Safety Information

WARNING: DISCONNECT POWER BEFORE OPENING OR SERVICING.

Installation and servicing of this device must be performed by qualified personnel only. Adhere to all local and national electrical codes and regulations. Failure to follow these instructions could result in property damage, serious injury, or death.

• Always ensure the fire alarm control panel (FACP) is powered down before connecting or disconnecting any modules.
• Verify all wiring connections are secure and correct according to the system's design specifications.
• Do not expose the module to moisture or extreme temperatures.

Product Overview

The Simplex 4090-9120 is a single-address, six-point input/output (I/O) assembly designed for integration into Simplex fire alarm systems. This module allows the fire alarm control panel to monitor and control up to six external devices or circuits, expanding the system's capabilities for detection and notification.

Key Features:

• Single address for efficient system integration.
• Six configurable input/output points.
• Designed for reliable performance within fire safety systems.

Components:

The module consists of a circuit board with terminal blocks for wiring connections, a central processing unit, and relays for output control. It is typically mounted within a compatible enclosure or panel.

Setup and Installation

Installation of the Simplex 4090-9120 module requires careful attention to wiring and system configuration. It is recommended that only certified fire alarm technicians perform the installation.

1. Power Disconnection: Before beginning any work, ensure that all power to the fire alarm control panel (FACP) and associated circuits is completely disconnected.
2. Mounting: Mount the 4090-9120 module securely within a compatible enclosure or panel, ensuring adequate ventilation and clearance from other components.
3. Wiring Connections: Refer to the specific wiring diagrams provided with your fire alarm system documentation for precise connection details. Generally, connections include:
   • Power Input: Connect the module to the appropriate 24V DC or 24V AC power source from the FACP.
   • IDNet Connections: Connect the module to the IDNet communication loop of the Simplex FACP.
   • I/O Points: Wire the external devices (e.g., smoke detectors, heat detectors, pull stations, notification appliances, or other control devices) to the designated input/output terminals (NC, COM, NO) on the module. Ensure correct polarity and supervision where required.
4. Configuration: Once wired, the module must be configured within the FACP programming. This involves assigning the single address and defining the function of each of the six I/O points (e.g., input for monitoring, output for control).
5. Power Restoration and Testing: After all connections are verified and the module is configured, restore power to the FACP. Conduct thorough system tests according to manufacturer guidelines and local codes to confirm proper operation of the module and all connected devices.

Operating Instructions

The Simplex 4090-9120 module operates as an interface between external devices and the fire alarm control panel. Its operation is largely automatic once properly installed and configured within the FACP.

• Input Monitoring: When configured as inputs, the module continuously monitors the status of connected devices (e.g., open/closed circuits, alarm conditions). Any change in status is reported to the FACP.
• Output Control: When configured as outputs, the module receives commands from the FACP to activate or deactivate connected devices (e.g., turning on a strobe, activating a relay for door release).
• Status Indication: The FACP will display the status of the module and its connected points. Refer to your FACP's manual for specific status indicators and messages.

No direct user interaction with the module itself is typically required during normal operation.

Maintenance

Regular maintenance is crucial for the reliable operation of any fire alarm system component, including the Simplex 4090-9120 module. Maintenance should be performed by qualified personnel.

• Visual Inspection: Periodically inspect the module and its wiring for any signs of damage, corrosion, loose connections, or environmental issues.
• Cleaning: Keep the module free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or solvents.
• System Testing: Follow the recommended schedule for fire alarm system testing as per local codes and manufacturer guidelines. This includes testing the functionality of all I/O points connected to the module.
• Firmware Updates: If applicable, ensure the FACP and connected modules have the latest compatible firmware. Consult Simplex technical documentation for update procedures.

Troubleshooting

If the Simplex 4090-9120 module or its connected devices are not functioning as expected, consider the following troubleshooting steps:

• No Power/Communication:
  • Verify that the FACP is powered on and that the module is receiving proper power (24V DC/AC).
  • Check IDNet wiring for continuity and correct connections.
• Input/Output Malfunction:
  • Inspect wiring to the specific I/O point for loose connections, shorts, or breaks.
  • Confirm the external device connected to the I/O point is functioning correctly.
  • Verify the module's configuration within the FACP matches the intended function of the I/O point.
• FACP Error Codes:
  • Consult the FACP's manual for specific error codes related to modules or IDNet devices.
  • An error code may indicate a specific issue with the module or its address.
• System Reset:
  • In some cases, a system reset from the FACP may resolve minor communication glitches.

If issues persist after basic troubleshooting, contact a qualified fire alarm technician or Simplex technical support.
