Simplex 4090-9007 Signal IAM

Simplex 4090-9007 Signal IAM

Signal IAM (Signal Individual Addressable Module) is a module (IAM) used in the Simplex addressable fire alarm system, connecting the fire alarm control panel (FACP / FACU) with notification appliances such as horns, strobes, speakers, etc.

Purpose:
Provides a supervised output for Notification Appliance Circuits (NACs) with its own address, enabling remote signaling control and expansion of NAC zones when needed.

Key Features

• Supervised NAC expansion module for addressable fire alarm panels 4007ES, 4008, 4010ES, 4100ES, 4100U.

• Allows adding local alarm zones (selective signaling) without requiring a separate power supply.

• NAC Output:

  • 0.5 A for 24 VDC notification appliances (special application / regulated).

  • 12.5 W @ 25 VRMS or 35 W @ 70.7 VRMS for speakers (audio).

• Supports Class A or Class B supervision.

• Flashing LED indicates communication status.

• Does not support SmartSync or TrueAlert addressable control (only for 4-wire devices).

• Compatible with Simplex strobe synchronization.

• Powered directly from the IDNet loop (no separate 24 VDC supply required for the module).

• Listings/Approvals: UL 864, ULC, CSFM, FM, MEA (NYC).

Technical Specifications

Electrical

• Communication: IDNet, uses 2 logical addresses (though physically one address).

• NAC Input Power:

  • 24 VDC from FACU NAC or NAC extender.

  • 25 VRMS or 70.7 VRMS from compatible audio source.

• NAC Output:

  • 0.5 A @ 24 VDC (notification appliances).

  • 12.5 W @ 25 VRMS or 35 W @ 70.7 VRMS (speakers).

• End-of-Line (EOL) resistor: 10 kΩ, 1/2 W (part no. 4081-9008).

• Wiring connections: Screw terminals, 18–12 AWG (0.82 – 3.31 mm²).

Wiring Distance

• IDNet: up to 2,500 ft (762 m) from FACU.

• Total Class B wiring (including T-taps): up to 10,000 ft (3,048 m).

• NAC: wiring distance depends on voltage drop, conductor size, and device load (IAM itself does not significantly affect voltage drop).

Mechanical

• Dimensions: 102 × 105 × 32 mm (4” × 4 1/8” × 1 1/4”).

• Operating temperature: 0°–49 °C (32°–120 °F), indoor use only.

• Humidity: ≤ 93% RH @ 38 °C (100 °F).

• Mounts in a standard 4-inch square electrical box, minimum depth 54 mm.

Optional Accessories

• 4090-9801: Semi-flush trim plate with LED viewing window.

• 4090-9802: Surface-mount trim plate with LED viewing window.

• 4090-9116 / 4090-9122: IDNet Isolator, for loop branch isolation.

• 4081-9008: 10 kΩ, 1/2 W End-of-Line resistor.

• 2081-9044: Overvoltage Protector for IDNet wiring.
