness for current limited monitoring applications A2081-9044 - Overvoltage protector for outdoor or electrically noisy applications System Compatibility: AutoCall 4007ES, 4010ES, and 4100ES fire alarm control panels with IDNet communications
