Tyco DDM800 Universal Fire & Gas Detector Module 577.800.006

Tyco DDM800 Universal Fire & Gas Detector Module 577.800.006

The Tyco DDM800 (577.800.006) Universal Fire & Gas Detector Module an MX addressable module designed to monitor and signal alarms from:

• One or two conventional 2-wire detector circuits, or
• One or two 4-20 mA sensors*

Tyco DDM800 module used to connect two circuits of conventional 20V detectors and interface them with an MX addressable fire alarm system. These circuits are compatible with a wide range of detectors, and include support for fast alarms on 15V Indicating Manual Call Points (MCP), Intrinsically Safe isolators and detectors, and AVF on smoke detectors.

The Tyco DDM800 can be MX Loop-powered or use an external 24Vdc power supply. When loop-powered a special low voltage mode used with the Tyco 614 series detectors for operation over the full voltage range of the MX Loop.

Using an external 24V supply allows a wide range of detectors to be connected, and for the detector circuits to be electrically isolated from the MX Loop.

In 4-20mA mode the Tyco DDM800 can support a single 4-20mA source (e.g., gas sensor, flame sensor) on each circuit, operating in either current sink or current source mode*. The DDM800 has an insertion loss of 4V, providing compatibility with a wide range of sensors from a 24V supply.
