1. Pengenalan
The Simplex 4090-9001 Individual Addressable Module (IAM) is a supervised device designed for use with Simplex IDNET fire alarm control panels. This module provides supervised monitoring of a normally open or normally closed contact, allowing the fire alarm system to monitor various external devices such as flow switches, tamper switches, or other alarm initiating devices. Its compact design and addressable capabilities ensure efficient and reliable integration into a comprehensive fire detection and alarm system.
This manual provides essential information for the proper installation, operation, and maintenance of the 4090-9001 IAM. Please read all instructions carefully before proceeding with installation or operation.
2. Maklumat Keselamatan
Always adhere to local codes, ordinances, and regulations when installing and operating this device. Failure to do so may result in property damage, injury, or death. Only qualified personnel should install and service this equipment.
Langkah berjaga-jaga am:
- BAHAYA ELEKTRIK: Disconnect electrical field power when making any internal adjustments or repairs. All repairs must be performed by a Simplex authorized service representative.
- PERHATIAN ESD: Do not open or service this device unless properly grounded. Electrostatic discharge (ESD) can damage components. Handle with care.
- Ensure all wiring is correctly terminated and secured according to wiring diagrams and local electrical codes.
- Do not expose the module to moisture or extreme temperatures outside its specified operating range. This device is intended for indoor dry applications only.
- Verify compatibility with your existing Simplex IDNET system before installation.

3. Persediaan dan Pemasangan
The 4090-9001 IAM is designed for easy installation within standard electrical boxes or compatible enclosures. Follow these steps for proper setup.
3.1 Pemasangan Fizikal
- Mount the module in a suitable electrical box or enclosure, ensuring it is securely fastened. The module is designed for indoor dry applications.
- Ensure adequate space for wiring and ventilation around the module.
3.2 Sambungan Pendawaian
Refer to the module's label and the specific installation instructions (part number 574-331 Rev G, as indicated on the module) for detailed wiring diagrams. The module features terminals for IDNET input/output and supervised contact connections.

- Connect the IDNET communication lines to terminals 1 (IDNET IN -) and 2 (IDNET IN +).
- Connect the IDNET communication lines to terminals 3 (IDNET OUT -) and 4 (IDNET OUT +) for daisy-chaining to other IDNET devices.
- Connect the supervised contact circuit to the designated terminals (typically M1 and the associated input). Ensure proper polarity and the use of an End-of-Line Resistor (EOLR) as specified by Simplex for supervision.
- All circuits are power-limited.
3.3 Menangani
The 4090-9001 is an addressable module. Its address is set electronically by the Simplex fire alarm control panel during system configuration. Refer to the control panel's programming manual for details on assigning and verifying module addresses.
4. Operasi
The Simplex 4090-9001 IAM operates as an interface between a supervised initiating device circuit and the IDNET communication loop of a Simplex fire alarm control panel.
4.1 Supervised Monitoring
The module continuously monitors the connected contact circuit for changes in state (open or closed, depending on configuration) and for fault conditions (e.g., open circuit, short circuit) using an End-of-Line Resistor (EOLR). Upon detecting an alarm condition (e.g., contact closure for a flow switch) or a fault, the module communicates this status change to the fire alarm control panel via the IDNET loop.
- Keadaan Biasa: The module reports a normal status to the control panel.
- Keadaan Penggera: When the supervised contact changes state (e.g., closes for an alarm), the module transmits an alarm signal to the control panel.
- Trouble State: If a wiring fault (open or short) is detected on the supervised circuit, the module transmits a trouble signal to the control panel.
5. Penyelenggaraan
The Simplex 4090-9001 IAM is designed for reliable, long-term operation with minimal maintenance. However, periodic inspection and cleaning are recommended as part of a comprehensive fire alarm system maintenance program.
5.1 Pembersihan
If the module accumulates dust or dirt, gently wipe the exterior with a soft, dry cloth. Do not use abrasive cleaners, solvents, or excessive moisture. Ensure the module is powered down before cleaning.
5.2 Pemeriksaan
During routine system inspections, visually check the module for any signs of physical damage, loose connections, or environmental stress. Verify that the module's status indicator (if present) is operating normally according to the system's operational guidelines.
