SIMPLEX 4090-9001 IDNET SUPERVISED IAM MODULE SD-651 It provides either a two-wire

It provides either a two-wire or four-wire fault-tolerant Initiating Device Circuit (IDC) for normally-open-contact fire alarm and supervisory devices

Relative humidity: 10% – 93% non-condensing

— B501BHT Intelligent Temporal Tone Sounder Base

This module provides an address for any device as well as group of devices connected to this circuit on the signaling line circuit (SLC) of the Gamewell-FCI addressable series fire alarm control panel

The fire alarm panel loop controller uses a proprietary communication protocol containing both digital and analog signals that allow each sensor to communicate its individual address

SIMPLEX 4090-9001 IDNET SUPERVISED IAM MODULE SD-651 It provides either a two-wireIndividual 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
