FireClass
FC410DDM – UNIVERSAL FIRE AND GAS DETECTOR MODULE
DESCRIPTION
The FC410DDM provides the ability to connect and interface 2 zones of 20 V
DC 2-wire conventional fire detectors, or two 4-20 mA signalling sensors, to
the FireClass fire alarm controller.
The FC410DDM monitors the status of the detectors and the wiring to the
detectors and signals detector and wiring status back to the controller.
The conventional detector circuits can be configured in one way:
Ø To monitor 1 or 2 Class B spur circuits
The 4-20 mA signalling sensors may be one of two types:
Ø Current sinking
Ø Current sourcing

Electromagnetic Compatibility
The FC410DDM complies with the following:
– Product family standard EN 50130-4 for immunity
– EN 61000-6-3 for emissions
ADDRESS SETTING
The FC410DDM has a default factory set address of 255, that must be set to
the loop address for the device. The FC410DDM may be programmed prior
to installation by using the FC490ST Service Tool and the internal program-
ming port (see Fig. 1).
+
This device use one address only on the loop.
+
Note: Once the address has been programmed, take note of the device
location and address number, to include on site drawings.

CABLING
Cables are to be selected in accordance with the system design document
and the requirements of the applicable standards.
The maximum section of the cable that can be connected at any one termi-
nal is 2.5mm 2 .The section is calculated based on the characteristics of the
cable and the load.
