FDM-1 Dual Monitor Module: Enhanced Monitoring Capability

The FDM-1 Dual Monitor Module is designed for use in intelligent two-wire systems, offering expanded monitoring capabilities with two independent 2-wire initiating device circuits (IDC) assigned to consecutive addresses. Here are the key details:

General Description:

• Dual Monitoring: Provides two separate, independent 2-wire IDCs, each with its unique address.
• Versatile Compatibility: Capable of monitoring normally open contact fire alarm and supervisory devices, as well as normally open or normally closed security devices.

Specifications:

• Normal Operating Voltage: Supports a range of 15 to 32 VDC.
• Maximum Current Draw: Consumes 6.4 mA (LED on).
• Average Operating Current: Draws 750µA (LED flashing).
• Maximum SLC Wiring Resistance: Allows up to 40 Ohms.
• EOL Resistance: Equipped with a 47K Ohms resistor.
• Maximum IDC Wiring Resistance: Permits up to 1,500 Ohms.
• Maximum IDC Voltage: Handles a maximum of 11.0 Volts.
• Maximum IDC Current: Operates with a maximum current of 240 µA.
• Temperature Range: Suitable for temperatures ranging from 32°F to 120°F (0°C to 49°C).
• Humidity: Operates efficiently within a humidity range of 10% to 93%, non-condensing.
• Dimensions: Compact dimensions of 4.675˝ in height × 4.275˝ in width × 1.4˝ in depth, designed to mount to a 4-inch square by 21/8-inch deep box.
• Accessories: Compatible with SMB500 Electrical Box for installation convenience.

The FDM-1 Dual Monitor Module enhances monitoring capabilities within intelligent two-wire systems, offering flexibility and reliability in monitoring a variety of devices. Its dual IDCs, compatibility, and robust specifications make it a valuable addition to such systems.
