Addressable Security IAM Module 4090-9121

Addressable Security Monitor IAM – Model 4090-9121

The 4090-9121 Security Monitor IAM is an individual addressable module (IAM) designed to monitor security devices such as door/window magnetic contacts or other dry-contact devices within a fire alarm and security monitoring system. It is compatible with Simplex/Autocall fire alarm control panels 4100ES, 4100U, and 4010ES via the IDNet communication line.

The module can distinguish different monitored contact states: Open, Normal, Abnormal, and Short.

Key Features

• For use with Simplex® 4100ES, 4100U, and 4010ES fire alarm control panels with IDNet™ communications.

• IDNet communication provides both data and power over a single pair of wires.

• Monitors a Class B circuit of N.C. (normally closed) or N.O. (normally open) dry contacts.

• Monitored states: Open, Normal, Abnormal, Short.

• Abnormal condition occurs when supervisory current changes by ±50%.

• Maximum distance between IAM and monitored contact: 152 m (500 ft).

• Sealed design reduces dust; fits in a standard single-gang electrical box.

• Flashing LED indicates communication; optional trim plate allows LED viewing after installation.

• UL listed to UL 1076 Security standard.

Operation

• Each IAM 4090-9121 can monitor up to 5 devices (e.g., door/window magnetic switches or other security contacts).

• Armed mode (typically after-hours): Open, short, or abnormal conditions trigger a Priority 2 Alarm at the fire alarm control panel.

• Disarmed mode (typically during business hours): Abnormal conditions are reported as events or troubles, depending on configuration.
